帮我用stm32f103写一下这个项目中使用红外得到旋转的位置和速度，并添加取模信息的代码吧

当使用STM32F103编写十字旋转LED POV项目时，你可以利用外部中断和定时器来实现红外对管的使用，并获取旋转的位置和速度。下面是一个基本的代码框架，你可以根据具体需求进行修改和完善：

#include "stm32f10x.h"

#define IR_PIN GPIO_Pin_0
#define IR_PORT GPIOA

volatile uint32_t pulseCount = 0;
volatile uint32_t prevPulseCount = 0;
volatile uint32_t rotationSpeed = 0;
volatile uint32_t rotationPosition = 0;

void EXTI0_IRQHandler(void)
{
    if (EXTI_GetITStatus(EXTI_Line0) != RESET)
    {
        pulseCount++;
        EXTI_ClearITPendingBit(EXTI_Line0);
    }
}

void TIM2_IRQHandler(void)
{
    if (TIM_GetITStatus(TIM2, TIM_IT_Update) != RESET)
    {
        rotationSpeed = pulseCount - prevPulseCount;
        prevPulseCount = pulseCount;
        rotationPosition += rotationSpeed;

        TIM_ClearITPendingBit(TIM2, TIM_IT_Update);
    }
}

void GPIO_Configuration(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

    GPIO_InitStructure.GPIO_Pin = IR_PIN;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(IR_PORT, &GPIO_InitStructure);
}

void EXTI_Configuration(void)
{
    EXTI_InitTypeDef EXTI_InitStructure;
    NVIC_InitTypeDef NVIC_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE);
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

    GPIO_EXTILineConfig(GPIO_PortSourceGPIOA, GPIO_PinSource0);

    EXTI_InitStructure.EXTI_Line = EXTI_Line0;
    EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt;
    EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Rising_Falling;
    EXTI_InitStructure.EXTI_LineCmd = ENABLE;
    EXTI_Init(&EXTI_InitStructure);

    NVIC_InitStructure.NVIC_IRQChannel = EXTI0_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0x00;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0x00;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);
}

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

    RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE);

    TIM_TimeBaseStructure.TIM_Period = 9999; // 根据实际需求进行设置
    TIM_TimeBaseStructure.TIM_Prescaler = 7199; // 根据实际需求进行设置
    TIM_TimeBaseStructure.TIM_ClockDivision = 0;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);

    TIM_ClearFlag(TIM2, TIM_FLAG_Update);
    TIM_ITConfig(TIM2, TIM_IT_Update, ENABLE);
    TIM_Cmd(TIM2, ENABLE);

    NVIC_InitStructure.NVIC_IRQChannel = TIM2_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0x01;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0x00;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);
}

int main(void)
{
    GPIO_Configuration();
    EXTI_Configuration();
    TIM_Configuration();

    while (1)
    {
        // 在这里添加你的取模信息处理逻辑
    }
}

上述代码中，我们使用了外部中断和定时器来实现红外对管的使用。在外部中断中，我们计算脉冲的数量；而在定时器中断中，我们计算旋转的速度和位置。你可以根据具体需求进行修改，例如设置定时器的预分频和周期，以及根据旋转的速度和位置控制LED灯的亮灭。

请注意，以上代码仅为参考示例，具体实现需要根据硬件和功能需求进行适当的调整和修改。
