Hi,
The ethercat auto configurator works finally !!
When program starts, it initializes the ethercat devices by retrieving a digital xml configuration.
For this i poked around in the etherlab source code, and added some function's to retrieve this digital xml information.
From the given digital xml information, it then does some logic and it create's hal pins automaticly.
This is ideal for lazy system integrators. image missing /media/kunena/emoticons/smile.png
For this to use you don't need a .xml config file like in linuxcnc-ethercat.
I also solved a etherlab_master software
bug
related to slave alias numbers, wich where not consistent and
resulted in head scratching for some time as the aliases are not printed by : "$ ethercat xml"
The terminal output when starting the program :
Code:
Starting EtherCAT master 1.5.2 done
init example 0.
init ethercat start.
Print ethercat devices and retrieve device data vector.
No alias given, alias -

PDO entry registration ok.
Master ok.
domain1_pd ok.
init ethercat succes.
So far 4 data types are integrated : bool, uint, string, bit.
It currently looks at one master. But code may look at more masters in the future.
So far so good !
Integration in linuxcnc is not that difficult, as you can add this code into a component, using a function like
rtapi_app_main(); will then run the code, will also create hal pin's etc. with some slightly modifications.
