During their recent work on the EdgeTX/edgetx repository, Drung focused on resolving a critical hardware feedback issue affecting the device’s power LED indicators. By analyzing and correcting the LED control logic and updating GPIO mappings, Drung ensured that the power LEDs now display accurate colors and reliable on/off states, directly improving user feedback and device reliability. This work required a strong command of C++ programming, embedded systems, and hardware interfacing, as the solution involved low-level adjustments to both software logic and hardware definitions. The depth of the fix demonstrates careful attention to system behavior and practical embedded engineering challenges.
