51单片机1602液晶显示代码在keil中没有错误，但在proteus中运行无结果？
这是你要的效果吧，程序帮你修改了，你对比看一下，满意请采纳 #include #define uchar unsigned char #define uint unsigned int sbit rs=P2^0; //根据你实际修改 sbit rw=P2^1; //根据你实际修改 sbit e=P2^2; //根据你实际修改 uchar table1[]="qqqqqqqqq"; uchar table2[]="qqqqqqqqq"; void delay_50us(uint t)//延迟函数； { uchar j;for(;t>0;t--)for(j=6245;j>0;j--);} void write_com(uchar com){e=0;rs=0;rw=0;P0=com; //根据你实际修改delay_50us(10);e=1;delay_50us(20);e=0;}void write_data(uchar dat){e=0;rs=1;rw=0; //根据你实际修改P0=dat;delay_50us(10);e=1;delay_50us(20);e=0;}void init(void){delay_50us(300);write_com(0x38);delay_50us(100);write_com(0x38);delay_50us(100);write_com(0x38);write_com(0x38);write_com(0x08);write_com(0x01);write_com(0x06);write_com(0x0c);}void main(){uchar j;init();write_com(0x80);for(j=0;j<9;j++){write_data(table1[j]);delay_50us(10);}write_com(0x80+0x40); //根据你实际字符写屏for(j=0;j<9;j++){write_data(table2[j]); //根据你实际字符写屏delay_50us(10);} while(1) //你原来没有的 { }}
proteus仿真是1602液晶不显示字符 求高人指点
绝b是程序的问题吧，程序发过来我看看，后者你先认真参考一下时序，单片机难就难在这个时序上面。电路图没错啊，我照你的画了，刚好我这里有以前做实验的程序，试了一下没问题，不过我的程序里面有关于中断的东东，电路有点不一样，但我是试了你的电路的，说明电路没问题。程序如下，你拷贝过去试试，看看行不行。#include#define uchar unsigned char#define uint unsigned intsbit lcdrs=P3^4;sbit lcden=P3^5;uchar code table[]=" ELECFANS ";uchar code table1[]="MADE BY PENG LEI";uchar num;void delay(uchar);void Init();void write_com(uchar);void write_data(uchar);void main(){Init();delay(100);EA=1;EX0=1;EX1=1;while(1);}void Init(){lcden=0;write_com(0x38);write_com(0x0f);write_com(0x06);write_com(0x01);write_com(0x80+0x1);}void write_com(uchar com){lcdrs=0;P2=com;delay(5);lcden=1;delay(5);lcden=0;}void delay(uchar z){uchar i,j;for(i=z;i>0;i--){for(j=100;j>0;j--);}}void write_data(uchar Data){lcdrs=1;P2=Data;delay(5);lcden=1;delay(5);lcden=0;}void int0() interrupt 0{for(num=0;num<16;num++){write_data(table[num]);delay(500);}write_com(2);write_com(0x80+0x40);for(num=0;num<16;num++){write_data(table1[num]);delay(500);}}void int1() interrupt 2{write_com(1);}
