Freemaster: Stopped, waiting for acknowledgement

[Sam_ECU]

Hello @MichalH

As discussed in the post below, when using the recorder in Freemaster I receive the message "Stopped, waiting for acknowledgement" once the measurement is finished.  I then don't get any results.

I'm working with the MCU below:

I'm using the latest version of Freemaster:

How can I resolve the issue?

Thanks for the help,

Sam

Hello Sam,

In general, a similar recorder behavior can be seen when FMSTR_Recorder() is not called periodically by the MCU application - so its state machine is not running. 

I see that you use the Matlab Model-based design toolbox. I'm not an expert here, but I think the "Recorder Call" should be put in a block which is triggered periodically, e.g. by an interrupt. You can check the generated C code to see how is the FMSTR_Recorder() called.

I also recommend to refer to a MBDT Motor Control demo which makes use of an interrupt-driven recorder. If you need a further help, I will ask someone from MBDT team to step in. 

Regards,
Michal

Hello Michal,

I had it located within an atomic system, that appears to have been the issue.

Thanks,

Hello Sam,
Would you please share the detail information about how you solve the issue. I met the same issue in MBDT.

It's been awhile but I believe the Recoder-Block needed to be on the front page of Simulink and not within any function or atomic blocks.

OK, thanks for info. Please mark the answer above as 'correct' to close this thread.

Thank you,
