Ola Huse developed a feature for the nxp-upstream/zephyr repository that enables the QDEC STM32 driver’s prescaler to be configured directly from the Device Tree, bringing its configuration approach in line with other drivers such as counter and pwm. Working primarily in C and leveraging expertise in device driver development and embedded systems, Ola modified the qdec_stm32 driver to utilize the prescaler value specified in the Device Tree. This change addressed consistency across driver configurations and improved maintainability for embedded projects using Zephyr. The work demonstrated a focused, in-depth approach to aligning driver behavior within the Zephyr ecosystem over one month.
