单片机驱动16*16点阵源程序(多种驱动方式)Proteus8.15仿真

ID:579397 · 发表于 2023-1-28 05:25

设计了四套驱动方案：1、154+595驱动 2、154+P口驱动 3、595驱动 4、单片机P口驱动
程序为文字左移显示
供初学者参考

单片机16×16点阵（154+595驱动）源程序如下:

#include <intrins.h> //函数,应用于程序设计
#include <reg52.h> //单片机头文件
/**********接口说明**********/
sbit SER=P3^0; //DS 第14脚串行数据输入
sbit SRCLK=P3^1; //SH_CP 第11脚数据输入时钟线
sbit LATCH=P3^2; //ST_CP 第12脚输出存储器锁存时钟线
sbit OE=P3^3; //OE 第13脚输出有效,低电平有效
/**********全局变量**********/
unsigned int word=1; //数据位指针

unsigned char time=5; //走字速度,可修改
unsigned char code segout[8]={0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80}; //列扫描数组
