TMS320F28335: While using multiple Hardware interrupt in a Matlab code I am getting this error "only one instance of hardware interrupt is allowed in a model". How can i access multiple Hardware interrupts?

Ankita Dhiman

Part Number: TMS320F28335

Tool/software:

I am using DSP F28335 for running my hardware. For my hardware setup i need multiple interrupt each one dedicated to one separate subsystem.

For sensing the inputs i am using ADC interrupt (SOC EPWM_A_EPWM_B) and after sensing the signals i need to make three subsystem that will take some ADC inputs to generate PWM. Each of this subsystem is triggered using one Hardware interrupt from EPWM blocks. But I am not able to access multiple interrupt, it is showing error " only one instance of hardware interrupt is allowed in a model".

How can i have this separate interrupt for each subsystem?

I have attached the trigger pattern and my code structure as well. EPWM interrupts ADC Interrupts Code Trigger structure

Hello,

Please take a look at MathWorks FAQ at this link below:

If you have further questions, the best way to get support on MathWorks products is to contact MathWorks live tech support.

You can also search for answers or post a question on MATLAB Answers C2000 forum. Additionally, there is info on MathWorks support C2000 in Documentation and Examples.

I will close the thread from here as the software is supported by MathWorks team on their forum.

Regards,

Subham
