PROFILE

Glenn Andrews

Worked on Zephyr4Microchip/zephyr and nxp-upstream/zephyr repositories, focusing on embedded systems and driver development using C. Delivered a configurable baud rate feature for the 1-Wire driver, enabling Overdrive mode support and improving compatibility with devices like the DS2488 while maintaining backward compatibility for standard-speed devices. Enhanced the State Machine Framework by adding instrumentation hooks to track transitions and error states, which improved debugging and test coverage. Addressed a reliability issue in coredump printing by correcting error handling in coredump_shell.c. Emphasized robust testing, debugging, and code quality throughout, contributing to more dependable workflows for embedded development teams.

February 2026 monthly summary for Zephyr4Microchip/zephyr. Focus was on enhancing 1-Wire Overdrive support and driver configurability. Key feature delivered: added configurable baud rate for Overdrive mode in the 1-Wire driver to improve stability and compatibility with Overdrive-only devices such as DS2488. The change includes a user-configurable baud rate parameter and an adjusted zero-bit pattern for Overdrive mode, while preserving standard-speed timings for non-Overdrive devices.
