SPI encoder implementation.

[JStrz.1]

Hi

I am looking for hints - how to implement the encoder from which I read the position via SPI?

Should I set the encoder with index in Motor Control Workbench? If so, where to write the position read after SPI to "pretend" an ordinary encoder? I also see that the encoder index (Z) raises an exception - this is where the motor speed is taken? Generally I want to use the motor in position mode with torque control.

Have any of you already run the SPI encoder with MCW?

Does the encoder have an SP interface? They typically do not.

Of course the encoder has an SPI. It's AS5147. I wrote a library for it and works beautifully in SPI interrupts with F446.

My question is where to overwrite current angle values in MCW generated libraries? And since it needs position control, I assume that the original encoder setting with index a is correct. However, for the proper operation of the application, I must replace the counting of pulses from the encoder by systematically substituting the angle value readed via SPI. Initially looking at the code, but I'm starting to wonder if I need the Motor Control Workbench in FULL version?

And if so - what are the conditions for receiving it? I applied once and was rejected.

Hi JStrz 1, I am also using same sensor but with stm32g474 MCU. Can you please send basic working Library AS5147 to [e-mail]
