基stm32f103的AD显示在OLCD代码

以下代码是基于STM32F103的ADC和OLED显示屏的基础上，实现将ADC采集到的数据显示在OLED屏幕上的示例代码：

#include "stm32f10x.h"
#include "oled.h"
#include "delay.h"

ADC_InitTypeDef ADC_InitStructure;
GPIO_InitTypeDef GPIO_InitStructure;

void ADC_Configuration(void)
{
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_ADC1, ENABLE);

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

  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_RegularChannelConfig(ADC1, ADC_Channel_1, 1, ADC_SampleTime_1Cycles5);
  ADC_Cmd(ADC1, ENABLE);
  ADC_ResetCalibration(ADC1);
  while(ADC_GetResetCalibrationStatus(ADC1));
  ADC_StartCalibration(ADC1);
  while(ADC_GetCalibrationStatus(ADC1));
}

int main(void)
{
  u16 ad_value;
  char str[16];

  OLED_Init();
  ADC_Configuration();
  
  while(1)
  {
    ADC_SoftwareStartConvCmd(ADC1, ENABLE);
    while(!ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC));
    ad_value = ADC_GetConversionValue(ADC1);
    sprintf(str, "ADC:%d", ad_value);
    OLED_ShowString(0, 0, str, 1);
    delay_ms(1000);
  }
}

代码中首先进行了ADC的配置，设置了GPIOA1为模拟输入，ADC1的采样模式为单次采样。在主函数中，循环读取ADC采样到的数据，将其转换成字符串格式，并显示在OLED屏幕上。为了避免显示过快，添加了1秒的延时。
