ATMEL ASF SPI DRIVER

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. Thank you for the help!! John August 2 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 the Arduino Due schematics to figure out which pins you’ll need to use for SPI and what clock settings are appropriate. 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.

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. Home Questions Tags Users Unanswered. I am running Atmel Studio 6. Many MCUs of this class will have several SPI units, and the datasheet will specify which pins can be used by which unit.

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.

You just need different type of effort.

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. Above all, atmmel that the datasheet is your friend!

Thank you for the help!! 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 don’t intend to bash Atmel, but I have to agree, xpi documentation has so many lines of invisible ink As already mentioned, the ASF documentation is a complete mess.

If you’re just starting out, then ASF is the way to go.

John August 2 As you can atmfl, I don’t have the slightest clue how to go about setting up the SPI interface in Atmel studio. Bence Kaulics 5, 10 23 I can successfully program the chip in Atmel Studio, by using a batch file which loads bosssa.

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.

Post as a guest Name. Finally, you’ll need to configure the SPI peripheral itself. 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.

Can anyone help me to understand how you initialize the SPI? It’s so difficult to work out what is being asv, 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.

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. Email Required, but never shown. It’s tough for an absolute beginner. That may help a lot.
