Question

Is there a way to use absolute encoders/resolvers with the Motor Control SDK?

The Workbench can only generate code for sensorless or quadrature/hall sensors. Can the controller be fed with position values (received via SPI for example) or is this not intended?

My particular usecase is: The motor to be used has a BISS encoder and is intended to be driven slowly, but precisely. hence it would make sense to use the BISS encoder.

Hello Leonlf,

Yes adding resolvers is part of our roadmap.

Thanks and best regards,

Claire

The sdk datasheet implies user-made encoder code. As the quadrature encoder code is _weak attributed, can I just override the getPosition methods?

Would the delay disturb the controller?​

Dear @Leonelf​ 

Do you have still this problem to solve?

And just in case, if not, do not hesitate to share the final solution you found.

Best regards

Dear  @Leonelf​ 

Could you give more details to the STM32 Community about your setup -the material you use- (HW and SW, CPU(s), tools and versions, board(s), motor(s) and so on)?

And more especially did you use MC tools (such as MC_suite, MC-Motor Profile, MC-SDK, MC-workbench, and so on)?

Best regards

Dear @Leonelf​ 

As you do not answer, I guess you don't have to solve this problem anymore, therefore I consider this thread closed.

If not, feel free to reopen it by posting a new answer.

@Laurent Ca...​ 

I'm looking into the same use case for an absolutt biss encoder as @Leonelf​ . Do you have any updates regarding an "absolutt encoder implementation" in the STM firmware?

thanks

mr. andy

Dear @mrandr​ 

It is a rather old question.

Please open a new one in adding reference to this one.
