Tty for serial port to Arduino from Linino

Hardware Arduino Yún

I got Firmata to work between a Python script running on Linino and the Arduino. I was able to get about 400 messages per second which is sufficient for my needs. I made the following changes to the StandardFirmata sketch "begin" section.

void setup() 
{
  
  Firmata.setFirmwareVersion(FIRMATA_MAJOR_VERSION, FIRMATA_MINOR_VERSION);

  Firmata.attach(ANALOG_MESSAGE, analogWriteCallback);
  Firmata.attach(DIGITAL_MESSAGE, digitalWriteCallback);
  Firmata.attach(REPORT_ANALOG, reportAnalogCallback);
  Firmata.attach(REPORT_DIGITAL, reportDigitalCallback);
  Firmata.attach(SET_PIN_MODE, setPinModeCallback);
  Firmata.attach(START_SYSEX, sysexCallback);
  Firmata.attach(SYSTEM_RESET, systemResetCallback);

  Serial1.begin(9600); // Set the baud.
  Firmata.begin(Serial1);
  systemResetCallback();  // reset to default config
}

On the python I installed PyFirmata and pyserial. The following code turns on the LED:

from pyfirmata import Arduino, util
board = Arduino('/dev/ttyATH0', baudrate=9600)
board.digital[13].write(1)
