Linuxcnc has a hal driver for ethercat master as it doesn't require any special hardware. Ethercat slaves AFAIK require an ASIC and it's pretty expensive. I hear alot of talk of ethercat but rarely see it actually used in industry. I don't know the status of the hal ethercat driver in MK but if it's not there why can't it be added (meaning what does it have to do with Beaglebone specifically). As for the slave, Not really sure I see why you would use a BB as a slave but it sounds like it's not practical. If this was something I were gonna use I'd be glad to have a smart serial channel or 2 On Wednesday, June 24, 2020 at 6:09:06 PM UTC-4, [email protected] wrote: > > Hi, > Jun 23, 2020, 20:45 by [email protected] <javascript:>: > > > On Thu, Mar 12, 2020 at 7:14 PM justin White <> [email protected] > <javascript:>> > wrote: > > > >>> On Thursday, March 12, 2020 at 6:32:52 PM UTC-4, Chris Albertson > wrote: > >>> > >>>> Isn’t that something the Beagle is strong at with the eQEP and PRUs? > >>>> > >>> > >>> > >>> Strong only until you hit up against the limited number of I/O pins. > A PRU based solution is cheap and simple but can't scale. > >>> > >>> In general TI's idea to place a small microcontroller on the same chip > as their ARM Cortex-A was good and we see others doing this too but a big > machine tool like a 5-axis mill with tool changer and cooling and saftey > interconnects is going to need something bigger than a PRU.
