你可以参考下面这段代码,同样是T6963C,只是显示区域是240*128, *** 作之前先将LCD复位一次,你对着资料将初始化的寄存器改改就可以了,另外电路和你的不同,所以读状态寄存器和写寄存器的方法不同,你的需要 *** 作P0,P1,P3口模拟读和写.其实T6963C可以直接和MCS51外部总线接口的,时序完全满足要求,下面的代码就是将/CE接P2.7,C/D接P2.0,直接用MOVX指令访问的.#define dis_comand XBYTE[0x7fff]//液晶 *** 作命令地址
#define dis_data XBYTE[0x7ffe]//液晶显示数据地址
#define discommand 1//定义液晶 *** 作的常量
#define disdata0
/*****************************************
