TMS320F280025C: Using Simulink, Configuring the ePWMx TBPHS via Input port does not work, but using dialog box does

Jeffrey Holt

Part Number: TMS320F280025C

I am using ePWM1-ePWM4 on a F280025C LaunchPad using Simulink Embedded Coder. All PWMs are 50% duty cycle, 200kHz and sync'd.

I would like to be able to control the phase shift of ePWM3 and ePWM4. I can get the phase shift by configuring ePWM3 and ePWM4 using the TBPHS dialog box. However, when I set the TBPHS to be set by an Input port, I am not getting any phase shift no matter what value I provide at the input port.

Is there something else that needs configuration to use the Input? Thanks!

Hi,

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.

Thanks & Regards,

Santosh
