STM32F103C8T6开启TIM1定时器代码

以下是STM32F103C8T6开启TIM1定时器的示例代码：

#include "stm32f10x.h"

void TIM1_Configuration(void)
{
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;

    /* 启用TIM1的时钟 */
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1, ENABLE);

    /* 配置TIM1的时基参数 */
    TIM_TimeBaseStructure.TIM_Period = 999;  // 定时器周期
    TIM_TimeBaseStructure.TIM_Prescaler = 71;  // 定时器预分频
    TIM_TimeBaseStructure.TIM_ClockDivision = 0;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);

    /* 启用TIM1的中断 */
    NVIC_InitTypeDef NVIC_InitStructure;
    NVIC_InitStructure.NVIC_IRQChannel = TIM1_UP_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);

    /* 启用TIM1的更新中断 */
    TIM_ITConfig(TIM1, TIM_IT_Update, ENABLE);

    /* 启动TIM1计数 */
    TIM_Cmd(TIM1, ENABLE);
}

int main(void)
{
    /* 初始化时钟 */
    RCC_DeInit();
    SystemInit();

    /* 配置TIM1 */
    TIM1_Configuration();

    while (1)
    {
        /* 程序主循环 */
    }
}

void TIM1_UP_IRQHandler(void)
{
    if (TIM_GetITStatus(TIM1, TIM_IT_Update) != RESET)
    {
        /* 处理TIM1中断 */
        TIM_ClearITPendingBit(TIM1, TIM_IT_Update);
    }
}

该代码利用TIM1的时基参数进行定时，并启用了TIM1的中断。在实际应用中，可以在`TIM1_UP_IRQHandler`函数中处理定时器中断，并进行相应的操作。
