I got the Feather OLED to work as a 12C device on the RaspBerry PI zero. It actually works great and there is barely a noticeable lag. I am trying to figure out if I can get the buttons on the OLED to work. I wired them up but for some reason the GPIO pins (using pins 5, 6, 13) are always low. Do I need a pull-up resistor to get the values of the pressed switches to stick? And if yes what size?
I would have tried this out if I had a resistors but before I go buy them wanted to confirm I am going down the right path.

Re: Raspberry Pi Zero and Feather OLED 164x32
The RasPi's GPIO pins have built-in pull up resistors that you can enable. The code to do it varies from one language to another, but should be mentioned in any documentation that tells how to set the pins up as inputs or outputs.
