void Locatexy(void)          //坐标定位
{
        unsigned char x,y;
        switch (col &0xc0)
        {
                case 0x00:{BusyL();break;}
                case 0x40:{BusyM();break;}
                case 0x80:{BusyR();break;}
    }
        x =col &0x3f | 0x40;
        y=page &0x07 | 0xB8;
这一段是什么意思啊

购买液晶，商家赠送程序。
如果不送程序，就不买。

根本就不用自己写程序。

这个屏分左中右三个区，列 0-63，64-127, 128-191,根据显示的位置，设置列地址，由于列地址只有0-63，所以有3个片选，分别设置3个区域。
