README
README.mdthis is my custom key macropad using a seeed xiao rp2040. i built it mostly because i wanted something actually to help with Spotiy and shortcuts
it’s got a rotary encoder for volume, a small oled screen, and a 3x4 matrix its daily stuff like oping apps shuffle music ect. right its
open firefox, spotify, discord control volume with the knob mute/unmute my mic toggle vpn run a timer that shows how long i’ve been working show status on the screen (mic, vpn, timer) still depding on wat annimation to use
firmware is just circuitpython since it’s easy to change stuff quickly. might switch to qmk later but this works fine for now.
future stuff i might add:
better screen ui (icons instead of text) animations different modes depending on what i’m doing proper linux integration instead of basic shortcuts
