【ESK32-30519 + ESK32-21001测评】5、基于HT32F54253的人体额温报警系统
本工程是这次评测活动过程的单独评测结果的综合，利用ESK32-30519 + ESK32-21001硬件资源组成了基于HT32F54253的人体额温报警系统。
硬件资源:
软件资源:
BFTM定时器
LEDC数码管代码库
TKL触摸按键代码库
Buzzer蜂鸣器代码
DVB_LED代码库
USART代码库
实现功能：人体红外测温报警系统。
通过USART串口读取温度传感器数据；
4位LED数码管显示人体温度值。两位整数+1位小数，平时末位数码管显示摄氏度“c”，进入设置模式时末位数码管显示“-”；
4只触摸按键用于设定报警温度的阈值：PD1进入设置模式，PD2退出设置模式，PD3增加报警阈值，PD4减少报警阈值；
当超温时，蜂鸣器声响报警，红色LED亮起报警。
HT32F54235代码库的特点：
1、HT32F54235的LEDC功能使得用户无需关注底层函数就能方便驱动LED数码管；
2、触摸按键克服了普通触点按键寿命短的毛病。
3、蜂鸣器的代码调用非常简单，音频的频率、时长、占空比、次数等在函数调用时一目了然，简单方便。
