The easiest thing to go quickly is to use i2cset and i2cget.

There are some examples in section 4.19 of the Linux User Guide found: http://support.logicpd.co...talid=0&EntryId=1392

You should be able to read and write the i2c bus.

If you want to see the code for the i2c tools, enter the following:

./ltib -p i2c-tools -m prep

From there, you'll get the source that builds the tools. It should help point you along.
