proteus 仿真问题..

时间：10-02 整理：3721RD 点击：

求大神看看。

求别沉

代码是没问题的..

只是个警告而已，应该不影响。后面不是有个蓝色的问号吗，点开看看提示。

P05没有真的连上，虽然你放了网络，但是可能没对准。

打开了，但是看不懂，里面和其他的P01好像没什么区别.

有了的，这个图我画了好几次了，都是一样包括我用线去对接，还是一样。

搜索
logic contention detected on net
你这可能是代码有问题，端口冲突了。

..这个是我加载了代码之后的提示。代码是我也换了老师提供试了一下，还是一样的问题，老师说是硬件问题。我的其他同学是没有出现这个问题，但是屏幕还是没什么反应，也没有什么提示，

#include "reg51.h"
sbit CS1 = P2^6; //右屏片选
sbit CS2 = P2^5; //左屏片选
sbit RS = P2^3; //1为数据，0为指令
sbit RW = P2^2; //1为读操作，0为写操作
sbit EN = P2^1; //读写使能
sbit RST = P2^4; //复位，低电平有效
sbit busy = P0^7;
#define DataPort P0 //定义数据端口

搞定了，是代码问题，是检查忙那里的问题，而且还有端口定义位置反了...

应该是是状态判断那里卡住了..
