stm32l4 ADC单通道采集temperature

STM32L4超低功耗单片机内部ADC操作代码，实现温度转换

/**
  ******************************************************************************
  * @file    Examples_LL/ADC/ADC_TemperatureSensor/Src/main.c
  * @author  MCD Application Team
  * @brief   This example describes how to use a ADC peripheral to perform
  *          a single ADC conversion of the internal temperature sensor
  *          and to calculate the temperature in degree Celsius; 
  *          Example using programming model: polling 
  *          （for programming models interrupt or DMA transfer refer to
  *          other examples）.
  *          This example is based on the STM32L4xx ADC LL API;
  *          Peripheral initialization done using LL unitary services functions.
