From the project
Academic ECU project in C for the PIC16F877A, with Proteus simulation and KiCad PCB design.
Academic embedded systems project developed for a Microprocessors and Microcontrollers course in the Computer Engineering program at UFSC. The goal was to build an educational ECU prototype that simulates basic combustion engine control while integrating embedded firmware, sensor acquisition, actuator control, an LCD interface, circuit simulation, and PCB design.
