Vector XL Driver Library Wrapper for Python.

• Vector XL Driver Library inlclude dlls for C/C++, C# but not for Python.
• pyxldrv makes the dll for C/C++ an importable library(vxlapi).
  • To wrap C/C++ dll, pyxldrv uses Cython.
  • Cython generates a library for Python("vxlapi.xxxxxx.pyd") from Cython codes(vxlapi.pxd and vxlapi.pyx).

import vxlapi as xl

ret = xl.OpenDriver()
....
msgs = []
msgs.append({"flags":0, "id":0x321, "dlc":8, "data":bytearray([0x12,0x34,0x56,0x78,0x9A,0xBC,0xDE,0xF0])})
message_count = [len(msgs)]
status = xl.CanTransmit(portHandle[0], accessMask, message_count, msgs)
...
ret = xl.CloseDriver()

• and there is an additional wrapper class for CAN(can.py).

• Get XL Driver Library and Vector Driver Setup from Vector Download-Center and install them.

• Get Cython via pip at first.

• For Python 3.6

  • Get Build Tools for Visual Studio 2017.

For debugging vxlapi.pyx, DebugView for Windows can be used. Because DebugView for Windows shows native side(vxlapi.dll) function's status, "debug print" can be reduced.

See XL Driver Library - Description.pdf
