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

There is now support for a Mesa board: eusurplus.com/index.php?route=product/product&product_id=131
It can be used via RPI over SPI and over Ethernet via W5500



There are also developments in the new configuration front end, but it is still far from complete.

PS: Many thanks to EUSurplus for their support!

Best regards, Olli

I am getting this right, the W5500 acts as an Ethernet bridge ?

So this should also work with the 7I90HD in spi mode ?

Or any Mesa SPI firmware (custom) like something I've put together ?

Yes

7I90HD should work with small changes

No,
This has nothing to do with the Mesa gateware/firmware; RIO runs on Mesa hardware here.
Mesa gateware does not support W5500 modules.

So basically you're supporting Mesa hardware, something I mentioned along time ago, which the Spartan6 hardware I added to the repo basically is, 7c81 ish clone.

Exactly, and now I also have an original mesa board with which I was able to create a board file and test the whole thing.

OK, there only dif in mine clone was the SPI & FPGA clk pins. Seemed to be very picky regarding that.

Any code in the repo yet ?

Can't believe I missed it.

I am successful and fully transition from my old Parallel Port PC to an I7 Laptop with Riocore! Finally I am able to browse something without waiting forever Thanks Olli! This is great stuff.

I have my
- whb04b-06 Hand wheel operating
- Classic Ladder with RS 485 Modbus working (over an dedicated RS485 USB Dongle)
- Auto squaring Y Axis
- Touch plate/Probe input

It was not terrible, but I feel like I have modified a lot of ini and hal files which were created automatically to make this work. Is there a way that you could add a checkbox or so to ricocore gui to not overwrite the existing config files?

I don't know what the best workflow would be. I think if I want to add another function to the FPGA i I will just do it in a separate folder and flash the FPGA, then add the changed manually to my machine folder ?!?

@mBender

You can simply copy the directory and use it, then enter the updates. It's the same as a ‘do not overwrite’ switch.

If you send me your configuration and your edited files, I can see if there is a way to integrate this into the json-configuration.
