I don't understand how the last sentences could be compatible with GPL?
lhH EtherCat https://etherlab.org/en/ethercat/ I think is licensend
under GPLv2 license. Master is implemented as kernel module and
drivers are included in source code. Guess it should not be to hard to
re implement to run as a real time thread and rename to Freecat.
in lgH there is some local changes to the original drivers I guess
come kernel, not sure why. I had some problem SOEM with more than
three Ethercat devices, message never arrived back in the ring, adding
a router and it did, not sure if might have something to do with this.
Guess it is against answer myself. Anyway I found.
Checking again it is possible to turn off building of Kernel modules in
lgH so guess it should be rather simple to get into Linuxcnc. Normally
an .esi file if I remember postfix correct is used then configuring file
and ideally it should be possible to configure by using these files and
add .hal pins. Bought Chinese IO modules, 16 bits in and 16 bits but for
these are I more or less hardcoded position in Ethercat datagram.
