Description: 1. LED的显示原理：
16×16扫描LED点阵的工作原理同8位扫描数码管类似。它有16个共阴极输出端口,每个共阴极对应有16个LED显示灯，所以其扫描译码地址需4位信号线（sel0-sel3），其汉字扫描码由16位段地址（l0-l15）输入。 通过时钟的每列扫描显示完整汉字。
2. 本试验实现输出“欢迎光临”四个汉字，采用两种格式输出：（1）依次从右向左连续输出；（2）单个汉字从上及下刷新输出。
-1. LED display Principle: 16 × 16 dot matrix LED scanning the working principle of the same 8-bit digital tube similar scan. It has a total of 16 cathode output ports, each corresponding to a total of 16 cathode LED display lights, so the scan decoding addresses of four signal lines (sel0-sel3), its characters scanned by the 16-bit code segment address (l0- l15) input. Through the clock out of every scan revealed a complete character. 2. In this study, the achievement of output, " Welcome to the" four Chinese characters, the use of output in two formats: (1) followed by continuous output from right to left (2) a single character from the previous and the next refresh the output.

Description: 24*64点阵屏
64*24点阵LED点阵显示板源代码
1：初始通电时灯泡全亮，必需通过程序运行才能避免。这虽然说无伤大雅，但却也是一个弊端。原因是裸片MCU各个口都是高电平的原因，我在设计时未考虑周到。
2：CD4094穿行数据传输级联，现扫描顺序反了，导致编程稍微困难一些。目前顺序是这样的：一共64列嘛，从8开始的，8-7-6-5-4-3-2-1； 16-15-14-13-12-11-10-9；24-23-22-21-20-19-18-17-24* 64 dot matrix screen 64* 24 dot matrix LED dot matrix display source code 1: the initial full-power when the light bulb must be run through the procedure to avoid. Although this innocuous, but it is also a disadvantages. The reason is that I die MCU are high in all of the reasons, I am not taken into account in the design and thoughtful. 2: CD4094 cascade through data transmission, is the order of the anti-scanning, resulting in slightly more difficult programming. At present, the order is this: do a total of 64, from 8 to start the ,8-7-6-5-4-3-2-1 16-15-14-13-12-11-10-9 24-- 23-22-21-20-19-18-17 ..................................... ........ Platform: |

Description: "16×16点阵"同一时间只能显示一个汉字
"6个16 ×16点阵(作弊)"是修改了LED的“Minimum Trigger Time”的，能同时显示6个汉字。
实际中不知道LED能否达到0.1ms的显示速度，如果能的话，"6个16×16点阵(作弊)"还可以用，呵呵，否则就只能仿真玩玩了：）。
由于这里的LED采用横向扫描，所以如果要实现“全屏滚动”还是比较麻烦的，不知道其速度能否跟上，如果是纵向扫描还容易一些。-" 16 × 16 dot matrix" at the same time can only display a Chinese character " 6 16 × 16 dot matrix" at the same time can only display a Chinese character " 6 16 × 16 dot matrix (cheating)" is amended LED' s " Minimum Trigger Time " , the six Chinese characters can be displayed simultaneously. Reality, do not know if LED display can achieve the speed of 0.1ms, and, if so, " 6 16 × 16 dot matrix (cheating)" can also be used, Oh, otherwise, they can play with simulation of a:). As used here, LED horizontal scan, so if you want to achieve " full screen scrolling" or cumbersome, and do not know whether to keep up with its speed, if the vertical scanning is also easier.
