 | Code: /* FILE: HCuOLED_Things_Example DATE: 16/04/15 VERSION: 0.1 AUTHOR: Andrew Davies REVISIONS:
12/03/15 Created version 0.1
This example uses the line, rectangle and bitmap graphic functions together with the INVERT DrawMode to create a simple animation.
To use this example connect your uOLED display to the following pins of your Arduino:
MODULE..........ARDUINO GND.............GND VCC.............3.3V D0 (CLK)........D13 D1 (DATA).......D11 RST (RESET).....D8 DC..............D9 CS (SS).........D10
