Hi!
Does there exist a software serial library that works on microcontrollers without PCINT? The ATmega64 and ATmega128 have 8 "general" interrupt pins, but no PCINT.

My Yet Another Software Serial (written for an Uno) uses the external interrupts. Maybe it could be adapted to meet your requirement.

Two or three hours spent thinking and reading documentation solves most programming problems.

Or change to a compatible device that does have PCINTs, like the Atmega1281 or 2561.

No, that's not an option. The ATmega64/128 are much cheaper, and should fit most applications where 4kb of RAM
