PICDEM 2 USER’S GUIDE

Chapter 6. LCD Demo

The kbd4bit.asm and kbd8bit.asm programs demonstrate how to

interface to an LCD module in both the 4-bit and 8-bit interface modes. The

programs read the keypad and output the keypresses to the LEDs and the

LCD module. Two include files on the disk, lcd4bit.asm and

lcd8bit.asm,

have all of the routines necessary to run the display.

For more information on LCD operation, please refer to Interfacing PICmicro

Microcontrollers to an LCD Module - AN587. For detailed information on the

PICDEM 2 hardware, please refer to Appendix A.
