Trinamic TMC2240

[thinkyhead]

Add support for Trinamic TMC2240 stepper drivers. Assuming they have the same capabilities as TMC2209 based on the changes in drivers.h and elsewhere.

• Based on https://github.com/bigtreetech/Marlin/tree/tmc2240
• TMCStepper additions based on https://github.com/z1996xm/TMC2240-Lib
• Also requires Add TMC2240 teemuatlut/TMCStepper#270 which should be merged pretty soon.

Will these be configured via UART under Marlin? They’re setup as SPI drivers under Klipper, but I don’t have a set to test with.

Edit: Alan over at BTT just responded to me and said these are setup/configured via SPI as the factory default.

I've finally got a set of these drivers in so I can test them out when code is ready.

Have you by any chance tried what @thinkyhead posted here teemuatlut/TMCStepper#270 (comment)?

I am not quite sure what exactly I am doing wrong, as I can't get it to complie. 🤷🏻‍♂️

No. There's still more work that needs to be done before I test things out.

@thinkyhead
Good morning Sir,
do you still plan to add support for the TMC2240?
Please don't get me wrong, just asking, no intention to be rude.
Hope you understand. 😊

@discip: This PR is still open & pending, so support will be added in due time.

Thanks! 👍🏻
That's great news! 😊

Wondering if slew rate and current range should be configurable at run time so the user can test noise & heat
