LCD时钟温度计C语言程序怎么写?

我这有以前做好的温度测量部分的程序,先给你吧,如果有其他更好的答案的话你也可以采纳,没有的话我这也可以给你做个参考,用的是DS18B20温度传感器。#include<reg52。h>#include<stdio。h>#define uint unsigned int#define uchar unsigned charsbit ds=P1^0;bit flag;uchar count_t0;float f_temp;void delay(uint z){ uint x,y; for(x=z;x>0;x--) for(y=122;y>0;y--);}void init() // 串口初始化{ TMOD=0x21; SCON=0x50; TH0=0x4c; TL0=0x00; TH1=0xf3; TL1=0xf3; EA=1; ET0=1; TR0=1; TR1=1;}void timer0() interrupt 1{ TH0=0x4c; TL0=0x00; if(++count_t0>=20) { count_t0=0; flag=1; }}void dsreset(){ uint i; ds=0; i=103; while(i>0) i--; ds=1; i=4; while(i>0) i--;}bit read_bit(){ uint i; bit dat; ds=0;i++; ds=1;i++;i++; dat=ds; i=8; while(i>0) i--; return dat;}uchar read_byte(){ uchar i,j,dat; dat=0; for(i=1;i<=8;i++) { j=read_bit(); dat=(j<<7)|(dat>>1); } return dat;}void write_byte(uchar dat){ uint i; uchar j; bit testb; for(j=1;j<=8;j++) { testb=dat&0x01; dat=dat>>1; if(testb) { ds=0; i++;i++; ds=1; i=8; while(i>0) i--; } else { ds=0; i=8; while(i>0) i--; ds=1; i++;i++; } }}void begin_change(){ dsreset(); delay(1); write_byte(0xcc); write_byte(0x44);}float get_temp(){ uchar a,b; uint temp; float f_temp; dsreset(); delay(1); write_byte(0xcc); write_byte(0xbe); a=read_byte(); b=read_byte(); temp=b; temp<<=8; temp=temp|a; f_temp=temp*0。0625; temp=f_temp*10+0。5; f_temp=f_temp+0。05; return f_temp;}void main(){ init(); while(1) { if(flag==1) { flag=0; begin_change(); TI=1; printf("The tempeature is %f\n",get_temp()); while(!TI); TI=0; } }} 。希望能够帮助你 ^_^ 也希望能够选为最佳答案!
