STM32 MCUs Motor control

Kindly provide an example code to make my steval esc001v1 to a working ESC for a drone i have configured PA15 as input which accept PWM signal but throttle mapping is not done any help will be appreciated. 

Hello,I am currently evaluating the STM32 G4 platform for motor control. I would like to control 3 motors with one MCU, and I was planning to order: 1 * B-G473E-ZEST1S3 * STEVAL-LVLP011 * B-ZEST-ADAPT13 motorsI have installed x-cube-mcsdk-6.4.2 and tried to create this setup, but I cannot see how to add 3 motors, and how to interface many power boards to 1 control board : The file supporting B-ZEST-ADAPT1 needs to be imported ?The support for 3 instead of 2 motors needs to be done manually (by editing the code) ?The 3 motors will be using biss or ssi so I will have to create those drivers. Are there any other points to check for compatibility ?Thanks for your support

Hi. I want to implement position control, I dont know where to write codes to start motor and write move commands. Please send an example.

I am using Motor Control v6.4.2 to run the motor with the custom board with STM32G4 Series controller with Currents + HALL feedbacks for BLDC hub motors. Currently we are using Main Sensor "Observer+PLL" and auxiliary sensor "Hall Sensor" during STARTUP and Swap these sensors in RUN state.We could see motor is running at a constant speed all the time and not reacting to any change in parameters even after change the requested torq parameters to the torq PI controllers.Questions1 PLL and HALL electrical angles are not in Sync during motor running phase. How can we make the Electrical angle phase shift between HALL and PLL to 0?​​​​​​​​​​​​​​2 Motor Controller is not responding to the update current commands as expected, What Would be the Possible root cause for this kind of behavior?any Help on these is greatly appreciated. Thanks:)-Himavanth

Hello, I would like some help with starting up the STEVAL CTM 015A1. I use an external power supply on terminal CN6. I supply a constant power supply from 0 to 32V on terminal CN5, but the fault diode D10 is constantly on when it is compressed with the STM32CubeProgrammer, then it goes out. I also have Hall sensors connected for the position of the rotor of the SRM.

I’ve noticed that the order of the registers seems to matter. I would like an explanation as to why this is the case and if there is anything documented on this front.Specifically if you want to request the following registers: 25, 89, 1425, 2649, 7001, 73It appears that for some reason or another 73 must be last. If you request the above registers with 73 being anywhere but the last register it seems to cause the G4 to lock up and stop responding to any MCP or ASPEP commands. You also seem to be unable to recover without power cycling the core.Valid Order: 25, 89, 2649, 7001, 1425, 73->e9 00 00 b0->11 00 19 00 59 00 59 0a 59 1b 91 05 49 00<-4a 01 00 f0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 2e 00 00 00Invalid Order: 25, 89, 73, 2649, 7001, 1425->e9 00 00 b0->11 00 19 00 59 00 49 00 59 0a 59 1b 91 05No response and the G4 hangs...Somehow it seems that the ST Motor Pilot is aware of this as it does place all the STATE register last in the packet.Motor Pilot v6.4.

Hello,I am using:Motor Control Workbench/X-CUBE-MCSDK 6.4.1 STM32G474RETx, 170 MHz EVLDRIVE102BH FOC with three-shunt current sensing A2212 13T, seven pole pairs I cannot find the High-Speed Observer, HSO, option in Motor Control Workbench.HSO is not visible or selectable in Motor Control Workbench. The same result occurs with a one-pole-pair, 24 krpm HKP Y0H0-A11 motor. Could you confirm:Is HSO publicly available in MCSDK 6.4.1? Is EVLDRIVE102BH supported? Which reference board should be selected? Is a particular MCU, motor type, sensing topology, or project type required? Is there a working HSO example project that I can import and run? Where exactly should HSO appear in the Workbench user interface?

