Chat GPT is uesless for more things Linuxcnc related.

Googling "linuxcnc 7i92 g540" (the TF denotes a different fpga but it functions the same)gets me this (possibly the most in depth one, I dont think too much has changed in pncconf since 2023):
forum.linuxcnc.org/49-basic-configuratio...and-g540-combination

This one has some simple hal files to look at:
forum.linuxcnc.org/49-basic-configuratio...indle-encoder-issues

forum.linuxcnc.org/39-pncconf/29692-can-...re-mesa-7i92?start=0

Some of them are a little old, hopefully PCW will chime in with some up to date info.
I think the first link has some screenshots of PncConf.
