interrupt service routines while not using epwm modules

Joseph Peter

i am planing to write codes using gpio pins instead of epwm module for space vector PWM in vector control o0f induction mtoro drives ...so while implementing foc algorithm can i use

interrupt void epwm1_isr(void)

{.....

}

for writing the control algorithm ?

Hi Joseph,

I'm not clear here... if you're not using ePWM then why epwm isr? What is main motive or what are you planning to achieve with your ISR?

Regards,
Gautam

HI GAUTAM

MY doubt was whether i can use epwm isr while not using epwm module for implementing foc algorithm inside isr.(calling various functions inside isr)..now i am clear about that

thanks and regards

Joseph,

Yes - you can use EPWM ISR, irrespective of whether you use EPWM outputs on GPIO or not.
