如標(biāo)題，屏幕上顯示有溫度條，超過設(shè)定溫度會報警，就是蜂鳴器會響

部分源碼如下（完整版本請下載附件）：

/*===================================================================================================
工程名稱： Ex1
功能描述：控制TFT實現(xiàn)溫度計的顯示，以及使用獨立按鍵控制最高溫度、最低溫度，并在TFT上顯示最高溫度最低溫度及當(dāng)前溫度值
硬件連接：查看和修改接口定義在NBCTFT.C中,請仔細檢查接口連線。
----------------------------------------
| --------TFT控制接線---------- |
| |
| D10~D17 接 P0 |
| RS 接 P2^5; |
| RW 接 P2^4; |
| RD 接 P2^3; |
| CS 接 P2^2; |
| RES 接 P2^1; |
| |
| LE 接 P2^0; |
| |
| --------電源供電接線--------- |
| GND 接電源負極 |
| VIN 接電源正極(5V) |
|----------------------------------------|
| 如果在NBC開發(fā)板上使用，以上線不需用飛 |
| 線連接，直接插接在開發(fā)板上的12864接口 |
----------------------------------------
硬件連接：用1位杜邦線將J8_7與J17_18b20連接；
用1位杜邦線將J8_6與J18_BZ連接；
用5位杜邦線將J9_7與J7_s17、J9_6與J7_s18、J9_5與J7_s19、J9_4與J7_s20、J9_3與J7_s21連接；
