Which the method to monitor the active power from the ADE7758 IC ?
For phase A, i was implemented by follow steps:
1. Set up and wait zero crossing interrupt from phase A.
2. After zero crossing interrupt i will
2.1. read AWATTHR register and store to E variable.
2.2. read FREQ register (result in frequency) and then convert to actual frequency(Hz).
F = FREQ register x 0.0625
T = 1/F
2.3. Calculate P = E / T.
