And the fact that its not sharable, was why I used the SPI interface to run the sheldon lathe with an rpi, 3b at first, now a 4b. Most of my machines run thru a simulated parport in the form of a Mesa 5i25 + daughter cards, and I don't know how fast that is, Peter s/b able to address that, but the SPI, driven by the pi's gpio's, is amazingly fast, sending data in 32 bit packets to the mesa 7i90 card at 41 megabaud, and getting replies back fron the mesa card at 25 megabaud, If thats not realtime enough I don't know what is. That does require treating the interconnect cable, in my case an inch long, as the transmission line it is. So my rpi still has a normal net connected to it, and ATM has two shells logged into it from this machine. I can fire up firefox and tour the planet, on the pi. > I would expect to connect an ethernet board directly - and not share > the network. > So that should help. > cheers, > Torsten > > _______________________________________________ > Emc-developers mailing list > Emc-developers@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-developers > .
