Marlin: [FR] BigTreeTech SKR Pro v1.1

[boubouexpress]

hello

request to add the BIGTREETECH SKR PRO V1.1
ARM cortex M4 32 bit
STM32F407ZGT6 MCU

https://github.com/bigtreetech/BIGTREETECH-SKR-PRO-V1.1

merci

[govido]

I guess Bigtreetech will submit the changes needed as they advertise marlin 2.0 compatibility.
Yesterday the new E3 mini got merged from them, so I am looking forward to it.

[AnHardt]

they advertise marlin 2.0 compatibility.

That doesn't mean anything to me. Doesn't the word advertisement say all you need to know?
I remember a well know Kickstarter announcing a new Marlin compatible probe.
No other single hardware item caused that deep changes in Marlins structure to make that "compatible" crap finally work. And worst - they continue to change their product, without a warning, to make it incompatible again.

Bigtreetechs history gives me some more hope.
Let's hope for the best.

It is ready

It is ready

Except they do not compile currently

There’s an SKR Plus pins file in there too.

Wonder when BigTreeTech will announce that board.

[thisiskeithb]

See https://github.com/MarlinFirmware/Marlin/pull/14510, but it still doesn’t compile.

14510 this PR was closed because of a conflict files. I will creat a new PR for this board， and https://github.com/bigtreetech/BIGTREETECH-SKR-PRO-V1.1/tree/master/firmware this branch is work now， and Pay attention to the Readme.md

[govido]

As this board is completely new I didn't want to open a new issue directly.
The things I noticed so far (my board arrived yesterday):

• TMC2208 / 2209 are not working because software uart isn't supported yet
• graphic lcd software spi isn't working (tested with fysetc mini 2.1)
• Neopixel is not supported, the library is ignored in platformIO config for this board
• emergency parser not implemented
• lots of pin definitions are missing in the pins file (LCDs, filament runot etc.)
• auto_fan_pin does not compile
• i2c oled display is working for now
• can configure software spi for tmc2130 (not tested yet)
• no option for internal sd card on stm32? or I overlooked an option...
• serial port 0 not working
• bltouch / servo not working

not marlin related:

• the esp 01s port is not working over usb power (not enough current?), module works when powered seperately

If I should test something let me know.
I have tmc2130, tmc2209 to play with, tft35, fysetc mini v2.1, bltouch

1. this PR will support TMC2208/2209 uart mode
2. I have tested REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER(LCD12864) and REPRAP_DISCOUNT_SMART_CONTROLLER(LCD2004), They all work properly.
3. stm32 have not Serial port 0, it begin from Serial port 1
4. I have tested bltouch in PA1 pins， it‘s ok.

I'll test your feedback one by one. Thank you very much!

@Msq001
Nice,
I will take a look again at the terminal output while compiling. I got errors regarding display and bltouch, or they are coming from somewhere else...
If stm32 has no serial 0 there should be a comment added in configuration.h ;)

[govido]

@Msq001
I tested the bltouch and fysetc options again.
I must have done something wrong in my first attempt, bltouch has no errors.
But the display throws this error right at the final compile stage...

With the new new version over at https://github.com/bigtreetech/BIGTREETECH-SKR-PRO-V1.1 they seem to got the tmc2208/2209 over uart working, at least it does compile. My RepRap display stopped working though so there is probably more to do.

Please update the Neopixel library because Fysetc MINI12864 useless without it.

[yellobello]

Is it currently a better idea to use bigtreetech´s sources for the SKR Pro or use the current Marlin 2.0.x-bugfix Branch? maybe dev-2.1.x?
i.e. have the sources from Bigtreetech been merged already?

Please update the Neopixel library because Fysetc MINI12864 useless without it.

That project is at https://github.com/adafruit/Adafruit_NeoPixel

They periodically push updates here.

Hello
you could send your files because I have the same configuration and I can not compile and I can not find the problem;
thank you

[LinoBarreca]

@boelle close this. it's already done.

[boelle]

done and thanks for the headsup

[boelle]

witch such a big list one man is almost not enough :-)
