(Nearly) all of the Adafruit graphical displays are based on a core set of functions that are provided by the GFX library. These include drawing pixels, lines, rectangles, circles, round-rectangles, triangles and text. For details on how to use the GFX library, visit the tutorial page. Note that for this monochrome display, only WHITE (VFD pixel lit) and BLACK (VFD pixel off) are supported.
