求单片机程序关于温湿度。传感器采用DHT11，按键四个可以设置温湿度的上下限，

显示用lcd1602，超限报警

#include

#include

#define uchar unsigned char

#define uint unsigned int

typedef unsigned char unint8; //unint8 代替undigned char

性

typedef unsigned char unint16;

unsigned char str1[]={" "};

unsigned char str2[]={" "};

unsigned char code dis1[] = {" Xh RH: "}; //定义数组

unsigned char code dis2[] = {" DO T: "};

sbit buz=P1^0;

提高可移植

sbit TRH = P1^7;//温湿度传感器DHT11数据接入

sbit LCD_RS = P1^1;

sbit LCD_RW = P1^2;

sbit LCD_EN = P1^3;

unint8 TH_data,TL_data,RH_data,RL_data,CK_data;

unint8 TH_temp,TL_temp,RH_temp,RL_temp,CK_temp;

unint8 com_data,untemp,temp;

unint8 respond;

void initcom()

{

TMOD=0x20;

TH1=0xfd;

TL1=0xfd;
