 * Concept and Microcontroller Firmware - Daryl Rictor, Grant Searle
 *
 * The display microcontroller is wired as follows:
 * pin 28 (SCL) ==> Display pin 28 (SCL)
 * pin 27 (SDA) ==> Display pin 27 (SDA)
 * Arduino Reset ==> Display pin 1 (Reset) - Reset (Optional)
 *
 * The two I2C data lines need to be pulled high to 5V via 2K2 resistors.
