You can manually set the configuration registers directly for the SPI peripheral, or you can use the “Atmel Software Framework” which abstracts a lot of the details into a higher-level API. Home Questions Tags Users Unanswered.

Many MCUs of this class will have several SPI units, and the datasheet will specify which pins can be used by which unit. Most pins will have many peripherals which can be selected, so you’ll need to set the pin multiplexer to select the proper SPI unit.

I don’t intend to bash Atmel, but I have to agree, their documentation has so many lines of invisible ink Though, experienced developers say that beginners should go with ASF which is actually trueit doesn’t mean that you can achieve with less effort the same thing. As aymel can see, I don’t have the slightest clue how to go about setting up the SPI interface in Atmel studio.

You have two options here. There are examples in the ASF asc linked in previous comments that should help you out, and if you examine them closely you should see that the example applications do all of the things I’ve outlined above. It’s so difficult to work out what is being driven, what you have to provide to configure the drivers, and what they actually do that it’s actually sspi just to read the datasheet and write your own drivers particularly when you don’t need all the configuration complexity and can just hardwire in the settings you need.

So all of that is a very general answer–your specific solution will depend on the particular hardware setup you have, so you’ll need to look at the Arduino Due schematics to figure out which pins you’ll need to use for SPI and what clock settings are appropriate.

Post as a guest Name. However, the ASF documentation does an aatmel poor job of actually explaining what’s going on and why, so you’ll need to carefully study the MCU datasheet sections on clock, power management, GPIO, and SPI to really figure out what you’re dpi.

Email Required, but never shown. I can successfully program the chip in Atmel Studio, by using a batch file which loads bosssa.

Above all, remember that the datasheet is your friend! Sign up using Facebook. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

John August 2 Unfortunately the datasheet also does a poor job of explaining how peripherals are meant to be used, so some reading between the lines will be required. I am running Atmel Studio 6. Anyway, to answer the question: If you’re just starting out, then ASF is the way to go. In either case, you will have to deal with a lot of things that the Xpi environment handles for you.

That may help a lot. As already mentioned, the ASF documentation is a complete mess. Check out this post for details: Referring back to the datasheet descriptions of the various hardware registers’ functions will help.

Finally, you’ll need to configure the SPI peripheral itself.
