STM32 MCUs Motor control

Hello everyone,I am experiencing an issue with MotorPilot on a new laptop.Problem descriptionWhen I start MotorPilot, the application window opens but:I can only see a black screen whit a white arrow the content is flickering no GUI elements are visible or usableThe issue only affects the application window, not the whole system.System informationOS: Windows 11 Laptop: New system (Intel Core Ultra 7 255HX + RTX PRO 2000)Additional observationsThe program seems to be running, but the UI is not rendered correctly This looks like a graphics / rendering compatibility issue Problem occurs only on the new laptop (older systems worked fine)What I already triedRunning as Administrator Disabling fullscreen optimizations(no improvement so far)Has anyone experienced the same issue with MotorPilot?Is there a known workaround? Can hardware acceleration be disabled? Are there recommended settings for modern GPUs?Any help would be appreciated.Thanks!  

Is this parameter dimensionless or in volts? I've tried many values, but I keep getting a yellow warning icon indicating an error, such as with 0 or 1 or 1.65 or 0.5 

I started with the MC workbench and installed X-Cube-MCSDK Version 6.4.2. After installation the MC Workbench is opened, but the dialog is complete empty (except the caption). The behaviour is the same if i start the workbench via the desktop icon or as administrator.

Dear ST Support Team,I am working on a custom BLDC motor controller using STM32G431CBU6 with STM32 Motor Control SDK 6.4.2 and DRV8316CT motor driver.I have created custom Control Board and Power Board JSON files using the Motor Control Board Designer. However, I am facing an issue configuring the current sensing topology for FOC.Hardware ConfigurationMCU: STM32G431CBU6 MCSDK Version: 6.4.2 Motor Driver: DRV8316CT Control Algorithm: FOC PWM Configuration: 3-PWM (TIM1) Current Sensing: Three Shunt Resistors (Amplified)Current sensing connections are:Signal MCU Pin ADC Function CURRENT_AMPL_U PA1 ADC1_IN2 / ADC2_IN2 CURRENT_AMPL_V PA2 ADC1_IN3 CURRENT_AMPL_W PA3 ADC1_IN4 ProblemWhen I configure Three Shunt Resistors, Motor Control Workbench reports the following warnings: CSConnect: ThreeShunt_AmplifiedCurrents DualADCs SharedSignalCSConnect: ThreeShunt_AmplifiedCurrents DualADCs NoSolutionI investigated the ParameterConnection.json file and found that the DualADCs im

Hello ST Community,I am working on a BLDC motor control project and would like to use STM32 Motor Control SDK (MCSDK) Workbench to generate firmware.My Hardware ConfigurationMotor Type: BLDCMotor Voltage: 48VMCU: STM32F405RGT6IssueWhen creating a new project in MCSDK Workbench, I cannot find my exact board/MCU configuration in the board selection list. Since the STM32F405RGT6 board is not available in the predefined options, I am unable to proceed with the standard project generation workflow.QuestionsIs STM32F405RGT6 officially supported by MCSDK Workbench?If yes, how can I create a project for this MCU when it is not listed in the board selection menu?Is there a way to add a custom board definition?Where can I obtain the required board configuration/JSON file (if available)?Can an existing board configuration be modified to support STM32F405RGT6?If MCSDK does support this MCU, what is the recommended procedure for configuring:PWM generationCurrent sensingHall sensors / Sensorless con

I encountered a problem where I used ST's open-source FOC algorithm. Currently, my motor often shakes at a speed of 22k. Upon inspection, I found that the Hall output of the motor has some fluctuations, which is a problem with the motor itself. However, the important issue is that when the timer input captures the Hall sensor signal, there is a problem where both the capture value of 65535 and the overflow flag exist. As a result, the calculated capture value becomes 65535+65536, causing shaking. I think it's because when 65535 was captured, the program didn't process the callback function in a timely manner and only processed the timer callback function after overflowing. What if we solve this problem?As shown in the blue curve in the figure below, when a peak appears, it is an abnormal moment： 

