together , they plan to go after major urban design projects around the world , something rtkl has made great strides toward , particularly in china , noy said .
rtkl , which traces its founding to 1946 , was bought by arcadis in 2007 . its portfolio includes projects in the middle east , china and south america .
by 1961 , mr . rogers had three partners , mr . taliaferro , george kostritsky and charles lamb . the initials of their last names gave rtkl its firm .

the fourth partner was george kostritsky , who joined the firm in 1961 and stayed until the early 1970s . in the mid - 1960s , an exasperated receptionist shortened it to rtkl .
rtkl has about 225 employees in its downtown baltimore headquarters and more than 900 employees in offices in washington , dallas , los angeles , london , tokyo , hong kong and madrid .
howard associates , of sylvania , ohio usa is an internationally recognized architectural illustrating firm assisting architects , developers and builders in communicating architectural concepts to a diverse and generally non - architectural clientele . illustrations of notable building projects that have attracted attention to howard associates include : 3 times square - reuters headquarters , citicorp center in new york , jeddah international airport in saudi arabia , the ronald reagan presidential library in ventura county , california and expansions to the metropolitan museum of art , new york , the museum of modern art , new york and our national capitol in washington d . c . toll - free . 1 - 800 - 605 - 5182
the firm grew significantly after 1967 , when the founders hired harold adams to manage the business . they named him president a year later . adams was instrumental in launching rtkl ' s international initiative .
even as rtkl gained work around the world , it remained active in baltimore . today , the city is a veritable museum of its work , with dozens of major projects complete or under way .
we see miami really as the capital of south america , and we will be moving our work in south america to the miami office ,
said david c . hudson , president of rtkl .
howard snoweiss , the founder of the acquired firm , was named senior vice president of rtkl and will lead the firm ' s miami operations , hudson said . terms of the deal were not disclosed .
harold l . adams , who spent more than 35 years at rtkl and is credited with helping to elevate the firm to the international prominence it holds today , had mixed emotions over yesterday ' s news .
the 54 - year - old firm conducts about 95 percent of its work outside baltimore , hudson said . rtkl was recently ranked the fifth - largest architectural firm in the world by world architecture magazine , he said .
rtkl chairman paul jacob iii said the firm had been thinking about pursuing a merger for some time as a means to grow more rapidly globally . it hadn ' t considered being acquired until arcadis came along with an unsolicited offer .
, served as vice president at rtkl associates ( 1996 - 2003 ) and brown craig turner architects ( 2003 - 2006 ) . in that capacity , he directed such notable projects as the fashion center at pentagon city , bowie town center , peabody place , and arkadia center in warsaw , poland . jamie brings more than 30 years of experience in design and documentation of major commercial mixed use and retail projects . he has directed the design and delivery of numerous facilities for clients such as simon property group , forest city enterprises , general growth properties and others . he holds a degree in architecture from carnegie - mellon .
between 1967 and november 2003 , adams served in a variety of roles at rtkl , including president , ceo and chairman . it was a period when the company ' s employment base grew from 45 to 1 , 000 , he said .
the merged enterprises will be headquartered in baltimore and led by dallas - based ceo lance josal , formerly of rtkl . he said in an interview that the company , which employs about 350 in seattle , doesn’t expect any layoffs as a result .
hudson , who is only the second president of rtkl , said the privately held firm ' s revenue was $ 108 million in 1999 . revenue for this year is projected at $ 130 million , a figure that does not reflect this latest acquisition .
in 1965 , a month before entering graduate school at carnegie mellon university , bowden married his childhood sweetheart , sandra , with whom he has three children . after college , bowden taught design for three years at hampton university . then he joined rtkl .
no one [ in baltimore ] knew who the freelon group was ,
he explains .
i felt that i needed a strong local presence . if rtkl didn ' t want to do it , i wouldn ' t have pursued it .
arcadis plans to keep rtkl intact as a subsidiary , with existing management and staff in place , and has vowed to invest capital in the firm to help it grow . at first , rtkl officials were skeptical , jacob said , especially since the industry has seen a spate of mergers and acquisitions lately and the firm had received several overtures already . but after speaking with other subsidiaries that arcadis had recently acquired , jacob and the other vice presidents who held the company ' s shares realized arcadis meant what it said .
bowden and freelon are two of the very few african - americans inducted into the prestigious college of fellows of the american institute of architects . as the highest ranking african - american at rtkl , bowden has been a mentor to young employees of all races and nationalities .
in more than three decades with rtkl , bowden had worked throughout the united states and in nearly a dozen foreign countries . the closest he had come to working in baltimore city was a series of retail projects in baltimore county - , the avenue at white marsh and ikea .
two of the principals , bowden says , suggested early on that he might be a good fit for rtkl ' s planning studio , working with inner - city communities . but bowden chose retail design ,
where i knew there would be no advantage [ to being black ] .
the new name , callisonrtkl , formally cements the marriage between callison and baltimore - based rtkl , two well - known names in the architecture world that together booked $ 402 . 4 million in architecture and engineering revenue last year . architectural record recently ranked the combined firms fifth in the nation .
rtkl is a great place to start your career . it affords those just starting out the opportunity to get exposure and hone their skills . it is also a great place to hold up if you ' re between opportunities but do not plan on getting comfortable unless you know the right person .
