Remora - Rpi Software Stepping Using External Microcontroller via SPI

anyone looking to use the new thing with RPi5, keep in mind, you need to use the new firmware also. Right now Ive added a precompiled firmware for octopus446 and more will be added later but you can compile your own in the meantime

Yes, good point cakeslob. The new component includes the spike filter and relies on the raw count feedback from the controller board, not the DDS accumulator value. A good opportunity to migrate to OS6 firmwares and legacy the OS5 versions.

fuck i dropped my octopus and broke the sdcard on my way to testing bench.

but our first catch of the day -
Nucleo f446 doesnt want to reconnect to RPi5. after the first time i connect to linuxcnc, the nucleo doesnt reconnect unless i reset the board. otherwise i get bad spi data, will investigate further.
doesnt happen on rpi4
my little STM32F411 board works great every time for some reason


edit, tested with my second favorite octopus, and everything seems fine, i will chalk this one up to jankly nucleo

i like how fast this rpi5 is

Does it support BTT SKR PRO V1.2?Should I edit the source code and recompile the firmware for it or just use  BTT_407?BTT SKR PRO V1.2's MCU is STM32F407ZGT6 teamgloomy.github.io/skr_pro_1.2_pins_3_5.html

---

I tried to add BTT SKR PRO V1.2 to the custom_targets.json, mbed_app.json and edit main.cpp.After compiling it, I got the fiemware.bin.I wll test it when my RPI is delivered.

 

Greetings,
I have two nvem cards, I can't read all 80 pages of the post related to the implementation on linuxcnc, can you explain step by step the procedures of a short way to implement them on linuxcnc, in the shortest possible terms for those of us who have very little knowledge about programming. thank you
   

Best to start with
www.forum.linuxcnc.org/18-computer/44828...c300-ec500-cnc-board

The board you have is an STM based board, which was the first Ethernet board to be supported. So the early part of the above thread covers the development and firmware installation stuff.
