Vector CAN not able to communicate

[Hitayukta]

Hello all,

I have installed Python can on Windows 10. This machine has a vector CAN (VN5620) XL driver and VN5620 drivers installed.

This is my can.conf file

This is my channel mapping in vector Canoe tool

I use CAN1 VN5620 1 Channel 5 in my Canoe

When I run this command:

with can.Bus() as bus: ... for msg in bus: ... print(msg.data)

I get error:

Traceback (most recent call last): File "", line 1, in File "C:\Users\lp91kor.conda\envs\CANfuzzing\lib\site-packages\can\interface.py", line 127, in new bus = cls(channel, *args, **kwargs) File "C:\Users\lp91kor.conda\envs\CANfuzzing\lib\site-packages\can\util.py", line 337, in wrapper return f(*args, **kwargs) File "C:\Users\lp91kor.conda\envs\CANfuzzing\lib\site-packages\can\interfaces\vector\canlib.py", line 187, in init channel_index = self._find_global_channel_idx( File "C:\Users\lp91kor.conda\envs\CANfuzzing\lib\site-packages\can\interfaces\vector\canlib.py", line 361, in _find_global_channel_idx hw_type, hw_index, hw_channel = self.get_application_config( File "C:\Users\lp91kor.conda\envs\CANfuzzing\lib\site-packages\can\interfaces\vector\canlib.py", line 868, in get_application_config raise VectorInitializationError( can.interfaces.vector.exceptions.VectorInitializationError: xlGetApplConfig failed (Vector HW Config: Channel '5' of application 'python-can' is not assigned to any interface) [Error Code 255]

Can anyone help me resolve this issue ?

Note I have installed all the vector can drivers on this machine. Thanks

Vector HW Config: Channel '5' of application 'python-can' is not assigned to any interface

That's your problem. With vector interface you have three options:

1. Connect via the global channel index: channel=4, app_name=None
2. Connect via Vector HW Config channel assignment: channel=0, app_name="python-can. But here you need to assign Channel 1 of app 'python-can' to VN5620 Channel 5
3. Connect via serial: channel=4, serial=2483

Hello,

Thanks for the feedback, I did not understand your solution. Sorry. I want to transmit and receive some data on this and be able to see the CAN bits in the Canoe simulation.

Channel Mapping [https://pasteboard.co/qpGityy3OFys.png]

I changed the can.conf and still see the same error.

[zariiii9003]

try this

[default]
interface = vector
channel = 4
serial = 2483
app_name = python-can
bitrate = 500000

[Hitayukta]

Does not work, sorry

Screenshot : Error_Screenshot

Edit:

I tried with all channels, none of them are working :(

[zariiii9003]

Can you show a screenshot of your Vector Hardware Config? Was your VN5620 connected during your last test?

[Hitayukta]

Yes, it was connected during the last test. The Canoe was running. I always run the Canoe and execute these scripts. Pardon me, I am new to this and do not know stuffs.

[zariiii9003]

Your traceback shows, that serial 2483 was not found. I asked for a screenshot of your Vector HW configuration to be sure that it is connected as you say.

[Hitayukta]

It's a remote setup located outside my scope. However we can still debug. Will post screenshots next week. Thanks a lot for support.

[Hitayukta]

@zariiii9003 - I think I understood the problem. This is my can.conf file.

I created a python-can application in vector hardware config and assigned CAN1 to it. Below screenshot. Vector-hardware-config

After this step. I sent some data on the CAN bus and it says the message was sent on CAN1. CAN1_msg_sent But now, how do I validate what ever I have sent is being sent on CAN1.

CANOE is not running now.

I ran this program, but its still waiting for some thing :(

with can.Bus() as bus: for msg in bus: print(msg.data)
