Re: [CAD_CAM_EDM_DRO] brushless servos without hall commutation

Interesting appnote.

Unfortunately, all of the examples require hall sensors for
commutation. There is a short section on using an encoder for speed
measurement, but not for motor position sensing (and especially not for
unknown startup states, which they don't really go into at all)

Still a cool chip though.
