hello st community!I installed today STM32CubeIDE Version: 1.17.0 Build: 23558_20241125_2245 (UTC). I want develop the firmware for a motor controller with the stspin32g4 mcu. i cant select this mcu in the target selector for the new project. why did the people at st.com not have this mcu in the target selector?what is a work around? i already run a serach for updates but it came back with no new updates.should I select a G431 mcu? but I think the pin config will be different then. i have 5 mcu stspin32g4 here.and the datasheet look like they are perfect for a small esc because the stspin32g4 with 170MHz has enough power to run FOC. and the BOM and pcb is small. thank you if you can help meFrank

 I am trying to connect a Nucleo-F446RE with an X-Nucleo-IHM08M1 to the Motor Pilot from Motor Control Workbench 6.3.2. When I manage to open the VCP on the ST-Link, Motor Pilot tells me to configure the board. I have tried all baud rates, changed cables, and even replaced the Nucleo board, but I keep encountering the same issue. Am I missing something? Additionally, I am having trouble finding proper documentation for this version of the Workbench (6.3.2).

Dear All, The IPMlnmx decoder on the STEVAL-IPM30B board—what is its function?I cannot find any relevant documentation about it.Does anyone know?  Best Regards, 

Hello Everybody,   MCSDK:6.3.0 CubeMX: 6.3.0 Workbench : 6.3.0 Cube IDE : 1.15.0 Power Board : IHM08M1(Rshunt=0.01Ω) Control Board : NUCLEO-G431RB Motor : BLDC 26w 24v/8 pole pairs / rpm=4k / rated current=1.8A/hall sensor   I am currently testing the use of STC_ExecRamp(). In WORKBENCH, the default speed is set to 1000. However, when I call STC_ExecRamp() in the code and change the speed to 500, the readback speed is still 1000. I have set it to Speed Mode. Could anyone point out what might be wrong?

MCSDK:mdsdk6.3.1 In the decoupling term calculation of the current loop, is there an error? welecT is of the fixp30_t type, while the compensation term uses FIXP_mpy(upQ, welecT). The result obtained in this case should still be Q30. Should FIXP_mpy be changed to FIXP30_mpy?   

MCSDK 6.3.1Does the HSO algorithm in FOC support IPMSM motors? I see that in the MCSDK software, i can select IPMSM, but the generated code does not include ld and lq. Does this mean the HSO algorithm can only be used with SPMSM? 

I can't see the dead time between the signals of the high and low MOSFETs of the same phase on the oscilloscope. The motor runs properly without load, but when a load is applied, the high and low MOSFETs of the same phase burn out. Photos and software are below. I'm using six-step   

I am using the EVLSPIN32G0A1 board to control a BLDC motor with the FOC / 6-step (trapezoidal) commutation algorithm with Hall sensor feedback. I have a few questions regarding its implementation and customization:1. Potentiometer Default Function: What is the default purpose of the potentiometer in the provided firmware? Does it control motor speed, duty cycle, or another parameter?2. Commutation Timing: How does the default firmware handle commutation timing? Is it based on Hall sensors, back-EMF detection, or fixed timing?Where can I get detailed information about this in the documentation? Thank you.

Hello I had error during program generation at MC Workbench I attached the error log Please, let me know what is the problem kindly.Thanks SY 

We are trying to control a 24V PMSM using ST Motor Control Workbench (MCW) version 6.3.1 with the FOC in order to control a sliding door. We are using “Position Control” as the control mode.We are using Nucleo-G474RE, STEVAL-IHM023V3 and X-Nucleo-IHM09M2 boards.PMSM has 10 pole pairs and there is a 1024 ppr incremental quadrature encoder on it.So far so good, but recently we noticed that in some cases the encoder alignment was not complete. Namely; when the sliding door is completely closed and we energize the motor, the encoder cannot align and motor stucks. However, when we do the same process with a minimum 5 mm gap, there is no problem.From what we understand here, in order to align the encoder, the rotor needs to be rotated a little depending on the position of the magnets and therefore the rotor. We consider this issue to be a situation that may be encountered during normal use. Do you have any advice?Would changing any parameters in the Speed ​​Sensing Configuration step of

Hi, I have been working with the HSO motor control algorithm using Motor Workbench 6.2.0. I was able to successfully configure the firmware for a custom PCB, and it works correctly. The motor, which is a PMSM with 2 pole pairs, starts and runs without any issues up to 30,000 RPM using the HSO's speed mode.However, as I increase the bearing friction to test the maximum load at which the motor can still start, I notice that no matter how much I increase the application's maximum current, it is not applied right from the beginning by the algorithm in situations where the motor is unable to mechanically move the shaft.Specifically, I observe that from the start and for about 700ms, the algorithm applies a current equivalent to 70% of the maximum application current, and even though the shaft doesn’t move, the algorithm’s estimated speed increases linearly up to 3,000 RPM.In this regard, after reviewing the configuration parameters in the firmware, I am wondering how the following are calcu

To clarify the details about my environment:STMC Board Designer v1.0.0Motor Control WorkBench v6.3.2Now to my question:For the STSPIN32G4 Eval board example, the PE15 Pin is assigned for driver protection trigger input.This makes sense, because the datasheet of the STSPIN32G4 also indicates PE15 as the internally connected fault timer input pin. But when I try to create a custom inverter board, I can only select pins that are also available on the package itself.Since PE15 is only internally connected, I can't select it.How can I assign the pin in the board specification?Any help is welcome :)Best regards,Daniel    

I ordered an STEVAL-ESC002V1 board (not yet received) and I'm unsure on how to upload the firmware.I believe it will be through ST-Link but will I need any special hardware for it, or a serial port will do ? 

