Hi, I have been working with an AD9525 which is connected in 4 wire SPI mode.
I am having trouble communicating with the device. From what I understand I first need to set the SDO active bit in the SPI mode register. So the SPI transaction would be 3 bytes or 0x00 -> 0x00 -> 0x81. However after I complete this step, The SDO line never seems to become active during later read attempts. Should this be all that there it to it? Or have I overlooked something.
Thanks in advance.
