Hello,
I'm working with eZdsp F28335 Controller and with Matlab Simulink (IDE CCSv3.3)
I have an extern signal source (5kHz PWM) and would synchronize the ePWM Moduls on two diffrent F28335 Controller.
Is this possible ?
On the ePWM Moduls I tick the "Add S/W sync input port" (Input port appears).
Than I connect the GPIO(20) Input (external PWM) with the Sync Input port of the ePWM in my Model.
After that i run the Programm on two diffrent F28335 DSP and connect the external PWM on GPIO(20).
But if i display the two PWM Signal on an oscilloscope the two PWM would be phase shifted.
Please help me.
Best Regards
Dennis
I also find this interesting.
Any news about it Dennis? Although shifted, does the shift drift or is it constant?
For cases where the hardware sync isn't available this really could come in handy if it works propperly.
Best regards,
Martin
