Interfacing PICmicro® MCUs to an LCD Module

From Microchip Technology, Inc.

This application note interfaces a micrange PICmicro device to a Hitachi LM032L LCD character display module, with a two line by twenty character display. LCD modules are useful for displaying text information from a system. In large volume applications, the use of custom LCD displays becomes economical. The routines provided should be a good starting point for users whose applications implement a custom LCD. This source code should be compatible with the PIC16C5X devices, after modifications for the special function register initialization, but has not been verified on those devices.
