Sampling a 100 Hz sinwave at a frequency of 1000 Hz is not a good idea (10 points per period is a bit weak). You won't see a nice sinewave output from the DAC.

I would go for at least 60 points per period.

Thank you for your reply, actually this is for an experiment so i need to see the steps ! but for sure this is not a good sinewave fron the DAC

I have one additional question, in that case (the timer drives the ADC), does it mean that the ADC_clock = sampling frequency ?

If not how can i know the ADC_clock ?


Thank you
