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...
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...
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...
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...
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...
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...
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...
We are trying to set up a L6472 for step mode control using the STCK pin with limited success. Here is our setup of the registers.CONFIG: 0xFE80Status: 0xFE02STEP_MODE: 0x1CWe are trying to drive the STCK pin with 3.3V LVTTL from a PIC32 at 1250 Hz.T...
I am trying to replicate the circuit given in application note AN2097 which is a 10W SMPS at 12V.I am stuck 5 ohm NTC used in the circuit. Can you tell me the wattage of it. It is very expensive also, please tell me any way to replace it. Please find...
