Cyton & Diasy Schematic

Hi,

I have a few queries on the ADS1299 connection to PIC32. There are 2 ADS1299 - the cyton is master and daisy is a slave. With PIC32 acting as Master - Cyton ADS1299 will be Slave1 and Daisy ADS1299 as Slave 2.

In this case, if both the ADS had to function simultaneously (where Daisy CLK will be grounded, therefore both ADS runs on the CYTON ADS CLK (as suggested in your docs)). Now I would like to know how both ADS (MOSI (PIN34) and MISO (PIN43) are connected to PIC32 (MOSI (PIN3) and MISO(PIN22).

ADS_CYTON - MOSI to PIC32 MOSI
ADS_DAISY - MOSI to PIC32 MOSI
ADS_CYTON - MISO to PIC MISO
ADS_DIAYS - MISO to PIC MISO

Meaning both ADS get directly connected to the PIC for simultaneous processing.
or
ADS_CYTON - MOSI to PIC32 MOSI
ADS_CYTON - MISO to ADS_DAISY MOSI
ADS_DAISY - MISO to PIC MISO

Please suggest the best connection for both ADS to work simultaneously with microcontroller.

Looking forward to a suggestion.
