During the month, this developer enhanced Zephyr OS support for the EK-RA8M1 board by delivering two features across the zephyrproject-rtos/zephyr and Zephyr4Microchip/zephyr repositories. Their work focused on enabling ADC0 channel 4 through a dedicated device tree overlay and adding board-level ADC aliases to streamline integration with ADC sample overlays. Additionally, they implemented a PWM-based overlay to facilitate onboard LED control via GPT PWM. Using C and DTS, they concentrated on device driver development and device tree configuration, prioritizing integration readiness and cross-repository consistency. No bugs were reported, reflecting a focus on new feature enablement and sample alignment.
2026-05 Monthly Summary: EK-RA8M1 board support and ADC/PWM sample enhancements across Zephyr ecosystems, focused on feature enablement and cross-repo consistency. Key features delivered include an EK-RA8M1 ADC overlay for the zephyr ADC devicetree sample, ADC0 channel 4 configuration, and a dedicated io-channels entry; board-level ADC aliases to support ADC sample overlays and device-tree configurations; and a PWM-based overlay enabling GPT PWM control for the onboard LED. No major bugs reported this month; changes were focused on integration readiness and sample alignment.
