We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I am trying to look for some documentation about using Arduino Library and I2C communication. I have a Master arduino connected via usb cable receiving instructions from processing code. And the Slave arduino would be connected to the Master arduino by the SDA and SCL pins. In arduino environment I can make it work with the Wire library and Wire.methods()... But despite the fact arduino library have got a arduino.I2C constant, I am not sure if it have a method to talk to Firmata in order to use the I2C protocol...
Does anyone know something about this?
Thanks in advance,
