|
* Arduino Terminal Library - Dave Curran (www.tynemouthsoftware.co.uk)
|
|
* 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.
