Trouble with PCAN-BASIC

[lammer18]

Hello, I am working with a PEAK PCAN-PCIe FD on Linux and having trouble with both the PCAN-Basic tests and the peak driver test. Heres my method and outputs from a few commands

For Drivers:
sudo rmmod pcan
make clean
make NET=NO
sudo make install
sudo modprobe pcan

Output from

When I run PCAN-BASIC c++ example

Code: Select all

$ ./pcanread 

Code: Select all

Initialize CAN: 512
Error 0x4000000

I assume this

PCAN_ERROR_INITIALIZE 0x4000000U

error comes from the fact there is no CAN0 bus initialized on the device. I do not know what to do at this point. I have used PCAN Windows API to successfully send and receive expected results.

Thanks!

So after still not having luck I worked on using the pcanfdtst and still no luck. I added a memcpy call on line 1105 of pcanfdtst.c to send the fields I want.

Case in point: I have PCAN API working on Windows both sending and receiving as expected and cannot get the same functionality in linux

Is there anyone that provide assistance?

Hi,

Can you give us the exact command line you used with pcanfdtst please?

FYI, if you want to display the CAN traffic from read from /dev/pcanpcifd0 connected to a CAN bus set to 1Mbps bitrate, you should run:

Code: Select all

$ pcanfdtst rx -b 1M /dev/pcanpcifd0

Can you give us the result of the above command?

When the above command runs, can you open a 2nd shell window and type "$ cat /proc/pcan"
Do you use the same PC/CAN bus with Windows too?

Regards,

Stéphane

Stephane,

The command I use with pcanfdtst is:

Code: Select all

pcanfdtst tx -b 1M -i 0x0c4 -n 10 -l 2 /dev/pcanpcifd0

also to have similar settings to the windows implementation:

Code: Select all

pcanfdtst tx -c 24M -b 1M -d 2M -i 0x0c4 -n 10 -l 2 /dev/pcanpcifd0

Result of

Code: Select all

$ pcanfdtst rx -b 1M /dev/pcanpcifd0

is blank and doesn’t display any received frames.
2nd terminal runs cat /proc/pcan and gets:

The hardware is the exact same for both windows and linux implementations.

Thanks,

Hello Kyle,

You have successfully written 10 frames on CAN0 (as said by the "write" column of cat /proc/pcan, in hexadecimal).

But you won't be able to "read" them from the SAME channel. You have to connect CAN0 of the board to (for example) CAN1 and type:

Code: Select all

$ pcanfdtst rx -b 1M /dev/pcanpcifd1

To have any chance to read them.

Regards,

Stéphane