over its six decades , rtkl has left a lasting imprint on the baltimore area , designing buildings large and small and helping to shape the city ' s revitalization . when baltimore initiated downtown renewal , rtkl designed the master plan for charles center and later was heavily involved in the emergence of the inner harbor . among its buildings are the hyatt regency hotel , one of the early structures to rise along light street ; the tower at 750 west pratt , now headquarters of constellation energy group ; and the reginald f . lewis museum of maryland african american history and culture , which it co - designed .
rtkl has designed numerous buildings in baltimore , including the new alex . brown building , where it is headquartered , and the hyatt regency hotel . the firm ' s work covers a billion square feet in 60 countries , and its projects include retail and entertainment centers , government buildings and health care facilities .
our founding partners met at the university of texas at austin in the 1970 ' s and became good friends . following graduation , tim blonkvist worked with i . m . pei in new york city ; rick archer moved to washington , dc with shalom baranes associates ; madison smith earned an mba in real estate and worked with developer trammell crow ; and robert schmidt utilized his engineering and construction background with gerald hines in dallas . in 1982 the four friends committed to a lifelong friendship and the start of a business .
in baltimore , rtkl was heavily involved in both charles center and the inner harbor , said martin millspaugh , former chief executive of charles center - inner harbor management inc .
their work is all over downtown . . . . they ' ve been a strong thread from the beginning right though until today .
depending on the department , rtkl is not a place in which one is allowed fair opportunity for growth . there are no clearly defined processes , no metric system to measure career growth and nepotism is blatant . if you want career growth , have a social relationship with upper management because hard work and dedication is not recognized .
bowden says he didn ' t think it would be appropriate for maryland ' s african - american museum to be designed solely by rtkl because it wasn ' t an african - american firm . but he was open to the idea of working in partnership with an african - american designer and tried to determine who would be best .
a kinetic shade structure for the new robert b . green clinical pavilion in san antonio . composed of 5029 tilted aluminum vanes that sway in the wind , the artwork seeks to dissolve the boundary between architecture and atmosphere , linking the building to the ever - changing and normally invisible currents of air . developed in collaboration with overland partners and rtkl architecture .
not innovative enough in terms of design , though the corporate level pushes so . cost driven , profit driven , few projects could make you really proud as being an architect . low pay , even consider the longer pto , if i convert the extra pto into value based on rtkl standard , my salary is still way lower than other firms in market .
freelon , meanwhile , says he decided it would make sense to work with a maryland firm that knew the local players and had a feel for the site . he had been familiar with rtkl since his days at mit , when the firm offered him a job . he also knew and respected bowden and felt they would be able to work well together .
with 1 , 100 professionals and support staff in 10 offices and gross revenue of $ 195 million last year , rtkl has been involved in high - profile projects around the world . it redesigned the portion of the pentagon that was damaged during the sept . 11 terrorist attacks . internationally , it was on the design team that helped beijing win the 2008 summer olympics .
by the mid - 1980s , phil freelon was making a name for himself at o ' brien atkins associates , a large architecture firm in north carolina ' s
research triangle ,
but longed for more responsibility . in 1989 , he took a leave of absence to become a loeb fellow at harvard university . while there , he wrote a business plan for a firm he envisioned starting , a company that would emphasize diversity and have offices up and down the east coast . while planning his ideal firm , he noted the need for institutions that would celebrate african - american heritage - and the opportunities for architects who designed their homes .
with the opening drawing near , the architectural work is essentially complete . freelon is focusing on other projects and building a national practice . bowden retired from rtkl in 2001 and teaches architecture at the university of maryland , college park , where he was just named the kea distinguished professor . he also serves on the city ' s urban design and architectural review panel , which critiques designs for key projects around the city .
the quality and detail for which rtkl is known for in their designs is shown masterfully in their 63 , 000 - sf washington , dc office . highlighting the architects ' space is a reclaimed historic heart pine stair system contrasted by an adjacent two - story interlocking sculptural wall system . the reclaimed wood and the client - purchased lighting package had substantial lead times , but hitt’s due diligence in tracking the items allowed all materials to arrive earlier than expected . the entrance features a span of custom frosted acrylic panels with rtkl’s logo sandblasted into them and backlighted with an innovative energy conserving led lighting system . one of the challenges of the project was completing the project with very limited resources ; close coordination was involved with work in retail shops and a bank below the project floor . designed to meet the highest sustainable certification , this project reached leed platinum certification .
throughout the space , technology is celebrated via the use of projection animations , monitors with rotating images that perpetuate the firm’s core services and values . large - scale graphics applied to conference room glass walls promote privacy and visibility . in the entrance foyer , identity signage promotes low - energy use , company pride , and brand identity : a superscaled version of the stenciled rtkl wordmark is rendered via a translucent resin wall backlit by color - changing leds .
george kousoulas has over three decades of experience in the architecture , construction , and development fields . as an architect he has played key roles in the successful completion of major projects including the walter e . washington convention center in washington , d . c . , the luxor hotel and casino in las vegas , and brickell world plaza in miami . mr . kousoulas was previously a principal in the washington , d . c . office of the global architecture firm rtkl .
arcadis has more than 11 , 500 employees , including 3 , 700 in the u . s . last year , the publicly traded company reported revenue of 1 . 2 billion euros . the company , which has operated in the united states for a half - century , has added 2 , 500 employees and 80 offices here in just the past five years , mostly through acquisitions . this year the company had a goal of adding 1 , 000 , which it should accomplish with the acquisition of rtkl .

