LED矩阵

注意

将OE与GND短接（用板子上的跳线帽）

使用54HC595模块实现控制8*8LED矩阵模块

#include "reg51.h"
#include "intrins.h"

typedef unsigned int u16;
typedef unsigned char u8;

u8 ledNum;

sbit SRCLK=P3^6;
sbit RRCLK=P3^5;
sbit SER=P3^4;
sbit LED=P0^7;

void delay(u16 i)
{
    while(i--);
}

void Hc595SendByte(u8 dat)
{
    u8 a;

    SRCLK = 1;
    RRCLK = 1;

    for(a = 0; a < 8; a++)
    {
        SER = dat >> 7;
        dat <<= 1;

        SRCLK = 0;
        _nop_();
        _nop_();
        SRCLK = 1;
    }
    RRCLK = 0;
    _nop_();
    _nop_();
    RRCLK = 1;
}

void main()
{
    LED = 0;
    ledNum = ~0x01; 
    while (1)
    {
        Hc595SendByte(ledNum);
        ledNum = _crol_(ledNum, 1);
        delay(100);
    }
}
