documentation - troubleshooting about ergodox-firmware HOT 3 CLOSED

This firmware doesn't currently have a debug mode - and looking at the debug mode for the tmk_keyboard, I don't really see how it's worth the effort (for hardware debugging), since it's not significantly easier than just pressing keys and seeing if they do what they're supposed to (send a character, shift a layer, etc.). Past that, I suggest using a multimeter and checking all your solder joints, and double (and triple... lol) checking that everything matches the diagrams - if you're using the stock firmware and wiring everything up to match, you can take a look at this file (download first, then view) - I think it's the simplest. You can also take a look at the PCB design files on http://www.ergodox.org/ if you want.

This is of course assuming that your Teensy is working in the first place - the easiest way to double check that would probably be to flash it with the blinky program (from PJRC).

Dunno if that helps... Hardware debugging is kinda hard to do much with in software (and to be honest, this is my first project this close to hardware). Hope you get it working!

Thanks!

I've been trying to triple check that everything matches the diagrams -- is the diagram in src/keyboard/ergodox/circuit-diagram.svg still up to date?

Other than that, yeah, it looks like i hosed my teensy. Like they say... "If you're trying to program a MCU when your blinkenlights don't blink, you're gonna have a bad time..."

Lol. Sorry about your Teensy :/ .

The diagram in src/keyboard/ergodox/circuit-diagram.svg is up to date - I briefly checked it just now, and I remember updating it when Fredrick updated the PCB a while back. That said, the PCB design file is the only one that empirically can't be wrong, since it's what the PCBs (which seem to work :) ) were printed from.

Now that I think of it, you also might want to check out the firmware's teensy and mcp23018 documentation, if you haven't already. There're not too long to read through, I think, and they're the notes I wrote / used when I was breadboard testing.
