  * @brief   HAL time base based on the hardware TIM.
  *
  *          This file overrides the native HAL time base functions (defined as weak)
  *          the TIM time base:
  *           + Initializes the TIM peripheral to generate a Period elapsed Event each 1ms
  *           + HAL_IncTick is called inside HAL_TIM_PeriodElapsedCallback ie each 1ms

  ==============================================================================
    [..]
    This file must be copied to the application folder and modified as follows:
    (#) Rename it to 'stm32wbxx_hal_timebase_tim.c'
    (#) Add this file and the TIM HAL driver files to your project and make sure
       HAL_TIM_MODULE_ENABLED is defined in stm32wbxx_hal_conf.h

    [..]
    (@) The application needs to ensure that the time base is always set to 1 millisecond
       to have correct HAL operation.
