Hexidraw is a library for drawing on the Hexiwear's OLED. Be aware that it is not very optimized, so drawing may be slow, especially when drawing on large areas of the screen.
Please see the wiki for API documentation.
Features:
- Screen fill with a color
- Drawing filled rectangles
- Drawing circles with a set radius and line width
- Setting individual pixels
- Turning on and off the OLED's sleep mode
- Drawing images
