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. How do I know what pins to use in the initialization code? Can anyone help me to understand how you initialize the SPI? You just need different type of effort. Sign up using Email and Password.

I can successfully program the chip in Atmel Studio, by using a batch file which loads bosssa. 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.

It’s tough for an spu beginner. Post Your Answer Discard 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.

You have two options here. Bence Kaulics 5, 10 23 Finally, you’ll need to configure the SPI peripheral itself. How do I know what pins to use in the initialization code? psi

Thank you for the help!! Can anyone help me to understand how you initialize the SPI?

Email Required, but never shown. Above all, remember that the datasheet is your friend! I wsf intend to bash Atmel, but I have to agree, ahmel documentation has so many lines of invisible ink Sign up using Facebook.

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.

If you’re just starting out, then ASF is the way to go. John August 2 Referring back to the datasheet descriptions of the various hardware registers’ functions will help. 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 sli all of the things I’ve outlined above.

As already mentioned, sp ASF documentation is a complete mess. You just need different type of effort. That may help a lot. In either case, you will have to deal with a lot of things that the Arduino environment handles for si.

As you can see, I don’t have the slightest clue how to go about setting up the SPI interface in Atmel studio.

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 am running Atmel Studio 6.

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. Most pins aymel have many peripherals which can be selected, so you’ll need to set the pin multiplexer to select the proper SPI unit.
