Hi,

is there something special to consider using the PCAN-Chip USB and the PCAN-Chip USB Evaluation Kit?

I use a RaspberryPi CM3 with kernel 4.4.44-v7+ and the driver included in the mainline kernel. Using a PCAN-USB FD (IPEH-004022) with canutils and socketCAN works just fine. However, the PCAN-Chip USB Evaluation Kit is not recognized (e.g. as can0).

Thanks in advance!

Hi,

the PCAN-USB Chip solution is very new, and will be supported by the kernel driver with kernel 4.11 or higher. As a workaround, you can install our peak-linux-driver 8.4-beta, which is available on request (by email, use our support address).

Hi,

i have received and compiled the driver successfully. Now, cansend etc. is working with the PCAN-Chip USB Eval Kit on the Raspberry Pi CM3 as well.

Thank You very much!!!

Hi,

I just set up the PEAK CAN USB and RPI3, now i can read the can signals using candump command and send the signals using cansend command. Anybody knows how to send/read through python program, i understood that these commands are not available in python.

Hi,

if you want to use the SocketCAN driver, ask the SocketCAN maintainers for python support.

When using our peak-linux-driver with chardev interface, you can use the PCANBasic API. With that API you will also get python examples.

Hi,

Thanks for your reply. I have already installed the PCANBasic API and ran the test program also.
I want to send the can signal as well as read the specific can message from python program. I was using "PCANBasic.object.Write()" function, but failed to get the output.

Hi,

please post output of cat /proc/pcan to see that you use the chardev driver interface

Hi Michael,

Please find below the output.

Right now i am able to send the CAN messages through Write function in python. Now i want to read the specific can messages then need to copy the data into one variable using python. Any idea?

Thanks in advance.

Hi,

you have build a netdev driver , to use the PCANBasic API you have to build a chardev driver.
