Yep, Also along the same line, an actual one from Adafruit for the Raspberry PI. (I have one of these bouncing around here somewhere)
I just hooked up one of these to my Raspberry Pi CM dev kit.
I am quite impressed on their work for this. I also ran it on the arietta G25 (its a 400mhz) board and works smoothly there as well.
Check out the video on this page.
What i just cant wrap my head around is the Edison is faster than the G25 & on top of this has 2 cores. Why is the Edisons SPI so lame?
I have given up on it. The CS - CS delays are killing me with it, and i cannot find any reason why this is.
