使用stm32cumemx配置stm32f103ze的PF8脚做ADC采集，使用DMA方式，详细配置步骤及代码

以下是配置步骤及代码：

1. 配置ADC外设和GPIO外设

/* 使能 ADC1 时钟 */
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);

/* 使能 GPIOF 时钟 */
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOF, ENABLE);

GPIO_InitTypeDef GPIO_InitStructure;

/* 配置 PF8 为模拟输入 */
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
GPIO_Init(GPIOF, &GPIO_InitStructure);

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

/* 配置 ADC1 通道 6 */
ADC_RegularChannelConfig(ADC1, ADC_Channel_6, 1, ADC_SampleTime_55Cycles5);

2. 配置DMA外设

/* 使能 DMA1 时钟 */
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE);

DMA_InitTypeDef DMA_InitStructure;
DMA_InitStructure.DMA_PeripheralBaseAddr = (uint32_t) &(ADC1->DR);
DMA_InitStructure.DMA_MemoryBaseAddr = (uint32_t) ADC_Value;
DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralSRC;
DMA_InitStructure.DMA_BufferSize = 1;
DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable;
DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Enable;
DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_HalfWord;
DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord;
DMA_InitStructure.DMA_Mode = DMA_Mode_Circular;
DMA_InitStructure.DMA_Priority = DMA_Priority_High;
DMA_InitStructure.DMA_M2M = DMA_M2M_Disable;
DMA_Init(DMA1_Channel1, &DMA_InitStructure);

/* 使能 DMA 通道 */
DMA_Cmd(DMA1_Channel1, ENABLE);

3. 启动ADC采集和DMA传输

/* 启动 ADC1 */
ADC_Cmd(ADC1, ENABLE);

/* 启动 DMA 传输 */
DMA_Cmd(DMA1_Channel1, ENABLE);

/* 启动 ADC1 转换 */
ADC_SoftwareStartConvCmd(ADC1, ENABLE);

4. 在中断处理函数中处理数据

void DMA1_Channel1_IRQHandler(void)
{
    if (DMA_GetITStatus(DMA1_IT_TC1))
    {
        /* 清除 DMA1 通道 1 的传输完成中断标志位 */
        DMA_ClearITPendingBit(DMA1_IT_TC1);

        /* 处理数据 */
        uint16_t adc_value = ADC_Value[0];
    }
}

完整代码如下：

#include "stm32f10x.h"

uint16_t ADC_Value[1];

int main(void)
{
    /* 使能 ADC1 时钟 */
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);

    /* 使能 GPIOF 时钟 */
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOF, ENABLE);

    GPIO_InitTypeDef GPIO_InitStructure;

    /* 配置 PF8 为模拟输入 */
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
    GPIO_Init(GPIOF, &GPIO_InitStructure);

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

    /* 配置 ADC1 通道 6 */
    ADC_RegularChannelConfig(ADC1, ADC_Channel_6, 1, ADC_SampleTime_55Cycles5);

    /* 使能 DMA1 时钟 */
    RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE);

    DMA_InitTypeDef DMA_InitStructure;
    DMA_InitStructure.DMA_PeripheralBaseAddr = (uint32_t) &(ADC1->DR);
    DMA_InitStructure.DMA_MemoryBaseAddr = (uint32_t) ADC_Value;
    DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralSRC;
    DMA_InitStructure.DMA_BufferSize = 1;
    DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable;
    DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Enable;
    DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_HalfWord;
    DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord;
    DMA_InitStructure.DMA_Mode = DMA_Mode_Circular;
    DMA_InitStructure.DMA_Priority = DMA_Priority_High;
    DMA_InitStructure.DMA_M2M = DMA_M2M_Disable;
    DMA_Init(DMA1_Channel1, &DMA_InitStructure);

    /* 使能 DMA 传输完成中断 */
    DMA_ITConfig(DMA1_Channel1, DMA_IT_TC, ENABLE);

    /* 使能 DMA 通道 */
    DMA_Cmd(DMA1_Channel1, ENABLE);

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

    /* 启动 ADC1 转换 */
    ADC_SoftwareStartConvCmd(ADC1, ENABLE);

    while (1)
    {
    }
}

void DMA1_Channel1_IRQHandler(void)
{
    if (DMA_GetITStatus(DMA1_IT_TC1))
    {
        /* 清除 DMA1 通道 1 的传输完成中断标志位 */
        DMA_ClearITPendingBit(DMA1_IT_TC1);

        /* 处理数据 */
        uint16_t adc_value = ADC_Value[0];
    }
}
