Game Boy Link communication, stm32f4 side

This is the microcontroller side of a project that allows communication between a physical Game Boy Game Link Cable and a computer.

The code is written in C and uses the libopencm3 library to control the STM32F4. I have used a NUCLEO-F411RE, but other STM32 microcontroller should work too.

Three main modes for the serial protocol are implemented:

  • Sniffing
  • Master
  • Slave


You can read the complete details of this project in my blog posts:
