+  *    
+  *          This file overrides 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
