Hi,
I am using STM32F407VET6 IC to measure 3 Phase AC voltage,Phase Angle, Frequency PF,Current.
now i am trying to measure AC voltage using ADC,(stepping down AC voltage and measuring the voltage with ADC by sampling and averaging).
and Timer channel input capture mode to measure the Phase angle and frequency
using above method if i need to measure both voltage and the Phase angle. I need 6 pins to measure voltage and angle for single phase. Incase of 3 phase i need 18 pins to do the same.
is it possible to measure both AC voltage and phase angle using single ADC input?
kindly guide me to the better solution.
Thanks
M.Govind
