Developed and delivered the Troyle macro_keys_dual Macro Keyboard Configuration for the qmk/qmk_firmware repository, expanding macro-keyboard support to include dual rotary encoders and customizable keymaps. This work, implemented in C and leveraging embedded systems expertise, broadened hardware compatibility and streamlined user setup for macro-key devices. The approach emphasized maintainability and future extensibility, aligning with project standards through clear commit messaging and traceable pull requests. By focusing on keyboard firmware development and utilizing both C and JSON, the contribution enabled more flexible user workflows and laid a foundation for integrating additional macro-key devices within the firmware ecosystem moving forward.
