我感覺也是
writeComm(0x80+0x40);
    writeString(table, 7);

指定顯示位置呀

writeComm(0x80+0x40);
    writeString(table, 7);
也可以，你試試

uchar code addr[]={0x00,0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x0a,0x0b,0x0c,0x0d,0x0e,0x0f,//第一行顯示位置
                   0x40,0x41,0x42,0x43,0x44,0x45,0x46,0x47,0x48,0x49,0x4a,0x4b,0x4c,0x4d,0x4e,0x4f//第二行顯示位置
                                   };


void zuobiao(uchar x,uchar y,uchar *s)
{
        uchar dizhi;
        dizhi=addr[16*x+y];
    Cmd(dizhi | 0x80);
        while(*s>0)
         {
              Data(*s);
                  s++;
         }
}

zuobiao(1,0,table)；
