I'm currently building a phantom keyboard. Yesterday, I finished soldering the teensy, and installed the firmware.
I tested it out on notepad, and it seems to be registering random keys for some reason.
Here's what I got when I pressed "7"
77777777777777277757727777777777777777717775777777777=7777777777777777777777777177
Other buttons act similarly, with keys in the same row being registered.
I don't think I've made any soldering bridges around the teensy. I've tested it with a mutimeter, and the pads for the numbers being registered aren't even next to each other.
Any help would be appreciated.
Thanks!