arcadis , which specializes in environmental remediation , infrastructure and property development , announced yesterday that it had bought the privately held baltimore firm for an undisclosed sum .
it ' s much more difficult to expand globally than across the nation ,
jacob said .
while we certainly had success , the pace at which we had been going was slow .
its influence pushes east and west . it created the master plan for the camden yards sports complex and is the architect for the hilton convention hotel now rising next to oriole park . and as development migrated eastward , it drew the plans for the bond street wharf in fells point and then moved in , forsaking the soaring tower it had designed at south and baltimore streets . it employs about 150 there now .
its reach extended to baltimore ' s suburbs and beyond . in the 1950s , it designed the east coast ' s first enclosed shopping mall , harundale , in glen burnie for developer james rouse and decades later fashioned the avenue at white marsh , the first
main street
type retail center in the baltimore region . its work also includes the greater baltimore medical center in towson and the episcopal church of the redeemer in north baltimore .
harrie noy , chief executive officer of arcadis , said there is no reason to make changes ; the company has built a brand and reputation globally that he has long admired from afar .
we think the combination of our businesses will benefit both of us ,
noy said .
there ' s a great deal of consolidation going on in all businesses ,
he said .
it does not surprise me , but it does surprise me . we had been fiercely independent and wanted to stay independent for many years . [ but ] the growth of other companies in the international marketplace is almost mandating this .

its contributions range from office towers such as one south street and charles center south to shopping centers in owings mills , white marsh and towson , and from the greater baltimore medical center to the hyatt regency baltimore hotel and the soon - to - open downtown hilton .
many of its former employees have started design firms or otherwise assumed influential roles , including baltimore development corp . president m . j .

the company was founded in 1946 by princeton graduate archibald coleman rogers in the basement of his grandparents ' house at 49 college ave . in annapolis . rogers painted the sign : archibald coleman rogers , registered architect . within a month , he was joined by francis t . taliaferro , who soon became a partner .
we opened at 8 : 30 on the morning of july 1 ,
rogers , who died in 2001 , recalled in a 1996 interview .
i designed the sign , painted it and hung it up . it was my first architectural project .
work came in gradually at first - a house in severna park , a storefront in annapolis , a county school . in 1949 , the partners hired charles lamb , an architecture student who became full - time a year later .
the firm was renamed rogers , taliaferro & lamb in 1956 . rogers was the rainmaker and urban designer , lamb the chief designer , and taliaferro the glue that held the office together . it moved to baltimore in the 1950s .
as the years passed , the architects began to win awards and bigger commissions . one breakthrough project was
the tepee
- a 12 - sided , cone - shaped lodge for girl scouts built in 1952 in anne arundel county . it won a national design award , the company ' s first . in 1954 , when noted architect pietro belluschi was chosen to design a new sanctuary for the episcopal church of the redeemer in baltimore , he asked rogers and his partners to be his local architects , largely because he was so impressed by the tepee .
the architects secured another significant commission in 1954 when developer james rouse hired them to design harundale mall in anne arundel county . it was the beginning of a long and profitable collaboration .
his vision and his firm helped transform the city ' s aging business district and once - moribund inner harbor . he also attained architecture ' s top professional honor , the presidency of the american institute of architects , in 1973 .
arch was one of those people who had great vision ,
said francis t . taliaferro of santa monica , calif . , his first partner .
he was always leading us over the next hill . he coined the phrase ` urban design . ' he came into cities that were in a planning mess and was able to leave them with a clear path .
born in annapolis , he spent summers at his grandparents ' home adjacent to president franklin d . roosevelt ' s residence in hyde park , n . y .
he earned architectural degrees from princeton university and , after service as a naval architect during world war ii , opened a small architect ' s office in his grandmother ' s annapolis home .
we would open at the office at 9 ,
mr . rogers told the sun in a 1996 interview .
if no one showed up by noon , we went sailing . best days of our lives .
in 1946 , he was named anne arundel county ' s first zoning commissioner , a job that placed him at loggerheads with the eight county commissioners , who overruled him in the case of a ritchie highway gas station in 1952 . mr . rogers resigned in protest , saying ,
i don ' t want ritchie highway to become another washington boulevard .
the stand won him accolades from newspaper editorial writers .
developer james w . rouse , for whom mr . rogers ' firm created harundale mall , tapped him in 1955 as the new greater baltimore committee ' s first executive director , a post he held for a year when the city was initiating downtown urban renewal .
he was a very valuable person , the right man at the right time to get the gbc started ,
said walter sondheim , the committee ' s senior adviser .
he was a genial man with a nice sense of humor . he cared very much about the quality of his work and that of his firm .
mr . rogers went on to head the city ' s urban design concept team , a group of engineers and planners charged with routing interstate highways through baltimore . mr . rogers opposed major sections of those highways for reasons of aesthetics and neighborhood preservation .
mr . rogers went on to consult on development in several other cities , including cincinnati , hartford , conn . , and eugene , ore . , and lectured around the world .
friends recalled mr . rogers as a
victorian gentleman
who liked to tell a good story . he wore yellow roses as a boutonniere on his navy blue blazer , accompanied by signature yellow or plaid trousers .
after retiring in the early 1980s , he spent his time at belvoir , a 400 - acre , 17th - century crownsville plantation overlooking round bay that his father bought in 1919 .
a voracious reader , he loved the study of words . a crossword puzzle he designed was published in the new york times . he wrote three novels , the monticello fault , and the walls came tumbling down ( a treatment of the pruitt - igoe public housing project in st . louis ) and the house of god . until this year , he had been writing his memoirs in the form of a novel .
