Programming

The demo shows how to use the SPI LCD library to communicate with the LCD with HD44780 compliant controllers in 4-bit mode via the SPI interface. It also uses the PWM for the backlight and the on board digital potentiometer, for controlling display contrast, which can be accessed through SPI. The demo iterates through all the values for the backlight and the contrast intensity.
