I have just started using the Seeed Xiao rp2040 with CircuitPython. I was following the tutorials by Joe Scotto to test a simple 2x2 grid for matrix wiring, but I still need to connect the buttons to ground rather than each other, and all of the pins seem to connect to each other, as in I connected an LED to one of the columns, and it didn't matter which button I pressed but it turned on. Does anyone have any tips on how I can fix the issue? I decided to use CircuitPython rather than QMK, does this make a difference? This is the tutorial that I followed, but just on a different board: https://www.youtube.com/watch?v=7LyziNdFlew And is it worth learning QMK rather than trying to code a macropad in CircuitPython?
