开发者成长激励计划-基于TencentOS Tiny 的加热不燃烧烟具温度检测设备

   我们在开发加热不燃烧烟具的过程中，需要吧烟具内部的温度加到一个比较高的温度（200-300摄氏度），烟具内部本身有测温器件，但是不能保证烟具自己测试的温度就是准确的，所以就需要一个外部也要增加设备来辅助测试一下，并且把整个加热过程中的温度变化画出曲线，有助于对整个设备的研究。所以我们这次开发所用的硬件除了赤兔CH32V307开发板以外，还增加一个NTC的检测电路。如下图所示：

#include "debug.h"
#include "tos_k.h"
#include "lcd.h"
#include "lcd_init.h"
#include "user_read_temperature.h"
#define M_COUNT_OF(Obj)         (sizeof(Obj) / sizeof(Obj[0]))//总长度除以个体长度等于个数
