1、单片机晶振为11.0592MHz，LCD液晶显示用Nokia5110，当然用LCD1602也可以，只是要把显示部分的函数换了，温湿度传感器用DHT11。LCD、DHT11、以及蜂鸣器用到的引脚在PUBLIC.H中有定义。只要把相关文件添加进工程即可WKC.C如下#defineucharunsignedchar#defineuintunsignedintuchartimer0_count;//主函数入口voidmain(){TMOD=0x01;TH0=0x4B;TL0=0xFF;ET0=1;EA=1;TR0=1;LCD_init()

2、;//初始化LCD模块while(1);}//定时器0中断服务函数voidtimer0()interrupt1{TH0=0x4B;TL0=0xFF;timer0_count++;if(timer0_count==20){Scan_DHT11();timer0_count=0;}}LCD5110.c如下#include#include"PUBLIC.h"#defineucharunsignedchar#defineuintunsignedint//字符6X12,阳码，列行式，逆向，十六进制unsignedcharc
