PCAN-GPS – User Manual

Introduction
The PCAN-GPS is a programmable sensor module for position and
orientation determination. It has a satellite receiver, a magnetic field
sensor, an accelerometer, and a gyroscope. The sampled data can
be transmitted on a CAN bus and logged on the internal memory
card. The data processing is performed by a microcontroller of the
NXP LPC4000 series.
Using the supplied library and the Yagarto GNU ARM toolchain
(contains the GNU Compiler Collection GCC for C and C++), custom
firmware can be created and then transferred to the module via
CAN. This gives a whole range of options for manipulation,
evaluation, filtering, and routing of the data traffic.
On delivery, the PCAN-GPS is provided with a demo firmware that
transmits the raw data of the sensors periodically on the CAN bus.
The source code of the demo firmware as well as further
programming examples are included in the scope of supply.
