James Kidd / Adafruit_GFX_MBED

Port of the Adafruit_GFX library for use in MBED. This is the core graphics library for all Adafruit's displays, providing a common set of graphics primitives (points, lines, circles, strings,bitmaps. etc).

infotech1 0:50ff23c02d57 2 This is the core graphics library for all our displays, providing a common
infotech1 0:50ff23c02d57 3 set of graphics primitives (points, lines, circles, etc.). It needs to be
infotech1 0:50ff23c02d57 4 paired with a hardware-specific library for each display device we carry
infotech1 0:50ff23c02d57 5 (to handle the lower-level functions).

infotech1 0:50ff23c02d57 7 Adafruit invests time and resources providing this open source code, please
infotech1 0:50ff23c02d57 8 support Adafruit & open-source hardware by purchasing products from Adafruit!
