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.
