Getting started with X-CUBE-SPN14 stepper motor driver
software expansion for STM32Cube
Introduction
The X-CUBE-SPN14 expansion package for STM32Cube gives you full control of stepper motor
operations.
When combined with one or more X-NUCLEO-IHM14A1 expansion boards, this software allows a
compatible STM32 Nucleo board to control one or more stepper motors.
It is built on top of STM32Cube software technology for easy portability across different STM32
microcontrollers.
The software comes with a sample implementation for one stepper motor. It is compatible with STM32
NUCLEO-F401RE, NUCLEO-F334R8, NUCLEO-F030R8 or NUCLEO-L053R8 boards with an
X-NUCLEO-IHM14A1 expansion board mounted on top.
