Hi, I'm a newbie so excuse the dumb question. Trying to implement an
SPI interface between one master and multiple slaves. One of the slaves
is on an external board and i've only got 3 pins available for
connection to Master board(Its a PCB and i'm adding this slave). Now,
the SPI interface requires 4-wires(I need the Slave Select) if the
slave is "transmit only" can i leave the SDI pin unconnected (Datasheet
doesn't say much)??
P.Sevices are pics.
Thanks
