#16627 How to Connect Two netduino's and transmit data's

Thanks for your response.....But I am planning to establish a communication between two Netduino's ...If i got it working then it will be easier to connect more servos....I’ll take a crack at it. There are four ports to control servos, so you don’t really have to use two Netduinos unless you just want to. Here someone has a single Netduino set up with four (pins 5,6, 9 and 10). It is a little difficult seeing where the wires go from the video, but if you’ve already successfully got one working, you should be fine. Also, note the Netduino can’t supply the servos enough power if they’re under any kind of load. (Warning: It could screw up your Netduino) Here another avid user has found a board to control eight with one Netduino. Hopefully, Stefan will reply… he’ll know how to power them from a separate power supply to keep your Netduino healthy if the little board doesn’t do it already.
Once again thanks

#18395 Communication between Two Netduino's

The Netduino microcontroller supports only Master mode, so you'd need to implement I2C slave in software (i.e. write native C/C++ driver, due to precise timing requirements that cannot be achieved in managed code).
At the moment, the only interface available to connect two Netduinos is SerialPort (SPI slave is not supported in the current version of .NET Micro Framework).
Hi CW2
Thanks for the reply..... I am a new to programming world.... Can you please give a outline of what to do to implement I2C slave in software...

#18402 Master/Slave Connection with Netduino's?
Posted by karthick on 25 September 2011 - 04:02 PM in General Discussion
Hi MarioI don't think Netduino/MF supports the I2C slave mode.
The most simple, yet reliable way to exchange data between two (or more) Netduinos are using the UART. Until you don't use the RS232, you may wire the two boards without any additional hardware.
Supposing to use the COM1 on both the Netduinos, wire the I/O #0 of the first board to the I/O #1 of the second one. The other wire is the complementary.
Cheers
Thanks for the valuable information... i will Try this and hope i get through this problem....
#18423 Communication between Two Netduino's

It's one of the things where, if you don't know how to approach it, you probably don't want to be doing it (because it'll cost you too much time). It's not inside the "normal" use case of a netduino - you'd need to take the source of the firmware, add the required functionality there, compile it and overwrite the firmware on your netduino with your custom one.
hi stefan,
I left I2C and now trying trying to connect 2 netduino to one netduino using RS232 as it has two serial port pins.....Anyway thanks for your reply.....
