声控模块接在stm32代码

下面是一个基本的声控模块接口代码示例，你可以根据实际情况进行修改和优化：

#include "stm32f1xx.h"
#include "stdio.h"

#define SOUND_IN_PIN    GPIO_Pin_0
#define SOUND_IN_PORT   GPIOA
#define SOUND_EXTI_LINE EXTI_Line0
#define SOUND_ADC_CH    ADC_Channel_0
#define SOUND_ADC_SMPR  ADC_SampleTime_239Cycles5

void GPIO_Configuration(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

    GPIO_InitStructure.GPIO_Pin = SOUND_IN_PIN;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPD;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(SOUND_IN_PORT, &GPIO_InitStructure);
}

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

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE);

    GPIO_EXTILineConfig(GPIO_PortSourceGPIOA, GPIO_PinSource0);

    EXTI_InitStructure.EXTI_Line = SOUND_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);

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

void ADC_Configuration(void)
{
    ADC_InitTypeDef ADC_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);

    ADC_DeInit(ADC1);

    ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;
    ADC_InitStructure.ADC_ScanConvMode = DISABLE;
    ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;
    ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;
    ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
    ADC_InitStructure.ADC_NbrOfChannel = 1;
    ADC_Init(ADC1, &ADC_InitStructure);

    ADC_RegularChannelConfig(ADC1, SOUND_ADC_CH, 1, SOUND_ADC_SMPR);

    ADC_Cmd(ADC1, ENABLE);

    ADC_ResetCalibration(ADC1);
    while(ADC_GetResetCalibrationStatus(ADC1));
    ADC_StartCalibration(ADC1);
    while(ADC_GetCalibrationStatus(ADC1));
}

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

    while(1)
    {
        // 等待中断响应
    }
}

void EXTI0_IRQHandler(void)
{
    if(EXTI_GetITStatus(SOUND_EXTI_LINE) != RESET)
    {
        uint16_t adc_value;

        // 读取ADC值
        ADC_SoftwareStartConvCmd(ADC1, ENABLE);
        while(ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC) == RESET);
        adc_value = ADC_GetConversionValue(ADC1);

        // 根据声音信号强度或频率等特征进行处理
        // ...

        EXTI_ClearITPendingBit(SOUND_EXTI_LINE);
    }
}

以上代码中，通过GPIO配置声控模块的输入引脚，并将其作为外部中断输入。然后，配置ADC模块将声音信号转换为数字信号，并在中断响应时读取ADC值进行处理。需要注意的是，这里的处理方式仅供参考，具体的处理方式需要根据实际情况进行设计和优化。
