KMK: Mechanical keyboard firmware for humans (and ARM microcontrollers)

KMK is a firmware for (usually mechanical) keyboards, written in MicroPython and CircuitPython, heavily inspired by QMK (and with some additions of our own). Python may not be the fastest thing on the planet, but it's a joy to write, and bringing that ease of maintainership to keyboard firmware (often a world of C and all the crazy error states C can provide) opens up custom keyboards to whole new demographics. KMK currently only supports handwired keyboards (see "Supported Devices" below), but work has begun on both ports to existing keyboards, as well as converter devices to allow existing keyboards with Pro Micro pinouts to use KMK-supported microcontrollers. As always in open-source, KMK is a work in progress, and help is welcome!

• Kyle Brown (@kdb424)

This project also owes a $BEVERAGE_OF_CHOICE to some wonderful people in the ecosystem:

• Jack Humbert (@jackhumbert), for writing QMK. Without QMK, I'd have never been exposed to the wonderful world of programmable keyboards. He's also just an awesometastic human in general, if you ever catch him on Discord/Reddit/etc.

• Dan Halbert (@dhalbert), for his amazing and unjudgemental support of two random dudes on Github asking all sorts of bizzare (okay... and occasionally dumb) questions on the MicroPython and CircuitPython Github projects and the Adafruit Discord. Dan, without your help and pointers (even when those pointers are "Remember you're working with a microcontroller with a few MHz of processing speed and a few KB of RAM"), this project would have never gotten off the ground. Thank you, and an extended thanks to Adafruit.
