+
+  With Prescaler set to 479 and Period to 24999, the TIM7 counter is updated each 250 ms

+  SystemCoreClock variable holds HCLK frequency and is defined in system_stm32f0xx.c file.
+  Each time the core clock (HCLK) changes, user had to call SystemCoreClockUpdate()
+  function to update SystemCoreClock variable value. Otherwise, any configuration
+  based on this variable will be incorrect.
