content: Hi,Im trying to make a simple modular device one master board and couple of slaves. Im currently stuck at the interface which would be used to communicate between master and slaves - i need two way communication. All modules will be connected in parallel using only two wires.I though about using I2C SRAM buffer on every module so the master can read data from this memory, but i cant find any memory that supports more than 4 addresses - does any one know and module which i2c address can be choose by the user? I could implement this memory on a microcontroller acting as an i2c slave but this solution has one problem - i need two i2c interfaces one for the master and one for the slave.Does any one know any way to connect master to couple of slave using only two wires and a data buffer?

content: You could use SPI and create a shift register cascade on the boards so you can select each one by stepping through the shift register to active each boards chip select.

content: Quote from: DanioIO on November 11, 2014, 10:35:38 pmCANbus? It's widely used in automotive, some microcontroller families have it as an option.Hereis a decent intro to CAN.(I'm ignoring the RAM/buffer part of what you said, because I have no idea if that's necessary or just something you made up on the spot to help solve the problem. CAN does have "remote frames" though, which can do something similar.)Or along the same lines, maybe LIN, which I don't really know much about.It would help if you told us a bit more, like distances involved, data rates, hobby or industry, and that sort of thing.

Dead simple to build and based on easily sourced and inexpensive parts. You can also choose to built it as a +/-15V supply with minor component changes.''connecting 2 wires from the wallart's positive to each psu positive and 2 wires from wallart's negative to each psu negative is it correct? i'm having some troubles there and i'm not totally sure.thanks in advance!

content: You said 12VAC, so there's no positive or negative.Connecting power supplies in parallel is generally not recommended, because it can cause issues with one power supply trying to inject power into the other. If they are two identical wall warts with an AC output, it should be possible to connect them in parallel, but they must be in phase, otherwise it will result in smoke. Connect one side together and measure the voltage between the other connections. It should read close to zero. If it's double the voltage, then reverse the connections to one of them and try again. Once the voltage is close to zero, the other sides can be connected together.What exactly are you powering? Please post some schematics and/or provide links to datasheets and/or the place where you bought the equipment from.

Connection of relay, inverter, charger and battery - Page 1

content: Hello. I am trying to build a system that allows a 12V battery to be charged automatically when there is power in the house and when there is no power, an inverter connected to the battery is also activated. For this I use a relay. The symbology of my relay is the following: 1 coil contact, 2 coil contact, 3 input, 4 normally closed contact and 5 normally open contact.I made the following connection using the connector numbers mentioned above: connector number 3 of the relay I connected to the positive of the battery, connector number 4 I connected to the positive of the inverter, connector number 5 I connected to the positive of the charger, connector number 1 I connected to the positive of the charger, connector number 2 I connected to the negative of the charger. The negative of both the charger and the inverter were connected directly to the battery. When the charger is off, the inverter stays on, when the charger is on, the inverter turns off and the battery begins to charge correctly. Up to that point everything is fine, but if I turn off the charger again, the inverter does not turn on. Why is that?

content: You really have to provide some kind of schematic or diagram. I tried to follow your numbering, etc and its not clear what you mean. One thing that I noticed is that you didn't mention the relay common terminal. This is the thing that connects to either NC (relay coil off) or NO (coil on). It sounds like you might be only using NO and NC. Draw a picture of some kind, you can hand draw it and take a pic with your phone. For best answers, take a minute to look up the symbols for the devices. You can use just a box for the inverter and charger, just label their inputs and outputs.

An ESP32 device would be one of them, however, I would like to be able to connect to this device from outside the home.However, I would like only me and the other person (only two of us) to have access to this device from the outside, and in practice this means that only two particular smartphones would really be able to connect to this device if we were away from home and home network. Any other device should be rejected immediately if it tries to connect to our ESP32.Is there any possible solution that would not introduce additional financial costs?

content: You need to set up a VPN (Virtual Private Network) connection into your LAN.This way you can install a free open source VPN client on your phone that routes all of the phones internet traffic trough a VPN tunnel. The other end of the tunnel connects to a VPN server on your LAN. This server is listening for outside connections on WAN, authenticates with a key, then opens up the other end of the tunnel, letting the traffic from the VPN client spill out into the LAN.This way you can connect to it from anywhere on the internet and your phone will look like it is connected to your own LAN directly over WiFi.If you have a good feature rich router in your LAN then in a lot of cases the VPN server can run inside the router with 0 extra hardware required. Otherwise you can use a Raspberry Pi to serve as a VPN server.More feature rich routers also support scripting, so in that case you could also do it without a VPN. Just make a script in the router that listens for a key on a certain WAN port, once it sees the key it starts forwarding traffic to the ESP for X minutes.

