Plc IDE I2C communication

Hello!

Is there some sort of documentation on how to get the I2C communication running over the grove port?
I think it is only possible via sketch and I tried using the wire.h library and checking wire, wire1 and wire2. I find some slaves on wire and wire1 but my device is not there.
I might have some issues with the electrical connection as I have to use a level shifter to get to 5v but I just want to confirm that I basically just have to communicate over wire.h?

Thanks!

I think I2C comms is just done over the SDA and SCL connectors.

I'm merely a noob on the Arduino but i indeed do believe wire.h should be enough for comms over I2C, but i will no doubt be corrected by someone smarter if i'm wrong.

It is however important to use the correct identifier address for your device 0x??.
If you don't it will not recognise the device i think.

Let me know how you get on, always interested to learn as well.
