使用标准库，stm32F103c8t6芯片 使用定时器触发adc采样，10ms采样一次

可以使用定时器中断来触发ADC采样，具体实现可以参考以下代码：

#include "stm32f10x.h"

void ADC1_Init(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    ADC_InitTypeDef ADC_InitStructure;
    DMA_InitTypeDef DMA_InitStructure;

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

    // 配置ADC1通道16所用到的GPIO
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC, ENABLE);
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
    GPIO_Init(GPIOC, &GPIO_InitStructure);

    // 配置ADC1的DMA
    RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE);
    DMA_DeInit(DMA1_Channel1);
    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_Disable;
    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);

    // 配置ADC1
    ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;
    ADC_InitStructure.ADC_ScanConvMode = DISABLE;
    ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;
    ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_T3_TRGO;
    ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
    ADC_InitStructure.ADC_NbrOfChannel = 1;
    ADC_Init(ADC1, &ADC_InitStructure);

    // 配置ADC1的通道16
    ADC_RegularChannelConfig(ADC1, ADC_Channel_10, 1, ADC_SampleTime_239Cycles5);

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

    // 使能ADC1
    ADC_Cmd(ADC1, ENABLE);

    // 开始ADC1的转换
    ADC_SoftwareStartConvCmd(ADC1, ENABLE);
}

void TIM3_Init(void)
{
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    NVIC_InitTypeDef NVIC_InitStructure;

    // 使能TIM3时钟
    RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3, ENABLE);

    // 配置TIM3的时基
    TIM_TimeBaseStructure.TIM_Period = 999;
    TIM_TimeBaseStructure.TIM_Prescaler = 7199;
    TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM3, &TIM_TimeBaseStructure);

    // 配置TIM3的中断
    NVIC_InitStructure.NVIC_IRQChannel = TIM3_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);

    // 使能TIM3的更新中断
    TIM_ITConfig(TIM3, TIM_IT_Update, ENABLE);

    // 启动TIM3
    TIM_Cmd(TIM3, ENABLE);
}

void TIM3_IRQHandler(void)
{
    if (TIM_GetITStatus(TIM3, TIM_IT_Update) != RESET)
    {
        // 清除TIM3的更新中断标志位
        TIM_ClearITPendingBit(TIM3, TIM_IT_Update);

        // 开始ADC1的转换
        ADC_SoftwareStartConvCmd(ADC1, ENABLE);
    }
}

int main(void)
{
    ADC1_Init();
    TIM3_Init();

    while (1)
    {
        // 等待ADC1的DMA传输完成
        while (DMA_GetFlagStatus(DMA1_FLAG_TC1) == RESET);

        // 处理ADC1的采样值
        // ...

        // 清除ADC1的DMA传输完成标志位
        DMA_ClearFlag(DMA1_FLAG_TC1);
    }
}

其中，TIM3用来触发ADC1的转换，每10ms触发一次；ADC1的采样值通过DMA传输到内存中，可以在main函数中处理。
