dc stepper motor

[NASOK.1]

I am attempting to control the speed of a DC stepper motor using an Infineon TLE8444SL motor driver. The four outputs of the driver are connected to the motor, with inputs 1 and 2 shorted and connected to pin Pa1, and inputs 3 and 4 shorted and connected to pin pa5 of the nucleo f401. I have successfully achieved motor rotation in both clockwise and counterclockwise directions. What steps should I take to control the motor speed through PWM, and which pin should I configure for PWM?

Hello @NASOK.1 ,

I suggest you our video Stepper motor basics where you can find more info on stepper motors driving.

In the ST portfolio you can find different stepper motor driver, for easy driving I van suggest you the STSPIN820
