    Quick tip, you can use a multimeter to identify the pins. Just check for conteniuty between teach two pins and press the buttons until something beeps.

    "Borrowed" the entire code, tested this code against other ones that use loops but are more compact and your code was 10% faster on average. ~380cpu ticks vs ~430.
    Also a note for anyone who is doing this with threading, avoid using interrupts. It is not well documented but if you use threading + interrupts Pico will randomly stop working(on interupt), took me two days to figure that one out.
    Cheers!

      Hi o5tusk804 ,
      While i have not done any macro keypad projects, I don't see what you can't.

    Ok I would be very greatfull if you could make this work with instead of a keypad.. a joystick say press down = 2, left = 4, right = 6, up = 8, with up down left right and 5 with button press. output to computer can this be done?

      Hi, thanks for the request. Can you explain in a bit more detail, I am not sure of exactly what you want and for what purpose.
      Cheers!

      @@MakingStuffwithChrisDeHut o so I have a game that uses movement with the number pad then the number 5 is used as a mappable key in game like potion to heal. I would like to use a joystick to move around in the game and have my other 4 fingers free for other keyboard use so down on the joystick acts like I am pressing a keyboard keypad #2 and so on is this possible?

      @@Elmorji Ok, I think I understand what you want. I was planning on a circuit python keyboard emulator project in the future, unfortunately, I don't believe that will make it to RUclips until mid-to-late July based on my current schedule.
