Any news on that? Is there a workaround possible?

The STM32 version lives in the branch STM32. Did you have a look there? Your PR seems to address the main branch. BTW: the STM32 branch is maintained by @ramboerik....

Interesting, I'll have a closer look in the next days.

The used timers are specific to the processor. Unfortunately the LC has a limited set of timers so that won't work out of the box. It might be possible to...

There is a very first experimental version here: https://github.com/luni64/TeensyStep4

It should be working in principle (used it in a small project) but there certainly will be bugs.

I'd like to reproduce that. Which sketch did you try to compile? Which build system are you using (Arduino/PIO/VisualTeensy...)?

Do you have the current Teensyduino installed?

Not directly and probably the rest will run, but I can't guarantee. I can have a closer look if you tell me which version of Teensyduino you use.

You can plug in your own accelerator, no need to change the lib. Since the accelerator doesn't need to calculate anything, this should be quite simple. Here some **untested** code:...