I am using TIM1 CH1 in PWM mode with the TIM1 repetition counter (RCR) to generate a finite number of STEP pulses for a stepper motor. The desired step frequency is calculated from the motor speed, and ARR/CCR1 are configured accordingly. RCR is set to steps - 1 so that the PWM should generate the requested number of periods and then stop.I am using HAL_TIM_PWM_Start() and the TIM1 update interrupt to detect when the required number of pulses has completed. The update callback is working correctly and HAL_TIM_PeriodElapsedCallback() is being called at the expected completion point.However, TIM1 CH1 is not generating the PWM pulse train correctly, or in some cases no PWM is visible at all on the output pin. I have tried configuring PSC, ARR, CCR1, RCR and the update event/flags before starting PWM, but I am still unable to get the finite number of PWM pulses reliably.I have attached my motor_driver.c file for reference. Could you please review the implementation and let me know if I am

While driving STM32303E-EVAL with STEVAL-IPM20B in sensorless (Observer +PLL) foc mode , speed feedback occurs at below 400 RPM and motor stops. 

i started working on the B-G431B-ESC1 board with a 2836 motor but it would not start. so i started looking at the setup and tried different configurations but no luck. the profiler would not run the motor either. after i disconnect the motor and removed the bus voltage, the Iq in the motor pilot still shows significant numbers.. i wonder if this is a sign of damaged board?   

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!  

I am having trouble generating an HSO based project.  I have already confirmed the board works with “Observer+PLL”.  When switching to HSO I am able to select it in the drop down, at which point it:1. Resets my current sense gain (should be 50), I have no issues replacing this value.2.  Under Speed Sensing I am provided with an empty Current Scale box, which is a “required field” however upon entering a value it remains red and tells me I cannot enter a value, as “no value is allowed”. Is this a bug or have I configured something incorrectly?  It also seems odd that the current gain setting is cleared, although I can edit that without issue.  

I have a motor whose phase resistance is 40 mΩ at 20 °C and 45 mΩ at 70 °C. When I set the phase‑resistance parameter to 40 mΩ, the motor operates normally at around 20 °C. However, when the motor temperature rises to approximately 50 °C, frequent start‑up failures occur. How can this problem be resolved?

I am developing a control board based on the STM32G474RE microcontroller. This board is self‑designed using Board Designer within Workbench 6.4.2. After configuration and project generation in Workbench, the generated project works fine. The HSO option can be enabled, and no errors or warnings are reported for all parameters. Compilation in MDK‑ARM completes without any issues. I have reviewed the initialization code for ADC1 and ADC2, which are used for phase‑current and phase‑voltage sensing. In principle, the HSO measurement mechanism relies on synchronization with the PWM signals. The PWM waveforms are generated by TIM1. However, I observe that TIM3 is configured as the input trigger source for the ADCs in the initialization code, instead of TIM1 as I expected. Is this a bug in the code‑generation output? Please provide assistance.今天 11:32聊聊新话题

Hi,I'm trying to setup HSO on the G431, I used the B-G431B-ESC1 board as a starting guide. I'm trying to use differential sensing with internal OP-AMPs and internal PGA. I have split the currents and phase voltages across ADC1 and ADC2 but I still cannot get the HSO option to show up with MC workbench. I'm using the latest version. I have attached my board JSON file, any guidance will be appreciated.Thanks,Ray

I attempted to create a new Motor Control Workbench project selecting Controller B-G473E-Zest1S and EVLDRIVE102BP. This combo pops up error window preventing project creation…   Errors   BusInterfaceConnect: SPI_FullDuplex_SWnSS No IP matches all signals requirement   General: Interface STDrive102Interface not found in BusInterfaceArray   General: Interface STDrive102Interface not found in BusInterfaceArrayI had previously used the EVLDRIVE102BP connected to P-Nucleo-IHM-03 with no trouble. Now I wish to upgrade my design with G473 or G474 to handle HSO or future ZEST.What’s my best course of action to fix that error and get the board combo working?Alternatively I could base my design on the standard ZEST Kit with STEVAL-LVL01A and upgrade the MOSFETs for higher current.Please advise...

