Grove LCD RGB Display on Imp003

Is there a library to use a Grove LCD RGB (from seed studio) Display on an imp003 board?

I got this LCD Display --> and i want to make it works on the Imp 003 -->

I connect the SDA and SCL on i2cAB Pins and i`m using an external source for the 5v for the VCC because the imp only got 3.3v.

I allready test the Display on a raspberry (works with python library), but for the Imp (Squirrel Code) i cant find any library to use it or an example code to test it.

anyone have some code that helps?
