Hi all,

I am attempting to generate a sine wave using a lookup table. So far, I have been successful, so now i require to make it 60 Hz. How would I go about changing the frequency?

Hi,

In your current implementation, how are you updating values inside the VDAC ? Are you using a timer ? If you are, you can change the period of the timer to change the generated waveform frequency. The frequency at which will you update will depend, will be dependent on the number of sample points you are using. But make sure that you are not crossing the maximum update rate provided in the datasheet.

Best Regards,
