Demo board description

This board was developed in orde to provide a tool for engineers, wishing to demonstrate and evaluate this LCD driver, and to get hands-on experience with writing code for it. Code written using this board can serve as an example for the final application. This enables rapid prototyping. The board can be connected to any existing application with either I²C-bus or SPI-bus interface. This application then needs to provide also the power supply, with the supply voltage ranging from 2.5 V to 5.5 V.
