PS/2 Mouse with ATMEGA328p

Welcome to the repository for my ATMEGA328p-based PS/2 mouse project, developed as part of my computer engineering capstone. This comprehensive collection encompasses the source code, PCB files, schematics, debugging waveforms, and images, providing a detailed insight into the design and implementation process. This PS/2 mouse, powered by the versatile ATMEGA328p microcontroller, seamlessly operates over the PS/2 protocol. The project has been validated to work flawlessly with three different sensors: ADNS3050, PMW3360, and PMW3389.