Hi everyone,I am using an EVSPIN32F06Q1S1 board to drive a turbomolecular pump motor. Since the exact motor was not available in Motor Control Workbench, I imported a different motor and manually updated the parameters.The project was generated using MCSDK with FOC + Sensorless Observer (STO+PLL) and flashed successfully. Motor Pilot connects correctly, and VBUS is reported as approximately 316 VDC with a 220 VAC input.However, when I press Start in Motor Pilot, the motor does not start and I receive:MotorControlProtocol: ASPEP_RESP ERROR: CMD_NOKThe state eventually changes to FAULT_NOW, but no detailed fault information is shown. Motor Pilot also reports several register access warnings such as:Accessing register [...] resulted in error[5]although communication with the board remains active.At present, no motor is connected to the inverter. We are trying to verify the controller operation before connecting the actual turbomolecular pump.My questions are:Is it expected for an MCSDK se

 Hello,I have inherited some code where a 5kHz 50% PWM is output in center aligned mode using TIM1. CK_PSC is 275MHz, CK_CNT is 137.5MHz (I think) because PSC = 1.The pattern output matches the implementation:  The yellow trace is a GPIO pin that is toggled in the ISR HAL_TIM_PeriodElapsedCallback(). I want to to keep the same 50% duty but half the frequency to 2.5kHz using the prescaler.From the TRM, it seems I just have to modify PSC from 1 to 2. However, when I do this by poking the SFR register using the debugger, I get the following output:  As you can see, the PWM ratio changes but the frequency does not. I’m at a loss to understand why. So would be grateful for any suggestions.Thank you. In case it helps, here’s my register dump. I have no idea what DMAR is that is my next step.  

Hi, Could you please explain the proper command sequence for smoothly transitioning a motor from Forward to Reverse operation?Currently, my sequence is:STOP → DIR → SET_SPEEDThis assumes the STOP command was issued while the motor was already in the RUNNING state. However, with this sequence, the motor will not reverse direction. The only sequence that consistently works is:STOP → DIR → START → SET_SPEEDWhile this does reverse the motor, I'm running into another issue: every time I issue a START command (this applies at any given point in time), the motor immediately accelerates to approximately 2000 RPM before settling. After that, SET_SPEED commands work as expected.Is there a recommended sequence for changing direction, or is there something I may be overlooking in my implementation?Any input would be greatly appreciated.Thanks. 

I am working on a project to drive a door using a PMSM motor in position control mode. I am trying to add an emergency brake function. In an emergency, when the operator pushes a button, motor should brake and then return to its starting position without harming anyone.I know there is PWMC_TurnOnLowSides() function (https://community.st.com/t5/stm32-mcus-motor-control/how-can-i-stop-the-motor-urgently/m-p/597309#M8287 ). But it is just stopping the motor, not braking. I have tried this function.As far as I know, there is no such API in position control mode.If I am wrong, is there an API to brake the motor in an emergency? Can anyone help me? Do you have any advice for me?Any information you provide will be welcomed.   Project:ST MCW Ver             : 6.3.2STM32CubeIDE Ver : 1.18.1Driving algorithm      : FOCControl board            : Nucleo-G474REPower board        &

I use STM32F407VG Discovery evolution board to drive genuine BTT TMC2209 v1.3 motor drivers and NEMA11 motors. There are 4 TMC2209 drivers. I am using bare-metal CMSIS custom firmware.  Motor power rail is 24 volts, logic voltage is provided from a stable power source. The issue is whenever the Discovery board is power reset motor operation stuck, only first motor, M0 is working. In this stage STEP, DIR, UART, Enable operations are working fine (I use USB communication with Raspberry Pi and communication also work fine). After motor power rail is hard reset it will start to run all motors. Anyone faced this issue and a solution?

I know that Motor control workbench is only available on Windows but I hoped that it would be possible to open the generated .ioc file from Linux. I tried it and I got this error. Can this be fixed or I cannot even open the STM32CubeMx project from linux?  

