CC3220MOD: C3220MOD

Part Number: CC3220MOD

I want to use C3220MOD as a slave controller which would communicate using SPI to a master controller. But I have another device AS8510 which has to send the data to C3220MOD and it supports SPI communication. Can the microcontroller C3220MOD act as a slave (for the master controller) and master (for AS8510) as there is only 1 SPI available using C3220MOD?

    Hi Radhika,

    CC3220 can work as both master and slave but not at the same time. You'll need to close the interface and open it in a different role.
    In addition, I guess you'll need some external mux to switch between the master controller and the AS8510 whenever the role are switched (otherwise you'll end up with 2 masters on the a single bus).
    So basically, the requirement is the entire system will be synchronized.
