显示原理:

74HC595(串转并)模块

OE使能,0有效

VCC串型

代码:

void WriteByte(unsigned char Byte)
{
	unsigned char i;
	for(i=0;i<8;i++)
	{
		SER=Byte&(0x80>>i);
		SCK=1;//上升沿移位
		SCK=0;
	}
	RCK=1;
	RCK=0;
}

消影过程:

void ShowColumn(unsigned char Column,Data)
{
	WriteByte(Data);
	P0=~(0x80>>Column);
	Delay(1);//消影
	P0=0xFF;
}

完整代码:

#include <REGX52.H>
sbit RCK=P3^5;
sbit SCK=P3^6;
sbit SER=P3^4;
void Delay(unsigned int xms)
{
	unsigned char i, j;
	while(xms--)
	{
		i = 2;
		j = 239;
		do
		{
			while (--j);
		} while (--i);
	}
}

unsigned char Animation[]={
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
0xFF,0x08,0x08,0x08,0xFF,0x00,0x0E,
