写一个用stm32f103c8t6tim1接收编码器数据的程序

以下是一个使用STM32F103C8T6的TIM1定时器接收编码器数据的示例程序：

#include "stm32f10x.h"

void TIM1_Configuration(void);
void GPIO_Configuration(void);

int main(void)
{
    GPIO_Configuration();
    TIM1_Configuration();

    while (1)
    {
        // 在这里可以进行其他操作
    }
}

void TIM1_Configuration(void)
{
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    TIM_ICInitTypeDef TIM_ICInitStructure;
    GPIO_InitTypeDef GPIO_InitStructure;
    NVIC_InitTypeDef NVIC_InitStructure;

    // 使能TIM1和GPIOA的时钟
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1 | RCC_APB2Periph_GPIOA, ENABLE);

    // 配置GPIO引脚
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8 | GPIO_Pin_9;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // 配置定时器基本参数
    TIM_TimeBaseStructure.TIM_Period = 0xFFFF;
    TIM_TimeBaseStructure.TIM_Prescaler = 0;
    TIM_TimeBaseStructure.TIM_ClockDivision = 0;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);

    // 配置编码器接口模式
    TIM_ICStructInit(&TIM_ICInitStructure);
    TIM_ICInitStructure.TIM_Channel = TIM_Channel_1;
    TIM_ICInitStructure.TIM_ICPolarity = TIM_ICPolarity_Rising;
    TIM_ICInitStructure.TIM_ICSelection = TIM_ICSelection_DirectTI;
    TIM_ICInitStructure.TIM_ICPrescaler = TIM_ICPSC_DIV1;
    TIM_ICInitStructure.TIM_ICFilter = 0x0;
    TIM_ICInit(TIM1, &TIM_ICInitStructure);

    // 配置编码器接口模式
    TIM_ICStructInit(&TIM_ICInitStructure);
    TIM_ICInitStructure.TIM_Channel = TIM_Channel_2;
    TIM_ICInitStructure.TIM_ICPolarity = TIM_ICPolarity_Rising;
    TIM_ICInitStructure.TIM_ICSelection = TIM_ICSelection_IndirectTI;
    TIM_ICInitStructure.TIM_ICPrescaler = TIM_ICPSC_DIV1;
    TIM_ICInitStructure.TIM_ICFilter = 0x0;
    TIM_ICInit(TIM1, &TIM_ICInitStructure);

    // 使能更新中断
    TIM_ITConfig(TIM1, TIM_IT_Update, ENABLE);

    // 配置中断优先级
    NVIC_InitStructure.NVIC_IRQChannel = TIM1_UP_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);

    // 启动定时器
    TIM_Cmd(TIM1, ENABLE);
}

void GPIO_Configuration(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;

    // 使能GPIOA的时钟
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

    // 配置GPIO引脚
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8 | GPIO_Pin_9;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;
    GPIO_Init(GPIOA, &GPIO_InitStructure);
}

void TIM1_UP_IRQHandler(void)
{
    if (TIM_GetITStatus(TIM1, TIM_IT_Update) != RESET)
    {
        // 在这里处理编码器数据
        // 根据需要进行计数或其他操作

        TIM_ClearITPendingBit(TIM1, TIM_IT_Update);
    }
}

这个程序通过TIM1定时器接收编码器的数据，使用GPIOA的引脚8和9作为编码器的输入引脚。在`TIM1_UP_IRQHandler`中处理定时器的更新中断，可以在这里进行编码器数据的处理，例如进行计数操作。你可以根据实际需求修改程序中的参数和功能。请确保在编译和下载程序之前，已经正确配置了工程环境和引脚连接。
