Arduino 16*64LED屏滚动文字
本帖最后由 conjee 于 2013-5-30 22:33 编辑以前买的一块16*64LED屏，行选采用两片595位移寄存器芯片级联，数据输出采用8片595位移寄存器芯片级联。
显示效果如下：
完整的代码如下：
#define DataCLK 4
#define DataOUT 3
#define DataSTB 2
#define DataEn 5
#define RowCLK 10
#define RowOUT 9
#define RowSTB 8
#define uchar unsigned char
#define uint unsigned int
uint K=1;//移动速度控制变量。
uchar col,disrow; //列移动计数变量。行扫描计数变量。
uint words; //字形码计数变量。
uchar BUFF; //64列时应将数值设为11
uchar HZ[]=

你这屏什么接口呢，接线图发来看看吧
结合程序与arduino接口：
:lol 很强大，没用arduino的spi接口吧？ 关注一下，有这方面的用途 楼主大大，求模块的原理图！！[email protected] 有没有人用字库芯片来控制的，就不用取模了
