Developed and released a hardware watchdog timer library for the Teknic ClearCore platform within the arduino/library-registry repository, focusing on embedded systems reliability. The solution leveraged C++ and direct CMSIS register access, intentionally avoiding third-party dependencies to ensure robust hardware interfacing and compliance. Delivered as version 1.0.0, the library included three example projects and underwent thorough validation using arduino-lint, resulting in zero errors or warnings. Release tagging and documentation were completed to support adoption and future enhancements. This work established a maintainable baseline for watchdog-enabled deployments, enhancing system monitoring and reliability for embedded applications using C++ and CMSIS.
