I finally had some time today to compile #VIAL #QMK and investigate why the OLED of my #Mysterium keyboard (https://42keebs.eu/shop/kits/with-discrete-mcu/mysterium-ansi-iso-tkl-kit-black-white/) did not work. Turns out, it always worked, but it just displayed nothing since the firmware did not contain any code for it. Implementing the corresponding method worked as expected. Now I only need to figure out useful information to display. #keyboard #keyboards
