C++ (Cpp) DHT11_IO_OUT Examples

Example #1

uint8_t DHT11_Init(void)
{	 
  DHT11_IO_OUT();
  
  DHT11_Rst();

} 

Example #2

File: DHT11.c Project: wangeshen/MICO

//Reset DHT11
void DHT11_Rst(void)	   
{                 
  DHT11_IO_OUT(); 											//SET OUTPUT
  DHT11_DATA_Clr(); 											//GPIOA.0=0
  Delay_ms(20);    											//Pull down Least 18ms
  DHT11_DATA_Set(); 											//GPIOA.0=1 
  Delay_us(30);     										//Pull up 20~40us
}
