请帮我写一份stm32f407TIM8定时中断配置代码

好的，以下是stm32f407TIM8定时中断配置代码：

#include "stm32f4xx.h"

void TIM8_IRQHandler(void)
{
    if (TIM_GetITStatus(TIM8, TIM_IT_Update) != RESET)
    {
        // 中断处理代码
        TIM_ClearITPendingBit(TIM8, TIM_IT_Update);
    }
}

void TIM8_Configuration(void)
{
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    NVIC_InitTypeDef NVIC_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM8, ENABLE);

    TIM_TimeBaseStructure.TIM_Period = 1000 - 1; // 定时器周期为1ms
    TIM_TimeBaseStructure.TIM_Prescaler = 84 - 1; // 定时器分频系数为84
    TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM8, &TIM_TimeBaseStructure);

    TIM_ITConfig(TIM8, TIM_IT_Update, ENABLE);

    NVIC_InitStructure.NVIC_IRQChannel = TIM8_UP_TIM13_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);

    TIM_Cmd(TIM8, ENABLE);
}

希望对你有所帮助！
