C2000 multiple SPI device control

Other Parts Discussed in Thread: ADS131M08

Hi,


We recently received a question about controlling two ADS131M08 devices with a C2000 microcontroller. For this microcontroller there are two SPI modules, and they'd like to know if they can be controlled at the same time, so that they receive commands at the same time, and read data such that the devices are synchronized.

I suspect they can't be run simultaneously, but we did suggest an alternate, where one SPI module acts as a master to send commands to both devices, but reads data from device #1. A second SPI module acts as a slave and reads the data from device number #2.

The original post can be found here:

Regardless, can you comment on either setup or mode of operation? I'm not sure which C2000 device is being used. If you want, I can have the post moved here.
