Hi,
I hava a Simulink-Model containing some Sensor-Calibration, Calculation and PID-Controlers and am currently compiling it for my TI F28335 DSP. I get the *.out-File and run it on my DSP. That is working fine.
Now I would like to tune the parameters and see the variables in real time. I think the term for this is "Hardware in the loop". I have installed various versions of Matlab, CCS, CGT and Bios. I am not completely sure which combination is best but it seems that R2016a and CCS6 can work together.
I also would like to know: What are the differences between SiL, PiL and external mode? Which one is best for my application?
Can I use my JTAG-Connection on the XDS100v2-Debug-Probe or do I have to connect via SCI?
Thank you very much in advance!

Hi Martin,
External mode is what you are looking for. It is supported over serial and CAN on the C2000 processors. Here is a detailed example on how to get started:
https://www.mathworks.com/help/supportpkg/texasinstrumentsc2000/examples/parameter-tuning-and-signal-logging-with-serial-external-mode.html
Make sure that you have a proper serial connection in place, these pages can help you establish your serial communication:

I hope it helps,
Antonin.

Set the four pin pins of boot to SCI inF28335？choose GPIO28/29？

Hey Antonin,
thank you very much for your links, I am sorry the problem must be somewhere else. I can compile and send the code to target (DSP) but not start the simulation.
Best regards, Martin

a) The target is not switched on.
b) The target is not connected to your host machine.
c) The application for the model is not running on the target. You might have clicked the Stop button. If the Run button is not dimmed, click it. Otherwise, click the Build button, which downloads and runs your application on the target.

Hi Martin,
i know this answer is a bit late but i got the same problem today and maybe someone else needs the solution too.
Did you set your Simulation stop time to inf? In my case the Simulation stop time was set to 10 seconds and it seems that it started to count down although it wasn't even connected to the board. When it was ready to connect, the Simulation stop time already was over and i got the same error-message as you did. So i set the Simulation Stop time to inf, then it worked.
Best regards, Michael

Thank you very much for your answer. My Problem was, that there is no SCI connection on this XDS 100 v2-Debug Probe. Now that I have connected my SCI using another cable, it works.
