I have written a short program using the Codevision AVR C-compiler (version
1.25.8a) to communicate between an ATMega128 and an electronic compass chip
using the I2C (inter-integrated-circuit) functions in Codevision.

So far, no luck. I have followed the example shown in the CV-AVR Help file.
Using an oscilloscope, I do not see any activity at either of the Mega128
ports that I have designated for I2C communication.

Has anyone else used the Codevision compiler's I2C functions and been
successful?

I have described my problem in an email to Pavel Haiduc at HPInfoTech
(author of Codevision) but he has not yet responded.
