The PEAK PCAN-RS-232 is a programmable module for the communication between RS-232 and CAN. The device is based on the NXP LPC21 series microcontroller which handles conversion of data traffic between the two bus systems. 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. The PCAN-RS-232 ships with a pre-installed demo firmware that routes data from CAN to RS-232 and vice versa. Both the data transfer and the hardware can be configured with serial control commands. The corresponding source code is included as an example in the scope of supply.
