4-bit serial interface

4-bit serial interface is similar to SPI (3-bit serial interface) but the bit to indicate if the information being sent is data or command is communicated to the LCD module using a separate pin D/!C.

You can take the examples of the Nokia knock-off LCD module from Sparkfun and make a small change to the code to make it work with this 4-bit interface.

In the 3-bit serial interface, you send 9 bits per data or command, the additional bit indicating Data or Command. With this LCD module, you send 8 bits per data or Command, and the 4th bit D/!C is used to indicate Data or Command.
