Error in compiling #7

Hello,

I'm getting an error when I got to verify the sketch in Arduino - any thoughts?

`sketch/inv_mpu.cpp:50:0: warning: "min" redefined

define min(a,b) ((a<b)?a:b)

In file included from sketch/I2Cdev.h:77:0, from sketch/inv_mpu.h:24, from sketch/inv_mpu.cpp:25: /private/var/folders/yt/fhd66_9n1qq7dtkgr5vr8g880000gn/T/AppTranslocation/ED2C9ABF-55B7-4361-9AA9-AE220C41465E/d/Arduino.app/Contents/Java/hardware/arduino/avr/cores/arduino/Arduino.h:92:0: note: this is the location of the previous definition

Hi,

it's just a warning. The min() function is redefined in the InvenSense code. It does not stop the Arduino project from compiling and the HT works fine with it. I think I will keep it this way, just in case someone would like to reuse the InvenSense code on a different platform than Arduino.

Best, T.
