Remora for RP2040

I figured out why uploading the config file didn't work. when giving pins their names in config.txt you have to use GP01 and not GP1. (starting with a 0 for single digit numbers) Very confusing since when looking at pinouts online it is never shown like that.

I'm happy I've got it working now though.

If anyone else finds themselves with this issue, the solution is the first wipe the memory of the pico by uploading flash_nuke.uf2 and waiting for the flash drive of pico to show back up again, then uploading the fresh remora firmware. Then making sure you don't use GP1 pin definitions and always use two numbers after "GP" 

As I understand, with the current implementation, Remora for RP2040 requires W5500 for UDP communication over Ethernet. Were there any attempts to implement direct SPI communication between RPi and RP2040? I couldn't find any, so I opened an issue on GitHub .

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.
