+  * @file    stm32f0xx_hal_timebase_tim_template.c 
+  * @brief   HAL time base based on the hardware TIM Template.
+  *    
+  *          This file override the native HAL time base functions (defined as weak)
+  *          the TIM time base:
+  *           + Intializes the TIM peripheral generate a Period elapsed Event each 1ms
+  *           + HAL_IncTick is called inside HAL_TIM_PeriodElapsedCallback ie each 1ms
