摘要
单片机自20世纪70年代问世以来，以极其高的性价比受到人们的重视和关注，所以应用很广，发展很快。单片机的优点是体积小、重量轻、抗干扰能力强，对环境要求不高，价格低廉，可靠性高，灵活性好，开发较为容易。在我国，单片机已被广泛应用于工业自动化控制、自动检测、智能仪表、家用电器等各个方面。在现代工业控制和一些智能化仪器仪表中，越来越多的场所需要用点阵图形显示器显示汉字。汉字显示方式是先根据所需要的汉字提取汉字点阵（如16×16点阵），将点阵文件存入ROM，形成新的汉字编码；而在使用时则需要先根据新的汉字编码组成语句，提取相应的点阵进行汉字显示。
本设计由单片机AT89C51的P0口传送数据，P1口和P0口配合选择所要显示的行，P2口和P0口配合选择所要显示的列。再由 8×8点阵LED显示器及其他一些外围电路显示所要求的显示的点阵式汉字、图形以及动画。其中的汉字编码由Zimo221应用程序提取。

The single chip Microcomputer is the volume small, the weight light, the antijamming ability strong, is not high to the environment request, price inexpensive, reliability high, flexibility good, the development is easy. General engineers and technicians after study related monolithic integrated circuit knowledge, also can depend upon the single chip Microcomputer system which own strength develops hoped, and may obtain the highereconomic efficiency.
