uchar x1,x2,data;
    uint address;
x1=x/8;
x2=x%8;
    address=(y&0x7F)*LCDCOLUMN+x1+0x0800;
   data=0xf0+7-x2;
data=dat|0x08;

WrTwoParCmd((uchar)(address),(uchar)(address>>8),ADPSET);  //Set Display Ram Address
WriteCmd(data) //写命令

用位指令应该可以了

void WrPoint(uchar x,uchar y)
{
uchar x1,x2,data;

void WrPoint(uchar x,uchar y)
{
      uchar x1,x2,data;
      uint address;
      x1=x/8;
      x2=x%8;
      address=(y&0x7F)*LCDCOLUMN+x1+0x0800;
      WrTwoParCmd((uchar)(address),(uchar)(address>>8),ADPSET);  //Set Display Ram Address
data=ReadData();//读数据

WriteCmd(0xC5);

      WrOneParCmd(data|(0x80>>x2),0xC4);
      }
}

这样也不行

这个试了不行

{

    address=(y&0x7F)*LCDCOLUMN+x1+0x0800;

WriteCmd(0xC5);
data=ReadData();//读数据

WrOneParCmd(data|(0x80>>x2),0xC4);
    }
}
