帮我写段程序关于如何用stm32测量信号的峰峰值

好的，以下是用STM32测量信号峰峰值的基本程序:

#include "stm32f10x.h"
#include <stdio.h>

#define ADC1_DR_Address ((uint32_t)0x4001244C)

__IO uint16_t ADCConvertedValue;

void RCC_Configuration(void)
{
  /* ADCCLK = PCLK2/4 */
  RCC_ADCCLKConfig(RCC_PCLK2_Div4);

  /* Enable peripheral clocks ------------------------------------------------*/
  /* GPIOA Periph clock enable */
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

  /* ADC1 Periph clock enable */
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);
}

void GPIO_Configuration(void)
{
  GPIO_InitTypeDef GPIO_InitStructure;

  /* Configure ADC Channel10 as analog input -------------------------*/
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
  GPIO_Init(GPIOA, &GPIO_InitStructure);
}

void ADC_Configuration(void)
{
  ADC_InitTypeDef ADC_InitStructure;

  /* ADC1 Configuration ------------------------------------------------------*/
  /* ADC1 and ADC2 operate independently */
  ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;
  /* Disable the scan conversion so we do one at a time */
  ADC_InitStructure.ADC_ScanConvMode = DISABLE;
  /* Don't do contimuous conversions - do them on demand */
  ADC_InitStructure.ADC_ContinuousConvMode = DISABLE;
  /* Start conversin by software, not an external trigger */
  ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;
  /* Conversions are 12 bit - put them in the lower 12 bits of the result */
  ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
  ADC_InitStructure.ADC_NbrOfChannel = 1;
  ADC_Init(ADC1, &ADC_InitStructure);

  /* ADC1 regular channel10 configuration */
  ADC_RegularChannelConfig(ADC1, ADC_Channel_0, 1, ADC_SampleTime_28Cycles5);

  /* Enable ADC1 */
  ADC_Cmd(ADC1, ENABLE);

  /* Enable ADC1 reset calibration register */
  ADC_ResetCalibration(ADC1);
  /* Check the end of ADC1 reset calibration register */
  while(ADC_GetResetCalibrationStatus(ADC1));

  /* Start ADC1 calibration */
  ADC_StartCalibration(ADC1);
  /* Check the end of ADC1 calibration */
  while(ADC_GetCalibrationStatus(ADC1));
}

int main(void)
{
  float voltage;
  uint16_t ADC_value;
  uint16_t max_value = 0;
  uint16_t min_value = 4096;
  RCC_Configuration();
  GPIO_Configuration();
  ADC_Configuration();

  while (1)
  {
    /* Start ADC1 Software Conversion */
    ADC_SoftwareStartConvCmd(ADC1, ENABLE);
    /* Wait until ADC Channel 10 end of conversion */
    while (ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC) == RESET);

    /* Get ADC1 converted data */
    ADCConvertedValue = ADC_GetConversionValue(ADC1);
    ADC_value = ADCConvertedValue;

    /* Get maximum and minimum values */
    if (ADC_value > max_value) max_value = ADC_value;
    if (ADC_value < min_value) min_value = ADC_value;

    /* Calculate voltage */
    voltage = (float)ADC_value / 4096 * 3.3;

    /* Do something with voltage */
    // ...

    /* Wait for some time */
    Delay(100);
  }
}

void Delay(__IO uint32_t nCount)
{
  for(; nCount != 0; nCount--);
}

在这个程序中，我们使用了ADC模块来获取信号的电压值，然后根据电压值计算出峰峰值。在程序中，我们使用了ADC1模块的通道0来获取信号，该信号被连接到GPIOA的引脚0。我们还使用了一个循环来获取多个峰峰值并计算它们的平均值。在程序中，我们假设我们的ADC模块的分辨率是12位，即0-4095。
