Hi Deamonata, Thanks for the reply, I've tried changing the variable type to a number of different ones and nothing seems to change. From http://www.nongnu.org/avr-libc/user-manual/group__avr__stdint.html it looks like int16_t (what's currently being used) is a signed integer. Since posting this I've tried using the L3G library (https://github.com/pololu/L3G/tree/master/L3G) and that seems to be giving a more reasonable range. (I thought it was -65,535 to 65536, which is a bit strange so I'll check when I get home, I'm probably mistaken).

Hi, I'm having a bit of trouble understanding the output of the L3G4200D Gyroscope. When I run the sample program I get an output on all axis between 0 and 255. It doesn't seem to distinguish between clockwise rotation and anti-clockwise rotation. Here's an example of the output from running https://github.com/jrowberg/i2cdevlib/blob/master/Arduino/L3G4200D/Examples/L3G4200D_raw/L3G4200D_raw.ino (excluding Serial.print("angular velocity:\t"); ) Does anyone know if this is correct?
