HI

I user ADE7880 initialization encounter a problem.

I took the daatsheet page-75 to set , but all measured data is wrong (rms, active, reactive, and apparent powers.........)

What reasons can cause this kind of state?

Serial Interface Choice

Second, execute three SPI write operations to a location in the

address space that is not allocated to a specific ADE7880 register

(for example 0xEBFF, where eight bit writes can be executed).

These writes allow the SS/HSA pin to toggle three times. See the

SPI Write Operation section for details on the write protocol

involved.
