Wondering about SPI...

Erik "SPIN" J.

Hi everyone, I have a question about SPI. Is it possible to parallel-connect the DI, DO, and CLK lines of multiple devices, and use the CS lines to assert which device you wish to communicate with? For example,
P0 = HM55B CS
P1 = SD CS
P2 = Shared DI
P3 = Shared DO
P4 = Shared CLK
Thanks in advance, Erik

Whaddya say we take this lil' chip for a SPIN?

Yep, that will work just fine!
