EVAL-CN0326-PMDZ SPI COMMUNICATION PROBLEM

Now I'm getting status code 0x88 on first read without any delay after bus reset.Previously i was using 1 second deay after reset. But after first read im getting 0x48 from status register ie; error bit is being set. Other registers are giving some random value when read without reset. 

Hi,

What is the setting of you SPI channel?

for your future reference, here is a sample C code from Github using ADICUP3029:

Currently i a'm interfacing with the AD7793 directly by soldering wires on the board. Everything is working fine when interfacing directly. That means SPI communication is proper

This is my SPI settings

Hi NousharNajeeb,

If you are still having an issue with the communication line, I do suggest to lower the speed of the spi clock to prevent from getting a random value.  Since the digital isolator ADUM5401(Mfg P/N: ADUM5401ARWZ) used in this eval board is an A grade which has only 1Mbps data rate.

Cheers,
