Hello,

any recommedantion how to implement Resover mode/demon, which units preferale to use for modulation and demodulation resolver signal?

Hi,

do you means resolver sensor, which can provide the rotor position information even if the motor is in still state?

If it is the case, pls refer to the application note.

In the following library, you can get angle based on the voltage of 2-phase coordinator.

Hope it can help you

Yes, I meant RD C resolver to dogital conversion, is it source code available when I need to improve, filter more the SIN//COS and want to build upon existing code?

Hi,

As you know that the resolver sensor is third party product, I suppose there is resolver sensor on market, which can output digital angle directly.

I just browse the product, I do not know the detail, pls check yourself.

Hope it can help you
