Added TMC5160 support

[amken3d]

Requesting review of the the PR to add support for TMC5160. The TMC5160 is a popular stepper driver and is feature packed. This implementation add support to using the TMC5160 using either the UART mode or the SPI mode. The code has been tested to work on rp2040. The smoke tests passed using "make test". The code is not fully tested for all available features of the TMC5160 as it is a pretty complicated piece of silicon.

Hello @amken3d this is a very impressive PR! Thank you for working on it.

I changed the branch for it to dev as mentioned here:
https://github.com/tinygo-org/drivers/blob/release/CONTRIBUTING.md#how-to-use-our-github-repository

Also, I made a comment, although did not have time to look deeply in the new code.

Also, wondering if you could please add a smoketest/example?

Thanks!

@deadprogram, thank you for the kind words.
I have added example code and smoke test as per your suggestion. I hope this adds some value to users. Looking forward to many more adventures with Tinygo.
My go and tinygo journey started about a 2 months ago and I am loving it. My primary reason for switching to go/tinygo is because I am building a Pick and Place machine using go (gocv). I initially wrote the microcontroller code in c++(platformio), but I found it much more ergonomic to use tinygo instead. I do have a couple of gripes we can discuss offline, but overall, I feel like Tinygo is much easier alternative to Arduino/C/C++.

Same comment here as above.

When i do go mod tidy, it automatically upgrades to
go 1.22.1

toolchain go1.23.1

Is there a way to pin it to 1.21? I've tried everything that google suggested and failed

[deadprogram]

I think the toolchain here does not matter to user, so you were fine to run go mod tidy and commit the result. I was incorrect.

The toolchain directive only has an effect when the module is the main module and the default toolchain’s version is less than the suggested toolchain’s version.

@deadprogram : Updated

The file named SPIcomm.go might better named spicomm.go to avoid capitals and also to match uartcomm.go naming.

Thanks very much for this addition @amken3d now squash/merging.