Hi,I'm working with L6472 (custom shield) with an NUCLEO-H563ZI under zephyr OS.I'm facing out some issues with reading the register ABS_POS. I send  Goto command to the driver to move it from initial position 0 to position 3200. After the command is sent, the motor start moving to the good position but when I read ABS_POS register the driver send me the position 3072.After multiple try, I notice that when the bit 7 (that represent 2^7 = 128) of the desired position is high the ABS_POS doesn't contains the correct value. Even if I write  directly on the ABS_POS, when I read data this is not the good value.I attach my code and a screenshot to make sure you understand what I'm doing.  /*Get innitial position position*/ int32_t AbsPos = l6472_GetAbsPos(); printf("\033[0;33mInitial position: %d (hex = 0x%X)\033[0;37m\r\n", AbsPos, AbsPos); /*First move going to ABS_POS = 3200 steps from ABS_Pos = 0 steps */ posSend = 3200; l6472_GoTo(posSend); while (end != true

Using Workbench 6.3.0.Creating an "inverter" board for a custom board which uses a 25MHz crystal. Only 8, 24, and 48 MHz crystals are offered in the dropdown. Can I edit JSON file to "clocksource": "25_crystal"? If not can I edit the CubeMx clock? Can MCSDK firmware be made to work correctly with a 25MHz clock?

Hi,I want to use STEVAL-FCU001V1 Board as Flight controller unit MCU, I want to drive BLDC motors; for that purpose, want to connect a different ESC to Drive motors than STEVAL-ESC001V1 board. Is STEVAL-FCU001V1 Board is compatible to drive other ESCs?Because we have selected a motor, and it has an ESC suggested for motor. We want to use the same. So Shall I connect PWM signal from STEVAL-FCU001V1 to External ESC? 

Hi ST Team, I'm trying to use this discovery kit at the moment to try control a brushless dc motor, so I would like to profile the motor performance but I'm stuck with trying to configure the board/setup despite following the instructions (UM2516 - with daughterboard not removed setup) already on the data sheet.

Dear community I would like to ask regarding ADC raw value for current sensing in STSPIN32G4. As we can see on below image the raw value of ADC1 CH3 and ADC2 CH12 is always in range of few hundreds. FYI, the motor is in rotating mode. We can see from the PWM duty cycles, it is changing every time.When measured using multimeter for phase current W, the current is always alternate from +3.5A to -1.2A which make sense. but the ADC raw values keep in hundreds. I was expecting it alternate from > 2048and < 2048.ADC resolution is 2^12.2048 = 0A // >2048 = +A //2048 = -ABut the ADC readout values are always less than 2048, or more specifically, they fluctuate between 172 and 208. Can you help to advise on this weird raw ADC values? below is my multi-channel ADC1 settings.We have also tried changing the ADC alignment to right-aligned, but instead, the values dropped to only two digits.We have attached our ADC.c file. Could you kindly point us in the right direction?Any guida

The document UM1949 says:The original firmware demonstration to reprogram the STM32 MCU of theP-NUCLEO-IHM001, is available in binary file format from the www.st.comwebsite and it is called P-NUCLEO-IHM001.bin.Also where is the source code for that firmware?

I am trying to find a way to limit the total electrical power of the system when driving the motor in speed control mode.With the help of API functions I can get the current power of the system:Power_W = MPM_GetAvrgElMotorPowerW((MotorPowMeas_Handle_t*) pMPM[M1]);I can also get the battery voltage:Vbus_V = (PQD_MotorPowMeasM1.pVBS->AvBusVoltage_d * (ADC_REFERENCE_VOLTAGE / VBUS_PARTITIONING_FACTOR))/65535;and from this monitor the battery current as I = P/U.But the question is how can I apply this so that my battery current never exceeds, for example, 10 amps or the power never exceeds 150 watts? Is there a technique for how I could limit exactly these energy parameters of the system?Standard APIs* - MC_ProgramSpeedRampMotor1()* - MC_ProgramTorqueRampMotor1()does not do this in any direct way, and the general initialization of the system allows you to limit only the phase current of the motor, but the phase current is not directly related to the energy parameters of the system.I am

Hello Everyone,We are working on a motor control, inverter drive strategy demonstrator unit using an STM32 MB1136 C-04 board.To start, we have a legacy example program for motor control, for which I could get the properly old CubeMX version, bit it also requests the mentioned older MCSDK_v5.2.0 software package, which I could not find online.Could anyone maybe send over the properly old SW package?Thank you in advance!
