ADC0832+LCD1602+DS18B20仿真原理图如下（proteus仿真工程文件可到本帖附件中下载）
单片机源程序如下:
- #include"LCD.H"
- #include"AD0832.H"
- #include"DAC0832.H"
- #include"DS18B20.H"
- unsigned char Serial[64]={0};
- unsigned char dd[]={0};
- unsigned char CTemp[]={0};
- unsigned char code tab[]="0123456789. ";
- unsigned char code T[8]={0x18,0x18,0x0F,0x1F,0x18,0x18,0x1F,0x0F};
- void delayms(int dly)
- {
- int i;
- char j;
- for(i=0;i<dly;i++)
- for(j=0;j<120;j++);
- }
- int main (void)
- {
- unsigned char i=255,v=0,temp=0;
- delayms(600);
- LCD_Init();
- DacInit();
- WriteStringToLcd(0,0,"V1:");
- WriteStringToLcd(7,0,"v");
- WriteStringToLcd(0,1,"Temp:");
- Write_self(T);
- Write_selfString(8,1,0);
- delayms(200);
- WriteToDac0832(255);
- while(1)
- {
- v=ReadAdc0832(0);
- dd[0]=tab[v/51];
- dd[1]=tab[10];
- dd[2]=tab[10*v/51%10];
- dd[3]=tab[100*v/510%10];
- WriteStringToLcd(3,0,dd);
- temp=ReadTempreture(Serial,9);
- if(temp>100)
- {
- CTemp[0]=tab[temp/100];
- CTemp[1]=tab[temp%100/10];
- CTemp[2]=tab[temp%100%10];
- }
- else
- {

- CTemp[1]=tab[temp%10];
- CTemp[2]=tab[11];
- }
- delayms(200);
- WriteStringToLcd(5,1,CTemp);
- }
- return 0;
