LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

Great insights, thanks for that! That's why it's paramount importance to get the actual physical ISO776x part on the benchtop and oscope each and every single pins' state when powering-up -and- at runtime (MPG, Omron Encoder, Stepper Drive, INs, and OUTs). Only way to confirm!! Pulls HIGH, translates and isolate as advertised!! 3-in-1, highly recommend. Mind you, there is also a pulldown ISO776x variant - if resistors are preferred (ISO7760FDBQR). 

LinuxCNC-RIO 5AX Motion Control Board (9k, 10ins, 5outs, wired mpg, 100mbps, jtag, lightning proof lol). Going out to the pcb fab tomorrow. Should get this back in 5~7 days ready for assembly. Hard work... 

WOW, looks very nice 

It's tiny (90mmx70mm). But big enough to get me started with RIO. Sure packs a great punch!!

Making 5 (five). Four for myself, and one for you You'll need to think of a way to let me know how to get one of those to you in DE.

If possible, could I have a 5AX please, obviously I'd pay for it?

+13 years linuxcnc.org member. My God, you've been around and respectfully deserve one of those 5ax more than I do. I'll arrange that for you, np.
More or less fifty bucks worth of parts + a $15 jtag programmer. Ball park. Let me know if you're still in. 

Rgs.  

Do you think it could also work with a USB blaster?

Thanks, I'm in, it looks fantastic, great work, I should say that I'm an IT guy tinkerer nowhere near as talented as most of the folks on here but LinuxCNC is the only system I've ever used. I love Linux. The HAL still gives me heart palpitations.

I wouldn't know for sure, Oliver. Nice thing about Gowin's is the endless jtag probes avail, for all I know. I have 3 here that works perfectly fine (up to 10~15mhz). The one you saw in previous visuals (FT232 based), and the ones below. All <$15. 

do they work under linux ?
and with which software ?

Yeah they all do linux. Software: Gowin_V1.9.10_linux (/programmer/driver folder).
$ sudo Gowin_USB_Cable_Installer.sh
$ sudo make
$ sudo chmod -R 777 /etc/modprobe.d/

Done.
