// This program is a demo of most of the functions
// in the library.
//
// This program requires a Nokia 5110 LCD module.
//
// It is assumed that the LCD module is connected to
// the following pins using a levelshifter to get the
// correct voltage to the module.
//      SCK  - Pin 8
//      MOSI - Pin 9
//      DC   - Pin 10
//      RST  - Pin 11
//      CS   - Pin 12
