This are some simple examples to test the communication between twoCAN channels.1) receive: polling mode receiving end2) transmit polling mode transmitter3) baud    simple driver test: change the bit rate registers with ioctl()    the change itself stays after program is finished.    you can check it by read    cat /proc/sys/Can/Baud    before and after using this command4) acceptance    simple driver test: change the message filter with ioctl()    the change itself stays after program is finished.    you can check it by read    cat /proc/sys/Can/AccCode /proc/sys/Can/AccMask    before and after using this command5) noiser    a simple noise transmitter, generates messages with random    CAN IDs and telegram content    useful for filter testing 6) can_send    simple command line tool for sending single or    cyclic CAN messages    can_send -h   tells you all    some special test-sequences are build-in7) ctest    very simple and basic driver test    I use it to see what the driver issues in /var/log/messages    when open and close the device.    If full debug is enabled and all register access is logged8) receive-select    simple receiving using the select() call to wait for CAN messages Support and examples for Scripting Languages==============================================canLtwo.c 	simple CAN Layer-2 interface, C-SourcecanLtwo.i  	simple CAN Layer-2 interface, SWIG-Interface file
