Added three lights for status indication (ping pong key)
Replaced ec11 with patch type
A patchwork program using arduino, development board link https://github.com/DeqingSun/ch55xduino
The hex file in the compressed package is configured to trigger F1/F3/F5 when the light is on, and trigger F2/F4/F6 when the light is off. The encoder presses F7 to rotate left and F8 to the right to F9, but the trigger is not sensitive and is being solved.
