I know eCosCentric have one, but you need to pay for that. Other people have mentioned writing i2c drivers as well. However, you need to be careful. The i2c hardware is broken. The Linux kernel marks it as such. See: http://www.at91.com/samphpbb/viewtopic.php?t=4665&sid=1032a7cdc95b571dc784adb204d78d33 >From what i understand, if you are doing transfers of 1 byte, it is O.K, but multiple byte transfers can break. Writing a GPIO based driver should be reasonably easy as far as i understand and does not suffer from these problems. Andrew
