a spi port without sdi would not be a spi port it would be something else.

not sure what you mean by ssp . ss=slave select,its an input pin.
a spi master port has no ss pin there is no such thing as ss out, ss is an optional input signal for spi slave ports.
the master device needs to assign a separate i/o pin as a cs to drive a slaves ss pin if its required. the mssp port does not provide that function.


nice to see you have it up and running, for the record what did you have wrong earlier that stopped it functioning?
