USB-to-CAN V2 LIN interface programming in Linux


#1

Is the LIN interface on the USB-to-CAN V2 Automotive programmable in Linux. (Are there drivers and APIs for Linux?)


#2

Hello,

Yes the USB to CAN has Linux support with our API and drivers.

You should be able to find more info on the following site.

The site mentions APIs and drivers for the CAN interface, but does not mention anything about the LIN interface for Linux.

Hello,

So we support LIN with the USB to CAN. https://www.ixxat.com/products/products-industrial/pc-interfaces/pc-can-interfaces/details-pc-can-interfaces/usb-to-can-v2

We also support Linux with the ECI drivers. https://www.ixxat.com/support/file-and-documents-download/drivers/eci-driver#jump1

Best regards,

Hi Deryck, Altran,
I continue the thread as I dont see in the linux code the part for LIN support yet.
We have purchased a “USB-to-CAN v2 automative” and I see the can0/can1 interface after loading the module from https://www.ixxat.com/support/file-and-documents-download/drivers/socketcan-driver
I may miss something on the way to get LIN interface suppport for Linux.
Much regards,
Xavier.

Hello Deryck,
I have been building “Linux ECI drivers” where I see code to support LIN controller for “USB-to-CAN v2” and enabled the LIN demo but when running the “ECI Demo” I get the following error :
"

It looks like it cannot detect correctly the LIN interfaces of the device ?
Much regards,
Xavier.

Hello @xcarcelle,

Discussing this with my colleague in Germany we are not sure what would be causing this issue. We will need to see if we can recreate the error with the ECI Demo.

  1. Can you test with this driver: ECI_Driver_1.12.3366.0_20190415_Linux_amd64 ?

  1. Could the customer please test if the LIN successfully run with USB-to-CAN V2 under Windows using canAnalyser V3 mini?
    (please note, the LIN transceiver needs an external power)

  2. Were you able to use the Lin controller before? Is this a new device?
    Maybe the LIN controller got broken?

Hello @xcarcelle,

Were you able to test with the driver provided above?
