Micro C/OS-II realtime response measurement

There are some scope probes in here showing the interrupt timing of an ARM micro. You can do the same for a NIOS processor:

Hi jayze_ng,

I've done something like you want with Oscilloscope.

Start synchro on INT event and show a change output pin of FPGA on the second curve.

And done it several times to have good statistics.

The INT in my software set a flag and another task is OSflagPending this flag.

Hope it helps you.

Thanks a lot Dave @ bvincent1, it really help in observe the time response. Million thanks for your resourse and idea. :)

Hi Dave and bvincent1,

Do you guys ever tried uc/probe before? As i found that this software was quite good in term of real time measurement.

No, it did not exist when I was developing with uCOS-II (for a TI DSP).

I did look at it when I installed uCOS-III for one of the book editions (STM development kit, I think) for a friend. I have the TI ARM EVALBOT so will look at it one day using that.

Good to know, thanks!
