How to Measure FPS and CPU usage with Qt for MCUs

s.a.m

Hello everybody,

I am using STM32H750B-Disco board, and I designed a simple demo with Qt Creator and was able to successfully build and run it on my STM32H750B-Disco board.
And now, I want to measure the FPS and CPU usage of this demo on my board so I can evaluate it better;

I searched a lot in the documents and even examples and codes, But didn't found anything about CPU usage at all,
About FPS I was able to found "QulPerf" from this page of the documents;
But the problem about this is it doesn't work for me at all, "QulPerf.enabled" is false for me although I tried to compile the application with QUL_ENABLE_PERFORMANCE_LOGGING as well; this part of the doc is not clear for me anyways:

This data is only available if Qt Quick Ultralite is compiled with QUL_ENABLE_PERFORMANCE_LOGGING

And it doesn't exactly say how to compile with QUL_ENABLE_PERFORMANCE_LOGGING, as result "QulPerf.fps" shows 0 to me all the time;

I will be very thankful if somebody corrects me and helps me out about these two issues.
Thanks in advance,
Best regards.

Hi @s-a-m, and welcome!

Few members on this community forum have access to Qt for MCUs because it is a commercial-only product. If you don't get an answer here, I suggest you open a commercial support ticket to receive help from MCU experts.

@JKSH Thanks for clarify and quick answer!

In fact I'm using 10-days trial license for now, to evaluate Qt for MCU first and then Buy it, So is that possible for me to open a support ticket and get help from MCU experts in this situation?

I believe your trial license entitles you to official support while your license is active.

Have a look at https://account.qt.io/support -- if you signed up for a trial license the website should let you submit a support request

@JKSH Yes I have access to submit a support question, but in the "Request type" field I can only select "Account questions" and "Sales question" and there is no "Technical support" option.
Can I ask my question under one of those two types? That's not a problem?

Ah, that's unfortunate.

I think it doesn't hurt to try. You'll either get an answer or get "Sorry, we can't offer support here"

@JKSH Yes I tried my chance yesterday! Hopefully, I'll get a useful answer.
Thanks for all your helps anyways, much appreciated;
btw, If I didn't get an answer, Are there another way to ask or not?
