Worked on the EdgeTX/edgetx repository to address a critical build issue affecting the Color LCD startup and shutdown logic. Focused on C++ development, the work involved identifying and correcting a macro definition typo in the startup_shutdown.cpp file, which had previously caused compilation failures across different configurations. By removing an extra closing parenthesis in the macro, the fix restored reliable compilation and stabilized support for color LCD features. This contribution demonstrated attention to detail in bug fixing and a methodical approach to troubleshooting build errors, utilizing C++ and macro management skills to ensure consistent and dependable code integration for the project.
