/******************************************************************************
* vTraceEnable(int startOption);
*
* Initializes and optionally starts the trace, depending on the start option.
* To use the trace recorder, the startup must call vTraceEnable before any RTOS
* calls are made (including "create" calls). Three start options are provided:
* 
* TRC_START: Starts the tracing directly. In snapshot mode this allows for 
* starting the trace at any point in your code, assuming vTraceEnable(TRC_INIT)
* has been called in the startup.
* Can also be used for streaming without Tracealyzer control, e.g. to a local
* flash file system (assuming such a "stream port", see trcStreamingPort.h).
* 
* TRC_START_AWAIT_HOST: For streaming mode only. Initializes the trace recorder
* if necessary and waits for a Start command from Tracealyzer ("Start Recording"
* button). This call is intentionally blocking! By calling vTraceEnable with
* this option from the startup code, you start tracing at this point and capture
* the early events.
*
* TRC_INIT: Initializes the trace recorder, but does not start the tracing.
* In snapshot mode, this must be followed by a vTraceEnable(TRC_START) sometime
* later.
*
* Usage examples:
* 
* Snapshot trace, from startup:
* 	<board init>
* 	vTraceEnable(TRC_START);
* 	<RTOS init>
*
* Snapshot trace, from a later point:
* 	<board init>
* 	vTraceEnable(TRC_INIT);
* 	<RTOS init>
* 	...
* 	vTraceEnable(TRC_START); // e.g., in task context, at some relevant event
* 
* Streaming trace, from startup:
*	<board init>	
*	vTraceEnable(TRC_START_AWAIT_HOST); // Blocks!
*	<RTOS init>
*
* Streaming trace, from a later point:
*	<board startup>
*	vTraceEnable(TRC_INIT);
*	<RTOS startup>
*

/******************************************************************************
 * vTracePrintF
 *
 * Generates "User Events", with formatted text and data, similar to a "printf".
 * User Events can be used for very efficient logging from your application code.
 * It is very fast since the actual string formatting is done on the host side, 
 * when the trace is displayed. The execution time is just some microseconds on
 * a 32-bit MCU.
 *
 * User Events are shown as yellow labels in the main trace view of $PNAME.
 *
 * An advantage of User Events is that data can be plotted in the "User Event
 * Signal Plot" view, visualizing any data you log as User Events, discrete
 * states or control system signals (e.g. system inputs or outputs).
 *
 * You may group User Events into User Event Channels. The yellow User Event 
 * labels show the logged string, preceded by the channel name within brackets.
 * 
 * Example:
 *
 *  "[MyChannel] Hello World!"
 *
 * The User Event Channels are shown in the View Filter, which makes it easy to
 * select what User Events you wish to display. User Event Channels are created
 * using xTraceRegisterString().
 *
 * Example:
 *
 *	 traceString adc_uechannel = xTraceRegisterString("ADC User Events");
 *	 ...
 *	 vTracePrintF(adc_uechannel,
 *				 "ADC channel %d: %d volts",
 *				 ch, adc_reading);
 *
 * The following format specifiers are supported in both modes:
 * %d - signed integer. 
 * %u - unsigned integer.
 * %X - hexadecimal, uppercase. 
 * %x - hexadecimal, lowercase.
 * %s - string (see comment below)
 *
 * For integer formats (%d, %u, %x, %X) you may also use width and padding.
 * If using -42 as data argument, two examples are:
 *    "%05d" -> "-0042"
 *     "%5d" -> "  -42".
 *
 * String arguments are supported in both snapshot and streaming, but in streaming
 * mode you need to use xTraceRegisterString and use the returned traceString as
 * the argument. In snapshot you simply provide a char* as argument.
 *
 * Snapshot: vTracePrintF(myChn, "my string: %s", str);
 * Streaming: vTracePrintF(myChn, "my string: %s", xTraceRegisterString(str));
 * 
 * In snapshot mode you can specify 8-bit or 16-bit arguments to reduce RAM usage:
 *     %hd -> 16 bit (h) signed integer (d).
 *     %bu -> 8 bit (b) unsigned integer (u).
 *
 * However, in streaming mode all data arguments are assumed to be 32 bit wide. 
 * Width specifiers (e.g. %hd) are accepted but ignored (%hd treated like %d).
 *
 * The maximum event size also differs between the modes. In streaming this is
 * limited by a maximum payload size of 52 bytes, including format string and
 * data arguments. So if using one data argument, the format string is limited
 * to 48 byte, etc. If this is exceeded,  the format string is truncated and you
 * get a warning in Tracealyzer.
 *
 * In snapshot mode you are limited to maximum 15 arguments, that must not exceed
 * 32 bytes in total (not counting the format string). If exceeded, the recorder
 * logs an internal error (displayed when opening the trace) and stops recording.

 * Note that there is no initialization code that pushed the free handles

 *
 * The stack of handles (objectHandles) is initially all zeros. Since zero
 * is not a valid handle, that is a signal of additional handles needed.
