摘要
HCMS 2 90 3是一种高性能、易于使用的CMOS数字字符点阵显示的发光二极管显示器(LED)芯片。文中在简要介绍HCMS 2 90 3结构特点、通信协议的基础上 ,介绍了利用HCMS 2 90 3作为显示器、单片机AT89C5 2作为控制器、计算机作为数据源而实现数字画面的显示、切换和控制的原理 ,以及硬件结构和软件设计等。该设计已被用于工程实践 ,获得了满意的效果。
This paper introduces a method of using HCMS-2903 as the display, AT89C52 as the controller, a computer as the data source, X25045 as the watch dog, and MAX3084 as the serial communication connector between the single-chip microcomputer and the computer, plus the hardware such as the keyboard and the knob switch to realize the theory, hardware architecture and the software design of the display, switch and control of digital pictures on the basis of the architecture characteristics, scheduling relationship and communication protocol. This design showed satisfying results in practice.
