Have to use SerialUSB on M0 to print to Serial Monitor, but variant.h says otherwise

[evgenykochetkov]

Here is the relevant part of variant.h:

ArduinoCore-samd/variants/arduino_mzero/variant.h

Line 203 in bab730b

#define SERIAL_PORT_MONITOR Serial

Am I doing something wrong?

Hi @evgenykochetkov ,
that define in fact only makes sense for M0 Pro, which exposes both Serial and SerialUSB on USB connectors. Since M0 and M0 Pro share the same variant, either one is wrong. @cmaglie should we change it into SerialUSB?

Oh, I totally missed the fact that they share the same variant. Thanks for the explanation!
