Remora for RP2040

I am also having this issue. The controller hangs when i use outputs.
Any luck finding a solution?

Hello,
I have no idea if it is the right place to ask, but I have a question regarding remora.
Is it possible to drive a Spindle with a step/dir interface in remora? 
Thanks
 

"I'll need to update the firmware with the absolute position feedback and spike filter like we've done in the NVEM / EC300 / EC500 firmware and in the dev version of the original Remora. Solves those following error spikes. "


Hallo Scotta, did you have it time to update the firmware?
Thanks!

Hi, I have been looking at this and cannot replicate the issue. Please share your config file as all the combinations I have tried work ok for me.

Ok, some more investigation. Using the publish uf2 file and your config I confirm the issue. I've recompiled my master branch which had some unpublished clean-ups (debug info) from the ping-pong buffer implementation, and your config happily loads and runs.

I've also added a firmware folder to the repo to make finding the uf2 file easier.

github.com/scottalford75/Remora-RP2040-W...ora-rp2040-1.0.1.uf2

I'm working on making the RP2040 version compatible with the latest LinuxCNC Remora ethernet component, but currently this version still uses the legacy remora-nv component.

I've migrated the Remora for RP2040 to now use the Remora-eth-3.0 component. 

Download the latest firmware

github.com/scottalford75/Remora-RP2040-W5500/tree/main/firmware

Upload the remora-rp2040-2.0.0.uf2 file to your pico.

To configure the linuxcnc hal module and configs use the files here:

Hal Files (run halcompile on these)
github.com/scottalford75/Remora-RT1052-c...omponents/Remora-eth

and the configs:
github.com/scottalford75/Remora-RP2040-W...onfigs/remora-rp2040

Is it possible to work with rp2040 via uart instead of Ethernet? Is the bandwidth and response time enough? I'm considering a variant of sbc on Intel n100 with rp2040.

No, even at high baud rates, serial is just not fast enough.

Now we need them to combine the newer 2350 with the W5500.
