Drive bipolar stepper motor with X-nucleo IHM05A1 stacked on arduino uno?

Hi everyone, thanks for welcoming me here.

I started a project where I have to drive a bipolar stepper motor.

I must use an arduino Uno with a x-nucleo-ihm05a1 stacked on it.

I look all day long yesterday for tutorials, schematics, circuits diagrams and code examples.
I found tutorials of bipolar stepper motor with ihm05a1 stacked on stm32 board.

I need somehow to also make it work with an arduino Uno.
My problem is that I don’t understand how to “translate ST code to Arduino code” or to reach the A and B outputs of ihm05a1 with the arduino Uno to control the phases.

Can someone help me to start my project please ?
