The PCAN-GPS made by PEAK-System Technik (Germany) is a programmable sensor module for position and orientation determination. The unit has a satellite receiver, a magnetic field sensor, an accelerometer, and a gyroscope. The acquired data can be transmitted on a CAN bus and logged on the internal memory card. The integrated NXP LPC4000 series microcontroller performs all the data processing.
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 over the CAN bus. The option of using user-designed firmware gives a whole range of possibilities for manipulation, evaluation, filtering, and routing of the data traffic.
Upon delivery the PCAN-GPS is pre-loaded 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.