content: Use BLYNK 2 app. For using BLYNK, your ESP8266 should be connected to a wifi network. But with this app, you can monitor and control your ESP8266 from wherever you are. You can switch any load connected to it. You can also read any sensor data connected to the ESP8266. Yeah, initially at the time of pairing the ESP to the mobile phone( where the BLYNK app is installed), they must be close to each other. But after that, you can control you ESP with your mobile phone from anywhere in the world. There is a free version of BLYNK 2.

content: I imagine the unit you intend to wire is some kind of controlled load to discharge a battery.Many current measurement sensors will work only on the low side (as the shown diagram) and possibly fail when connected to an higher potential, others are only high side, and some are happy both ways.So, not knowing its make/model or the schematic, it's very difficult to answer your question.Moreover, the "thin black line" looks like it should be the GND for powering the unit, why is it not connected?If it's internally connected to I-, definitely what you are asking for is not possible.

content: Quote from: Srivatsa R Upadhya on August 13, 2021, 12:21:55 pmIf you connect the shunt resistor to the high side before the load (on the red wire) then you will need to use a separate, galvanically isolated power supply such as a separate battery to power the panel meter. The I+ terminal should go to the electric vehicle battery (+) and the I- terminal should go to the load (+). Do not connect V+ terminal. This configuration will ONLY measure current, but not voltage because the I- terminal will be above GND. You will need another panel ONLY for measuring voltage with this configuration.If you want to measure voltage and current with the same panel meter then connect the panel meter as per the original wiring with the shunt resistor after the load (on the black wire).

Port 6 of KSZ9567 is RGMII between KSZ9567 and LAN8840.So, I want to know how to connect the Tx and Rx of the devices in this interface.Since, for RGMII, there's no concept of MAC and PHY, since RGMII is Source synchronous interface, I am confused.I checked in the HW Checklists of both the device. Links: KSZ9567(https://ww1.microchip.com/downloads/aemDocuments/documents/UNG/ProductDocuments/DesignChecklist/KSZ989x-KSZ956x-KSZ9477-Hardware-Design-Checklist-00004151.pdf) and LAN8840 (https://ww1.microchip.com/downloads/aemDocuments/documents/UNG/ProductDocuments/DesignChecklist/LAN8840-HW-Design-Checklist-DS00004680.pdf).On the figure on Page 10 of the LAN8840 checklist, the connections between the LAN8840 PHY and MAC device is Tx to Tx and Rx to Rx.Whereas, on page 19, Figure 8.4 on the KSZ9567 checklist, the connections between the KSZ9567 and LAN8840 (PHY pin definition - I took this figure because LAN8840 is a PHY), is Tx to Rx.Both seem to conflict. Can someone tell me which is the correct method of wiring the Tx and Rx between the devices?Going through this Eval board's RGMII interface - KSZ9477 (https://ww1.microchip.com/downloads/aemDocuments/documents/OTH/ProductDocuments/BoardDesignFiles/EVB-KSZ9477EvaluationBoardSchematics.PDF), It is wired Tx to Tx and Rx to Rx.Also, When you see the pin buffer type of RX pins of both the devices, they seem to indicate that Rx pins are output pins and have output buffers in both the devices.So, shouldn't it be Tx to Rx connections between the LAN8840 and the KSZ9567 devices?Totally confused. Can someone clarify?

I don't think it can handle a lot of insertion force...Extra info: I will settle for a PCB mounted connector but I would prefer one that can be extended with wires (flat cable or other).By the looks of it other touch displays come with the same flat flex strip and would require similar connectors. I hope some of you know what I need.Thanx.MarcIn addition any tips and tricks you can provide for working with a resistive touch screen would be most welcome. It will be used as a touch pad without a display mounted on a guitar's scratch plate (strat-type). I was planning on feeding it into a small AVR MCU to output MIDI control messages.

I found one on Ebay (NOS) and bought it. Be warned, though, that since these are used on microphones (both ham and professional), the audiophiles create a demand which runs the prices up. I also found several people making cables with the other end being an XLR connector. Hope this helps.Gold plated pins were never an option. The contacts seem to be somewhat of a tuning fork with high pressure. I would not expect a problem.

