Marlin: [BUG] SKR Pro v1.1 and TMC 2209 in UART mode compilation error

Created on 13 Jul 2019 · 25Comments · Source: MarlinFirmware/Marlin

Hello,

I am trying to compile Marlin 2.0.x from yesterday for the SKR Pro v1.1 with TMC2209 in UART mode and I am getting some errors:
Screen Shot 2019-07-13 at 9 22 47 PM

also the Software Serial Pins in pins_BIGTREE_SKR_PRO_V1.1.h should be these, got them from SKR Pro facebook page;
67180451_2488543284535986_2141550678961553408_n

any ideas? I can test things if needed, compiling on Ubuntu 18 in Atom/Platformio.
thx

'platformio.ini'

Change TMCStepper@<1.0.0 to https://github.com/Msq001/TMCStepper.git

Zip configuration files and attach to message. Also, note which version of TMCStepper library you use.

I have TMCStepper 0.4.5 in Arduino from github.com/teemuatlut/TMCStepper

Here are the config files:

I think @teemuatlut has to work on it again.

Marlin can be compiled with this library FORK (https://github.com/Msq001/TMCStepper.git).

I couldnt figure it out the single pin way that is currently in the pins file (Tx and Rx are the same pin) so changed to what is above and seems to work. M122 looks good for all of them anyway.
The board is setup for the 2 pin way and those pin numbers are off the btt pin diagram.

Single pin mode depends on support by either hardware port or software library. You cannot just put same ports in config and hope it'll work.

@EvilGremlin The pins file in Marlin currently is setup for single pin. I have never used it and not familiar with it so just changed the pins to what is called for in the pin diagram.
Single pin prob works or I would guess the pins file wouldnt be the way it is, but the board is setup for 2 pin so I gave it a shot that way and it worked.

The latest Marlin does not compile with 2 pins defined either. I'm getting the same error

Good point. I was using the one on btt github and dont remember straying out of the shallow end =D

zillarob on 14 Jul 2019

yes, I tried compiling both single pins or the above configuration but the error persists.

It worked ! compiled successfully !
So it's the TMCStepper library that needs to be an update.
thx for the support !

SoftwareSerial is not supported internally by the STM32Duino framework.

teemuatlut on 14 Jul 2019

@teemuatlut so does it means that the above pin layout is not ok? and the single pin layout is ok?
thx

biskero on 15 Jul 2019

No SW Serial means HW Serial only.

Alternatively you can use the Bigtreetech fork or modify upstream Marlin.

@teemuatlut, I assume SoftwareSerial for STM32 chipsets will be added sometime relatively soon in the official TMCStepper library?

eightheads on 16 Jul 2019

TMCStepper will not be adding any internal Serial implementations. That's firmly in the realm of either the platform framework or a supporting library for the platform.
When that exists I can easily add STM into the supported list.

EDIT: SW Serial library has been added to the STM platform.
