STM32F407 support?

[towe96]

Biqu has just released the SKR Pro: https://www.aliexpress.com/item/33042699158.html

It appears to be very potent board, with expansive expandability, 6 stepper sockets, and an STM32F407 MCU. I think it's fair to say it's the single best board ever released as of this date.

Is support for the SKR Pro's MCU planned?

Hi @Spacemarine2018, I am having some issue getting my Skr pro with tmc5160s working. Currently my steppers only move in one direction and my steppers are wired AABB. Could you post your config so i could compare it to mine?

Here you go @Nelanius printer.cfg.txt I don't have the sensorless homing working, I just connected the physical switches, so the config looks misleading in that section.

Can anybody with a working TMC5160 V1.2 from BTT and an SKR Pro post the printer.cfg? I'm having the problem that I can write via SPI, but not read and I want to make sure that it's not a configuation error.

Also please check if you get meaningful values (not only 00000 or fffff) when doing DUMP_TMC STEPPER=stepper_x just to make sure you can actually read and not only write SPI.

Only for 2130, should be similar i guess, do you need it?

@Spacemarine2018. Why not run them in UART mode? I ran my 2209s in UART mode. I'm pretty sure the technical bits on the 5160s are good ng to be the same. Only. Small thing that's incorrect on the specs for config. TX and RX are on the same pin... So in klipper you need to delete or comment out the TX pin line in the driver. Onfig sections

@MrKekson does it differ from the config example here? https://github.com/KevinOConnor/klipper/blob/master/config/generic-bigtreetech-skr-pro.cfg If it's basically the same, I don't need it, but thanks!

@tiaanv interesting idea, I never thought of using UART because everyone seems to use SPI. Any benefit/drawback since the TMC5160 supports both?

You are right, this file was not available when i've configured my machine, but that should be ok too!

I'm going to close this issue as I think the original issue (stm32f4 support) is now complete.
