 *
 * A group of Macros which should be defined as an integer value of zero (0) 
 * or larger.
 *
 * This defines the capacity of the Object Property Table - the maximum number
 * of objects active at any given point within each object class.
 * 
 * NOTE: In case objects are deleted and created during runtime, this setting
 * does not limit the total amount of objects, only the number of concurrently
 * active objects. 
 *
 * Using too small values will give an error message through the vTraceError
 * routine, which makes the error message appear when opening the trace data
 * in FreeRTOS+Trace. If you are using the recorder status monitor task,
 * any error messages are displayed in console prints, assuming that the
 * print macro has been defined properly (vConsolePrintMessage). 
 *
 * It can be wise to start with very large values for these constants, 
 * unless you are very confident on these numbers. Then do a recording and
 * check the actual usage in FreeRTOS+Trace. This is shown by selecting
 * View -> Trace Details -> Resource Usage -> Object Table
 * 
 * NOTE 2: Remember to account for all tasks created by FreeRTOS, such as the 
 * IDLE task, the FreeRTOS timer task, and any tasks created by other 3rd party 
 * software components, such as communication stacks. The recorder also has an 
 * optional monitor task to account for, if this is used.
 * Moreover, one task slot is used to indicate "(startup)", i.e., a fictive 
 * task that represent the time before the FreeRTOS scheduler starts. 
 * NTask should thus be at least 2-3 slots larger than your application task count.
 *
 * NOTE 3: The FreeRTOS timer task creates a Queue, that should be accounted 
 * for in NQueue.

 * RECORDER_STORE_MODE
 *
 * Macro which should be defined as one of:
 * - STORE_MODE_RING_BUFFER
 * - STORE_MODE_STOP_WHEN_FULL
 * Default is STORE_MODE_RING_BUFFER.
 *
 * With RECORDER_STORE_MODE set to 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 STORE_MODE_RING_BUFFER, you need to first halt the
 * system using your debugger and then do a RAM dump, or to explicitly stop the
 * recorder using vTraceStop() and then store/upload the trace data using a
 * FreeRTOS task that you need to provide yourself. The trace data is found in
 * the struct RecorderData, initialized in trcBase.c.
 *
 * Note that, if you upload the trace using a RAM dump, i.e., when the system is 
 * halted on a breakpoint or by a debugger command, there is no need to stop the 
 * recorder first.
 *
 * When RECORDER_STORE_MODE is STORE_MODE_STOP_WHEN_FULL, the recording is
 * stopped when the buffer becomes full. When the recorder stops itself this way
 * vTracePortEnd() is called which allows for custom actions, such as triggering
 * a task that stores the trace buffer, i.e., in case taking a RAM dump
 * using an on-chip debugger is not possible. In the Windows port, vTracePortEnd
 * saves the trace to file directly, but this is not recommended in a real-time
 * system since the scheduler is blocked during the processing of vTracePortEnd.

/******************************************************************************
 * USE_IMPLICIT_IFE_RULES
 *
 * Macro which should be defined as either zero (0) or one (1).

 *
 * ### 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. FreeRTOS+Trace 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 following FreeRTOS kernel calls
 * are considered by default to be IFEs (Implicit IFEs):
 *  - vTaskDelay
 *  - vTaskDelayUntil
 *  - vTaskSuspend
 *  - xQueueReceive (blocking cases only)
 *  - xSemaphoreTake (blocking cases only)
 *
 * However, Implicit IFEs only applies to blocking kernel calls. If an
 * xQueueReceive 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 such as
 * xQueueSend or xSemaphoreGive. 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 like
 * vTaskDelay, 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.
