Arduino Giga Display Shield RGB LED driver

[omeErik]

On the Arduino Giga R1 Wifi, there is an RGB led that can be controlled. This is well documented.

If you stack the Giga with a Display Shield, then on the Display Shield there is another RGB led, less well documented and not accessible easily. This is unfortunate, since the Display Shield led is facing forward, while the Giga led is facing backward.

The Display Shield led is driven by a special chip that allows it to do regular stuff like setting intensities and colors, while also allowing for patterns in sleep mode of the controlling MCU. Here is a driver that allows easy access to all the chip has to offer.

More information in the readme.
