STM32编码器模式测试例程

STM32编码器模式的测试例程，代码中采用TIM2定时器的编码器模式，在主程序中利用延时函数监测单位时间内的脉冲数，并根据脉冲数计算速度。程序中不包含电机输出控制和PID调速。

#include “beep.h“


	   

//初始化PE8为输出口.并使能这个口的时钟		    
//蜂鸣器初始化
void BEEP_Init（void）
{
 
 GPIO_InitTypeDef  GPIO_InitStructure;
 	
 RCC_APB2PeriphClockCmd（RCC_APB2Periph_GPIOE ENABLE）;	 //使能GPIOE端口时钟
 
 GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2;				 //BEEP-->PE.4 端口配置
 GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; 		 //推挽输出
 GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;	 //速度为50MHz
 GPIO_Init（GPIOE &GPIO_InitStructure）;	 //根据参数初始化GPIOE.4
 
 GPIO_ResetBits（GPIOEGPIO_Pin_2）;//输出0，关闭蜂鸣器输出


}
void BEEP_Ring（uint16_t time） //蜂鸣器短鸣
{	
	GPIO_SetBits（GPIOEGPIO_Pin_2）;  
	delay_ms（time）;
	GPIO_ResetBits（GPIOEGPIO_Pin_2）;	
}
