/********************************************************************************************
* 文 件 名：test1.c
* 功 能：LCM12864液晶模块驱动。
* 硬件条件：1.CPU型号：AT89S52
* 2.晶振：12.000MHz
* 4.LCM12864与AT89S52的连接如下：
*
* LCM12864 AT89S52 备 注
* ==================================================================================
* RS P2.7 0：写指令或读状态； 1：数据操作
* R/W P2.6 0：进行写操作； 1：进行读操作
* E P2.5 读写脉冲：在E下降沿，数据被锁存（写）入KS0108
* 在E高电平期间，数据被读出。
* DB0 P0.0 数据线0
* DB1 P0.1 数据线1
* DB2 P0.2 数据线2
* DB3 P0.3 数据线3
* DB4 P0.4 数据线4
* DB5 P0.5 数据线5
* DB6 P0.6 数据线6
* DB7 P0.7 数据线7
* CS1 P2.4 高电平选通，选中左半屏。
* CS2 P2.3 高电平选通，选中右半屏。
* RESET P2.2 低电平有效，复位信号有效时，关闭液晶显示，使显示
* 起始行为0，该引脚可与MCU相连，由MCU控制；也可以
* 直接接VDD，使之不起作用。
* ==================================================================================
*
*
* 说 明：用户可根据实际情况，改变上述的连接关系。默认背景灯常开，必要的话可加电路
* 实现控制点亮。
