C. The figure below shows the
ARM board connecting an IMU-3000 evaluation board to a Windows PC. (Note that the ARM board is used
as a general-purpose bridge and can also be used with other InvenSense EVBs, including the ITG-3xxx and
MPU-3xxx family of devices.) The ARM processor on the reference board is not meant to be reprogrammed
by the user. It contains all code necessary to be used in conjunction InvenSense evaluation boards. Note
that separate demonstration software may accompany the individual evaluation boards with which this
device connects.
