µVISION DEBUGGER: Starting and Stopping Trace Capture

Information in this article applies to:

• µVision Version 2.06

QUESTION

Is there a way in the µVision Debugger to start and stop trace recording dynamically as my program runs? There are only a few places where I want to record the instructions that are executed.

ANSWER

Yes. The µVision Debugger has a System Variable named itrace that you may use to enable or disable trace recording. This trace only works for the simulator and not the monitor debugger (mon51, mon166, mon251). For example:

itrace = 1;  /* Enable Trace Recording */

itrace = 0;  /* Disable Trace Recording */

You may download the µVision Simulator C166 Trace Memory Example attached to this article for a more complete example.
