print ECAT frames #763

Closed open04 closed 7 months ago

open04 commented 7 months ago

Is it possible to print the ECAT frames? will use for debugging purposes. I want to print out the frames when I write on SDO or PDO.

Yes, easiest is to use WireShark. It captures all Ethernet traffic, and has special filters for EtherCAT build in.

Hi Arthur, sorry for confusion but what I meant was to print the ECAT frame in the code itself, in Cpp. I want to see the frames Im sending in the terminal, not to use another application.

You can do it yourself too. If your print a hexdump of the outgoing and incoming packets. Or you make a complete parser like WireShark does. Why can't you simply use WireShark? Everyone else does it this way with great satisfaction.

The location you want to plug into are ecx_outframe() and ecx_waitinframe().

Thanks Arthur!, Ill try the ecx_outframe() and ecx_waitinframe().

Im using Wireshark and I can also read frames from there. What I want is to print selected frames on the terminal which makes it easy for me and also my colleague to debug if we encounter problems.

I didnt expect it to be complicated. I will not include it on my package, Ill close this issue now. Thanks again Arthur
