itsy bitsy 32u4 SoftwareSerial ?

Does anyone know if the itsy bitsy 32u4 (5V) support SoftwareSerial ports ?
If so, which pins can be used ?

The standard softwareserial library supports the atmega168 / atmega328, but. not the 32u4.

You could use hardware serial on the RX/TX pins of the 32u4 as there is an extra hardware UART on pin 0 and 1.

With Arduino, the ATmega32u4 hardware serial port on pins 0 and 1 are addressed as Serial1, e.g.

Code: Select all | TOGGLE FULL SIZE
Serial1.begin(115200);

Works MUCH better than SoftwareSerial!
