波形,就是不断刷新的图片,12864的串行液晶,楼主用的是不是ST7294的主控? ... uchar re_byte(void)
{
uchar re=0,i;
P6DIR = 0x00;
for(i=0;i<8;i++)
{
LCD_CLK_Low;
delay_ms(10);
if(P6IN&0x10)
{
re = re| 0x01;
delay_ms(2);
re <<= 1;
}
else
{
re = re| 0x00;
delay_ms(2);
re <<= 1;
}
LCD_CLK_High; //上升沿触发发送
delay_ms(10);
LCD_CLK_Low;delay_ms(2);
}
return re;
}
unsigned char ReadByte(void)
{
unsigned char byReturnValue,a ;
delay_ms(1);
Send_Byte(0xfe); //11111,RW(1),RS(1),0
delay_ms(1);
byReturnValue=re_byte() ;
delay_ms(1);
a=re_byte()>>4;
byReturnValue = byReturnValue|a;
return byReturnValue ;
}
