stm32收集火焰传感器的信息代码

以下是使用STM32收集火焰传感器信息的示例代码，仅供参考：

/* Includes ------------------------------------------------------------------*/
#include "stm32f10x.h"
#include "delay.h"
#include "usart.h"
#include "adc.h"

/* Private typedef -----------------------------------------------------------*/
/* Private define ------------------------------------------------------------*/
#define FLAME_SENSOR_PORT GPIOA
#define FLAME_SENSOR_PIN GPIO_Pin_0

/* Private macro -------------------------------------------------------------*/
/* Private variables ---------------------------------------------------------*/
/* Private function prototypes -----------------------------------------------*/
/* Private functions ---------------------------------------------------------*/

/**
  * @brief  Main program
  * @param  None
  * @retval None
  */
int main(void)
{
  uint16_t flame_value;

  /* Initialize delay */
  DelayInit();

  /* Initialize USART */
  USART1_Init();

  /* Initialize ADC */
  ADC1_Init();

  /* Configure flame sensor pin as input */
  GPIO_InitTypeDef GPIO_InitStructure;
  GPIO_InitStructure.GPIO_Pin = FLAME_SENSOR_PIN;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
  GPIO_Init(FLAME_SENSOR_PORT, &GPIO_InitStructure);

  while (1)
  {
    /* Read flame sensor value */
    flame_value = ADC1_ReadChannel(ADC_Channel_0);

    /* Print flame sensor value to USART */
    USART1_Printf("Flame sensor value: %d\r\n", flame_value);

    /* Delay for some time */
    DelayMs(1000);
  }
}

在上面的示例代码中，我们使用了STM32的ADC模块来读取火焰传感器的模拟信号，并通过USART串口将读取到的数值发送出去。在使用该代码前，需要先初始化GPIO、USART和ADC模块，以及配置火焰传感器的引脚为输入模式。
