I'm working on data acquisition from a sensor attached to the Arduino : MPU6050 using a model in Ssimulink. I have installed the hardware support in Simulink but I don't know how to start building the model. The model must read the data from the Arduino by deploying it into the Arduino.

My connection Arduino <=> MPU6050 is :

Arduino    MPU 9150
3.3V       VCC
GND        GND
A5         SCL
A4         SDA
DIGITAL 2  INT
GND        AD0

update : i have use a s-function but I get the following error: _The call to realtime_make_rtw_hook, during the after_make hook generated the following error: Could not download the model to the target hardware. Verify the connection between the computer and target hardware.

The build process will terminate as a result.

Caused by: Could not download the model to the target hardware. Verify the connection between the computer and target hardware._

But the target is definitely connected, and downloading others module (like led blinking ) with simulink is working fine. I've also tested this on a different PC with Windows 8 (64bits) with the same result. Can anyone give me a hint please?
