I am doing a project in which I want to measure active power of the 3 phases. For this I think the process is
1) Specify through SPI which register you want to read
2) Get the value of that register through SPI
In this way keep getting the data. Am I missing on some important part in monitoring the power? As in, is this method wrong?
Also could you explain why calibration is needed before I use the IC on a PCB with MCU for the final project?
