How do I access UART 0 from an arduino sketch to communicate with a shield plugged into the Galileo? I am trying to communicate with an XBee radio on an Arduino wireless proto shield that wants to communicate via pins RXD and TXD of the arduino shield socket.
Serial.print() commands which would normally send data to these pins only sends data to the host computer as far as I can tell. I have a scope on the pins. Any help is greatly appreciated.
