Lingzhi Chen developed and integrated a dedicated power management library for the TL321X platform within the telink-semi/hal_telink repository, focusing on embedded systems and device driver development using C. The work enabled conditional low-power operation by linking the new library only when power management is enabled through CONFIG_PM, ensuring no overhead for builds that do not require these features. This approach improved energy efficiency and battery life for TL321X devices in real-world scenarios. Lingzhi’s contribution enhanced the modularity of the hardware abstraction layer, supporting faster adoption of power-saving features while maintaining a clean and maintainable build process.
