I didn't realize that, looking into it it seems there is some ethercat slave support on the BBAI though what I've found seems a bit inconsistent as to whether it's fully useable. > This seems like an asymmetry to me. You say that nobody use Ethercat based > systems,...... I didn't say "nobody" uses ethercat, I said I rarely see it in industry. First because it's fairly new, second because of it's cost to implement and common serial protocols and TCP pretty much cover basic needs. High end stuff like the Rexroth Indradrives and MLCs are the type of thing that will actually get deployed as a system but then again they were always on some late great protocol like Sercos and "fast ethernet" ....but then want a support for solution that really nobody use and is not > that good in first place. The community that MK tries so hard to separate itself from uses it quite a bit, and I'd disagree about it not being good, it's good at what it does and the cost of implementing is nothing, 2 gpio pins that'll run at 2.5mhz and $0.10 worth of components. And for a very low cost it can easily be the basis of solving the concerns about not having enough GPIO. An MCU on a daughtercard can easily run SS slave firmware and it's a route for expansion that doesn't cost this board much of anything. > Why not use something which is developed and backed by a quite big group > instead of one-man-show? > HM2 is open source, it can be an any number man show. Funny that an MK dev would toss that out when MK was the first to fully port it in the fantastic-yet-undersupported-mksocfpga. HM2 made that possible and SS works there, yet not so great in MK itself. Is Multinode well developed in MK and in much use currently? -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
