单片机应用的不断深入带动了液晶显示技术的日新月异。鉴于当今液晶显示已经成为人机界面的关键技术。文中对基于51单片机与不带汉字库的YD-602S彩色液晶显示器的接口技术进行了研究。并在简要介绍液晶显示的原理及功能的基础上,给出了该显示模块与单片机的多种接口电路;同时给出了单片机接口的基层软件设计方法。
Microcontroller applications continue to drive the ever-changing liquid crystal display technology. In view of today’s liquid crystal display has become the key technology of the man-machine interface. In this paper, the interface technology of YD-602S color liquid crystal display based on 51 single-chip microcomputer and without Chinese character library is studied in this paper. Based on the brief introduction of the principle and function of the liquid crystal display, a variety of interface circuits of the display module and the singlechip are given. At the same time, the design method of the base software of the singlechip interface is given.
