风扇的使用代码：

#include "fan.h"
void hal_fan_init()
{
	/******RCC章节初始化**********/
	//1、使能GPIOE组
	RCC->MP_AHB4ENSETR |=0x1 <<4;
	//2、使能TIM组相关控制器
	RCC->MP_APB2ENSETR |=0x1;
	/******GPIO章节初始化*******/
	GPIOE->MODER &=(~(0x3 << 18));
	GPIOE->MODER |=(0x2 << 18);
	GPIOE->AFRH &= (~(0xf << 4));
	GPIOE->AFRH |= (0x1 << 4);
	/******TIM4章节初始化*******/
	TIM1->BDTR	|=0x1 << 15;
	TIM1->PSC |=208;
	
	TIM1->ARR |=1000;
	
	TIM1->CCR1 |=700;


	TIM1->CCMR1 &=0x0 << 16;
	TIM1->CCMR1 &=(~(0x7 << 4));
	TIM1->CCMR1 |=0x6 << 4;
	TIM1->CCMR1 |=0x1 << 3;
	TIM1->CCMR1 &=(~(0x3 ));
	

	TIM1->CCER &=(~(0x1<<3));
	TIM1->CCER |=0x1<<1;
	TIM1->CCER |=0x1;

	TIM1->CR1 &=(~(0x0 << 5));
	TIM1->CR1 |=0x1 << 4;
	TIM1->CR1 |=0x1 ;
