Worked on the rdkcentral/rdkservices repository to enhance the reliability of TV software dimming mode configuration. Addressed a bug where dimming mode values such as 'local', 'fixed', and 'global' were not consistently recognized due to case sensitivity in string comparisons. Implemented a case-insensitive handling approach in C++ to ensure these modes are correctly interpreted regardless of input case, improving cross-platform consistency. Applied embedded systems expertise to deliver a robust fix that prevents set-dimming failures and streamlines user input processing. This work focused on maintaining code quality and reliability within the embedded TV software development environment, emphasizing maintainability and correctness.
