I2C blues

Has anybody out there interfaced an SRF08 ultrasonic rangefinder
(I2C interface) to a 68HC912DP256B? I'm trying but without success!
Any help is appreciated.

Thanks in advance,
Ron

Since the answer appears to be "no", let's start from the beginning.
First, who makes it?
Second, disconnect the SRF08, and any other parts that may be on the I2C
link except the processor.
Third put a scope on the I2C instead. A storage scope, if you have one.
What do you expect to see?
Run the program.
What do you really see?
Report back here.
