*
* With TRACE_RECORDER_STORE_MODE set to TRACE_STORE_MODE_RING_BUFFER, the events are
* stored in a ring buffer, i.e., where the oldest events are overwritten when
* the buffer becomes full. This allows you to get the last events leading up
* to an interesting state, e.g., an error, without having a large trace buffer
* for string the whole run since startup. In this mode, the recorder can run
* "forever" as the buffer never gets full, i.e., in the sense that it always
* has room for more events.
*
* To fetch the trace in mode TRACE_STORE_MODE_RING_BUFFER, you need to first halt the

* recorder using vTraceStop() and then store/upload the trace data using a
* task that you need to provide yourself. The trace data is found in the struct

*
* ### Instance Finish Events (IFE) ###
*
* For tasks with "infinite" main loops (non-terminating tasks), the concept
* of a task instance has no clear definition, it is an application-specific
* thing. Tracealyzer allows you to define Instance Finish Events (IFEs),
* which marks the point in a cyclic task when the "task instance" ends.
* The IFE is a blocking kernel call, typically in the main loop of a task
* which typically reads a message queue, waits for a semaphore or performs
* an explicit delay.
*
* If USE_IMPLICIT_IFE_RULES is one (1), the kernel macros (trcKernelPort.h)
* will define what kernel calls are considered by default to be IFEs.
*
* However, Implicit IFEs only applies to blocking kernel calls. If a
* service reads a message without blocking, it does not create a new
* instance since no blocking occurred.
*
* Moreover, the actual IFE might sometimes be another blocking call. We
* therefore allow for user-defined Explicit IFEs by calling
*
* vTraceTaskInstanceIsFinished()
*
* right before the kernel call considered as IFE. This does not create an
* additional event but instead stores the service code and object handle
* of the IFE call as properties of the task.
*
* If using Explicit IFEs and the task also calls an Implicit IFE, this may
* result in additional incorrect task instances.
* This is solved by disabling the Implicit IFEs for the task, by adding
* a call to
*
* vTraceTaskSkipDefaultInstanceFinishedEvents()
*
* in the very beginning of that task. This allows you to combine Explicit IFEs
* for some tasks with Implicit IFEs for the rest of the tasks, if
* USE_IMPLICIT_IFE_RULES is 1.
*
* By setting USE_IMPLICIT_IFE_RULES to zero (0), the implicit IFEs are disabled
* for all tasks. Tasks will then be considered to have a single instance only,
* covering all execution fragments, unless you define an explicit IFE in each
* task by calling vTraceTaskInstanceIsFinished before the blocking call.

*
* HWTC Macros
*
* These four HWTC macros provides a hardware isolation layer representing a
* generic hardware timer/counter used for driving the operating system tick,
* such as the SysTick feature of ARM Cortex M3/M4, or the PIT of the Atmel
* AT91SAM7X.
*
* HWTC_COUNT: The current value of the counter. This is expected to be reset
* a each tick interrupt. Thus, when the tick handler starts, the counter has
* already wrapped.
*
* HWTC_COUNT_DIRECTION: Should be one of:
* - DIRECTION_INCREMENTING - for hardware timer/counters of incrementing type
* such as the PIT on Atmel AT91SAM7X.
* When the counter value reach HWTC_PERIOD, it is reset to zero and the
* interrupt is signaled.
* - DIRECTION_DECREMENTING - for hardware timer/counters of decrementing type
* such as the SysTick on ARM Cortex M3/M4 chips.
* When the counter value reach 0, it is reset to HWTC_PERIOD and the
* interrupt is signaled.
*
* HWTC_PERIOD: The number of increments or decrements of HWTC_COUNT between
* two tick interrupts. This should preferably be mapped to the reload
* register of the hardware timer, to make it more portable between chips in the
* same family. The macro should in most cases be (reload register + 1).
*
* HWTC_DIVISOR: If the timer frequency is very high, like on the Cortex M chips
* (where the SysTick runs at the core clock frequency), the "differential
* timestamping" used in the recorder will more frequently insert extra XTS
* events to store the timestamps, which increases the event buffer usage.
* In such cases, to reduce the number of XTS events and thereby get longer
* traces, you use HWTC_DIVISOR to scale down the timestamps and frequency.
* Assuming a OS tick rate of 1 KHz, it is suggested to keep the effective timer
* frequency below 65 MHz to avoid an excessive amount of XTS events. Thus, a
* Cortex M chip running at 72 MHZ should use a HWTC_DIVISOR of 2, while a

*
* The Queue Receive Task:
* The queue receive task is implemented by the prvQueueReceiveTask() function
* in this file. prvQueueReceiveTask() sits in a loop where it repeatedly
* blocks on attempts to read data from the queue that was created within
* main_blinky(). When data is received, the task checks the value of the
* data, and if the value equals the expected 100, outputs a message. The
* 'block time' parameter passed to the queue receive function specifies that
* the task should be held in the Blocked state indefinitely to wait for data
* to be available on the queue. The queue receive task will only leave the
* Blocked state when the queue send task writes to the queue. As the queue
* send task writes to the queue every 200 (simulated - see notes above)
* milliseconds, the queue receive task leaves the Blocked state every 200
* milliseconds, and therefore outputs a message every 200 milliseconds.

* NOTE 1: The Win32 port is a simulation (or is that emulation?) only! Do not
* expect to get real time behaviour from the Win32 port or this demo
* application. It is provided as a convenient development and demonstration
* test bed only. This was tested using Windows XP on a dual core laptop.
*
* Windows will not be running the FreeRTOS simulator threads continuously, so
* the timing information in the FreeRTOS+Trace logs have no meaningful units.
* See the documentation page for the Windows simulator for an explanation of
* the slow timing:
* http://www.freertos.org/FreeRTOS-Windows-Simulator-Emulator-for-Visual-Studio-and-Eclipse-MingW.html
* - READ THE WEB DOCUMENTATION FOR THIS PORT FOR MORE INFORMATION ON USING IT -
*
* NOTE 2: This project provides two demo applications. A simple blinky style
* project, and a more comprehensive test and demo application. The
* mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select
* between the two. See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY
* in main.c. This file implements the comprehensive test and demo version.
*
* NOTE 3: This file only contains the source code that is specific to the
* basic demo. Generic functions, such FreeRTOS hook functions, are defined in
* main.c.
*******************************************************************************
*
* main() creates all the demo application tasks, then starts the scheduler.
* The web documentation provides more details of the standard demo application
* tasks, which provide no particular functionality but do provide a good
* example of how to use the FreeRTOS API.
*
* In addition to the standard demo tasks, the following tasks and tests are
* defined and/or created within this file:
*
* "Check" task - This only executes every five seconds but has a high priority
* to ensure it gets processor time. Its main function is to check that all the
* standard demo tasks are still operational. While no errors have been
* discovered the check task will print out "OK" and the current simulated tick
* time. If an error is discovered in the execution of a task then the check
* task will print out an appropriate error message.
