Remora - Rpi Software Stepping Using External Microcontroller via SPI

When you say already supported is there a Hal and conf already made out there with a pinout. i would love to try this

Hi, the Hal config for Remora does not change significantly from board to board as it is mapping the LinuxCNC pins to the data packet that is sent to the controller board. 

The config file for the controller board is where the physical pin mapping is done, translating the data packet info to the modules and pins. The BLACK_F407VE is totally open for your definition.

So to configure it for my use case i would need to compile the code myself?
I am using a skr pro 1.2

To make it work for multiple boards would it be possible to load 2 different QEI depending on the board set in the config?

Hi, I'll need to look a the 407ZGT to see what encoder pins are available on the extra ports the chip has. It does not look like the pins I listed earlier are available on this board either.

From a config perspective, if there is encoder pins exposed it would be possible to update the config parameters for the QEI module to include the pin definition. From there the correct timer could be selected and configured.

BTW, it looks like a really nice board. The software encoder module would be your fall back, you can use any available pin with that module.

any one tested the software encoder on these stm32 boards to find the max input before it starts to drop pulses.

I've tested the STM32F407 with a base thread of 80khz, the base thread frequency will be the limiting factor.

I'm putting in more work to get Ethernet connectivity up and running. Found this project which is pretty active on the RU CNC club forum.

It might be a good start for Remora-Net capable BoB...
