hi fiends. i'm new on ros and i need to understand how to interact with the lwa4p. somebody can help me?? but i have the "KVASER LEAF ligth 2

i tryed the following: i installed the linuxcan diver for kvaser manually and i changed the name

can0 for leaf0 in the can0.yaml file

then i tryed to run robot.launch and doesnt work :

velarje1@cemie-p02:~/schunk_ws$ rosservice call /arm/driver/init success: data: False error_message: data: CAN init failed

my question is ... do i need to change anything else? or i need to use the peak only for this application? thank you very much

You need to uninstall the Kvaser drivers in order to use the SocketCAN. SocketCAN gets blacklisted by installing the LinuxCAN.

You may want to take a look at https://answers.ros.org/question/3085...

where I have already explained that.

It might be a little bit too late, but you can find more information on the CAN implementation here: http://wiki.ros.org/socketcan_interface

The current implementation just wraps the SocketCAN net interface (not to be confused with the actual device, maybe we should rename the parameter name). I have tested PEAK and ESD only and both came up as can0, can1 etc.

However, KVASER should be supported since kernel 3.8: http://www.kvaser.com/faq/linux-can-u... If the can-utils work, then ros_canopen should work as well.

I have a Kvaser CAN USB and it shows up as can0 on my system.
