peripheral pin select for SPI

[David Stephenson]

I'm having trouble understanding how use the PPS to assign pins to for SPI communication.
I am using a 16F18326. The assignment of SCK and SDO seem normal, but how do I assign the SDI to a pin?

The Send me a personal message.. I will send you the new PpSTool for GCB. It due for release next week but if you take the release candidate.. It has the tool included.

Pete Everett has developed and it is very very simple.   We will formally launch next week.

tool will set the port up with ease.

Meanwhile for record, a working example, this is for the Ethernet Adapater.

This is direct from the new tool.

The tool seems to work nicely.
Seems I was getting confused with uni-directional and b-directional pins.
I take it the SS pin does not have to be specified through the PPS settings.

[Anobium]

Really pleased the tool worked.

Any changes recommended? Please send via a email.

Correct - SS pin does not have to be specified through the PPS settings.
