And also how can i find FOC GUI software?. I downloaded for along time ago. But it is not available any more?on ST site.

Hello,

FOC GUI refers to sensorless control of brush-less BLDC motor. Is that what you ment?

By the way, it's still on the web, you can find it for instance at

first off all you must use single pwm channel to drive power mosfet with a mosfet predriver. ifyou want control direction another output pin can be arranged for direction information. in that case you must use a hbridge dc motor power circuitry.if you want control mmotor torque adaptively you can add a resistor between ground and mosfet. and you connect that pin wit a suitable current sense amplifier circuitry to adc input of mcu. you ccan change pwm freq according to current across on motor.

there a a lot of simple aplication codes at section examples library adc and pwm. you can adapt that codes for your aplication.
