I'm working on a circuit with ADE7953 with I2C bus, I'm using a 0.02 ohms shunt to measure currents.
Some times ago I received some help from Dlath and others and I resolved many problems on my design.
Now I'm communicating with the device but I have some problems.
For example, when i read the Vrms register (0x21C) the value returned is not constant as I expect.
It is changing continously and I don't understand why!
I have one doubt about my design (again!):
My doubt is about the VN and VP pin connections.
This is my configuration:
VP is connected via a 1M resistor to the neutral line and a RC filter to HGND (phase);
VN is simply connected to an RC filter to HGND (phase).
Now the doubt: maybe I need to connect VN directly to HGND (phase) ? But in this case I should remove the RC filter.
What do you think about it?
