PCAN_ERROR_XMTFULL when sending first message

[HPetruck]

Hello,

i get the error PCAN_ERROR_XMTFULL, when sending the first message via the PCAN USB interface. I use the PCAN Basis API on a Xubuntu OS. Before I try to send the first message I have successfully called the methods CAN_Initialize and CAN_FilterMessages. Do you have an idea where my problem is?

Hi,

you are using the netdev driver interface, see can0 in your output. To use the PCANBasic API, you need to build the driver with the chardev interface. Remove the driver again, and build it with the NET=NO option again.

BTW: the Linux section will be a better place for this topic. [Already moved this topic (M.Gerber)]

Thank you for your answer, I will try this.

Unfortunately I still get the same error. The output of cat /proc/pcan is now:

Hi,

please send that output again, after you have used PCANBasic API with your application, to see the read, write and status of the hardware. Sure you have another CAN hardware and a terminated CAN cable connected to the PCAN-USB? Can you send messages with transmittest or echo "m s 0x11 2 0x12 0x13"> /dev/pcan32

That was already the output of after using the API. The methods CAN_Initialize, CAN_FilterMessages and CAN_Write have been called. Yes, I have other hardware and a terminated cable connected. If I call the exact same functions with the same parameters from my Windows program with the PCAN Basis API, everything works fine. The transmitest did run without any error messages. The output of cat /proc/pcan after transmitest is

Hi,

which version of the PCANBasic API for Linux do you use? Can you please test with the examples (c++, Java, Python) we deliver with the API, to see if those applications will work on your system.

regards

Michael

BTW: there are a lot of errors visible in the output.

[HPetruck]

The test program pcanwrite works fine. The API version is 2.0.3.
