/* *** NOTE ***********************************************************

        If you find your application is crashing here then likely causes are

        listed below.  In addition see http://www.freertos.org/FAQHelp.html for

        more tips, and ensure configASSERT() is defined!

        http://www.freertos.org/a00110.html#configASSERT

            1) Stack overflow -

               see http://www.freertos.org/Stacks-and-stack-overflow-checking.html

            2) Incorrect interrupt priority assignment, especially on Cortex-M

               parts where numerically high priority values denote low actual

               interrupt priorities, which can seem counter intuitive.  See

               http://www.freertos.org/RTOS-Cortex-M3-M4.html and the definition

               of configMAX_SYSCALL_INTERRUPT_PRIORITY on

               http://www.freertos.org/a00110.html

            3) Calling an API function from within a critical section or when

               the scheduler is suspended, or calling an API function that does

               not end in "FromISR" from an interrupt.

            4) Using a queue or semaphore before it has been initialised or

               before the scheduler has been started (are interrupts firing

               before vTaskStartScheduler() has been called?).
