Is ir possiple to use a SPI device with AT91FR40162? How can I interface them?

Thanks

That part does not have a hardware SPI.

To implement SPI you would need to use software SPI with some GPIO. There are a number of sources for examples, though most are for the 8 bit world. Might consider looking at avrfreaks.org for their software SPI examples.

Hi, I had the same problem....I wrote a software SPI driver which uses no timers. It runs at 5Mhz (thats the fastest I could produse) on my AT91FR40162 at 66MHz, compiled with GreenHills Multi.
If you're interested, I can post my code.

i am interested.
can you send me an e-mail with your code?

Hi,

Please find attached my code.....

The code can handle all 4 spi modes. Currently there is a write and write/read function. The read only function is not implemented (yet).
The data width is currently maximum 32bits (a unsigned32), I thing enough for most devices...

the code worked already on different spi devices...

I used following pins:
Clock : PIO__P16
Data In: PIO__P17
Data out: PIO__P18

For the chip select we used some hardware to handle this which was connected to the data/address bus, so this is the only thing you must change.
Change this in the define : #define SET_CS(_number)

I use GreenHills Multi, compiled with this I get 5MHz!!! which is fast for software SPI...I compiled with the space optimize (not the speed), looking at the generated assembler, this was the best result. The c-code is optimized with defines!

If you should have any questions, don't hesitate to contact me.

PS : whats the weather there? I once went to Sao Paolo for the Ford/Renault...
