Noah Stephens developed low-side power switch support for the AD7124 ADC in the Zephyr4Microchip/zephyr repository, focusing on safer device under test (DUT) switching and automated lab testing. He implemented device-tree driven control by integrating a pd-switch-enable path into the Zephyr ADC driver, allowing hardware engineers to manage DUT power switching directly from device tree configurations. Working in C and leveraging his expertise in device driver development and embedded systems, Noah’s contribution addressed hardware bring-up and test automation needs. The work demonstrated depth in embedded driver integration, aligning software control with hardware safety and automation requirements for lab environments.
