I am working with the ADE7880 ADC and am attempting to initialize it and use it to read and write registers via SPI in C on a Linux system. My goal is to capture ADC data through SPI, but I am encountering difficulties.

Here are the specifics of my issue:

1. I have written to 4 registers to initialize the ADC.

2. I am trying to read data from a specific register, but I am not receiving the expected default data or the data I wrote.

I am unsure if the ADC is being initialized correctly or if the data is being read properly.

I referred to this link for guidance, but I am still experiencing issues.

Could someone please provide assistance or suggest what might be going wrong? Any help would be greatly appreciated!

Thank you!
