X-CUBE-SPN14 Software Description
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.
