I found a serial bit bang program using direct port manipulation which won't compile - code attached below. It complains that PORTB is undeclared. I created a new sketch and included the softUart.h at the top. I also found a version of 'blink' using direct port manipulation which compiles just fine…

error 'PORTB' undeclared

Sorry, didn't see that :-/

Try to put "#include <Arduino.h>" as the first line in "softUart.h"
