Worked on the uw-midsun/fwxvi repository to enhance I2C communication reliability within embedded systems firmware. Focused on improving hardware interaction by implementing robust error handling and refining pin configuration logic in C, which addressed potential points of failure in I2C transactions. Developed and integrated an API smoke test to validate I2C usage in realistic scenarios, ensuring that the interface performs reliably under typical operating conditions. This approach not only reduced integration risk but also improved test coverage for a critical hardware interface, supporting future maintainability. The work leveraged skills in embedded systems, firmware development, and I2C communication protocols.
