Using PIC16C5x Microcontrollers as LCD Drivers

From Microchip Technology, Inc.
 

 
This application note describes an LCD controller implementation using a PIC16C55 microcontroller. This technique offers display capabilities for applications that require a small display at a low cost, together with the capabilities of the standard PIC16C55 microcontroller. We start by an overview of LCD devices and their theory of operation followed by software implementation issues of the controller. The source code for controlling a multiplexed LCD display is included in Appendix A.
