This application note interfaces a midrange 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 pro-
vided 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. AN587
