I am trying to calibrate ADE7953 using internal registers , but I have several problems.
the first problem that I want to ask about its reason, the calibration registers responds when I send them values or read values from them, but they show me wrong values for Vrms, Energy, Current etc... all of these values are absolute zeros!
to be sure that there is no problem in connection, I tried to read CONFIG (address 0x102) and it responds with the correct default configuration value (0x8004) , but all registers that are dedicated to have the value of measured variables, equal 0.
what is the source of this problem? is there register that needs to contain certain value to activate the measurement registers?
