stm32写一个雨滴传感器模块代码

你好，我是 CSDN 开发的 C 知道。关于您的问题，我可以回答。以下是一个基于 STM32 的雨滴传感器模块的代码示例：

#include "stm32f10x.h"

#define RAIN_SENSOR_PIN GPIO_Pin_
#define RAIN_SENSOR_PORT GPIOA

void GPIO_Configuration(void);
void EXTI_Configuration(void);
void NVIC_Configuration(void);

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

    while (1)
    {
        // 在这里编写您的主程序
    }
}

void GPIO_Configuration(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

    GPIO_InitStructure.GPIO_Pin = RAIN_SENSOR_PIN;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPD;
    GPIO_Init(RAIN_SENSOR_PORT, &GPIO_InitStructure);
}

void EXTI_Configuration(void)
{
    EXTI_InitTypeDef EXTI_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE);

    GPIO_EXTILineConfig(GPIO_PortSourceGPIOA, GPIO_PinSource);

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

void NVIC_Configuration(void)
{
    NVIC_InitTypeDef NVIC_InitStructure;

    NVIC_PriorityGroupConfig(NVIC_PriorityGroup_);

    NVIC_InitStructure.NVIC_IRQChannel = EXTI_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = ;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = ;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);
}

void EXTI_IRQHandler(void)
{
    if (EXTI_GetITStatus(EXTI_Line) != RESET)
    {
        // 在这里编写您的中断处理程序

        EXTI_ClearITPendingBit(EXTI_Line);
    }
}

以上是一个基本的代码示例，您可以根据您的具体需求进行修改和完善。希望对您有所帮助。
