Abstract

This paper introduced the interface design of dot-matrix LCD module based on inter HD61202 controller and 8031′s parallel expanding chip 8255A, and gave the single set-reset control of PC port on 8255A. The fundamental conditions of LCD normal operating, relative program and programming process diagram were presented.
