There seem to be a ton of devices available, but the "SPI standard" is not official and implementation varies almost per device. Command word lengths and number vary. Reply now or next bits or byte later varies. it seems, each device needs it's own driver. I did find this driver: http://www.paul.de/downloadables/#spi-driver and learned allot from the documentation and the source. Worth several days (for me at least) of spending free time being anti-social and making LEDs blink.