mr . rogers ' wife of 37 years , the former lucia bernadine evans , died in 1984 .
a memorial service will be held at 11 a . m . dec . 15 at memorial episcopal church , 1407 bolton st . , where he was a member .
he is survived by his wife of 17 years , the former eleanor merryman roszel ; a son , coleman rogers jr . of wilmington , del . ; a daughter , lucia rogers - murdock of annapolis ; a brother , samuel b . rogers of coldspring harbor , n . y . ; a sister , margaret ann sappington of columbia ; and two grandsons .
firm that changed face of md . architects : fifty years ago . . .
the firm - howard snoweiss design group - has about 55 employees and focuses on designing hotels , resorts , corporate interiors , cruise ships , and entertainment and retail complexes .
we clearly have a corporate strategy of diversifying our business across all of the real estate markets and around the world ,
hudson said .
we ' re excited because this group does something very different than we do ,
said hudson .
we see the cruise ship industry as a major market in hospitality , both the ship side and the land side .
alan reed , president - elect of the baltimore chapter of the american institute of architects , said he ' s been seeing more architectural firms looking abroad over the past 10 years .
it seems like it started in hong kong and japan ,
said reed , a principal at grieves , worrall , wright & o ' hatnick inc .
it seems like the foreign countries are attracted to american architects , and this country is attracted to foreign architects .

the design team began with an extensive immersion process to understand its company culture and work processes . from this process , five core types of functional spaces or “activity zones” emerged : greet , seat , meet , eat , and retreat . environmental graphics were developed to complement and reinforce these spaces and themes .
egd elements celebrate teaming and partnerships by incorporating all forms of media ( from signage and digital animation to printed collateral material and large - scale wall graphics ) and by demonstrating a collaborative process among designers of various disciplines and services ( graphics , lighting , environmental media , interiors , etc . ) .
graphics were inspired by the concept of “done by hand . ” the team wanted to create a look and feel that showed personality and process—a personal touch that one would expect to find in a creative environment prior to the advent of computers . almost sketch - like , the graphic content throughout the space is light - hearted and playful , including illustrative wayfinding and back - of - house signs and fun bathroom mirror graphics that illustrate proper hand - washing techniques .
a major challenge was researching and specifying materials that are sustainable or include sustainable elements , while also being durable and fitting within the project budget . the team saw this as a unique opportunity to discover new materials , new application techniques , and new technologies .
environmentally preferable materials used in the egd elements include sustainable adhesives for the wall coverings , low - voc finishes for wall plaques and overhead signing , substrates and materials for large - scale graphics , collateral materials such as personal metal water canteens to reduce waste , low - energy digital rotating bulletin board announcements to convey office - wide accomplishments and information , as well as magnetic bulletin boards to reduce office paper distribution and consumption . recycling signs promote responsible trash separation and disposal of recyclable material .
“in a moment when digital media has come to replace the hand drawing that typified architecture in the past , these designers found a way to combine a very contemporary color and visual sensibility with the judicious use of witty , hand - drawn iconography , with great success . a balanced blend of left brain and right brain—evident in all good design—is here and available to all visitors , clients , and the employees themselves . ”

here is the observed signal on the pin . this is a netduino plus 2 , which runs at 168 mhz , the other netduino variations all run at different speed .
first experiences with the new netduino go , and how it relates to . net gadgeteer
netduino was a incremenatal version of the netduino plus and it has 4 times more speed than the netduino plus , this is 168 mhz instead of 48 mhz , also more code space and ram making it the most powerful netuino in the lineup as of now .
netduino is also pin compatible with arduino shields . drivers are required for some arduino shields .
head over to the netduino mini beta forums and flash the board with the latest firmware .
here are some quick tips on getting up and running with your netduino mini . . .
* you will see the netduino mini reboot and start sending debug data over the port .
* remove the secretlabs . netmf . hardware . netduino . dll reference from your project .
i created a simple visual tutorial on setting up a development board for the netduino mini .
by connecting a wire between the 3 . 3v header and the erase pad , you will erase your netduino completely . netduino is designed to be hacker - friendly and the erase pad lets you start over from scratch or repurpose your netduino as an arm microcontroller development board .

this is an article in effort to share my learning about netduino plus 2 with the examples .
it would be great if the three timer / counters in the netduino arm7 cpu were exposed .
check out the getting started guide for more information on how to get started with the netduino .
the netduino mini will reboot and will start sending debug data over the port at that point .
edit : fixed link to netduino mini beta forum with firmware 4 . 1 . 1 beta 1
“head over to the netduino mini beta forums and flash the board with the latest firmware . ”
netduino mini is programmed via a serial cable ( rs232 or ttl ) instead of via usb .
this post looks at the new netduino go and briefly compares it to the . net gadgeteer ( cerebus and others ) . i also build a couple simple example applications using the netduino go kit .
in general , the computing power of the netduino range is higher than that of arduino . with some netduino models working with a 32 - bit processor running at up to 168 mhz and plenty of ram and flash memory to spare , the netduino is appreciably faster than many of its arduino counterparts . this additional power comes with a larger price tag , although netduino costs per unit are not prohibitively more expensive . these costs can up mount , however , if netduino units are needed at scale .
microsoft provides free software tools to create netduino apps . all you need to get started is a netduino , a computer , and your imagination . as you progress through the projects in this book , i’ll introduce expansion shields and electrical components that you can add to your netduino to create larger projects .
netduino mini combines 16 gpios with spi , i2c , uarts , 4 pwm and 4 adc channels .
it seems like the netduino go with multiple shield bases ( image ) is the way to go .

