SEN0590 Laser Distance Sensor

Hi,

I've bought a Sen0590 Laser Distance Sensor but am having trouble getting it to work using Python on a Raspberry-Pi. The datasheet gives C code for the Arduino, I've tried converting this to Python which should theoretically work on the Pi but I'm only getting readings of [255,255].

Has anyone else managed to get it to work ? I have done similar things before so am familiar with switching on the i2c interface etc.

Or does anyone have a more detailed datasheet which states exactly what data needs to be sent/received ?

Thanks !
