-GPIO-based-LED-Driver-in-Linux-. Develop a char device driver to control RGB led display. To test the driver, a user-space application is written to display a lighting sequence of {OFF, R, G, B, R&G, R&B, G&B, R&G&B} where each step of the lighting sequence is with a duration 0.5 second. The lighting sequence should be displayed repetitively and can be interrupted by any mouse button click. If there is a button click, the display should immediately move to the beginning of the sequence.
