Do a search on the forum for *2543*.

You'll find some code for TLC2543 which appears to be the same part in a different package.

The code's for SPI serial interface rather than I2C.

Should get you off the ground, if it's so urgent.

Didn't take too long to find code, and data sheets for both parts on Google.

Quicker that waiting for somebody to do it for you.

and....

You'll actually LEARN how to write real code like 'drivers', which should impress your schoolmates and teacher.

The more code you really cut, the better and faster programmer you become.

Just remember to select the correct pullup resistors for the I2C bus based on speed, Vdd, etc. (all in the datasheets).
