This is the DHT (Humidity-Temperature) sensors STM32 HAL Library

How to use this Library:

• Select “General peripheral Initalizion as a pair of ‘.c/.h’ file per peripheral” on project settings.
• Enable a gpio pin as external interrupt on both Rising and Falling edge.
• Enable a timer as normal mode.
• Include Header and source into your project.
• Config “dhtConf.h”.
• Create your DHT_t struct.
• Put DHT_pinChangeCallBack(your struct) in external callback function.
• Call DHT_init( .. .. .. ).
• Read data by DHT_readData(&temp,&humid)

#include "DHT.h"
DHT_t     am2301;
bool      am2301_ok;
void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)
{
  if(GPIO_Pin == am2301.pin)
  {
    DHT_pinChangeCallBack(&am2301);
  }
}
int main()
{
  DHT_init(&am2301,DHT_Type_AM2301,&htim7,72,AM2301_GPIO_Port,AM2301_Pin); 
  while(1)
  {
    HAL_Delay(5000);
    float t,h;
    am2301_ok = DHT_readData(&am2301,&t,&h);  
  }
}
