Using FOC SDK

The FOC library is complicated and I have some difficulties to understand how to work with it. Even after reading UM1052, UM1053.

On the highest level we can start/stop a motor

if (MCI_GetSTMState(oMCI[M1]) == IDLE) { MCI_StartMotor(oMCI[M1]); } else { MCI_StopMotor(oMCI[M1]); }

But how to set velocity and current?

Another question - I have to drive DC motors as well. What should I set for this purpose?

Is there more extensive examples?

For the second question, did you mean  brushed or brushless DC motors

PMSM FOC library is for driving the brushless ones.

I need to drive DC motors as well as BLDC. So I thought there is a way to set the firmware to behave like a full bridge driver.

I don't think FOC SDK is applicable for driving Brushed DC motors. The poles in Brushed motors are mechanically commutated vs the Brushless ones where we need complex algorithms to commutate motor windings.

If you do need an intergated solution, take a look at this document:

The question has been moved from the "Motor Control Hardware" section to the "STM32 Motor Control" section (the question is about the STM32 MC SDK).
