how to take many samples of voltages or current within a PWM cycle

Hi Waseem,

So if I'm not wrong your PWM triggers ADC conversion right? If so, only one sample per cycle is possible; though you can input the same to multiple ADC channels to get multiple samples in a single PWM cycle.

Thanks Gautam

Can you illustrate this as i am new to this field.

I need to sample voltages at t=0, t= duty cycle . t=half of duty cycle etc.

Any link that can help me understand that interupts as i am not able to comprehend from TI manual

Regards

Waseem

Waseem, which controller are you working on or wish to work on? This would make it easy for me to suggest you the doc to refer.

So did you refer "TMS320x280x, 2801x, 2804x System Control and Interrupts Reference Guide (Rev. H) " doc?
