I'm using a SODAQ N211 shield on a crowduino mcu board. For an application I need an extra serial port. I've tested two options:
- Including the Arduino SoftwareSerial library doesn't (isn't supported on a M0)
- defining "serial2" also doens't work despite the fact that the SAMD has 6 SERCOM devices.
Any suggestions for how to create the extra serial port?
