单片机温度计报警机制程序 320x240TFT屏幕上显示有温度条，超过设定值会报警蜂鸣...

ID:114350 · 发表于 2016-4-15 10:43

如标题，屏幕上显示有温度条，超过设定温度会报警，就是蜂鸣器会响

部分源码如下（完整版本请下载附件）：

/*===================================================================================================
工程名称： Ex1
功能描述：控制TFT实现温度计的显示，以及使用独立按键控制最高温度、最低温度，并在TFT上显示最高温度最低温度及当前温度值
硬件连接：查看和修改接口定义在NBCTFT.C中,请仔细检查接口连线。
----------------------------------------
| --------TFT控制接线---------- |
| |
| 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; |
| |
| --------电源供电接线--------- |
| GND 接电源负极 |
| VIN 接电源正极(5V) |
|----------------------------------------|
| 如果在NBC开发板上使用，以上线不需用飞 |
| 线连接，直接插接在开发板上的12864接口 |
----------------------------------------
硬件连接：用1位杜邦线将J8_7与J17_18b20连接；
用1位杜邦线将J8_6与J18_BZ连接；
用5位杜邦线将J9_7与J7_s17、J9_6与J7_s18、J9_5与J7_s19、J9_4与J7_s20、J9_3与J7_s21连接；
