PWM.zip

My simulink model is generating a PWM signal with a duty cycle indicated by the constant block.

It works fine when I deploy to hardware, but is not working when I try it in external mode. I want to modify the duty cycle while it is running.

This is what I have set in configuration parameters;

I am attaching the simulink model as a zip file too.

Any help would be appreciated.

Hi,

There is a check box (Boot from flash) in the first image file that you have attached. Please enable the check box and try to run in external mode. I tried your model and could update the duty cycle and the only change I did is enable the check box.

Regards,

Hello,

I have enabled the Boot from flash option and tried running in external mode but I have the following error message

That was the only thing I changed, but it is still not working for me.

Thanks in advance for the help.

Regards.

Hello,

Mi problem appears to be fixed. I can now run in external mode and tune the duty cycle while running. What I did was to reinstall CCS with an older version, the 7.4 as that is the one compatible with Matlab R2018a according to what I read in another post here. There is detail and that is that I still have error messages when enabling the Boot from flash box, so I do not have that enabled at the moment, but I can run in external mode.
