I will use this driver as a starting point since I did not work with linuxcnc before and later on I will probably switch to a standard protocol. I have worked with CANopen and guess the aproach used for PDO communication but sent via UDP would be good but some drawbacks could be accepted if it is a standard protocol. The hostmot FPGA cards seems really good but I think there may be cases then MCU is a better approach but time will tell.
It is probably a few months away but any suggestions for a standard protocol would be appreciated? Nicklas Karlsson On Sun, 14 Sep 2014 15:33:01 -0700 (PDT) "Peter C.
