ATMEL ASF SPI DRIVER

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. That may help a lot. You have two options here. Post as a guest Name. 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.

As already mentioned, the ASF documentation is a complete mess. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

It’s tough for an absolute beginner. Post as a guest Name. Many MCUs of this class will have several SPI units, and the datasheet will specify which pins can be used by which unit. As you can see, I don’t have the slightest clue how to go about setting up the SPI interface in Atmel atmep.

That may help a lot. I soi running Atmel Studio 6. Home Questions Tags Users Unanswered. If you’re just starting out, then ASF is the way to go. Referring back to the datasheet descriptions of the various hardware registers’ functions will help. 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 zsf Arduino Due schematics to figure out which pins you’ll need to use for SPI and what clock settings are appropriate.

In either case, you will have to deal with a lot of things that the Arduino environment handles for you. You just need different type of effort.

Above all, remember that the datasheet is your friend! Sign up using Email and Password.

Finally, you’ll need to configure the SPI peripheral itself. Sign up or log in Sign up using Google. Most pins will have many peripherals which can be selected, so you’ll need to set the pin multiplexer to select the proper SPI qtmel.

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.

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. I don’t intend to bash Atmel, but I have to agree, their documentation has so many lines of invisible ink Anyway, to answer the question: 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.

Thank you for the xtmel
