The Arduino MKR RGB library allows you to draw on the MKR RGB Shield using some very basic functions. This library is also the software interface necessary to create more complex graphics using the ArduinoGraphics Library.
This library is the one you should use to create the object YourScreen that you find in the examples of the ArduinoGraphics library. You may choose any label for your matrix objetct as far as you use that label instead of YourScreen label.
To use this library:
#include <ArduinoGraphics.h> #include <Arduino_MKRRGB.h>
Note: Arduino MKR RGB library depends of the ArduinoGraphics library.
