Stealthchop maybe?

This looks brilliant. I will test it as soon as I can.

the esphome AC dimmer has hardware interrupts enabled. If you venture in more accurate timing. I am also working on a driver with precise timing. Progress is slow, unfortunately.

This is no issue, however I chose the Trinamics for their ability to do stealth chops. My machines have to be quiet. Sensorless homing is not possible at the same time. I changed modes for that on a bare metal project. I would love to see this extended.

Great to see progress here!

Thanks!

Are you referring to using interrupts for feedback from the TMC2209s internal step generation for position tracking?

If you are looking for looking for particular configuration options, please take a look at this "advanced mode"
