================================================================================
           
  [..]       
      The STM32F0xx device family integrates up to 2 analog comparators COMP1 and COMP2:
      (#) The non inverting input and inverting input can be set to GPIO pins
          as shown in table1. COMP Inputs below.
  
      (#) The COMP output is available using HAL_COMP_GetOutputLevel()
          and can be set on GPIO pins. Refer to table 2. COMP Outputs below.
  
      (#) The COMP output can be redirected to embedded timers (TIM1, TIM2 and TIM3)
          Refer to table 3. COMP Outputs redirection to embedded timers below.
  
      (#) The comparators COMP1 and COMP2 can be combined in window mode.
  
      (#) The comparators have interrupt capability with wake-up
          from Sleep and Stop modes (through the EXTI controller):
          (++) COMP1 is internally connected to EXTI Line 21
          (++) COMP2 is internally connected to EXTI Line 22
          From the corresponding IRQ handler, the right interrupt source can be retrieved with the 
          macro __HAL_COMP_EXTI_GET_FLAG(). Possible values are:
          (++) COMP_EXTI_LINE_COMP1_EVENT
          (++) COMP_EXTI_LINE_COMP2_EVENT

            ##### How to use this driver #####
================================================================================
  [..]
      This driver provides functions to configure and program the Comparators of STM32F05x and STM32F07x devices.

      To use the comparator, perform the following steps:
  
      (#) Fill in the HAL_COMP_MspInit() to
      (++) Configure the comparator input in analog mode using HAL_GPIO_Init()
      (++) Configure the comparator output in alternate function mode using HAL_GPIO_Init() to map the comparator 
           output to the GPIO pin
      (++) If required enable the COMP interrupt by configuring and enabling EXTI line in Interrupt mode and 
           selecting the desired sensitivity level using HAL_GPIO_Init() function. After that enable the comparator
           interrupt vector using HAL_NVIC_EnableIRQ() function.
  
      (#) Configure the comparator using HAL_COMP_Init() function:
      (++) Select the inverting input
      (++) Select the non inverting input
      (++) Select the output polarity  
      (++) Select the output redirection
      (++) Select the hysteresis level
      (++) Select the power mode
      (++) Select the event/interrupt mode
  
      (#) Enable the comparator using HAL_COMP_Start() function or HAL_COMP_Start_IT() function for interrupt mode
    
      (#) Read the comparator output level with HAL_COMP_GetOutputLevel()
