The V to F way seems the best if you can count pulses, it offers better noise immunity. But if you are already making a EtherCAT slave you could just use an optoisolator and an analog input an just read the register. I like to prototype stuff but I don't have a machine to use it on image missing /media/kunena/emoticons/laughing.png.
Today I was toying around with my slave. I made the XML file and installed lcec by your (rodw) instruction
Everytginh is ok ( LinuxCNC side), but I just can't get this darn thing to communicate.
LinuxCNC show that slave is responding (lcec.0.all-op is ok) but lcec.0.0.slave-online and slave-state-init or or or anything for that matter is FALSE
Here are my files
what does ethercat slaves say before opening linuxcnc and while its running? Please share
What happens if you click through the axis buttons to turn it on? what does it say then?
I wanted to make a generic ethercat slave pcb back in -21 but got frustrated because of the component shortage and didn't have the time to finish it. My idea was to create a "base board" with LAN9252 and RPi2040 (pico) that you could attach different boards to it.
If someone wants to continue this, I can share the kicad files, its pretty much done but could be made a tad simpler by removing some extra power components etc. I think this is much more hobbyist friendly as caps etc are 0603 size, uses a cheap pico etc.
