Post by elpimous12 » Sun 26. Sep 2021, 11:16

Hello the team.
Do you have an example, to call the command "can send" on peak board on c++?
anything like this command : can send 800a 140501 ..

Thanks the team.

Hi,

which PEAK hardware do you use (serial number)? Please post the output of "cat /proc/pcan", "uname -a" and "ip a"

regards

Michael

Hi,

when using a kernel version 5.x and you want to use the SocketCAN tools (cansend, candump etc.) please uninstall the peak-linux driver and reboot once, so that the card can be used by the kernel internal NetDev driver:

- goto the peak-linux-driver-8.12 directory and call: sudo make uninstall
- sudo reboot
- check with ip a that there are can0 to can3 netdevices available
- install the can-utils with apt
- configure the canx devices to your needs with sudo ip link set ........(see SocketCAN documentation for more details: https://www.kernel.org/doc/Documentatio ... ng/can.txt)
- see the help of the can-utils applications for more details how to use them, or how to write own applications for SocketCAN.

regards

Michael
