Developed and delivered a Piezo Buzzer Amplitude Modulation and PWM Enhancement feature for the uw-midsun/fwxvi repository, enabling adjustable sound output through precise PWM control and IRQ-based toggling. The work involved implementing robust initialization routines and structuring PWM signals to ensure reliable and deterministic hardware behavior in embedded systems. Improvements included the adoption of static and fixed-width types, automated linting and formatting via GitHub Actions, and SCons-based formatting enforcement, all contributing to a more maintainable codebase. Demonstrated expertise in C programming, embedded firmware development, and CI pipeline integration, laying the groundwork for faster and more reliable future enhancements.
