I need to sample a signal multiple times (10 times) in a switching cycle set by PWM and thereafter calculate its average.

I want to know how to enable multiple sampling. Approach or Any sample code ?

Thanks

Hi Ahmad,

Have you downloaded the Header and Examples for F280x devices already? http://www.ti.com/tool/sprc191

If so, could you take a look at the adc_soc example and see if it fits your requirements for me?

Directory Location: \280x, 2801x Software\c28\DSP280x\v170\DSP280x_examples_ccsv4\adc_soc

This example triggers the ADC to be sampled at a rate defined by an ePWM. After a certain number of samples (say 10) you could call an averaging function within the main loop for the 10 samples. Is this what you're looking for or something else?

Hope this helps,
Kevin

Also, you may want to look at processors.wiki.ti.com/.../C2000_Archived_Workshops for the F2808 Multi-Day Workshop. I know that the labs are based on CCS 3.3, but the Student Guide is excellent in its treatment of PWM and ADC.
