12864c.c

12864液晶驱动文件!包含5个文件!非常的有用!为C51的开发!

小弟我用一个较便宜的仿真器仿12864的LCD模块，接线是最简单的那种：
P0口带上拉接数据线
W/R接地
REST接VCC
DI=P1^0;    写数据或写指令
EN=P1^1;    //使能
CS1=P1^2;    //左64列片选
CS2=P1^3;    //右64列片选
Back_light=P1^4;//背光控制
现在连最简单的写全0，写全1，也不能按照我的意图显示，很受打击，请各位DX指点迷津呀
我的程序如下：
#include<reg51.h>
#define uchar unsigned char
#define uint unsigned int
sbit DI=P1^0;    //写数据或写指令
sbit EN=P1^1;    //使能
sbit CS1=P1^2;    //左64列片选
sbit CS2=P1^3;    //右64列片选
sbit Back_light=P1^4;        //背光开关
bit bf;
Lcd_WD(uchar ddata);    //写数据
Lcd_dis(uchar inst);    //开显示
Lcd_set_x(uchar x);    //设置页地址
Lcd_set_y(uchar i);    //设Y地址
Lcd_clr();    //清屏
dis_welcom();//显示welcom!
//**welcom!128x64
