lcd 驱动程序 很好的呦 可以参考一下

void LcdWd(unsigned char DAT)
{
 unsigned char temp1,temp2;
 LOOP1:DDRT=0xff;
       DDRK=0xff;
       PTT_PTT0=0;
       PTT_PTT1=1;
       PORTK=0xff;
       PTT_PTT2=1;
       DDRK=0x00;
       temp1=PORTK;
       PTT_PTT2=0;
       PTT_PTT2=1;
       PTT_PTT2=0;
       temp1&=0x08;
       if(temp1==0x08)
       goto LOOP1;
       PTT_PTT0=1;
       PTT_PTT1=0;
       DDRK=0xff;
       temp2=DAT>>4;
       PORTK=temp2;
       PTT_PTT2=1;
       PTT_PTT2=0;
       PORTK=DAT;
       PTT_PTT2=1;
       PTT_PTT2=0;
