grandsmarquis / firmatac Goto Github PK

I want to read A0 on my board, I'm not entirely sure how this works, and there's no example so was trying to write one. So far I have something like this:

firmata = firmata_new("/dev/ttyACM3");
firmata_pinMode(firmata, 14, MODE_ANALOG);
while(1) {
  firmata_pull(firmata);
  printf("read value: %d\n", firmata->pins[14].analog_channel);
}

Is 14 A0? or is it 0? And I'm guessing that doing the pull means I update the data available in t_firmata which is what I want but do I need the pinMode call and do I need to do someting else first like register for ADC updates/ask for it? Can I ask for just A0?

Similarly have you got any examples of how someone would do some i2c or spi?

Hello!

I have included the library to my C++ project. When I try to run the example LED_Blink code, LED connected to pin 13 of my arduino Mega blinks in some pattern and returns the firmata version 2.3 which is currently running on my arduino board. I aslo get the command line prints saying the digital value of 1 has been written. But the LED does not turn on at all. Turning off LED also behaves the same way.

I used the firmata test program on my windows machine to check if the standard firmata works or not. It works perfectly well with the test program. Current version of firmata is 2.3.8.

If the firmware version is being returned correctly, why is the Digital write not working? Is there anything I'm missing here?

Appreciate your help. Thanks in advance..
