Couldn't get my firmware to work, rewriting it like yours and adding the adafruit library helped me fix my macropad. Very useful info, thanks for sharing it. 👍

Thank you. Now library from the Adafruit is updated and called Adafruit_Keypad.h. But you can figure it out without any problems using example files.
