got this for around a dollar from aliexpress and didnt have any real usescases for it. so I made some useless projects, this repo is a collection of those. contains libs for uart and a basic usb keyboard interface for the atmega32u4.
all these projects have their own make files for compiling and flashing, they all work the same.
to compile only: make hex
to compile, if needed, and flash it to the board: make flash, keep in mind you'll have reset the board for it accept being flashed
to clean compiled files:make clean
deps: avr-gcc, avrdude, make
