a similar problem came up in this forum, however i couldn't find a working solution for me.
The Problem is the SPI communication with the AD7124-4 at 3.3V.
I use the following setup:
AVDD = IOVDD = 3.3 V
AVSS = DGND = GND
When i run the setup at 3.3 V i get the following signals on the SPI when i try to read the IDRegister:
If i use 3V instead, i get the following signals:
And i get the expected answer of 0x02 when reading the IDRegister.
Thanks in advance