I am using IHM.08M1 with nucleo.stm32g474.I’ve decided to try lowering this parameter from 2275 rpm (maximum motor speed) to 250 rpm (maximum speed for my application): As you can see, when I change the value, an error in Speed Sensing Config appears: The auxiliary sensor section is not active!I don’t understand where the error lies.Any value lower than 1600 rpm gives me an error; I don’t understand why

In this documentation, I can find a detailed description of the torque/flux (current) PI controller implementation, but there is no clear explanation of the speed PI controller design or tuning. Could you please explain how the speed PI (KP, KI) is derived, and what criterion ST MC Workbench uses to compute these parameters automatically? 

Hi,I am trying to establish CAN communication between a NUCLEO-G474RE and a YMMOTOR MS72450 motor controller using the FDCAN1 peripheral.HARDWARE SETUP:- STM32 NUCLEO-G474RE (STM32G474RETx)- Transceiver: WCMCU-230 (SN65HVD230), 3.3V, connected   to PA11 (FDCAN1_RX) and PA12 (FDCAN1_TX) via AF9- Motor controller: YMMOTOR MS72450 (CAN 2.0B, 500kbps,   standard frame, Motorola byte order)- Termination: 120 ohm on motor controller side (factory   default built-in). 120 ohm on transceiver side.- Common GND connected between STM32 and motor controller- Motor controller ACC pin (pin 10, 48-85V) is poweredCLOCK CONFIGURATION:- HSI 16MHz -> PLL -> 170MHz system clock- FDCAN kernel clock = PLLQ = 170MHz- NominalPrescaler=17, TimeSeg1=15, TimeSeg2=4, SJW=1- Calculated bitrate = 170MHz / (17 x 20TQ) = 500kbpsSYMPTOM:- Green LED blinks initially = TX frames being queued   successfully (HAL_FDCAN_AddMessageToTxFifoQ returns HAL_OK)- Oscilloscope on CANH/CANL shows clear CAN signals from   the

We are using the EVSPIN32F06Q1S1 board and have configured TIM1 PWM outputs as CH1/CH1N → PA8/PA7, CH2/CH2N → PA9/PB0, and CH3/CH3N → PA10/PB1. While probing the board, we observed PWM waveforms at test points TP1, TP2, and TP3, which according to the documentation are connected to RES1, RES2, and RES3 rather than to PA8, PA9, and PA10. The complementary outputs are also present and behaving as expected at their respective MCU pins. Could you please clarify how the TIM1 PWM signals are being routed to TP1–TP3 and whether RES1–RES3 are internally connected to the TIM1 outputs on this board?

Subject: MC Workbench 6.4.2 — Custom Power Board JSON: 'No algorithm available' and missing connection paths errorDear ST Motor Control Support Team,I am writing to request help with creating a custom power board JSON template for MC Workbench 6.4.2.I have a custom BLDC motor control board using the TI DRV8316CT 3-phase integrated FET driver connected to a NUCLEO-G431RB (STM32G431RB). I have created a custom power board JSON file and placed it in the boards/power/ folder, but when I select it in MC Workbench I get the following errors:1. "Mandatory Phase Voltage Generation feature is not defined or there are not connection paths between hardware signals and relative MCU resources for the feature."2. "Mandatory Current Sensing Feature for FOC/HSO algorithm is not defined or there are not connection paths between hardware signals and relative MCU resources for the feature."3.

After creating the project from Workbench, I discovered that pins PA14 and PA13 in CubeMX were not working. I checked the Workbench settings again but couldn't find any parameters related to this issue. Without these pins, the motor cannot communicate. I also tried manually configuring them and the motor worked, but I think the Workbench setup would be better.Schematic of B-G431B-ESC1 discovery kitCube MX  

Most of the default settings on the ST workbench for the Charge Boot Capacitor Time are 10ms. However, with the B-G431B-ESC1 Discovery kit with STM32G431CB MCU, calculations show that the charging time for a 1-microfarad capacitor should not exceed 10 microseconds. So why is the default setting 10ms?
