Serial output from the firmware.
Create a blinky LED with RobotDyn’s M0-Mini board which is compatible with Arduino firmware.
For serial printing, SerialUSB.println() should be used instead of Serial.println() because SerialUSB uses the Native Port, which is an emulated serial port (USB-CDC).
The following code should be used for initialising the serial so that the print statements can be viewed in the setup():
SerialUSB.begin(9600);
while (!SerialUSB) { }
