写一个由库函数的stm32f103c8t6通过adc采样转电压的代码

以下是使用库函数的stm32f103c8t6通过ADC采样转电压的代码：

#include "stm32f10x.h"

int main(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    ADC_InitTypeDef ADC_InitStructure;

    // Enable peripheral clocks
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_ADC1, ENABLE);

    // Configure ADC pin as analog input
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // Configure ADC
    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);

    // Configure ADC channel
    ADC_RegularChannelConfig(ADC1, ADC_Channel_0, 1, ADC_SampleTime_55Cycles5);

    // Enable ADC
    ADC_Cmd(ADC1, ENABLE);

    // Wait for ADC to warm up
    for (int i = 0; i < 1000; i++);

    // Start ADC conversion
    ADC_SoftwareStartConvCmd(ADC1, ENABLE);

    // Wait for ADC conversion to complete
    while (ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC) == RESET);

    // Read ADC converted value and convert to voltage
    uint16_t adc_value = ADC_GetConversionValue(ADC1);
    float voltage = (float)adc_value / 4096.0 * 3.3;

    // Infinite loop
    while (1);
}

这段代码使用的是ADC1的通道0进行采样，并将采样时间设置为55.5个时钟周期。采样完成后，将转换值转换为电压，并将其输出到控制台。
