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 ..................................... ........
