12864程序问题请教

ID:51597 · 发表于 2016-1-18 08:44

从网上下载了个无字库12864显示程序，但是但是断电送电后程序不显示，有时候刚下载能显示，再下载进去就不显示，怪了。
#include <reg51.h>
#include <intrins.h>
#define uint unsigned int
#define uchar unsigned char

#define Port P0 //LCD12864数据线

sbit RS=P1^0; // 数据\指令选择
sbit RW=P1^1; // 读\写选择
sbit EN=P1^2; // 读\写使能
sbit cs1=P1^6; // 片选1
sbit cs2=P1^7; // 片选2

主程序中，可以先做些自检，过1－2秒后再进行 InitLCD初始化。LCD刚上电自身还没复位。

不是这个问题，刚下载程序也不显示，液晶早送电了，麻烦给看看程序吧
