Hard to tell, this was a few years ago and using a kernel of
unknown
quality.
As in, it didn't work well when I tried it with a software stepgen
at
Wichita, but there were many other possible explanations for the
issues.
Anyone tried it with the new RPi-3's?
Well, SPI is now working and it seems to be satisfactory. I created
an
experimental EPP driver for the 7i90/7i43 (which is why I started
this
thread) but it needs to be tested and I am looking for volunteers.
What all would be evolved with testing? We found a use at work to use
an RPi-3 for a proof of concept, so I will be jumping back into RPi's
for the next while. It would be nice to make sure that the hard
real-time and other systems are running correctly, as well as LCNC. I
also need to get back to some LCNC projects whenever I can break away
the time... Anyway, I or my intern might take a poke at the testing if
it does not envolve to much, or if we can find a way to make it work
related...