hi mitch , the
getting started with netduino
book is written with . net mf 4 . 1 in mind , so i ' d probably pick up a traditional netduino to get started . that said , netduino go is the new flagship model . they look lovely next to each other . ; ) chris
here are the full instructions for upgrading a netduino mini to . net micro framework v4 . 2 : urltoken
do you already have your netduino 3 board ? discuss projects , gen3 hardware , azure support , etc .
it would be great if the three timer / counters in the netduino arm7 cpu were exposed . . .
the blue user led turns on briefly when the netduino is first powered and then shuts off to let you know that the board has booted . you can turn this led on and off in your netduino app .
you can also power the netduino from your computer ( or usb power supply ) over the microusb port .
netduino mini is designed for industrial temperature ranges ( - 40 to 185f , - 40 to 85c ) .
this version of the adds microsd slot which can be used to insert a microsd card . the card can persit data that can be used by the netduino or the netduino can also write data to the card for local storage . we can even stored compiled programs on the card which can then be executed by the netduino .
the netduino mini is an open source electronics platform using the . net micro framework . it features a 32 - bit microcontroller ( the same one used in the netduino ) and has a rich development environment . the netduino mini has a total of 16 gpios with spi , i2c , uart , 4 pwms , and 4 adc channels .
we are going to looks at netduino plus 2 in depth and also use the same for our examples here today . below is a quick diagram of the netduino plus 2 board with some marking about the ports and pins .
the other led which is blue is user led and can be controlled from the program running on the netduino .
not the answer you ' re looking for ? browse other questions tagged hardware netduino or ask your own question .
by default , the microusb connection is used to deploy apps to your netduino and to interactively debug those apps .
netduino plus 2 is an open source electronics platform based on the original netduino platform . it uses the . net micro framework , which combines the ease of high - level coding with the raw features of microcontrollers . featuring a 32 - bit microcontroller and a rich development environment , the netduino plus 2 is suitable for engineers and hobbyists alike .
this article takes us through our first steps with netduino programming . the examples are simple and are for absolute beginners .
the netduino is really pretty slick . and it ' s hardware compatible with the majority of the arduino shields out there . and , with a bit of work , you can usually port a fair bit of the arduino code to c # too . the netduino forums are here , and there are several blogs starting to cover netduino projects now too .
first experiences with the new netduino go , and how it relates to . net gadgeteer - pete brown ' s urltoken
the real difference between . net gadgeteer and the netduino go is the way the modules communicate with the main board .
this is the main processor , and it contains the code storage space and ram used by your netduino app . the microcontroller’s pins are wired to the blue pin headers , enabling your netduino app to connect to external components and expansion shields .
here’s a project demonstrating how to connect a light sensor to the web using the netduino plus and the thingspeak web service .

the netduino plus 2 has ethernet cooked in already ! there is a full tcp / ip stack with examples ready to go , and a microsd card slot for storing files netduino plus 2 has four times the speed ( 168mhz ) , six times the code space ( 384kb ) , and twice the available ram ( 100kb + ) of netduino plus 1 . features :
in case you missed the announcement on 4 / 4 , the guys and secret labs , along with other members of the netduino community have come out with a new platform called netduino go . head on over urltoken for the introduction forum post .
enough of the comparison . let ' s take a look at the experience of building a simple netduino go demo application .
one of the major selling points of the netduino platform is the robust software framework that netduino employs . arduino uses the wiring language , and the arduino ide allows for a high level of control and visibility over the “bare metal” of the microcontroller . netduino on the other hand , uses the familiar . net framework , allowing programmers to work in c # using microsoft visual studio .
as we already know netduino apps are written using c # language and many of us are already familiar with the famouse visual studio ide for development from microsoft . the same visual studio ide can be used to create , run and debug the netduino apps .
a few weeks ago i asked about source access and firmware compilation . my aim was to enable netduino ' s hardware watchdog .
to deploy a netduino mini app ( and debug ) , you ' ll use serial communication . here are a few options .
as i mentioned , i didn ' t have an official sdk yet , instead , i created a regular netduino project , changed its framework version to 4 . 2 , and then added a reference to the netduino go libraries sent to me by chris at secret labs . presumably , with the new sdk , the experience will be file - > new - > netduino go application .
the netduino is an open source electronics platform using the . net micro framework . it features a 32 - bit microcontroller and a rich development environment . the netduino combines 20 gpios with spi , i2c , 2 uarts , 4 pwms , and 6 adc channels .
netduino 2 is still the same arduino shield compatible board you know and love , except faster with more code space . powered by an stmicro cortex - m3 microcontroller running at 120mhz , the netduino 2 packs 192kb of code space and 60kb of ram . with built - in hardware peripherals like uart , pwm , i2c , 12 - bit adc and dac , the netduino 2 is ready to interface with whatever you throw at it . that includes arduino r3 - style shields , since netduino 2 adds two gpio over its predecessor .

