X-NUCLEO-IHM01A1 and development board

Hi STM,

I am having NUCLEO-476RG and I am planning project with steppers (by using X-NUCLEO-IHM01A1). Can I connect this expansion with my development board. And also, what is the maximum number of expansion boards I can connect to the development board. I am asking that as my project should use 7 motors?

Regards,

Aleksandar

    Yes, in principle you can also operate the X-NUCLEO-IHM01A1 with the NUCLEO-L476RG. It would make sense to use the software package X-CUBE-SPN1, because you can start immediately with it. It doesn't contain a finished project for STM32L476, but the libraries are already included for STM32L4, so they can be adapted relatively quickly.

    Regarding the second question about the number of expansion boards: a maximum of 3 boards per SPI channel can be controlled in daisy chain. Theoretically, you could also connect more X-NUCLEO-IHM01A1, but this would require more extensive reconfigurations in order to control the additional boards via a second and third SPI port of the STM32L476.

    Does it help?

    Hello, the MCSDK only supports FOC and 6-Steps algorithms.
    The stepper is therefore not supported on MCSDK but you can find more information on this page about the steppers:
    https://www.st.com/en/applications/industrial-motor-control/stepper-motor-control.html#overview
    Therefore the NUCLEO-L476RG board can be used on MCSDK to the motor control for FOC or 6-Steps algorithmes.
    And we will soon be able to have dual motor control with a single board on the next release.
