3.4 Test code example
Code example is available to download from a WEB (USB2CAN_TEST.py)
Two CAN bus interfaces need to be connected on same computer together (Ex.: connect two USB2CAN
usb ports to a computer and connect can ports together). The code sends random from one interface to
another and checks if the
received data is valid.
To use the code go to terminal and launch command:
python USB2CAN_TEST [can interface 1] [can interface 2] [number of packets] [baudrate]
Example to send 100 random data packets from interface can0 to can1 at a 125 Kbps baudrate:
python USB2CAN_TEST.py can0 can1 100 125000
Testing was done using Ubuntu Linux distribution. Other distributions may require additional configuration.
