SPI usage

Hello,

is there an example how to use the SPI interface? In the documentation I found:

5.10 SPI
On J10 (PicoMOD7-SKIT) you find MISO,MOSI,SPCK and PCS0 SPI lines. A simple demo application
can be found in the download section of PicoMOD7.

But there's no example in the download area. Maybe in PicoMOD6 downloads there's such an example but I cannot access this area.

Thanks in advance.

I created a device:

Then I use the open/read/write functions to deal with "/dev/spidev".

The

function is returning plausible values (8.25 MHz).

The read command is blocking eternaly (I have to power off the device) even if the O_NONBLOCK flag is set in the open function.
Is it possible to use SPI as a slave ?

Any ideas ?
