I'm sure someone has already done this, but I haven't found it, so hopefully this helps.
I'm a hardware guy. I've always meant to get into coding, and this little project really gave me a nice 101 crash course. Still not entirely sure what I'm doing, but I have a fuzzy idea...
THANK YOU HASU FOR YOUR AWESOME WORK! ^_^
And thank you matt3o for your very awesome intro guide to his firmware!

}Next up is to etch some PCB's.
Also, a couple of questions since I need to take a break from looking at code:
The number lock. I'm assuming the easiest solution would be to map a new layer with the Shift+Scroll Lock combo?
LED support! I tried changing the led file to write to the teensy's LED as an experiment, but I'm not getting anything. Which brings me to...
I2C i/o expander! I would like to be able to have control of status LED's as well as some backlighting. Sure I could get some teensy ++'s, but the regular teensy + an expander is significantly less expensive. Any experience/tips with those?
Thanks!
I have a nice Wheelwriter keyboard I'd like to make a controller for.
