库函数写读取8个通道的采样结果保存到RAM;以stm32f403zgt6芯片

下面是一个使用标准库函数将8个通道的采样结果保存到RAM的代码示例，适用于STM32F403ZGT6芯片：

#include "stm32f4xx.h"

#define ADC_CHANNELS 8
#define ADC_BUFFER_SIZE (ADC_CHANNELS * 10) // 10个采样点

uint16_t adcBuffer[ADC_BUFFER_SIZE];

void ADC_Config(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    ADC_InitTypeDef ADC_InitStructure;
    ADC_CommonInitTypeDef ADC_CommonInitStructure;
    DMA_InitTypeDef DMA_InitStructure;

    // 使能外设时钟
    RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE);
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);
    RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA2, ENABLE);

    // 配置ADC引脚
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0 | GPIO_Pin_1 | GPIO_Pin_2 | GPIO_Pin_3 |
                                  GPIO_Pin_4 | GPIO_Pin_5 | GPIO_Pin_6 | GPIO_Pin_7;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AN;
    GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // 配置DMA
    DMA_InitStructure.DMA_Channel = DMA_Channel_0;
    DMA_InitStructure.DMA_PeripheralBaseAddr = (uint32_t)&ADC1->DR;
    DMA_InitStructure.DMA_Memory0BaseAddr = (uint32_t)&adcBuffer;
    DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralToMemory;
    DMA_InitStructure.DMA_BufferSize = ADC_BUFFER_SIZE;
    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_FIFOMode = DMA_FIFOMode_Disable;
    DMA_InitStructure.DMA_FIFOThreshold = DMA_FIFOThreshold_HalfFull;
    DMA_InitStructure.DMA_MemoryBurst = DMA_MemoryBurst_Single;
    DMA_InitStructure.DMA_PeripheralBurst = DMA_PeripheralBurst_Single;
    DMA_Init(DMA2_Stream0, &DMA_InitStructure);

    // 配置ADC
    ADC_CommonInitStructure.ADC_Mode = ADC_Mode_Independent;
    ADC_CommonInitStructure.ADC_Prescaler = ADC_Prescaler_Div2;
    ADC_CommonInitStructure.ADC_DMAAccessMode = ADC_DMAAccessMode_Disabled;
    ADC_CommonInitStructure.ADC_TwoSamplingDelay = ADC_TwoSamplingDelay_5Cycles;
    ADC_CommonInit(&ADC_CommonInitStructure);

    ADC_InitStructure.ADC_Resolution = ADC_Resolution_12b;
    ADC_InitStructure.ADC_ScanConvMode = ENABLE;
    ADC_InitStructure.ADC_ContinuousConvMode = DISABLE;
    ADC_InitStructure.ADC_ExternalTrigConvEdge = ADC_ExternalTrigConvEdge_None;
    ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
    ADC_InitStructure.ADC_NbrOfConversion = ADC_CHANNELS;
    ADC_Init(ADC1, &ADC_InitStructure);

    // 配置ADC通道顺序
    ADC_RegularChannelConfig(ADC1, ADC_Channel_0, 1, ADC_SampleTime_3Cycles);
    ADC_RegularChannelConfig(ADC1, ADC_Channel_1, 2, ADC_SampleTime_3Cycles);
    ADC_RegularChannelConfig(ADC1, ADC_Channel_2, 3, ADC_SampleTime_3Cycles);
    ADC_RegularChannelConfig(ADC1, ADC_Channel_3, 4, ADC_SampleTime_3Cycles);
    ADC_RegularChannelConfig(ADC1, ADC_Channel_4, 5, ADC_SampleTime_3Cycles);
    ADC_RegularChannelConfig(ADC1, ADC_Channel_5, 6, ADC_SampleTime_3Cycles);
    ADC_RegularChannelConfig(ADC1, ADC_Channel_6, 7, ADC_SampleTime_3Cycles);
    ADC_RegularChannelConfig(ADC1, ADC_Channel_7, 8, ADC_SampleTime_3Cycles);

    // 使能DMA请求
    ADC_DMACmd(ADC1, ENABLE);

    // 启动DMA
    DMA_Cmd(DMA2_Stream0, ENABLE);

    // 启动ADC转换
    ADC_Cmd(ADC1, ENABLE);

    // 等待ADC稳定
    delay_us(10);

    // 启动连续转换
    ADC_SoftwareStartConv(ADC1);
}

int main(void)
{
    ADC_Config();

    while (1)
    {
        // 进行其他任务
        
        // 读取采样结果
        for (int i = 0; i < ADC_BUFFER_SIZE; i++)
        {
            uint16_t adcValue = adcBuffer[i];
            // 将采样结果保存到RAM或进行其他处理
            // ...
        }
    }
}

以上代码使用了STM32标准库函数来配置ADC和DMA，实现了连续采样8个通道的结果，并将结果保存到`adcBuffer`数组中。你可以在主循环中读取`adcBuffer`数组的值，并将采样结果保存到RAM或进行其他处理。

请注意，以上代码仅供参考，具体的配置可能因芯片型号和使用的开发环境而有所不同。请根据实际情况进行适当的修改。
