You sure about that read?

Me wondering why it did not work on my shiny Apalis T30.

Yeah, that one just did not wana set anything (;-p).

Hehe... this should probably be i2c_write() instead. Perhaps this is on by default on Beaver and Cardhu but not on the particular revision that Apalis T30 uses?

Can you test whether things start working if you turn that into a write instead?
