vector interface raise exception: XL_ERR_WRONG_PARAMETER #208

Closed daily2008 closed 6 years ago

daily2008 commented 6 years ago

Hi, when I use the vector inferface, it raise execption as: File "D:\SVN\linux_svn\trunk\brilliance_m8x\robot\src\lib\TACommonLib\Python_CAN_Library\can\interfaces\vector\canlib.py", line 85, in init vxlapi.XL_INTERFACE_VERSION, vxlapi.XL_BUS_TYPE_CAN) File "D:\SVN\linux_svn\trunk\brilliance_m8x\robot\src\lib\TACommonLib\Python_CAN_Library\can\interfaces\vector\vxlapi.py", line 74, in check_status raise VectorError(result, xlGetErrorString(result).decode()) VectorError: XL_ERR_WRONG_PARAMETER

I have already use PCAN interface and it works ok. So I just change following settings for my scripts: 1) change parameter interface="vector", channel="0,1,2,3" 2) connect Vector CAN/LIN interface VN1640A hardware to PC. So are there any else problems for my settings? I have read the "XL Driver Library - Description.pdf", it mentioned need do some configuration with "Vector hardware config tool", I'm not sure these configurations must be done manually before running scripts? thank you very much!

You should run Vector hardware config tool and check the configuration for CANalyzer, if it exists. Otherwise you must create an application, assign your channels, then specify app_name="Your application" to your Bus constructor.
