+  * @author  MCD Application Team
+  * @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:
+  *           + Intializes 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 'stm32g0xx_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 stm32l4xx_hal_conf.h
+
+    [..]
+    (@) The application needs to ensure that the time base is always set to 1 millisecond
+       to have correct HAL operation.
