Hello, I am building a custom split keyboard, with a hand wired matrix, using teensy and TMK firmware, and it isn't working right. I have only done the right piece so far.
Here are the issues:
When I press a number key, it activates all keys in the column. Same thing happens with backspace key (its in same row as number keys).
I can only get P ; and / to work if i press the 0, otherwise they dont work.
Also, if I press any key in the bottom row, it activates every key above it, except for the red key.
Any thoughts on what the issue could be? Hardware, software? I have redone the software a bunch, so I think its fine, but how would I troubleshoot/fix the hardware?
