My current spindle is very low tech, a bosch colt. I would use a 4-20ma
amp donut, perhaps wind a couple extra loops.
I'll have to think this over a bit. It is one thing to write a driver when
you have complete docs, yet another when you have to search so many places
for all the information.

Well, the docs do exist, but don't seem to be linked to
seems like only things that start with hal_ or rtapi_ get built and
added to the html from that directory. I assume it is a submakefile
thing. None of the man pages are directly included in the PDF docs.

I have also been mulling over the ft232h. I asked ftdi, but never received
a reply, about the latency. I assume it is at least 125 usec, but that
depends how that everything is managed. If the usb host stack could be
hacked to give extra care to a specific device, it seems it could work,
I have the master, as of a couple weeks ago, but I don't see any of the hm2

You just want an overcurrent limit, or you want an analog measurement

I don't care about an analog measurement, I want the system to pause or
park when amps are outside of a set range. How would you do the first
scenario?

I also am not very clear on emc2 capability to manage analog inputs, it

The mesa card looks interesting to me. The catch is, how is one going to
go about doing spi and pulling the data into emc2? I assume everything
would have to be bit banged, and is not taken care of in the fpga. It also
says it has quadrature encoder interface, but once again, how is this

Does your spindle drive provide an overcurrent signal? If it is a
contact that opens on
fault, you can just wire it

It all depends on the RPM. 1000 count/rev encoders would be fine with
