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

Category: Computers and Hardware

I haven't had a chance to really give it a good go lately, other things have got in the way.
But I've found your project to be solid and though it doesn't really relate to your project, but when I came across it I was in a bit of a dark place and it gave me the will and drive to get active again.

Here are the general signals that was generated for me by pncconf some years ago.
net spindle-vel-cmd-rps        <=  spindle.0.speed-out-rps
net spindle-vel-cmd-rps-abs    <=  spindle.0.speed-out-rps-abs
net spindle-vel-cmd-rpm        <=  spindle.0.speed-out
net spindle-vel-cmd-rpm-abs    <=  spindle.0.speed-out-abs
net spindle-enable             <=  spindle.0.on
net spindle-cw                 <=  spindle.0.forward
net spindle-ccw                <=  spindle.0.reverse
net spindle-brake              <=  spindle.0.brake
net spindle-revs               =>  spindle.0.revs
 net spindle-at-speed           =>  spindle.0.at-speed
setp spindle.0.at-speed 1
net spindle-vel-fb-rps         =>  spindle.0.speed-in
net spindle-index-enable      <=>  spindle.0.index-enable
net spindle-revs              <=   hm2_7i76e.0.encoder.04.position
net spindle-vel-fb-rps        <=   hm2_7i76e.0.encoder.04.velocity
net spindle-index-enable      <=>  hm2_7i76e.0.encoder.04.index-enable
net spindle-manual-cw     halui.spindle.0.forward
net spindle-manual-ccw    halui.spindle.0.reverse
net spindle-manual-stop   halui.spindle.0.stop
You would need at least the enable and one of the vel-cmds.
Maybe forward/reverse and so on.
They all connect to the spindle pins (created by the motmod component).
Speed feedback is optional but nice to have, at-speed if your spindle can do that.

I'm civil/builder/construction labourer, using the page I linked to I was able to create Mesa bitfiles (then some custom ones for a clone board I made).

What it comes down to is being able to follow instructions.

A small request to everyone who uses Rio.

I hate telemetry in software, I don't want it in other software and I don't build it into mine either!

The downside, however, is that I never know if the stuff is any use at all.

I'm always happy when someone writes here that they've built a custom board, or when I happen to see pictures or videos online of boards I don't know yet.

An open source programmer usually only sees the problems and errors that users have, but very rarely reports of success.

So I would be very happy if you could give me a little feedback.

And even those who don't use it can say what they think is missing or what is stopping them from trying it out.

Best regards, Olli

@Dave3891, but you can send me the files (pinouts + board-image),
than i can create one for you

Thanks !

not really, in 'riocore/files/pin*.py' are some helper scripts for me (dev-branch),
but yes, most i do by hand.

@all
---- WARNING --- parts of the dev-branch is not usable at this time,
i do some bigger changes for the joint/axis configuration

20 years ago I tried Linux CNC once, but I gave up due to language barriers and the European purchase restrictions of the cards.
I have built quite a few CNC machines in the past 40 years in systems running under Win.
Today's language translation programs can be an incredible help.
Clone cards are now available at a reasonable price, so I thought I would try the Linux world again.
The helpfulness that the Linux forum provides is amazing.
A special shout out to PCW for his help and expertise that he shares.
I am an electrical engineer and I can create an electrical circuit diagram in minutes. My limitations when it comes to PC programming are huge. I have been trying Linux for 2 weeks. I still have a lot of questions. Today I will upload the unique configuration I received from PCW to the 7I92 card.

  Hello everyone. Can anyone tell me why the set coil works like a regular relay, and does not remain on when the input signal disappears?
I tried sending %B0 to the internal relay. The result is the same.

Should add that the frequency seems to be a percent x 100. so setting it to 100 gives me 13.33 hz which is 1% of full speed.

Gonna need to work that into my math. :)

Greetings,

I have a 6i25. The manual for the 6i25 states "These is a small speed advantage and some additional 6I25 features available if the card is runs as a native 6I25. To do this, a 6I25 bitfile must be loaded in the 6I25's EEPROM, and the local PCI clock set to 66MHz."

I have toggled the jumpers to set the PCI clock to 66MHz as per the manual. I cannot find the 6i25 bitfiles in the www.mesanet.com/software/parallel/5i25.zip archive.

I have reached out to mesa requesting support, but they have not replied as of now.

Has anyone successfully loaded a 6i25 bitfile into the 6i25's EEPROM? If so, where did you get the 6i25 bit file?

Regards,

John

aha!
looked at that add in card and realised something. it is an int with multiple settings (start, reverse stop, etc). but when the pin initialises it writes a 0, which is not allowed.

so i ignore that and in halshow make it 1 and it turns on. and 6 turns it off.
So now that all makes sense!

The next thing i see is frequency is not 2001, its 1000 (4096 in decimal).

So a quick test of that and we get... motion!

(except its going reverse which is a setting i can change)

woooohooooo

so now, we need a hal and then a spindle section in the ini? because i am using ethercat from scratch here, i have literally no other functions in my main HAL or INI.

What should i be expecting to add there?

Thanks!
