QSPY  5.8.0
Revision History

Version 5.7.0, 2016-09-08

Corrected QSPY software tracing host application to properly display floating point numbers in user-defined trace records (QS_F32() and QS_F64() macros). Corrected QSPY software racing host application to properly display floating point numbers in user-defined trace records (QS_F32() and QS_F64() macros). The problem was with incompatibility between Microsoft VC++ and GCC floating-point format specifications. In the GCC software build (which produces the QSPY executable in the qtools/bin directory), the MS-VC++ floating point format resulted in all zeros (e.g., 0.0000e+000).

Version 5.6.4, 2016-05-04

Added QWIN GUI to the collection (sub-directory qwin_gui).

Updated the QSPY software tracing host application for the QS trace record name changes introduced in QP 5.6.2.

Version 5.5.0, 2015-08-21

Extended the QSPY software tracing host application for bi-directional communication with embedded targets (output and input into the target). Added a UDP socket to QSPY, as an extensibility mechanism for adding external GUIs and/or scripts to control the embedded targets.

Provided new QSpyView Tcl/Tk extension of the QSPY host application for control testing, and visualization of the real-time tracing data from embedded targets at real-time. QSpyView enables developers to rapidly build both GUI-based and "headless" scripts for their specific applications (see http://www.state-machine.com/qpc/arm-cm_dpp_ek-tm4c123gxl.html)

Version 5.3.1, 2014-04-21

Corrected the version representation from hex to decimal, to match the change in the QP framework. The version representation missmatch caused problems in parsing newly modified trace records, when the qspy.c implementation was inserted directly into the projects.

Version 5.3.0, 2014-03-31

Added new trace records to QSPY host application: QS_QEP_TRAN_HIST, QS_QEP_TRAN_EP, and QS_QEP_TRAN_XP. Changed labels for standard records from Q_ENTRY, Q_EXIT, Q_INIT to ENTRY, EXIT, INIT.

Version 5.1.1, 2013-10-15

Fixed the bug in the QSPY host application, which didn't handle correctly object/functions/signal names longer than 32 characters. The name limit has been raised to 64 characters and this version also correctly truncates the names at the limit without printing any garbage characters.

Version 5.1.0a, 2013-09-18

Modified QSPY utility to support changes in QP 5.1.x:

-improved handling of target resets by adding an empty QS record before the QS_QP_RESET record. The empty record provides the frame delimiter in case the last record in incomplete, so that the following QS_QP_RESET record can be recognized.

-improved hanlding of internal object/function/signal dictionaries so that symbolic information is displayd for all occurrences of an object/function/signal, for which a dictionary record was received.

Version 5.0.0a, 2013-09-08

Modified QSPY utility to support changes in QP 5.0.x:

-modified the standard trace records QS_QF_TICK, and QS_QF_TIMEEVT_* to contain the tick-rate number.

-added trace records QS_TEST_RUN and QS_TEST_FAIL for unit testing.

-added version compatibility level 5.0, whereas specifying version -v 4.5 runs qspy in the compatibility mode with QP 4.5.x.

-added Find And Replace Text (FART) utility for Windows

Version 4.5.02, 2012-07-21

Re-designed the QSPY interface to support more flexible parsing of the trace records in desktop-based simulations (such as Windows or Qt). Users can provide a custom parsing callback function to QSPY_config(). Also added QS_RESET() macro to reset the internal dictionaries (and other cleanup in the future) when the target resets.

Version 4.5.01, 2012-06-25

Added the QS_USR_DICTIONARY() entry for storing dictionaries of the user trace records. Replaced all remaining sprintf() calls with snprintf().

Version 4.5.00, 2012-05-26

Re-designed the implementation of the QSPY host application, so that it can be convenienty included as part of the QP library. This allows direct QS tracing output to the screen for QP applications running on the desktop. The QSPY application has been converted from C++ to plain C for easier integration with QP/C.

Version 4.3.00, 2011-11-03

This QSPY version mataches the changes to the critical section macros made in QP 4.3.00. The QS record names QS_QF_INT_LOCK and QS_QF_INT_UNLOCK have been replaced with QS_QF_CRIT_ENTRY and QS_QF_CRIT_EXIT, respectively.

Version 4.2.04, 2011-09-27

This QSPY version fixes the bug of incorrect reporting function or object pointers for which the dictionary records are not provided and which are repeated in one format line (bug #3405904). For example, trace record AO.FIFO would report (incorrectly) as follows:

0014004078 AO.FIFO: Sndr=200009B4 Obj=200009B4 Evt(Sig=00000009,Obj=200009B4, Pool= 0, Ref= 0) Queue(nFree= 5, nMin= 5)

The Sndr= and Obj= are reported to be the same, but they were not.

Version 4.2.01, 2011-08-01

This QSPY version adds generation of sequence diagrams as files to be processed by MscGen (www.mcternan.me.uk/mscgen/). This version adds the option -g<msc_file> to generate .msc file.

Also, this version of QSPY for Windows allows COM ports larger than COM9.

Version 4.2.00, 2011-07-13

This QSPY version matches the changes made to QS target code in QP/C/C++ 4.2.xx. These changes include sending the additinal byte of sender priority in trace records:


Additional changes include sending the poolID and refCtr of events in two bytes instead of just one byte. The changes affect the following trace records:

  • QS_QF_GC.

Also, for compatibility with the QP 4.2.xx, this version changes the defaults as follows:

signal size (-S) from 1 byte to 2 bytes, and

baud rate (-b) from 38400 to 115200

This version adds the following trace record:


The version also adds compatiblity with 64-bit targets (such as 64-bit linux). This version can accept 8-byte pointers (both object pointers and function pointers) as well as 64-bit integers sent in user-defined trace records.

This version also adds the hex format for uint32_t integers sent in the user-defined trace records.

Finally, this version adds command-line option -v to specify the corresponding QP version running on the target. The default version is -v4.2, but by specifying version -v4.1 or -v4.0 will switch QSPY into the backwards-compatibility mode with the earlier versions of QP.

Version 4.1.06, 2011-02-09

This is the intial standalone release of the QSPY host application. QSPY is still available in the QP/C and QP/C++ distributions, but other rapid prototyping platforms (such as mbed or Arduino) do not use the standard QP distributions and have no easy access to the QSPY tool. For these users, this pre-compiled standalone release is more convenient.
