I have never used EtherCAT as in doing a full setup, although i have fixed industrial machines using it i never had to mess with the EtherCAT part, so no idea.
I have used and use a lot of Mesa boards, they are worth every cent/penny/dime as they are extremely reliable and come with the best support on planet earth in the shape of PCW (an active member here), so i will not be switching to EtherCAT ever, especially since i learned it lacks some important stuff for me.
BTW, whatever the price for Mesa is, i have to pay at least double to get them here (black hole named Kosovo), still, i pay it gladly.
Reminds me, have to order some THCAD, installed the last one today.

Haben sie ein DVM/voltmeter?
Mesen die 5V wen die karte an ist, was ist die voltage? (spannung < ist das corect geschrieben?)

Nicely done, maestro.
Thank you.

Thank you for your contribution.

Hi guys,

Related to the previous post, where i was struggeling with a node library for too long time.

I had to make a choice what to do.

1. Just don't use the qtnodeeditor lib.
2. Don't use node structure's.
3. Try to create your own lib.

Choosed nr.3.

It took a few day's to figur out how the qt grapics widget works. And how to display qt widget in it.
Then made a solution for creating a simple setup for input, output ports and their widgets.

In the end, the result surprised me.

This is a test video, that loads a few input and output ports, and widgets attached to the port.
Then you can connect the output ports with the input ports. Data flow will stream then from output to input.

This whole idea can be used to format several big and complicated projects, like :

1. rtapi multi threading on several cpu's.
2. super imposed interpreters, running on multiple threads.
3. cnc machine interpreter to machine axis layout. Like connecting ABC, UWV axis.
4. Ethercat bus simulator on real hardware.
5. Plc

User can just create .ui based widgets. This is easy to design. Each .ui widget then may have multiple input or output ports.
The logic is then done by the .ui class, wich conttains also the .h and .cpp files.

Let me know what you think, this is just an example :
