請老師發(fā)圖上來看看、我參考下！有沒什么地方不對的。
#include<reg52.h>
sbit HC595_DS = P3^0;
sbit HC595_STCP = P3^1;
sbit HC595_SHCP = P3^2;
sbit HC595_OE = P3^7;
void HC595_WriteByte(unsigned char value)
{
unsigned char i;
for(i=0;i<8;i++)
{
HC595_SHCP = 0;
HC595_DS = value&(0x80>>i);
HC595_SHCP = 1;
}
}
void Lattice_WriteData(unsigned char *buffer,unsigned char value,unsigned char value1)
{
while(*buffer)//列掃描
{
HC595_WriteByte(*buffer++);
}
HC595_WriteByte(value);//行數據低八位
HC595_WriteByte(value1);//行數據高八位
HC595_STCP = 0;
HC595_STCP = 1;
}
unsigned char buffer[8]={0x01,0,0,0,0,0,0,0};//64列
void main()
{
HC595_OE = 0;
HC595_OE = 1;
//假設行低電平有效，列高電平有效，顯示效果為第一行，第一列坐標為（0，0）的像素點亮，其他均不亮
Lattice_WriteData(buffer,0xfe,0xff);
while(1);
}
還請老師指點下。
