Arduino Library – Adafruit GFX
Installatie van Arduino IDE libraries: Arduino info
This is the core graphics library (Adafruit GFX) for all our displays, providing a common set of graphics primitives (points, lines, circles, etc.). It needs to be paired with a hardware-specific library for each display device we carry (to handle the lower-level functions).
1) Rename the uncompressed folder Adafruit_GFX.
2) Confirm that the Adafruit_GFX folder contains Adafruit_GFX.cpp and Adafruit_GFX.h
3) Place the Adafruit_GFX library folder your <arduinosketchfolder>/Libraries/ folder. You may need to create the Libraries subfolder if its your first library.
4) Restart the IDE.
