* ObjectHandleStack
* This data-structure is used to provide a mechanism for 1-byte trace object

* each object class active at any given moment. There can be more "historic"
* objects, that have been deleted - that number is only limited by the size of
* the symbol table.
* Note that handle zero (0) is not used, it is a code for an invalid handle.
*
* This data structure keeps track of the FREE handles, not the handles in use.
* This data structure contains one stack per object class. When a handle is
* allocated to an object, the next free handle is popped from the stack. When
* a handle is released (on object delete), it is pushed back on the stack.
* Note that there is no initialization code that pushed the free handles
* initially, that is not necessary due to the following optimization:
*
* The stack of handles (objectHandles) is initially all zeros. Since zero
* is not a valid handle, that is a signal of additional handles needed.
* If a zero is received when popping a new handle, it is replaced by the
* index of the popped handle instead.

* if higher IRQ priority values means higher priority, this should be 1.
*

*
******************************************************************************
*
* 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 OS 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).
* For FreeRTOS, this can in most cases be defined as
* #define HWTC_PERIOD (configCPU_CLOCK_HZ / configTICK_RATE_HZ)
*
* 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
* faster chip require a higher HWTC_DIVISOR value.
*
* The HWTC macros and vTracePortGetTimeStamp is the main porting issue
* or the trace recorder library. Typically you should not need to change
* the code of vTracePortGetTimeStamp if using the HWTC macros.

* xTraceOpenLabel
*
* Creates user event labels for user event channels or for individual events.
* User events can be used to log application events and data for display in
* the visualization tool. A user event is identified by a label, i.e., a string,
* which is stored in the recorder's symbol table.
* When logging a user event, a numeric handle (reference) to this string is
* used to identify the event. This is obtained by calling
*
* xTraceOpenLabel()
*
* whihc adds the string to the symbol table (if not already present)
* and returns the corresponding handle.
*
* This can be used in two ways:
*
* 1. The handle is looked up every time, when storing the user event.
*
* Example:
* vTraceUserEvent(xTraceOpenLabel("MyUserEvent"));
*
* 2. The label is registered just once, with the handle stored in an
* application variable - much like using a file handle.
*
* Example:
* myEventHandle = xTraceOpenLabel("MyUserEvent");
* ...
* vTraceUserEvent(myEventHandle);
*
* The second option is faster since no lookup is required on each event, and
* therefore recommended for user events that are frequently
* executed and/or located in time-critical code. The lookup operation is
* however fairly fast due to the design of the symbol table.

* vTracePrintF
*
* Advanced user events (Professional Edition only)
*
* Generates User Event with formatted text and data, similar to a "printf".
* It is very fast compared to a normal "printf" since this function only
* stores the arguments. The actual formatting is done
* on the host PC when the trace is displayed in the viewer tool.
*
* User Event labels are created using xTraceOpenLabel.
* Example:
*
* traceLabel adc_uechannel = xTraceOpenLabel("ADC User Events");
* ...
* vTracePrint(adc_uechannel,
* "ADC channel %d: %lf volts",
* ch, (double)adc_reading/(double)scale);
*
* This can be combined into one line, if desired, but this is slower:
*
* vTracePrint(xTraceOpenLabel("ADC User Events"),
* "ADC channel %d: %lf volts",
* ch, (double)adc_reading/(double)scale);
*
* Calling xTraceOpenLabel multiple times will not create duplicate entries, but
* it is of course faster to just do it once, and then keep the handle for later
* use. If you don�t have any data arguments, only a text label/string, it is
* better to use vTraceUserEvent - it is faster.
*
* Format specifiers supported:
* %d - 32 bit signed integer
* %u - 32 bit unsigned integer
* %f - 32 bit float
* %s - string (is copied to the recorder symbol table)
* %hd - 16 bit signed integer
* %hu - 16 bit unsigned integer
* %bd - 8 bit signed integer
* %bu - 8 bit unsigned integer
* %lf - double-precision float (Note! See below...)
*
* Up to 15 data arguments are allowed, with a total size of maximum 32 byte.
* In case this is exceeded, the user event is changed into an error message.
*
* The data is stored in trace buffer, and is packed to allow storing multiple
* smaller data entries in the same 4-byte record, e.g., four 8-bit values.
* A string requires two bytes, as the symbol table is limited to 64K. Storing
* a double (%lf) uses two records, so this is quite costly. Use float (%f)
* unless the higher precision is really necessary.
*
* Note that the double-precision float (%lf) assumes a 64 bit double
* representation. This does not seem to be the case on e.g. PIC24 and PIC32.
* Before using a %lf argument on a 16-bit MCU, please verify that
* "sizeof(double)" actually gives 8 as expected. If not, use %f instead.
