STM32F103C8T6 PA0和PA1 进行ADC采样代码

您好，以下是针对您的问题的回答：

ADC采样代码如下：

#include "stm32f10x.h"

void ADC_Configuration(void)
{
ADC_InitTypeDef ADC_InitStructure;
GPIO_InitTypeDef GPIO_InitStructure;

RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1 | RCC_APB2Periph_GPIOA, ENABLE);

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_ | GPIO_Pin_1;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
GPIO_Init(GPIOA, &GPIO_InitStructure);

ADC_DeInit(ADC1);

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);

ADC_Cmd(ADC1, ENABLE);
}

u16 Get_Adc(u8 ch)
{
ADC_RegularChannelConfig(ADC1, ch, 1, ADC_SampleTime_239Cycles5);
ADC_SoftwareStartConvCmd(ADC1, ENABLE);
while(!ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC));
return ADC_GetConversionValue(ADC1);
}

int main(void)
{
u16 adc_value;

ADC_Configuration();

while(1)
{
adc_value = Get_Adc(ADC_Channel_);
}
}
