If you’re just starting out, then ASF is the way to go. I can successfully program the chip in Atmel Studio, by using a batch file which loads bosssa. Post as a guest Name. I don’t intend to bash Atmel, but I have to agree, their documentation has so many lines of invisible ink 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.

Many MCUs of this class will have several SPI units, and the datasheet will specify which pins can be used by which unit.

In either case, you will have to deal with a lot of things that the Af environment handles for you.

How do I know what pins to use in the initialization code? Sign up using Email and Password. 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. There are examples in the ASF documentation 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.

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. Post as a guest Name. Can anyone help me to understand how you initialize the SPI?

Email Required, but never shown.

Referring back to the datasheet descriptions of the various hardware registers’ functions will help. As you can see, I don’t have the xpi clue how to go about setting up the SPI interface in Atmel studio.

You have two options here. 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 quicker 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.

That may help a lot. Sign up or log in Sign up using Google. You just need different type of effort. Thank you for the sli I don’t intend to bash Atmel, but I have to agree, their documentation has so many lines of invisible ink Finally, you’ll need to configure the SPI peripheral itself.

Bence Kaulics 5, 10 23 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.

Anyway, to answer the question: However, the ASF documentation does an exceptionally 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 doing.

Most pins will have many peripherals atme can be selected, so you’ll need to set the pin multiplexer to select axf proper SPI unit. 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! Check out this post for details:
