circuit design problem

Question

hello everyone,

Do I need to pull the three-phase voltage feedback signal back to the MCU in this architecture diagram using the official application?

Dear Eva, there's no need to obtain the voltage of the phases, those current signals are enough to implement the vector control algorithm.
