hello friends
I have a arduino due 2 mcp3208 and 5 mcp4922.
so i have to read 10 Analog channel and write 10 Analog channel.
(for 0v to 5V communication i used also Adum1401 digital isolator)
so my question is that arduino due capable to communicate single spi channel to multiple in may case 7 slave?
Hi,
Welcome to the forum.
Please read the post at the start of any forum , entitled "How to use this Forum".

This is what SPI is designed for, connecting many devices to the controller with the least amount of wiring.
The Due already has 11 analog inputs.
Have you got any of the hardware, if so start connecting it together on protoboard and writing some code.
Can you tell us your electronics, programming, arduino, hardware experience?
Thanks.. Tom... 
Hey Tom thanks for your reply,
Actually i have a tested with one mcp2308 and one mcp4922. and i also get my result. so now i have to design PCB for 10 input and output thats why i have a question is that working to multiple salve with arduino due.
because i have read that arduino due multiple slave working with only 4,10 and 52 no arduino pin.
You can choose any pin for CS providing you handle manually set/clear pin states. Only 40,10 and 52 pins can be handled automatically by the SPI peripheral.
Oh thanks brother it's working!!
