2023-09-26 (Tu) EWC_Cyberdeck Right hand key mapping

My serial feedback printed a grid with all the addresses on the diode matrix each time I pressed or released a key. The all-in approach was excellent for ensuring nothing extra happened when I pressed a button, but it was messy on the serial terminal. I changed the code to print the address of the switch as "Press: ###" or "Relse: ###." I had to duplicate the code for the second IO expander so that each key had a unique address.

Once the serial data was properly formatted, I copied it to transmit on Serial1, which was connected to the headphone port. I created a map of all my eligible button addresses and recorded which key they represented. The final step will be implementing keyboard actions upon the buttons' presses and releases.
