How to get STSW-L9907-H , a GUI for EVAL-L9907-H?

Can someone tell me how to download / where to find the GUI (STSW-L9907-H) for the evaluation board EVAL-L9907-H?A user manual (UM2119) is available, but the software itself is missing from the repository. STSW-L9907-H: https://my.st.com/content/my_s...

Motor spins and triggers a fault with STSPIN32F0A and the SPIN3202 6-step library

A few Qs about the 6-step library. I have a 350W, 36V motor that I'm trying to control using the STSPIN32F0A. I've got the 6-step library working ... sort of. The motor rotates for a few moments and then a fault state is triggered (USER2 LED). In the...

X-NUCLEO-IHM15A1 for motor having 5A stall current at 12V

Hi everyone, since i'm new to motor control i have a beginner (i think) question. I'm looking for an expansion and nucleo board for my brush DC Motor(BDC). For expansion i find X-NUCLEO-IHM15A1 but it can power 1.5A for each motor. My motor has a sta...

Do you have any advice which voltage regulator should I use?

Hi to All,I want to make a pcb card which which work with 3.6V. I wil use a voltage regulator to drop down voltage from 10V-17V batteries to 3.3V. Do you have any advice which voltage regulator should I use. I am trying to make a system with lowest p...

Doubts SPV1020, power optimizer

Hello, I am studying DC-DC converters, power optimizers for grid-connected PV.I saw some work with the SPV1020, but it seems to be discontinued. Do you know why? Is there a new version?I would also be grateful if I indicated any evaluation module, th...

Is there a way to default the STSpin840 motor driver to completely shut down the motor from turning upon power up?

I am currently using the X-NUCLEO-IHM15A1 Shield with the NUCLEO_F401RE MCU board to evaluate the use of the STSpin840 Motor driver using a single 12VDC motor. During the programming and debug process the motor will automatically start turning. Beca...

What do I connect pin 2 (VREFB) of the STSPIN840 to when I want to run the two outputs in parallel for higher current capability?

I am currently designing a PCB that will control a single motor using the STSPIN840 (X-NUCLEO-IHM15A1 Shield). The datasheet is pretty good about explaining how to connect things if you want to run the outputs in parallel mode but it neglets to tell...
