Hello,
I am new in this forum. I have a Raspberry pi 3. I use correctly the driver and display data from the device with cat dev/pcan32
But I would like to know : could I record the data from the device connected with the PCAN-usb?
Thanks,
Best regards,
Camille

if you use the CharDev (Character Device) driver you simply could pipe the output of the console to a text file.

Is it possible to record automatically every received data from the device and using theterminal in the same time?

Yes - use a second terminal instance

If you use the CharDev (Character Device) driver you simply could pipe the output of the console to a text file.
If you use the SocketCAN (NetDev Device) driver you simply could use the Tool candump.
(see SocketCAN documentaion on GitHub)
