[FEATURE]Dshot & Bi-directional Dshot support #431

Open lida2003 opened 2 months ago

lida2003 commented 2 months ago

Describe the solution you'd like Support Dshot & Bi-directional Dshot like AM32, https://github.com/am32-firmware/AM32/blob/main/Src/dshot.c

Hi,

This is a motor control library, I am not sure a communication protocol belongs here. Ideally someone would create a library for dshot, have you checked if there is one already? There are libraries for other protocols.

I'm with Candas on this - it's unlikely we would add Dshot support to the core library.

But we would be happy to add it in our drivers library if the implementation can be made in a fairly simple way without external library dependencies.

Otherwise, I think a seperate project would be best, which we would be happy to host/fork in the simplefoc organisation.

Note: I think it would be an interesting addition for sure, I have been looking at this and ExpressLRS and it would be cool to have a simple to configure setup for people to use in combination with controlling SimpleFOC.

Looks like it requires timers + DMA. An example here : https://github.com/mokhwasomssi/stm32_hal_dshot So this would required separate implementation for arduino,stm,esp, ....

The repo was added a long time ago. When I posted this issue, I hadn't realized that this is a FOC (Field-Oriented Control) library.

Currently, AM32 uses sinusoidal control. And I think it would be better to use FOC control. Is there any project(firmware) for Arduino-FOC library used for FPV ESC?

Yes.
