Scripts to interface with CAN bus devices using CANtact and Pyvit
Note: uses can0 and /dev/ttyACM0
Initialize CANtact with:
python init.py
To display messages on the bus in realtime (Frame ID, packet data):
python socketCAN.py [options]
To display messages on the bus filtered by IDs according to packets in comands_db.json. Scans bus only for IDs in .json file.
python socketCAN_json.py
To send a single CAN frame onto the bus:
cansend can0 123#1122334455667788
will send a message on interface can0 with identifier 0x123 and data bytes [0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88]. This too assumes values are given in decimal.
To send CAN frames onto the bus using scripts:
python socketsend.py
To request sensor queries according to OBD command tables:
python obd_query.py
To generate random CAN data, useful for testing:
cangen can0