Hopefully someone who knows better will give some more specific advice.

Without carefully matching the jack type, you may have inadvertently disabled plug insertion detection.With that said, it's usually enough to exactly match a jack with the same number of pins and bridges between them.Do you have any pictures of the original jack?

content: It probably needs a connector with a normally-closed contact in the 2nd ring.You can see how each side has a trace. One of them is the detection.When you insert the jack, the contact opens.

content: D6 is a name of the component, the pad that came off looks like no contact -- hence the reason it came off.But really, make some better pics. Don't just photo your screen, take pictures with your microscope camera from both sides and post them here.Also. Take old connector and new one, and measure things. Stick male part of connector into it and see if it all checks out just like on old one. You gotta make sure it matches. Can't help it using pics online here. Physically remove the new one, compare it to the old one, use continuing mode to check that all contacts are same as on old one.Post the board in better quality from both sides.P.S. This looks interesting, but I can't tell what it is from your photos

content: I'm not sure your photo is clear enough to give a concrete answer; but yes, there is something other than "six wire".Key parts to identifying a connector would be the end-on shape of both the housing, and the individual pin shrouds (take a clear photo straight on of the very end) and thepitchwhich is the distance between pins. Again, it's not completely clear, but that looks about the scale of a Molex Mini-fit, or 4.2mm pitch, but I'm sure it's not a mini-fit.

content: What zanfar said: we cannot possibly begin to identify it based on the uselessly blurry photos (and lack of other info) provided. There are literally thousands of connector series out there, and many of them look extremely similar, especially without any scale. (Some essentially are scaled up/down versions of others, so without scale, theyarethe same!) You need to providesharp, well lit photos from every side, and either a carefully placed ruler in the photos, or provide accurate measurements. Also, give us context of what the connector is used in: someone might already know what it is.Just to be clear, though, pin pitch is NOT the distancebetweenpins, it’s the distance between pincenters.

But JST might be more versatile? i need to get the tools for which ever i choose.

content: One thing is bothering me ever since I started playing with electronics and microcontrollers, figuring out how to read cable pinouts. For example I have a connector in some device and want to design a matching one on a PCB to connect them with a ribbon cable, but I always have trouble figuring out which pin is which and from which side to look not to make a mirrored connector. Pinout descriptions sometimes include a note what way to look at the connector so you will see the same pin order as it's drawn in documentation, but not always. This is specifically a problem with two row connectors like IDC and they're everywhere.Any good advice on how to deal with this in a simple way? I'm really tired of wasting time figuring this out every time I draw a schematic or try to connect something to a breakout board or a breadboard using jumper wires.

Without telling what board you have, nobody will know to answer your questions.First thing will be to read the manual for your board, there might be specified the type of supported cameras, maybe the type of the MIPI connector, too.

I think there is a BOM list with all the parts, including the exact model of the connector. There was a demo/lab/workshop lesson using an 8MP camera: this is the thread w link to BOMReply #60Most probably this is the connector type (from the BOM):MJS-3062-HRS 0.4mm Pitch, 1.5 Height, Board-to-Board Connectors.(DF40C-30DS-0.4V) 1 HIROSE DF40C-30DS-0.4V(**)I'm writing this from a vintage PC that is working very, very slow, so I can not dig for more details right now. Have the same DECA board and a few MIPI cameras from former mobile phones, and none of them have a matching connector.Try searching for MIPI CSI 2x15 pins camera, or for DECA MAX10 camera. If you find any, please post in the thread I linked, so others with the same DECA board would know about the camera you found.

They sense in the negative lead which can be an issue in some circuits with common grounds. Only one of the positive leads needs to be connected. There have been several technical tear downs of these units here with test reports. I think everyone should own one of these.

I would like to encapsulate some electronics and don't want to solder wires to boards.Can You advice me some? No high - current, I want to use cabling with cross-section up to 0,5 mm2, of course if connector allowes more then it is advantage. Voltages up to 120V DC. More features - SMT soldering, rather less than 3 mm height - I plan thin layer of encapulation.Almost every connector fits above requirements but couldn't find one for potting.

GenRad did use different suppliers through the years. The P3/P4 used Rochelle salts as the element. The P5/P6 utilizes lead zirconate-titanate for the piezoelectric element.The second 1551-C (newer, light gray paint) I have has a type 1971-9605 microphone. This replaced the P5/P6. It is also a ceramic element.I have a P6 that pairs with a 1564 Sound and Vibration analyzer.
