SomeRandomBloke 0:08cfbae05724 2 This is the core graphics library for all our displays, providing
SomeRandomBloke 0:08cfbae05724 3 basic graphics primitives (points, lines, circles, etc.). It needs
SomeRandomBloke 0:08cfbae05724 4 to be paired with a hardware-specific library for each display
SomeRandomBloke 0:08cfbae05724 5 device we carry (handling the lower-level functions).
SomeRandomBloke 0:08cfbae05724 6
SomeRandomBloke 0:08cfbae05724 7 Adafruit invests time and resources providing this open
SomeRandomBloke 0:08cfbae05724 8 source code, please support Adafruit and open-source hardware
SomeRandomBloke 0:08cfbae05724 9 by purchasing products from Adafruit!