i am trying to setup my netduino mini , but when i press open port in putty , i get windows blip and nothing happens , no error message . what am i missing ?
don ' t let him get away with it . let ' s make sure anyone who searches for chris walker , netduino or secret labs knows that he is a wrong ' un .
the netduino plus 2 has a ethernet jacka enabling us to connect the unit to the network which could be a local network or the internet . connecting to internet opens up a whole new window of features like reading data from remote servers or posting data from the connected sensors and devices to the internet . this will enable us to build the internet of things using the netduino .
optional : shields and starter kits to do cool things with netduino . existing arduino shields are compatible . a shield is just an add - on card that fits the pins on the board .
i ' m very pleased to announce that the netduino v4 . 2 firmware was officially released this morning ( simultaneously with the . net micro framework 4 . 2 qfe2 pk and sdk ) .
this is the netduino plus ( 1 ) firmware 4 . 2 . 0 . 1 source with cw2 ' s 1 - wire extensions and hardware watchdog . the binaries are available here : urltoken
netduino plus offers 20 gpios combined with spi , i2c , 2 uarts ( 1 rts / cts ) , 4 pwm channels and 6 adc channels . plus microsd storage and ethernet ip networking .
omar , wire the rx of the adapter to pin 11 of the netduino mini . wire the tx of the adapter to pin 12 of the netduino mini . wire the gnd of the adapter to pin 4 of the netduino mini . and if you ' d like , wire the dtr of the adapter to pin 3 of the netduino mini . this adapter converts usb to 3 . 3v ttl signals , not rs232 signals . if you hook it up to the 12v rs232 uart ( pins 1 and 2 ) , that could cause trouble . once you hook up the usb adapter to the ttl uart , open up hyperterminal and press esc . then select option 1 to use the ttl uart for deployment / debug . you ' ll be up and running . chris
i ' ll show off the netduino go , along with the gadgeteer main boards and modules , in my talk at the free online p & p symposium on april 24th . please register .
it ' s hard to really see it from this photo , but the netduino go main board is just a bit than the fez cerebus main board . ghi also has several other gadgeteer main boards and kits ( like the spider and the hydra ) . the cerebus is just the latest offering . the hydra and cerebus are open source hardware and software , as is the netduino go .
hi pete and chris , chris , i just bought your book
getting started with netduino
and am getting ready to purchase a netduino to play with . i was going to get the netduino plus but when i was at amazon i noticed the netduino go and saw pete ' s review which lead me here . in the book the plus sounds like the best one but the go wasn ' t released yet . should i get the plus or the go ? pete , by the way , i have your silverlight 5 book preordered from manning ; i haven ' t checked out the meap but i am really looking forward to getting the printed copy in the mail . it ' s cool to find your blog and see what other cool things you are interested in .
) and i haven ' t been able to get a response from the netduino , thats what the . net mf deploy tool says . i am not sure whats going on there . . .
rx , tx , dtr , and gnd wires to pins 1 , 2 , 3
- on the specs page it said that tx is pin 1 and rx is pin 2 . . . so is it that i should connect the tx of the ftdi adapter to the rx of the netduino mini , and the rx of the ftdi adapter to the tx of the netduino mini ?
worth noting was that i didn ' t need a special driver for the go . instead , i plugged it into my machine , and it was recognized as a netduino . it just worked .
netduino plus 2 is the new netduino plus . it has four times the speed ( 168mhz ) , six times the code space ( 384kb ) , and twice the available ram ( 100kb + ) of netduino plus 1 . they ' ve also given it a whole series of rich new features like four serial ports , six pwm channels and 12 - bit adc . the 6 - pin icsp header has been swapped out for a 10 - pin minijtag header . the goal is to enable developers to compile their own firmware using gcc and debug both native and managed code at the same time .
both arduino and netduino are designed to make the world of microcontroller development more accessible to a general audience of programmers , so the use of software toolsets that are already familiar to many programmers is a big plus . netduino programming works at a higher level of abstraction than that of arduino , allowing for more software development features that will be familiar and comfortable for those transitioning from the world of software .
now select your project properties - > . net micro framework tab - > set the transport to usb . this will deploy the code into the connected netduino and also run it on the board .
i ' ve coded in assembly , c / c + + , and c # for the last good 10 years . i coded in assembly for 8051 , in c / c + + for the 8 - bit avrmega mcu , and now in c # for the netduino . it only make sense that netduino continues to motivate development in c # and not going backward to c / c + + or native code . with this in mind , i recommend that the netduino opensource community should expose a standard c # class which allows read / write to / from the mcu ' s registers directly .
here’s how you can take this project further with a design from shadowlord . you can create a web front - end using html , css , and jquery to visualize your status updates from the netduino .
thanks for this sample . this works for me out of the box when it’s running on my netduino but it seems to get stuck when i try to run it using the debugger in visual studio .
in my opinion , the zif socket is a must - have item because the pins on the netduino mini are fragile and are unlikely to survive being inserted and removed from a breadboard too many times .
the netduino mini may be programmed over its rs232 uart ( pins 1 , 2 ) or its 3 . 3v ttl uart ( pins 11 , 12 ) . by default it uses the rs232 uart .
before we get into actually creating the project , what will it be ? well this is just something simple , nothing useful , but hopefully gives you an idea how to work with the netduino go .
here’s a video of the code in action on my netduino go , i’ll see if i can’t get another video done when i get the third led module in place ( only 2 for now ) .
i just received a bunch of packages from both secret labs and ghi electronics . the secret labs packages contained their brand new netduino go . the ghi package contained the fez cerebus starter kit i ordered .
the netduino go modules have their mounting holes on 5mm centers , just like the gadgeteer . so , i was able to use a tamiya 70172 universal plate ( large ) as a home for everything .
i really wanted to write more complex examples and explain them but its already late sunday evening . but i will leave you all to do you experiments with the netduino and promise to add more examples soon .
this is the small golden dot at the end of digital i / o pin headers . this is used to erase the netduino completely and to start over from scratch . this was made in order make this board hacker friendly so the netduino can be repurposed as an arm microcontroller development board . the erase function is activated by connecting a wire between the 3 . 3v pin and the erase pad for a few seconds .
had an interesting email today from someone who claims to have purchased the ip of secret labs ( what ip ? ) and also the netduino brand . he claims that his company established wilderness labs to rescue netduino and that chris walker has nothing to do with the business . the email alleges that they were going to make an announcement next month but weirdly their suppliers know about my website and it is harming their business .
