; //液晶显示的时候用到LCD_SHOW()就可以了，不过开SPCR = 0x50  使用后关SPCR = 0x54;
; //液晶的尺寸是256*192的. 
; //void LCDSHOW(UINT8 page,UINT8 m,UINT8 n,UINT8 date)
; //page 为0 2 4 8 10对应的是行
; //m 对应的是 0x10  -- 0x17 每一行对应的数据的开始地址
; //n 对应的是 两个字节的数据中的一个 一个汉字是32*32 //n==0的时候显示前半个数据.n=8对应的是后半个数据
; //data 对应的是显示的数据，在显示的时候用的是查表的方法。
