使用stm32f103zet6 PB3为adc引脚进行读取ad程序

以下是使用stm32f103zet6 PB3引脚进行ADC读取的程序：

#include "stm32f10x.h"

void init_ADC(void);
void init_GPIO(void);
u16 read_ADC(void);

int main(void)
{
    u16 ADC_value;

    init_GPIO();
    init_ADC();

    while(1)
    {
        ADC_value = read_ADC();
        // do something with ADC_value
    }
}

void init_ADC(void)
{
    ADC_InitTypeDef ADC_InitStruct;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);

    ADC_DeInit(ADC1);

    ADC_InitStruct.ADC_Mode = ADC_Mode_Independent;
    ADC_InitStruct.ADC_ScanConvMode = DISABLE;
    ADC_InitStruct.ADC_ContinuousConvMode = ENABLE;
    ADC_InitStruct.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;
    ADC_InitStruct.ADC_DataAlign = ADC_DataAlign_Right;
    ADC_InitStruct.ADC_NbrOfChannel = 1;

    ADC_Init(ADC1, &ADC_InitStruct);

    ADC_Cmd(ADC1, ENABLE);

    ADC_ResetCalibration(ADC1);

    while(ADC_GetResetCalibrationStatus(ADC1));

    ADC_StartCalibration(ADC1);

    while(ADC_GetCalibrationStatus(ADC1));
}

void init_GPIO(void)
{
    GPIO_InitTypeDef GPIO_InitStruct;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE);

    GPIO_InitStruct.GPIO_Mode = GPIO_Mode_AIN;
    GPIO_InitStruct.GPIO_Pin = GPIO_Pin_3;

    GPIO_Init(GPIOB, &GPIO_InitStruct);
}

u16 read_ADC(void)
{
    ADC_RegularChannelConfig(ADC1, ADC_Channel_8, 1, ADC_SampleTime_55Cycles5);

    ADC_SoftwareStartConvCmd(ADC1, ENABLE);

    while(!ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC));

    return ADC_GetConversionValue(ADC1);
}
