標(biāo)題: 關(guān)于單片機(jī)溫度控制系統(tǒng)的課設(shè) 有源代碼和仿真文件
做了兩周的課程設(shè)計(jì)，是關(guān)于溫度控制系統(tǒng)的
附件里有源代碼，和仿真文件，
第一次做，也在圖書館里查詢了一些資料
解決了一些問題
仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）


單片機(jī)源程序如下:

  5. unsigned char code Error[]={"Error!Check!"};
  6. unsigned char code D2[]={"Motor: "};
  7. unsigned char code TS1[]={"COOL DOWN!"};
  8. unsigned char code TS2[]={" STOP! "};
  9. unsigned char code TS3[]={"HOT UP!"};
