ENDMAX7219的c程序/*---------------------------------------------------------

*

程序说明

*

*

1、本程序已经通过测试，非常好用；

*

*

2、在非译码方式下编码和一般书上写的不一样，请注意；

*

*

3、每次送显示的时候先初始化一次；

*

*

4、在设计电路或制作试验板时注意添加Vcc到GND之间的电容，*

*

一个10vF的电解电容和0.1vF的陶瓷电容。并在DIN、LOAD、*

*

CLK到GND之间接入30pF的瓷片电容。

}我正好有个7219，一直想学一下，51节就搭个电路看看，谢谢。[电烙铁]2005-4-22

18:00:21我有更简单的[rq88]2005-4-22

18:38:00我有更简单的那就发上来大家都看看嘛

[bush636]2005-4-22

21:19:13我有AVR

C++的

AT90S2313通过（有图）(附图)[Sunnyyonkers]2005-4-23

14:27:58要注意到时序正确就行了，另外电压一定要够，否则一定会出现乱

码。

我先给出一个我做的一个通用驱动。