3rd - party accessories offer pre - built functionality like gps location , servo control and battery power . netduino is also pin - compatible with arduino shields . 3rd - party drivers are required for some arduino shields .
hi chris , i got this today ( urltoken ) and i haven ' t been able to get a response from the netduino , thats what the . net mf deploy tool says . i am not sure whats going on there . . .
rx , tx , dtr , and gnd wires to pins 1 , 2 , 3
- on the specs page it said that tx is pin 1 and rx is pin 2 . . . so is it that i should connect the tx of the ftdi adapter to the rx of the netduino mini , and the rx of the ftdi adapter to the tx of the netduino mini ?
the netduino supports existing arduino - style shields just as it always has , but just as you had to before , you ' ll need to write ( or find code for ) drivers to make those work .
the netduino plus is an open source electronics platform using the . net micro framework . the board features a 32 - bit microcontroller and a rich development environment , making it a perfect solution for engineers and hobbyists alike .
article was very timely . i had ordered my netduino for play 15 minuts before checking on this blog post ! i will definitely use scott ' s code as something else to play with until i get some components !
netduino combines 20 gpios with spi , i2c , 2 uarts ( 1 rts / cts ) , 4 pwm and 6 adc channels . best of all with netmf 4 . 1 , you can use visual studio 2010 !
the specs & schematics of the netduino mini give us all the details required to make the connections and the forums have a decent how - to but i wanted to make the process postcard - accessible and more visual .
secret labs engineers and manufactures electronics platforms for software developers . our open - source netduino product line ( launched in 2010 ) is used by 10 , 000s of software developers worldwide as the basis for their custom electronics projects .
netduino and arduino both provide great introductions to microcontroller development for those looking to transition from software programming . at a high level , netduino can be a more approachable platform for casual experimentation , particularly if you have a background with the software , c # , . net , or visual studio . arduino provides a slightly steeper learning curve with its ide but has a bigger community for support and more flexibility should you want to take a prototype into production .
and its very expandable just like the arduino ! 3rd - party accessories offer pre - built functionality like gps location , servo control and battery power . netduino is also pin - compatible with arduino shields . 3rd - party drivers are required for some arduino shields . design files included . netduino is an open source electronics platform . all design files and source code are included . learn from the designs . remix , and enjoy the freedom of open source .
these 3d printable baseboards have mounting holes for a netduino plus space for a half - size breadboard . you may find it helpful to ream the holes with a 3 . 2mm ( 1 / 8” ) drill bit after printing .
the netduino mini can accept 5v ttl signals . it sends 3 . 3v signals . . . some but not all 5v ttl cables will understand these signals . so we recommend 3 . 3v cables , but technically 5v may work .
the netduino go starter kit is a plug and play component set with arduino shield compatibility targeted towards education , but also popular with engineers and hobbyists . this starter pack comes with all the necessary parts to hit the ground running with netduino go . included is the go mainboard , the shield base , a button module , a potentiometer module , an rgb led module , 4 go cables , and a 3 ' microusb cable to connect to a computer for programming and power .
netduino is an electronics platform which software and electrical engineers can use to prototype new electronics products . it is also used extensively in education and for personal projects . netduino is assembled in the usa , uses premium components , and is designed for limited commercial / industrial use in addition to personal use . using c # it offers a rich feature set and a world - class microsoft ide which debugs via usb . many customers embed netduinos inside their products ( versus competing offerings ) .
the netduino requires voltage from 7 . 5v to 12v with the plug having a center positive pole . the power can be supplied using a ac - to - dc adapter with 5 . 5mm by 2 . 1mm outer / inner plug .
hi test123 , welcome to the netduino community . it could be that you don ' t use the correct bitrate . what settings do you use at this moment ? if i ' m not misstaken , the default bitrate should be 115200 .
hi , i have been trying to debug the code from visual studio 2010 and using it to deploy to a netduino plus 2 , however i am getting deployment errors that does not go away even after power cycles and resetting the dev board .
long - term , i would expect the netduino go to also have a very rich ecosystem of modules . plus , the potential of those individual modules is , in my opinion , greater , as the reall processing all happens on - module .
to get a glimpse of how its done , check out the basic ' getting started ' guide you can even now use the netduino on linux & mac computer using open source mono instead of . net and its very expandable just like the arduino !
ordered the netduino 2 and got a 2 plus ! very happy about the free upgrade . i love the fact that i can develop in c # rather than c / c + + . much more civilized language . great alternative to an arduino .
the netduino family is based on the cortex - m micro processor running the . net micro framework ( netmf ) v4 . 3 . development can be done on both windows , with visual studio , or with xamarin studio on mac os x . netduino is packed with io ; including 22 general purpose input / output ( gpio ) ports , 6 of which support hardware pulse width modulation ( pwm ) generation , 4 uarts ( serial communication ) , i2c , and spi ( serial peripheral interface bus ) .
surprisingly , i believe it’s correct . the schematic shows that it uses the enc28j60 ethernet controller [ datasheet ] which is 10base - t . the original netduino plus used a different controller ( the dm9161aep [ datasheet ] ) which supported 10 / 100 mbps .
christmas has come early ! now to come up with some bsod test cases thanks chris , and great work getting these netduino updates out for us right along side of the long awaited release of . net mf 4 . 2 rtm ( qfe2 ) . kudos ! steve
this post is how to quickly get up and running with your netduino go , based on chris walker’s getting started forum post , with some enhancements that i think will make it easier to get up and running , as chris’ post unfortunately leaves a few things out .
