FG12864E出了点儿问题

从网上买的12864显示屏，不知道怎么了就是显示不了，程序在PROTUES里面试了试可以用，引脚都改了，电位器改完了只是显得大或者小，就是不显示完全。能不能问下大虾们有没有遇到过类似的情况，能为小弟指点迷津。

我知道附上程序，很少人会看，但是小弟为此真的看了2天了还是毫无进展，才在这里咨询大家，希望赏脸看下，其实也就是读写模块，还有这个程序比较清晰，我一直在PROTUES里用它去进行修改
#include<reg52.h>
#define uchar unsigned char
#define lcd P0

sbit cs1 = P2^1; //换位了cs1和cs2
sbit cs2 = P2^2;
sbit rw = P2^5;
sbit rs = P2^4;
sbit e= P2^6;
sbit busy=ACC^7; //按列取，且字符是倒着的，第二排是第一排的，
