I also had to modify spacepoint.py to from "import hid" to "import libhid.hid as hid" The Ubuntu package is slightly different than the source release.

In order to get the accelerometer values in g's I had to multiply the raw values by 16 in addition to your arithmetic. But the gyros are still a mystery. The raw values are not described in the doc. Do you know their scale? Their center doesn't seem to be 32768, but about 500 less. If I use their initial values as the center, they seem to give degrees/sec, but that is only a guess. I emailed pni but no reply yet. Yes everything works. In order to get the accelerometer values in g’s I had to multiply the raw values by 16 in addition to your arithmetic.

If I want to access the raw sensor data instead of the calculated data, I must just change the 0x82 flag to 0x81 right? Hey thanks a lot, this is very cool.
