During June 2025, Jiayadong worked on the tiiuae/nuttx repository, focusing on embedded systems and driver development in C. He addressed a critical color rendering issue on the esp32s3-box-3 platform by identifying and correcting a byte order mismatch in the ILI9342C LCD driver. By swapping color data from little-endian to big-endian before transmission, Jiayadong ensured accurate color display and improved hardware reliability. This low-level debugging and hardware interaction reduced development and debugging time for ESP32-S3 deployments. His work demonstrated careful attention to hardware-software integration and contributed to more robust and maintainable display functionality for the platform.