@ simon he ' s either really stupid for buying the netduino ip ( and all of cw ' s problems ) or he ' s got one heck of a legal shield from the nightmare . . . it ' ll be interesting to see how this plays out
input ! output ! interface with switches , sensors , leds , serial devices , and more . netduino offers 22 gpios combined with spi , i2c , 2 uarts ( 1 rts / cts ) , 4 pwm channels and 6 adc channels . code ! debug ! repeat !
once you have all this together you need to be able to deploy the code to your netduino . deploying the code is easy , simply hit f5 in visual studio and that should send it off to your device . from there you can see how well it works .
the netduino plus 2 has four times the speed ( 168mhz ) , six times the code space ( 384kb ) , and twice the available ram ( 100kb + ) of netduino plus 1 . they’ve also given it a whole series of rich new features like four serial ports , six pwm channels and 12 - bit adc . the 6 - pin icsp header has been swapped out for a 10 - pin minijtag header . the goal is to enable developers to compile their own firmware using gcc and debug both native and managed code at the same time .
the netduino may be powered by an ac - to - dc power adapter with a standard 5 . 5mm ( outer ) / 2 . 1mm ( inner ) plug . allowable voltages are from 7 . 5v to 12v , and the plug polarity must be center pole positive .
the hardware came in a number of classic netduino blue boxes , with each board and module inside packaged in quality esd - proof bags . secret labs has always had a good unboxing experience . i ' ve also really like these bags as they just seem to be quality .
i previously had installed the . net microframework 4 . 2 sdk , so i didn ' t have to mess around with that . i won ' t cover much of installation here , as the full netduino go sdk wasn ' t yet ready when i got the hardware .
the book chris walker wrote about
getting started with netduino
is still available on amazon as someone recently pointed out . i know that it ' s old and not likely to get much attention anymore but i posted a bunch of comments in the reviews stating the following :
now i just have the netduino for now , so i haven ' t got any attachments . if i was a hardware guy , i ' m sure i ' d go try to take apart a toaster or remote control and declare something like
this toaster just needs a one ohm resister on pin - out 5a so i can invert the voltage and it ' ll toast bread over bluetooth
but i have no idea what that means . all i can do with the netduino out of the box to flash its led , as pete points out :
this would allow c # programmer to create their own driver in c # and not have to deal with any native c / c + + code . i think this feature will make netduino unique compare to other products out there . i strongly suggest that this feature gets implemented .
plug the rgb led into any socket on the main board . ( netduino go doesn ' t require you to match socket ids or letters or anything ) . i used socket 8 in the example here . if you choose a different socket , just indicate that in the code .
before the go was introduces , i was looking at creating a number of modules for the . net gadgeteer ( i still am ) . in each case , those modules requires an on - module processor to handle things like multiplexing many inputs , handling some logic specific to the board , or something else . the on - module processor approach is actually one of the best ways to scale out a solution whether you ' re using the netduino or the . net gadgeteer . the netduino go approach simply formalized it and provides tested code you can use to get started .
if you use a mac or a linux computer , the mono project provides an alternative set of . net programming tools . while the examples in this book use microsoft’s visual studio express tools , appendix b explains how you can program a netduino using mono on a mac or linux computer .
arduino became so popular that it spawned a number of projects that have taken its open - source form factor and extended the functionality . one such project is netduino , a microcontroller platform that is pin - compatible with many arduino shields , but it is based on the . net micro framework .
in this picture , note how the netduino has blue leds lit next to each active socket . this helps you visually confirm which socket your drivers are using . the tiny blue leds aren ' t as bright as they appear in this photo , that ' s just my camera being annoying .
if you already know about arduino then the answer to this question is quite simple . it’s an arduino programmable in . net . otherwise , netduino is a prototyping platform based on the . net micro framework . it uses a 32 - bit arm microcontroller and compatible with most of the arduino shields .
clint sent me a
netduino
board today . it ' s similar to an arduino board , except it uses the . net micro framework . micro you say ? that ' s techie - speak for
tiny ass framework .
i spoke to colin miller about this earlier in the year on video at channel 9 .
the netduino currently has provision only for usb power ( although i understand there may be an adapter coming ) , provided directly on the main board . the gadgeteer always has the power provided by a separate module , always colored red . the source of that power can be an adapter , usb , batteries , or something else .
even though there is lots of example code for neopixels for avr , propeller and pic chips , it ' s a bit of challenge getting these leds to work with the netduino . with the default firmware of the netduino ( any variation , plus or no ) , it is not possible to send data to neopixels . the reason is due to the special high - timing - specific nature of the data sent to the pixels . neopixels , or ws2812 / ws2811 , use a single wire protocol that encodes bits as pulses , the time width of the pulses determine whether each bit is a binary 1 or 0 . the following is a screenshot from the ws2812 datasheet .
