Month: 2025-08 — ESP-IoT-Solution: Delivered SM16825E lightbulb driver support and reliability improvements. Summary of deliverables: Implemented a dedicated SM16825E driver with new driver files, configuration options, and an RGBWY LED usage example, enabling low-power mode processing and flexible GPIO configuration. Also fixed curve table indexing in the HAL layer (hal_get_curve_table_value) to ensure correct input scaling and bounds-checking for the SM16825E driver. These changes expand hardware compatibility, improve runtime reliability, and enhance energy efficiency. Demonstrated embedded C and HAL-level driver development, low-power design, and robust version-control practices.
