Summary
🤩
RockstarCc Li is an embedded systems engineer with a decade of experience focused on IoT and real-time OS platforms, currently developing at Nuvoton Technology in Taiwan. He contributes to major open-source RTOS projects such as Arm Mbed OS and Zephyr, where his work spans board support, drivers, low-power tickers, SPI DMA adaptations, and USB/USB-C and I2C integrations for Nuvoton platforms. Known for fixing subtle data-loss bugs (e.g., in an ESP-AT Wi‑Fi driver) and refining hardware-specific clock and critical-section handling, he blends low-level firmware expertise with practical system reliability improvements. Comfortable navigating both peripheral controllers and power/clock domains, he brings a hardware-aware software mindset that accelerates product integration across microcontroller families.

Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:27 reviews, 1153 commits, 201 PRs in 6 years 4 months
Contributions summary:Cc contributed to the development of embedded systems within the Arm Mbed OS, specifically adding support for the NUMAKER_PFM_NUC472 board, which involved defining hardware-specific configurations. They replaced low-level disabling/enabling functions with critical sections. They also updated the low-power ticker to enhance its behavior. Furthermore, they adapted the existing SPI DMA transfer mechanisms to ensure compatibility with the M2351 series.
