Hey there,
I have been in the process of building my first custom keyboard (Ferris sweep), I have just finished flashing my to halves, and wanted to test it out, and it turns out that one of the keys doesn’t work. My guess is a poorly soldered joint.
My question for you are, what are my options for troubleshooting this problem, and finding the source of it? (I’m guessing that it could both be from the micro controller, and the key it self)
Thank you for reading, and this great community
With a multimeter there are tons of things to check!
You can put it into OHM mode and test diode direction, the traces, and finally the switch itself!
Normally Ive had bad switches you could pop it open and make sure something isnt wrong or if it’s easy enough swap it with a spare
