  • How do you turn off the system messages? It's hard to seriously use this in a project if every time you change the backlight (or any other setting) you see that confirmation briefly on screen. Some versions of the firmware apparently use 0x2E and 0x2F to enable/disable that but mine doesn't respond to those messages at all.

  • I'd really like to see actual documentation for these Qwiic boards. I'm trying to interface with them from a non-arduino processor and writing my own (non C) libraries is difficult based on the barely commented arduino libs. Every other i2c IC comes with good register lists, state machines, ... and so on.

    Spoiler alert, the register list from the arduino lib for this keypad is wrong and I had to read the (user supplied) python lib below to find the real values. The sparkfun library lists them as 0x01,2,4,5,6,7,8 but the actual registers (not surprisingly) are 0x01,2,3,4,5,6,7.

    It's fine, I figured it out.... It's not like it doesn't work. I just... expected more from sparkfun. Pretty unprofessional on this front.

No public wish lists :(
