给我一份stm32f1使用标准库，adc1 通道0采集的数据使用dma传输到串口1 PA9发送，控制频率为16khz

好的，以下是使用标准库实现的代码：

#include "stm32f10x.h"

#define ADC1_DR_Address    ((uint32_t)0x4001244C) // ADC1数据寄存器地址
#define ADC_BUF_SIZE       1024 // ADC数据缓存大小

uint16_t ADC1_Value[ADC_BUF_SIZE]; // ADC1数据缓存
uint16_t ADC_Index = 0; // ADC1数据缓存索引

void RCC_Configuration(void);
void GPIO_Configuration(void);
void ADC_Configuration(void);
void DMA_Configuration(void);
void USART_Configuration(void);
void NVIC_Configuration(void);

int main(void)
{
    RCC_Configuration();
    GPIO_Configuration();
    ADC_Configuration();
    DMA_Configuration();
    USART_Configuration();
    NVIC_Configuration();

    ADC_SoftwareStartConvCmd(ADC1, ENABLE); // 开始ADC转换

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

        // 发送数据
        USART_SendData(USART1, (uint16_t)ADC1_Value[ADC_Index++]);

        // 重置索引
        if (ADC_Index >= ADC_BUF_SIZE)
        {
            ADC_Index = 0;
        }

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

void RCC_Configuration(void)
{
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_ADC1 | RCC_APB2Periph_USART1, ENABLE);
    RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE);
}

{

    // ADC1通道0 PA0配置
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;

    GPIO_Init(GPIOA, &GPIO_InitStructure);

    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);
}

void ADC_Configuration(void)
{
    ADC_InitTypeDef ADC_InitStructure;

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

    // ADC1规则组配置
    ADC_RegularChannelConfig(ADC1, ADC_Channel_0, 1, ADC_SampleTime_28Cycles5);

    // DMA配置
    ADC_DMACmd(ADC1, ENABLE); // 使能ADC1 DMA传输
}

void DMA_Configuration(void)
{
    DMA_InitTypeDef DMA_InitStructure;

    // DMA1通道1配置
    DMA_InitStructure.DMA_PeripheralBaseAddr = ADC1_DR_Address; // 源地址：ADC1数据寄存器地址
    DMA_InitStructure.DMA_MemoryBaseAddr = (uint32_t)ADC1_Value; // 目标地址：ADC1数据缓存
    DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralSRC;
    DMA_InitStructure.DMA_BufferSize = ADC_BUF_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_M2M = DMA_M2M_Disable;
    DMA_Init(DMA1_Channel1, &DMA_InitStructure);

    DMA_Cmd(DMA1_Channel1, ENABLE); // 使能DMA1通道1
}

void USART_Configuration(void)
{
    USART_InitTypeDef USART_InitStructure;

    // USART1配置
    USART_InitStructure.USART_BaudRate = 115200;
    USART_InitStructure.USART_WordLength = USART_WordLength_9b;
    USART_InitStructure.USART_StopBits = USART_StopBits_1;
    USART_InitStructure.USART_Parity = USART_Parity_Even;
    USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
    USART_InitStructure.USART_Mode = USART_Mode_Tx;
    USART_Init(USART1, &USART_InitStructure);

    USART_Cmd(USART1, ENABLE); // 使能USART1
}

void NVIC_Configuration(void)
{
    NVIC_InitTypeDef NVIC_InitStructure;

    // DMA1通道1中断配置
    NVIC_InitStructure.NVIC_IRQChannel = DMA1_Channel1_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);

    DMA_ITConfig(DMA1_Channel1, DMA_IT_TC, ENABLE); // 使能DMA1通道1传输完成中断
}

void DMA1_Channel1_IRQHandler(void)
{
    DMA_ClearITPendingBit(DMA1_IT_TC1); // 清除DMA1通道1传输完成中断标志
}

需要注意的是，上述代码中的 ADC_BUF_SIZE 定义了 ADC 数据缓存的大小，可以根据需要进行修改。同时，USART 配置的波特率为 115200，可以根据需要进行修改。
