Alain,

Thanks for your post. Any chance of seeing your program for the 5534. Particularly the I2C comms bit?

I've got mine running but the calibration coefficients are nothing like the published example. I'm wondering if:

1. My code is wrong, or
2. My level conversion is wrong?

Don't bother with the code - I've just got mine working.

Pull-up resistor on the SCL line was poorly connected.

The bi-directional level conversion described in the Philips application note works fine with a 2N7000 MOSFET.
