基于stm32f103c8t6,用HAL库函数编写一个声音控制LED灯的代码

您好，我可以回答这个问题。以下是基于stm32f103c8t6，用HAL库函数编写一个声音控制LED灯的代码：

#include "stm32f1xx_hal.h"

#define ADC_CHANNEL 0 //声音传感器连接的ADC通道
#define LED_PIN GPIO_PIN_13 //LED灯连接的GPIO引脚
#define LED_PORT GPIOC //LED灯连接的GPIO端口

ADC_HandleTypeDef hadc1;

void SystemClock_Config(void);
static void MX_GPIO_Init(void);
static void MX_ADC1_Init(void);

int main(void)
{
HAL_Init();
SystemClock_Config();
MX_GPIO_Init();
MX_ADC1_Init();

uint32_t adc_value = 0; //存储ADC采集到的声音传感器的值

while (1)
{
HAL_ADC_Start(&hadc1); //启动ADC采集
HAL_ADC_PollForConversion(&hadc1, 100); //等待ADC采集完成
adc_value = HAL_ADC_GetValue(&hadc1); //获取ADC采集到的值
HAL_ADC_Stop(&hadc1); //停止ADC采集

if (adc_value > 500) //当声音传感器的值大于500时，LED灯亮起
{
HAL_GPIO_WritePin(LED_PORT, LED_PIN, GPIO_PIN_SET);
}
else //否则，LED灯熄灭
{
HAL_GPIO_WritePin(LED_PORT, LED_PIN, GPIO_PIN_RESET);
}
}
}

void SystemClock_Config(void)
{

}

{

}
}

hadc1.Init.NbrOfConversion = 1;
if (HAL_ADC_Init(&hadc1) != HAL_OK)
{
Error_Handler();
}

sConfig.Channel = ADC_CHANNEL;
sConfig.Rank = ADC_REGULAR_RANK_1;
sConfig.SamplingTime = ADC_SAMPLETIME_13CYCLES_5;
if (HAL_ADC_ConfigChannel(&hadc1, &sConfig) != HAL_OK)
{
Error_Handler();
}
}

static void MX_GPIO_Init(void)
{

__HAL_RCC_GPIOC_CLK_ENABLE();

GPIO_InitStruct.Pin = LED_PIN;

希望能对您有所帮助。
