STM32 - vibration sensor control relay on

STM32—— The vibration sensor controls the relay to turn on the light

Environmental Overview ：

Windows10 pro

MDK—Lite 5.25

Hardware list ：

1、 Relay

2、USB The lamp

3、SW-1801P Vibration sensors

4、STM32f103c8t6

Be careful ：

stay User Folder create related folders and xx.c and xx.h file , Include related header files ,

Some basic operations have been written in previous articles

The experimental steps ：

1、 Can make APB2 Medium GPIOA The clock turns on

Where to find relevant functions , It is also written in the previous article

//1、 Can make APB2 Medium GPIOA The clock turns on 
	RCC_APB2PeriphClockCmd( RCC_APB2Periph_GPIOA, ENABLE);

​

2、 To configure GPIOA Structural content

Before that , In defining structures

GPIO_InitTypeDef Shake_GPIO_Init;

// Drop down input 
Shake_GPIO_Init.GPIO_Mode   = GPIO_Mode_IPD;
// Set pin to A1
Shake_GPIO_Init.GPIO_Pin    = GPIO_Pin_1;
Shake_GPIO_Init.GPIO_Speed  = GPIO_Speed_10MHz;

3、 initialization

GPIO_Init(GPIOA,&Shake_GPIO_Init);

Code ：

#include "stm32f10x.h"
#include "shake.h"

void Shake_Init()
{
    
	// Defining structure 
	GPIO_InitTypeDef Shake_GPIO_Init;
	//1、 Can make APB2 Medium GPIOA The clock turns on 
	RCC_APB2PeriphClockCmd( RCC_APB2Periph_GPIOA, ENABLE);

	//2、 To configure GPIOA Structural content 
	// Drop down input 
	Shake_GPIO_Init.GPIO_Mode   = GPIO_Mode_IPD;
	// Set pin to A1
	Shake_GPIO_Init.GPIO_Pin    = GPIO_Pin_1;
	Shake_GPIO_Init.GPIO_Speed  = GPIO_Speed_10MHz;
	GPIO_Init(GPIOA,&Shake_GPIO_Init);

	
}

main.c file

By reading the level of the sensor , To judge and control the light on

If the reading sensor is low , Then turn on the light

Code ：

#include "stm32f10x.h"
#include "led.h"
#include "Relay.h"
#include "Shake.h"
int main(void)
{
     
	LED_Init();// The lamp 
	Relay_Init();// Relay 
	Shake_Init();// Vibration sensors 
	
	GPIO_SetBits(GPIOA, GPIO_Pin_3);// It's pins 3j Relay high level —— Turn off the lights 
	
	while(1){
    
		
		//1、 By reading the level of the sensor , To judge and control the light on 
		//
		if(GPIO_ReadOutputDataBit(GPIOA,GPIO_Pin_1 == 0)){
    
			// If the reading sensor is low , Then turn on the light 
			GPIO_ResetBits(GPIOA, GPIO_Pin_3);// turn on the light 
			delayTime(1000);// Time delay 
			GPIO_SetBits(GPIOA, GPIO_Pin_3);// Turn off the lights 
		}else{
    
			GPIO_SetBits(GPIOA, GPIO_Pin_3);// Turn off the lights 
		}
	}

}

summary ：

Practice over and over again , Remember the code , Remember the principle , More practice .
