Hi everyone,

I am using MATLAB 2017a for code generation for C2000 controllers and wanted to implement ePWM. Having searched web for ePWM, I found few examples on MATLAB website which can be opened by entering a command in command window like:

c28035pfc.slx

DCDC_Buck_Sim.mdl

c28x7x_c28004x_dma_epwm

So when I type these commands in window, it returns me the error: No system or file called 'xyz' found.

Can someone help me?

Regards

As per my understanding, I think the example that you looked up might be shipped with a different version of Matlab, that might be the reason for that error.
