求大神帮助，adc0804转换电压在12864上显示的仿真 [复制链接]

//测出的电压经0804转换后在12864上显示

#include

#define uchar unsigned char
#define uint unsigned int
#define port P1 //DB0~DB7数据口
sbit e=P2^0;//使能
sbit rw=P2^1;//读写
sbit rs=P2^2;//数据/命令
sbit cs2=P2^3;//片选
sbit cs1=P2^4;
sbit busy=P1^7;//检测忙




#define date  P0
sbit cs=P2^5;    //片选信号，控制芯片的启动，低电平有效
sbit rd=P2^6;   //读数据控制，低电平有效
sbit rw1=P2^7;  //AD转换启动控制，上升沿有效
sbit intr=P3^3; //AD转换结束输出低电平
