I have built a prototype project using a Uno. It uses SPI to communicate with a display. However the same project with a Leonardo does not work because the SPI header does not connect to the Digital pins 10-13. I presume I can use the SPI connector but I would rather use the regular pins.
I am now looking at using a Nano and wonder if this will have the same problem.
The Nano page on the Arduino website says the following:
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.
I don't really understand what they mean by the Arduino language in this context because surely the language is the same for all boards.
Can someone explain?
