本次实验所用硬件为：STM32F407ZGT6小黑板+DHT11温湿度模块

任务一：直接是库中的BSP

任务二：报警模块采用LED的亮暗来实现

#include <led_alert.h>
      #include <board.h>
     #define LED0_PIN    GET_PIN(F, 9)

void led_init()
{
   rt_pin_mode(LED0_PIN, PIN_MODE_OUTPUT);
   
}

void led_on()
{
  rt_kprintf("turn on led!<br>");
   rt_pin_write(LED0_PIN, PIN_LOW);
}

void led_off()
{
   rt_kprintf("turn off led!<br>");
    rt_pin_write(LED0_PIN, PIN_HIGH);
}

void led_blink()
{
        rt_pin_write(LED0_PIN, PIN_HIGH);
        rt_thread_mdelay(200);
        rt_pin_write(LED0_PIN, PIN_LOW);
        rt_thread_mdelay(200);
}
任务三：按键模块

#include <board.h>
   #include <key.h>
   #include <led_alert.h>
   #define KEY0_PIN    GET_PIN(E, 4) 
   #define LED0_PIN    GET_PIN(F, 9)

void key_init(void)
{
  rt_pin_mode(KEY0_PIN, PIN_MODE_INPUT_PULLUP);
}

void key_cb(void)
{
    rt_kprintf("turn on led!<br>");
if(rt_pin_read(KEY0_PIN)==1)
     rt_pin_write(LED0_PIN, PIN_LOW);
else if(rt_pin_read(KEY0_PIN)==0)
    rt_pin_write(LED0_PIN, PIN_HIGH);
}
    
 void key_sample(void)
{
    rt_pin_mode(KEY0_PIN, PIN_MODE_INPUT_PULLUP);
    rt_pin_attach_irq(KEY0_PIN, PIN_IRQ_MODE_FALLING, key_cb, RT_NULL);
    rt_pin_irq_enable(KEY0_PIN, PIN_IRQ_ENABLE);
}
MSH_CMD_EXPORT(key_sample, key sample)

任务四：温湿度传感器的驱动

依据源代码完成：在手动添加DHT11文件后，缺少“sensor.h”文件，在询问同学后了解到应在原路径下面打开ENV,执行scons --target=mdk5命令，且在main.c文件里面添加了#define PKG_USING_DHT11，程序最终成功。

这家伙很懒，什么也没写！