I purchased the EVLGANSPIN2-3PH evaluation module. I added a definition for this module in the MCSDK. I connected a BLDC motor from a well-known drill operating at a nominal voltage of 230VAC to it. I measured the resistance and inductance of the windings, as well as the number of poles. The code was generated in MCSDK v. 6.4.2 in FOC mode with the profiling option – it can only be generated in STO-PLL mode, so the HALL sensors are not used. The PWM frequency is 10 kHz, and the overcurrent control option is enabled.I started all tests at 70 VDC with a limit of 800 mA.After starting the profiler, the motor hums quietly for a moment, and profiling freezes at about 30%. I can't get the profiler to work properly.I started the MotorPilot, and the motor only squealed. Current consumption is about 250 mA.Redesigning the project to STO-Cordic mode allowed the motor to start in MotorPilot. It starts slowly but smoothly and gains speed. The current draw also increases until it reaches the power

Hi everyone,I am currently testing the Current Regulator Step Response as described in the ST Motor Control documentation.I do get the sharp edges, but I see short peaks/overshoot in the current waveform.  Setup: Custom Board → EVSPIN32G4 has been taken as reference Step‑test configured exactly as in the document 3‑shunt topology PWM frequency: 20 kHz BLDC Motor  Motor Control Part3 - Troubleshooting and fine tuning_v2.pdf - Google Drive  What could be the reason for the peaks?  

Hi there, I am after some advice on the best way to implement an FOC BLDC controller on an STM32H725RGV3 based board. I’ve inherited this board and as a result am not able to choose the microcontroller that exists on it. If it were up to me, I would’ve chosen a device from the STM32G4 range. Regardless, I ideally would like to use X-CUBE-MCSDK so I am not re-inventing the wheel, however, the closest boards are the NUCLEO-H745/55ZI-Q which is a dual core stm32h7 based board.Current reading topology: Three Shunt Resistors Control schemes required: FOC (torque control), speed and position control with absolute encoder.Comms interface: CANBus (expect to implement business logic myself)Modulation technique: Ideally SVPWM (is this the default)Motor: CustomWhat is the prescribed workflow for this application? Should I create a board based on the NUCLEO-H745/55ZI-Q and then attempt to modify the IOC to match my board? I was considering trying to use the example project “FOC STM32H745ZI with IH

Good morning,  I’m trying to build a project based on EVLSPIN32G0B2 evaluation board.I’m trying to establish a connection between the board and the STM32CubeProgrammer.Checking the electrical scheme, I saw that the USB connector on the evaluation board is connected to the port PB6 and PB7 (pins 45 and 46 of the SPIN32G0B2) which are the wires of an I2C port. Do I need any interface ?What’s the secret for a working connections ? ThanksStefano P.S. there’s another post on the same argument I wrote few days ago.I can’t delete it, can a moderator delete it for me ? It is useless. Thanks. 

This account only shares restored community content posted by members between May 22 and June 9, 2026, who did not register for the new community.Hello.I am creating a motor control project for the EVSPIN32G4 using MotorControl Workbench 6.4.1.The EVSPIN32G4 board definition provides configurations for "ThreeShunt_RawCurrents_SingleEnded_ExternalGain" and "ThreeShunt_RawCurrents_SingleEnded_InternalGain," but the current sensing section in the circuit diagram of this board appears to match the "ThreeShunt_RawCurrents_Differential_ExternalGain" configuration.However, adding this configuration causes MotorControl Workbench to fail with an error. This is likely because the definition for "ThreeShunt_RawCurrents_Differential_ExternalGain" does not exist for the STSPIN32G4 in "MC_SDK_6.4.1UtilitiesPC_SoftwareSTMCWBassetsConnectionParameters.json".1. Why is it that the EVSPIN32G4 schematic shows a differential configuration, but the board definition only provides a single-ended option?2. Is
