Hello,
I have a big problem Arduino 101, i have bought a I2C module and I want to connect with display 2004A.
I already have a day when try to solve this problem.
I don't now which library to use, library Wire.h don't show on board Arduino 101 but on another shows...
I have connect pins on Arduino 101:
SDA -> SDA
SCL -> SCL
I am a beginner and i don't now how to programming it ...
Can you help me please ... 
Thank you very much!!!
Hi VDionis,
all Arduino libraries are intended to be cross platform, so if you know the display producer you'll be able to find a compatible library using Library manager.
As far as I know, TC2004A always exposes all pins (https://cdn-shop.adafruit.com/datasheets/TC2004A-01.pdf) so you can use the standard LiquidCrystal library. In case your display only exposes I2C interface, try taking a look at LiquidCrystalI2C library and see if it applies.
