SomeRandomBloke 2:a7d4ac7ed08a 2 This is the core graphics library for all our displays, providing a common
SomeRandomBloke 2:a7d4ac7ed08a 3 set of graphics primitives (points, lines, circles, etc.). It needs to be
SomeRandomBloke 2:a7d4ac7ed08a 4 paired with a hardware-specific library for each display device we carry
SomeRandomBloke 2:a7d4ac7ed08a 5 (to handle the lower-level functions).
SomeRandomBloke 2:a7d4ac7ed08a 6
SomeRandomBloke 2:a7d4ac7ed08a 7 Adafruit invests time and resources providing this open source code, please
SomeRandomBloke 2:a7d4ac7ed08a 8 support Adafruit & open-source hardware by purchasing products from Adafruit!
