content: Hey Guys,I just saw on the STM website the new development board. It comes with the STM32F429ZI. (http://www.st.com/web/catalog/tools/FM116/SC959/SS1532/PF259090)The STM32F429ZI features 2 MB of flash memory, 256 KB of RAM and runs with 180 MHz.Also interesting is that the board comes with an 2,4" Touch Display.The board is listed on Farnell for £16.http://uk.farnell.com/stmicroelectronics/stm32f429i-disco/stm32f4-discovery-eval-board/dp/2355377?Ntt=STM32F429I-DISCO

content: It doesn't seem to actually be in stock anywhere. And It's $45+.I'll keep my Arduinos, TYVM...(OTOH, I think all those people buying $30 Arduinos and adding $70 AMLCD shields to them have always had rather questionable judgement...)

content: I can see them fine on the AU element14 site @ about $34AUD (our currency has fallen quite a bit of late...) But if I go to the US site they show no stock and 40 something dollars...These have just been released, I've been waiting for them to come out, so I'd say farnell just needs to update their US site. If anyone in the US wanted to order from them I'm sure you could send them an email and get them to fix it.

content: The digikey US site says $42 and 18 in stock.I could swear it said $47 and no stock before I made my post...

content: Quote from: westfw on October 08, 2013, 11:30:25 pmYeah they're constantly changing at the moment, farnell has been a different number (went from 18 to 750 available). When I looked at digikey they were zero also.But that's too high a price. If I can buy one for $34AUD, the US should see them at about $30 just on the exchange rate, let alone buying in Oz from farnell normally attracts an inflated price.

content: Damn it. I just ordered and received a cheap F407 discovery board after not being able to find a similar priced one with LCD interface

content: Speaking of the STM32F4: Does anybody know of a somewhat free/gratis development environment, which would make these boards useful for hobby use, please?Am really interested in the 'F427 board, but it is kind of a let down if you can only use 32KB code size on a chip this large.I'm aware it seems possible to 'roll your own' on Linux, but I was hoping for something closer to a turn key solution.

content: hmmm I've been asked to fill out one of those "security" forms for this boardAt first I thought it was due to the "crypto/hash processor" but that's only on the 439. Is there something else about the 429 that places it in this category or have the bureaucrats just lumped them together?

content: Quote from: dannyf on October 10, 2013, 12:48:17 amThere appear to be roughly 28 I/O pins left over, once the on-board peripherals have had their fill.Quote from: gmb42 on October 10, 2013, 11:21:39 amThanks! Seems my Google fu needs a tune-up.

content: Quote from: ElectroIrradiator on October 10, 2013, 11:36:57 amOne of the good things about the old F4 board was although maybe a dozen pins were connected to peripheral, they were all still brought out to the headers. So it is a trivial job with hot air to pull any of the extra chips your not using and will interfere with what you're doing. Hopefully they've done the same thing with this board.

content: Quote from: Harvs on October 10, 2013, 11:53:29 amSeems they have retained this feature. There are a total of 128 pins on the headers, and only 12 are not used for dedicated I/O pins. I am actually curious about the low number of ground pins brought out on the headers, but that is a discussion for another time.Note the LCD is hardwired to use 3x6 bit color, so that may be a bit of a limitation for some applications.
