I jumped into reading this note without looking at the url or author and near the end I was wondering who wrote it -- Then I saw the reference to the SPI driver which was a dead give away for James Bowman. I am continuously impressed with his work in the embedded scene after discovering the gameduino. It feels like even though there are thousands of voices on the web I actually only care about what perhaps 50 people are writing.
