I want to connect some sensor via I2C. As I understand the I2C connectors are connected to the CPU (area U1). I guess this means there is no need to run things over RemoveDevice() in C#. I found https://github.com/Microsoft/Windows-un ... ta.xaml.cs as example. I guess I can access them directly through this lib, but what are the addresse? Can find anything on that.
Thx in advance
Connect to I2C

I gues the above link to Windows IoT Core is a wrong hint. The IoT Core Image does not exist for LP.
Please Lattapanda team explain this part:
Please Lattapanda team explain this part:
How can we write to I2C via RemoteWiring when I2C is placed in area U1 which is not connected to ATmega32u4? Can you please provide some example?Windows Remote Arduino enables the following functionality out of the box:
1. GPIO – Analog and Digital I/O * digitalWrite - Digital Write * digitalRead - Digital Read * analogWrite - Analog Write * analogRead - Analog Read * pinMode - Set the mode for any pins. * Eventing - receive events when values change / are reported 2. I2C/TwoWire * Send/Receive data to and from other devices over I2C 3. Custom protocols via Firmata SysEx command
I think, there are 4 different I2C-Interfaces :
I2C-0, I2C-2, I2C-DDIO on 10-pin-header connected to the CPU
I2C on 24-pin-header connected to Arduino-D2 and -D3 (Meant by Lattepanda team in the quote ?)
( http://www.lattepanda.com/docs/#Connect ... ral_device )
Additional question : What voltage level is used on the CPU-I2Cs ?
Maybe 1,8V and we need level shifter IC ?
Or the CPU-I2C-Pins are 5V tolerant (I don't think so) ?

I still would be intereste in some info to connect to the I2C directly. I guess the way over RemoteWiring won't work either right now thanks to this littel bug viewtopic.php?f=6&t=209.
Somehow disappointing experience working whith this little device...

Maybe not a complete example, but a link to a page with explanations

sorry for delayed response, guys. we will get some documentation up in due course.
Enjoy Tinkering with LattePanda ! 
There is some example of using I2C without arduino (Atom Z8300 has it`s own I2C interface)

I believe the problem is USB/Serial driver support for the Arduino Leonardo board under the .NET core framework i.e. the IOT sample quoted should work on Windows 10 if LattePanda/Microsoft fixed the USB support. Until then, we are stuck with Arduino scripts and wpf/winforms serial communications using System.IO.Ports i.e. the old System.Core
