用stm32标准库配置ADC交叉通道配置代码

以下是使用STM32标准库配置ADC交叉通道的示例代码：

#include "stm32f4xx.h"

ADC_InitTypeDef ADC_InitStruct;
ADC_CommonInitTypeDef ADC_CommonInitStruct;

void ADC_Configuration(void)
{
  // Enable the clock for ADC1 and GPIOA
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);
  RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE);

  // Configure the GPIO pin as analog input
  GPIO_InitTypeDef GPIO_InitStruct;
  GPIO_InitStruct.GPIO_Pin = GPIO_Pin_0;
  GPIO_InitStruct.GPIO_Mode = GPIO_Mode_AN;
  GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_NOPULL;
  GPIO_Init(GPIOA, &GPIO_InitStruct);

  // Configure the ADC common parameters
  ADC_CommonInitStruct.ADC_Mode = ADC_Mode_Independent;
  ADC_CommonInitStruct.ADC_Prescaler = ADC_Prescaler_Div2;
  ADC_CommonInitStruct.ADC_DMAAccessMode = ADC_DMAAccessMode_Disabled;
  ADC_CommonInitStruct.ADC_TwoSamplingDelay = ADC_TwoSamplingDelay_5Cycles;
  ADC_CommonInit(&ADC_CommonInitStruct);

  // Configure ADC1
  ADC_InitStruct.ADC_Resolution = ADC_Resolution_12b;
  ADC_InitStruct.ADC_ScanConvMode = DISABLE;
  ADC_InitStruct.ADC_ContinuousConvMode = DISABLE;
  ADC_InitStruct.ADC_ExternalTrigConvEdge = ADC_ExternalTrigConvEdge_None;
  ADC_InitStruct.ADC_DataAlign = ADC_DataAlign_Right;
  ADC_InitStruct.ADC_NbrOfConversion = 2;
  ADC_Init(ADC1, &ADC_InitStruct);

  // Configure the ADC channels
  ADC_RegularChannelConfig(ADC1, ADC_Channel_0, 1, ADC_SampleTime_84Cycles);
  ADC_RegularChannelConfig(ADC1, ADC_Channel_1, 2, ADC_SampleTime_84Cycles);

  // Configure the ADC cross-channel mode
  ADC_CrossMultiModeConfig(ADC_Mode_Independent, ENABLE);
}

在上面的代码中，首先启用ADC1和GPIOA的时钟。然后，将GPIOA的PA0引脚配置为模拟输入。接下来，配置ADC的公共参数，例如采样分辨率和采样延迟等。然后，配置ADC1的通道，并将其分别与ADC_Channel_0和ADC_Channel_1相对应。最后，启用ADC的交叉通道模式。
