Shift lower & upper bytes left once (to remove 1 bit space a top of high byte):
Convert from hexadecimal to decimal counts:
X Accel Y Accel Z Accel X angular rate Y angular rate Z angular rate
0 64616 62392 1636 63076 9008
Correct bank, elevation, and angular rates for the sign
If >32767 then subtract 65536 from the data
X Accel Y Accel Z Accel X angular rate Y angular rate Z angular rate
0 -920 -3144 1636 -2460 9008
Convert to units: counts x scale factor
For Bank & Elevation:
Scale factor is: 180 ˚ / 32768 counts
For Heading: Scale factor is: 360 ˚ / 65536 counts
For Accelerations: Scale factor is 10g / 32768 counts
For Angular Rates: Scale factor is: (200 ˚/sec) / 32768 counts
