本程序是利用arm7控制双色led点阵屏的显示源码。是用ADS软件开发的，希望对各位有用-This procedure is the use of ARM7 control of two-color dot matrix led display screen source. ADS is a software development, in the hope that useful

1、lpc2119的uart0\timer0应用 2、循环冗余校验CRC函数库 3、ASC字符在5*7点阵LED的应用 4、X045的应用函数库-1, lpc2119 of uart0 imer0 Application 2, Cyclic Redundancy Check CRC library 3, ASC characters in the 5* 7 dot matrix LED applications 4, X045 application library

基于ARM7的点阵显示程序，用串入并出74HC164来传送数据，节省I/O口-ARM7-based dot-matrix display program with string into and out of 74HC164 to transmit data, saving I/O port

ARM7内核芯片LPC2104部分源程序 名 称：多功能点阵显屏 功 能：显示文字，时间，图形等 说 明：74HC154做行扫描，74HC164做列数据经74LS373锁存输出由ULN2803A驱动点亮LED,-LPC2104 ARM7-core chip part of the source name: Multi-function dot-matrix display screen: display text, time, graphics and other instruct

ARM7做的LED点阵显示上下左右移动主要是使用与IO口的熟悉和使用-ARM do LED dot matrix display
