Documentation for SPI on the Nano is inconsistent

[scottchiefbaker]

I use SPI to drive an LED Matrix on my Uno with no problems. I'd like to migrate that project to a Nano but the documentation is inconsistent on SPI support on the Nano. They both have the atmega328 so I assume they're the same?

The documentation for the Uno says:

SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication using the SPI library.

The documentation for the Nano says:

SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the Arduino language.

Documentation should be updated to reflect the correct and current status of SPI on the Nano.

The nano and Uno are indeed pretty much identical in this regard, so I suppose that the nano documentation is simply ancient and predates the SPI software support.

You should be able to use a nano without problems, and Arduino should update the documentation :-)
