/*
This is an INS driver for the combination L3G4200D gyro and ADXL345 accelerometer.
This combination is available as a cheap 10DOF sensor on ebay
This sensor driver is an example only - it should not be used in any
serious autopilot as the latencies on I2C prevent good timing at
high sample rates. It is useful when doing an initial port of
ardupilot to a board where only I2C is available, and a cheap sensor
can be used.
Datasheets:
