Hi alanalg,
Have you find a solution yet?Huiyugan
You can connected the 3V3, TX, RX and GND to Galileo and the following code for example:
void setup() {
Serial1.begin(9600); //Compare with arduino uno. Galileo use "Serial1" instead.
}
//So the following code just like:
void loop() {
Serial1.println("Hello World!");
}
