I am working on a metering application where I have STPM10 metering chip connected to the SPI interface of SAMD21(Custom board), I am able to read RMS Voltage and Current values along with the Line Frequency successfully. The device is also capable of readings Active Apparent and Reactive Energies, however it is not very clear to me how these reading can be read as there are internal energy up/down counters which hold a very small energy value and it has to be further integrated inside the application.
If there is anyone her who has experience with this device, please share your experience.
I will appreciate your support.
Best regards, Owais.
