Hi, we're working on a Thermistor sensing application and I had some questions about the AD7791's SPI bus, can this device be used on a shared SPI bus? I think that the RDY pin would cause issues with other devices on the bus?
Does the Linux driver support reading from the AD7791 with it sharing a bus without the RDY interrupt causing issues?Thanks
As far as I can tell, there is no reason why you cannot have multiple devices on the same SPI bus, as long as they do not share the same CS.
The DOUT/RDY goes low to indicate the completion of a conversion, but this will not happen unless CS goes low first.
