I am trying to interact with two AD7192 chips via a single SPI master. Right now I have the Din, Dout, and SCLK pins shorted to the same MOSI MISO and SLCK on the master, with GPIOs controlling the CS pins.
From my understanding, the Dout/RDY pin will only go low if the chip is selected with CS. Otherwise, the Dout pin is driven at a high impedance state. This way, I can have a chip selected with CS and monitor its Dout/RDY pin without worrying about it sinking current into the Dout pin of the other AD7192.
Is this correct? I've been having some trouble controlling two AD7192 via a single master and would appreciate any help!
