Is that an I2C device? I had a very quick look a the data sheet and see it's a 2-wire, it looks like I2C, but they seem to carefully avoid calling it that - which suggests that it is "I2C compatible" but perhaps not officially licensed for using that term from Philips? I haven't compared all of the protocol to make sure. Are yo just using I2C routines to talk to it? Dale -- It's a thankless job, but I've got a lot of Karma to burn off.
