Hello,

I have a project using both keyboard and USB storage capability of the 32u4 chipset on the new arduino boards (maybe a Pro Mini from sparkfun) and I'd like to add a flash memory chip, not big 4mb would be plenty to store a file enven when unpluged, and I can't find any hookup guide and library that could be useful for me, any ressources ?

I'd like to use one of those chips A25L080-F

OK I've checked it out and undestrand how it works but this doesn't tell me how to wire the SPI chip to my arduino... that's the part I'm the most worried about, the code won't be that much of a deal.

Any diagrams to wire the chip ?
