Reply To: interface an Arduino Uno as an i2c slave to EV3?

why do you ask? you should know it, we already discussed this beyond measure –
For the EV3 there is no complete C-based API available – no sensor- and no i2c library, just a Lego lms2012 header which is bugged like hell.
I also don’t understand anything about C#, Visual Studio, WiFi, classes, objects, implementing, derivating, uses, extending –
just know something about straight procedures and functions like by ANSI C or Sketch or Pascal. OOP is simply a mess to me.

But the NXC code and the Sketch code (both actually simplified procedural C) have been established by me, top-down, within a couple of days (as you know).

If I knew how to do it by C# I wouldn’t have started my thread about Brick/Arduino-i2c-communication.

But as you are experienced in C# – : if it was that easy, why didn’t you proceed with your beginnings ?
Where’s the coding problem ?
