A word of caution. The Linux kernel guys consider the AT91 I2C device to be FUBAR. http://cateee.net/lkddb/web-lkddb/I2C_AT91.html http://www.mail-archive.com/[email protected]/msg24797.html http://www.mail-archive.com/[email protected]/msg02209.html I think it is O.K. for single byte transfers, but anything more than that could lead to problems.
