Worked on the EdgeTX/edgetx repository to resolve a critical issue affecting the power LED feedback system. Addressed incorrect LED color display and unreliable on/off behavior by updating the LED control logic and adjusting GPIO definitions, ensuring accurate visual feedback for users and improving hardware reliability. The solution involved in-depth work with C++ programming, embedded systems, and hardware interfacing, focusing on precise control of hardware indicators. This targeted bug fix enhanced the user experience by providing consistent and reliable power-state indication. The work demonstrated careful attention to hardware-software integration and contributed to the overall stability of the embedded platform.
