PROFILE
Ivan Calderon
Ivca developed and integrated a comprehensive watchdog timer system for the CU-Robotics/firmware repository, focusing on enhancing system reliability and automated fault recovery. Over two months, Ivca implemented a configurable watchdog library in C and C++ for the T4 platform, supporting start, stop, feed, and expiration checks, and ensured robust hardware abstraction through careful header and macro adjustments. The work included refactoring the Watchdog class for clearer APIs and improved timeout configuration, embedding health monitoring directly into the firmware main loop. This approach improved maintainability, enabled early detection of unresponsiveness, and provided a reusable safety mechanism for embedded real-time systems.

Mar 1, 2025March 2025 firmware development focused on system health and reliability. Delivered a watchdog timer mechanism in CU-Robotics/firmware with a refactored API, enabling early detection of unresponsiveness and safer recovery. The work improves maintainability, testability, and overall system uptime. No major bugs fixed this month; the primary value comes from new monitoring capability and clearer code structure.

Feb 1, 2025February 2025: Delivered a comprehensive Watchdog Timer (WDT) system for CU-Robotics firmware (T4). Implemented a WDT library (WDT1-WDT3 and EWM) with start/stop/feed/expiration checks and a default constructor, and integrated it into firmware with configurable parameters and a watcher trigger callback. Added foundational header/macro adjustments to ensure correct watchdog register access. The work improves fault detection, auto-recovery, and system uptime, and provides a reusable safety component for future firmware. Key commits included incremental changes to the CU-Robotics/firmware repository, notably: watchdog added (087b1ae67b08e6243535d22c2f8f9c12ad4cc350); added default constructor for watchdog (4d2bdebcbdb94574d9a8ffd041a6167e957c11ce); Wathcdog Functionality (e0584303b45b9af45acd75c5c7246464e9fddec8); watchdog features (14a47c274489264b041442712e6678623d06bc59).
