This code base is for creating a bootloader to be utilized for programming microcontroller flash memory. This program takes a hex file as the input and will parse that hex file and send it to the microcontroller bootloader over a serial UART (commonly referred to as a "serial port" or "COM port").
The companion project to this is the bootypic project. Hopefully, more will follow. GUI provided at bootycontrol.
