这是12864的程序，这是调子程序的语句，看子程序的名是Disp_HZ(0x80,line1,1)，应该是显示汉字的语句，调用时带有3个参数，第一个0x80，应该是显示行在第一行，第二个line1，应该是先定义的一个汉字的字符串，就是要显示的汉字，第三个数应该是表示左屏。有些12864屏是分左右屏显示的。具体的这3个参数是不是这些意义，要看具体的子程序就知道了。

这使msp430单片机的程序，只要在主函数中调用函数，就是调用这个函数Int_char(tmp);每一次循环调用一次，这样可以实时显示这个变化温度数值
LCD12864_gotoXY(2,4);
LCD12864_sendstr(" ");
LCD12864_gotoXY(1,0); //第1行，第1列显示
LCD12864_sendstr("正在检测");
LCD12864_gotoXY(2,0); //第2行，第1列显示
LCD12864_sendstr("距离是：");
Int_char(tmp);
