Syntax

stopProfiler(target_object)

Description

stopProfiler(target_object) stops the profiler from running on the Speedgoat® target computer.

If the profiler collected data, the data is available for download to the MATLAB® development computer.

If the profiler did not collect data, the profiler is ready to restart.

If you stop execution of the real-time application, the profiler stops.

When the profiler starts and stops, there is an increase in task execution time (TET) that can cause a CPU overload condition. If using profiler causes CPU overload, you can increase the sample time in order to use the profiler.

Start the profiler, and then start the real-time application. After collecting execution profile data, stop the profiler.

  1. tg = slrealtime;
mdlSTF = getSTFName(tg);
mdlName = 'slrt_ex_mds_and_tasks';
mdlNameSub1 = 'slrt_ex_mds_subsystem1';
mdlNameSub2 = 'slrt_ex_mds_subsystem2';
openExample(mdlName);
open_system(mdlNameSub1);
open_system(mdlNameSub2);
set_param(mdlName,"SystemTargetFile",mdlSTF);
set_param(mdlNameSub1,"SystemTargetFile",mdlSTF);
set_param(mdlNameSub2,"SystemTargetFile",mdlSTF);
slbuild(mdlName);
load(tg,mdlName);
startProfiler(tg);

% start profiler before starting application

start(tg);

% let application run until its stop time
% or stop the profiler by calling stopProfiler

stopProfiler(tg);

  2. At this point, call either the getProfilerData function or the resetProfiler function.
