I'm trying to use the Serial communication on pins D0 and D1 but I cannot get any signal over there using SerialUSB.
Is this serial port in parallel with the Serial on USB or it has a different name?
Thank you in advance.
Hi, please look under D21G board specifics at https://github.com/Industruino/libraries
D0/D1 is 'Serial'
If you are using the PROTO, you can go ahead.
If you are using the INDIO, D0/D1 is connected to the RS485 port by default. If you want to use it for other purposes (from the IDC expansion port) you have to change the hardware switch on the baseboard (to upper position, away from the RS485 port).
