I used in CAN network and have seen something about it is available on
Ethernet. To send messages over SPI or UART should be no problem. Nice thing is
PDO for real time and SDO for configuration, then i use interpolated position
mode there is a need to set the gain.

For permanent magnet motors there is a rather linear correlation between RPM
and voltage although field weakening might be possible to lower voltage then

I got a simple Ethercat board with a LAN9252 chip and SPI interface.
The chip seems to work although SOEM and eepromtool seems to work but then
checking it seems eeprom never i programmed. Anybody else who used eepromtool?

Have anybody tried Etherlab master on a recent kernel lately?
Howto to get driver available in source into linuxcnc?
Soem work fine and process data seems to be both received and sent so this
might be another starting point.
Regards Nicklas Karlsson
done quite early but this is
by now rather old software.
I guess these kind of changes may be included in current RT patch. The question
is if a standard RT kernel as is today need changes to the drivers to get good
real time performance? Any idea?
Regards Nickla
If I want to add new driver to linuxcnc, any idea howto add sources into build
