Ok, that's what I understood. Adding appropriate comments to the code to
describe this would be really helpful.

Very good, I just have one last comment:

That no longer needs to be static.
The rest of the code looks fine to me. Once you remove that static
definition, and you add some comments explaining why you need those 3 i2c
pointers, I'll merge it.

Thanks for your work.
