This is a scratchpad of sorts for me to resharpen my skills in bare metal embedded programming. No promises about how pretty this code it, but I hope it will become so (and keep its functionality.)

My main goals are to be able to run basic arduino sketches using just C (and some headers...) and compile it with Cmake and flash using the terminal. Wish me luck!

sudo apt install gcc-avr binutils-avr avr-libc avrdude

# Unplug Arduino
ls /dev/tty*
# Plug in Arduino
ls /dev/tty*
# The difference is the Arduino target!

Navigate to the proper directory.

make # This will compile the code.
make flash # This will compile and flash the Arduino.
