Version 0.1 (Commit 64e4388 of June 3, 2021):

  • CAN 2.0:
    • 11-bit and 29-bit identifier
    • bit-rates up to 1’000 kbps
  • Bit-rate settings:
    • via register values (clock, prescaler, time segment TSeg1 and TSeg2, SJW, SAM)
    • as pre-defined bit-timing index (according to CiA CANopen specification)
  • Operation modes:
    • Monitor mode enable/disable (default=disabled)
    • Error frames enable/disable (default=disabled)
    • Extended frames disable/enable (default=enabled)
    • Remote frames disable/enable (default=enabled)
  • Message reception:
    • Message queue (FIFO) for 64K CAN message
    • Read queue via polling, blocking read, or with time-out up to 65 seconds
  • Message transmission:
    • with or without acknowledge (with time-out up to 65 seconds)
  • Application Programming Interface:
    • CAN API V3 by UV Software (C and C++ API)
    • CAN API V3 Python Wrapper (Python 2.7 and 3.8)
  • Supported Kvaser CAN Leaf devices:
    • Kvaser Leaf Light v2 (EAN: 73-30130-00685-0)
    • Kvaser Leaf Pro HS v2 (EAN: 73-30130-00843-4)
  • Limitations (selected):
    • Leaf Pro HS v2 devices can currently only be operated in CAN 2.0 mode!
    • Monitor mode (listen-only) is not supported by the Leaf Light v2 hardware.
