標(biāo)題: 熱敏電阻溫度計(jì)仿真加單片機(jī)源碼
熱敏電阻溫度計(jì)仿真原理圖：


單片機(jī)源程序如下:
  1. #include<reg52.h>
  2. #define uchar unsigned char
  3. #define uint unsigned int

  5. //
  6. unsigned char code dispbitcode[]=
  7. {0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f};
  8. //
  9. //

  11. unsigned char code LEDcode[]=
  12. {0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x00,0x40};
  13. //
  14. //
  15. unsigned char dispbuf[8]={10,10,10,10,10,10,0,0};
  16. //
  17. unsigned char dispcount;
  18. unsigned int uiResult;
  19. bit sflag;
  20. sbit START=P3^1;
  21. sbit OE=P3^0;
  22. sbit EOC=P3^2;
  23. sbit P17=P1^7;
  24. //

  26. void delay(uint z)           //延時(shí)函數(shù)，約1ms
  27. {
  28.         uint x,y;
  29.         for(x=z;x>0;x--)
  30.                 for(y=110;y>0;y--);
  31. }
  32. void Display()
  33. {for(dispcount=0;dispcount<5;dispcount++)
  34. {P2=0xff;
  35. P1=LEDcode[dispbuf[dispcount]];
  36. if(dispcount==3)
  37. {P17=1;}
  38. P2=dispbitcode[dispcount];
  39. delay(1);
  40. P2=0xff;
  41. }
  42. }
  43. //
  44. void ADC0809()
  45. {
  46.         unsigned char i;
  47.         unsigned long y;

  49. //        START=0;
  50.         START=1;
  51.         START=0;
  52. P0=0Xff;
  53. //EOC=1;
  54. while(EOC==0);
  55. OE=1;
  56. uiResult=P0;
  57. OE=0;
  58. y=uiResult;
  59. uiResult=(y*2516)/128;
  60. if(uiResult<2732)
  61. { uiResult=2732-uiResult;sflag=1;}
  62. else
  63. { uiResult=uiResult-2732;sflag=0;}
  64. i=4;
  65. dispbuf[1]=0;
  66. dispbuf[2]=0;
  67. dispbuf[3]=0;
  68. dispbuf[4]=0;
  69. if(sflag==1)
  70. { dispbuf[0]=11;}
  71. else
  72. { dispbuf[0]=10;}
  73. dispbuf[5]=10;
  74. dispbuf[6]=10;
  75. dispbuf[7]=10;
  76. while(uiResult/10)
  77. {dispbuf[i]=uiResult%10;
  78. uiResult=uiResult/10;
  79. i--;
  80. }
  81. dispbuf[i]=uiResult;
  82. }
  83. //
