标题: dht11温湿度检测器制作 5001显示 带单片机源码
做了一个基于dht11和5001显示模块的温湿度检测器


单片机源程序如下:

1. #include <reg52.h>
   
2. #include"dht11.h"
   
3. sbit    res = P2^0;  //复位,0复位
   
4. sbit    sce = P2^1;  //片选
   
5. sbit    dc  = P2^2;  //1写数据，0写指令
   
6. sbit    sdin = P2^3;  //数据
   
7. sbit    sclk = P2^4;  //时钟
   
8. 
   
9. unsigned char code shuzi[]={
