Has anyone programmed a library to handle CANopen devices on a simple CAN interface? E.g. the X20CS2770 doesn’t have CANopen, and handling multi part sdo reads etc. manually is very inconvenient. But since everything is described in the CANopen spec, it should be possible to have a little wrapper lib to make life easier?! Anyone has something like it? Would be highly appreciated (and save me some work…)!
i will send you a Lib.
Hi @stephan.herbig, would it be possible to share the library here?

Hi,
I am testing this library between two X20CS1070 cards but can’t make it work.
Can this library be used only for master-slave communication type or can also be used for direct data exchange between nodes?
Hello Andrius,
this library represents a CanOpen Master. In order to be able to establish communication between two X20CS1070 via CanOpen, a CanOpen slave is required on the second controller. This library does not offer this function.

hello,
Did you try to use the CAN_lib library?

Hello Stephan,
Can we use above library CoMaDevice for preconfigured Salve Device by keeping enable input pSlave.Device.enable => FALSE, So that We can use Only PDO Read & write communication without Activating SDO, As we have preconfigured Slave Device
works great
thank you Stephan
Hello,
you can simply delete the data object from the software configuration. Then the slave starts with its preset values.

Stephan
Thank you for your feedback

Hello Sven,
yes i use can_lib!
