PROFILE
Gianantonio Pezzullo
Over four months, Michael Mackenzie enhanced the Mu2e/otsdaq-mu2e repository by developing and refining embedded systems features in C++. He delivered robust CFO loopback testing with software-controlled loops, ROOT-based output, and statistical delay analysis to improve diagnostics and reproducibility. Michael stabilized hardware interface initialization by updating clock synchronization defaults and implemented per-bit validation for DTC control registers, reducing misconfiguration risks. He modernized test infrastructure by centralizing environment setup and introduced operation timeouts with detailed logging for faster debugging. His work demonstrated depth in C++ programming, embedded systems, and hardware interface configuration, resulting in more reliable, maintainable, and observable system operations.

Jan 1, 2026January 2026 highlights for Mu2e/otsdaq-mu2e: Test Infrastructure Modernization and Stability/Observability improvements were delivered to improve test reliability, debugging speed, and maintainability. Key changes: 1) Test Infrastructure Modernization: Moved environment variable setup to a shared utility to streamline test initialization and improve maintainability (commit 12c07cae6300ff1564ef8a4c85b6d95eb1df3f3a). 2) Internal stability and observability enhancements: Introduced read/write operation timeout with ROC link ID logging for better debugging and user feedback; refactored DTC control register validation error handling by introducing a dedicated result code variable for clearer error state separation (commits 773cb005888c5d5181c6e6b6a5f8aa050a5ddead and e6732ef3398c6b1aeece9f115cfeae0b4d5f597e).

Sep 1, 2025September 2025 monthly summary for Mu2e/otsdaq-mu2e. Delivered the CFO Sample Clock Edge Default Update as a key feature to stabilize CFO interface initialization and clock synchronization. Updated default from 2 (auto-find) to 0 (rising-edge) in DTCFrontEndInterfaceImpl.cc. Implemented via commit e92b9c029919a8a6b48a2efec7beda0237bbad16 ('Change CFO interface setup default'). Impact: Improved startup reliability of CFO timing, reduced initialization drift, and smoother data-taking readiness. Skills demonstrated: C++ code changes, interface configuration, clock-domain awareness, Git-based version control and change management.
