This project involves porting an existing graphics display driver library from Arduino to AVR GCC for the ATmega1284 microcontroller. Adafruit produces the RA8875 Driver Board for 40-pin TFT displays, along with an Arduino library for controlling the onboard RA8875 graphics controller chip. The goal is to take this well-documented Adafruit RA8875 library and adapt it for compilation and use with the AVR GCC toolchain on the ATmega1284. This will require analyzing and modifying the library code to make it compatible with AVR GCC while retaining the core graphics functionality. It is also necessary to port the example sketch code provided in the Arduino library to behave properly when compiled for the ATmega1284 with AVR GCC. Once complete, the adapted driver library and examples should allow users to leverage the RA8875 graphics driver in projects using the ATmega1284 without requiring the Arduino framework. Strong skills in AVR GPIO, SPI, and low-level C programming for 8-bit AVR microcontrollers are needed to successfully complete this task.
