Category: Hardware
Product Number: AD7779

Microcontroller is Connected the EVAL-AD7779FMCZ.

SPI bus is in FULL Duplex mode; Write/Read response from AD7779 is always 0x2000.

Able to toggle the GPIO's of AD7779, but read response is always 0x2000.

Write operation is successful.

Σ-Δ Output Data is also coming as 0x2000.

Thanks,

Darshan.
