Cannot get digitalWrite fast with ATTinyCore

Other Hardware 3rd Party Boards
3

@JohnRob is likely referring to GitHub - NicksonYap/digitalWriteFast: Arduino library for faster digitalWrite using port manipulation and macro for ease in pin assignments.

The doc states

Compatibility

  • Arduino Due
  • Arduino Zero
  • Arduino Mega
  • Arduino with ATmega644 or Atmega644P chip
  • Arduino Leonardo
  • Arduino Uno (I have only tested with uno)

If not in the list, the macro will revert back to digitalWrite(), pinMode() or digitalRead()

Maybe doc like this can help
