This is regarding voltage and current harmonic calculation using ADE7758 by acquiring waveform samples from the waveform register
(1) I could acquire the voltage waveform samples (with datarate 3.25kSPS), but, how to get the samples at the exact instant.
eg: for a 50Hz signal, and if 32 samples has to be sampled per cycle - samples are required every 625us. (0.625ms, 1.25ms, 1.875ms, ....)
Even if I enable the WFSM interrupt after a specific interval, wouldn't there always be a slight delay in getting the sample after enabling it?
(2) I am getting a distorted wave when trying to reconstruct waveform from current samples(The voltage waveform samples are fine).
CTs are used for current sensing.
Looking forward to your reply.
