STM32 MCUs Motor control

In the STSPIN32G0601 device, the stm32g031 controller core has internal connections to complementary gate drivers. The outputs from the stm32g031 that can be configured with alternate function complementary signals (PA7, 8, 9, 10, PB0 and 1) are not used though.  Internal connections in the STSPIN32G0601 are PA8, 9, 10, PB13, 14, and 15.  I need to program a 3-wire, 2-phase signal that has a pulse frequency of 3,840Hz.  I can do this with 3 separate output compare interrupts with each interrupt service routine writing to 2 pins.  This is cumbersome compared to using the timer peripheral's PWM capabilities which are not available due to internal signal wiring.  I have found nothing in the MCSDK development software that addresses this; so, I am coding in STM32CubeIDE.  MY QUESTION IS:  am I overlooking a simpler way to approach this?

Hello,I am running a BLDC motor in sensorless mode using Nucleo-F101RE with the X-Nucleo-IHM16M1 board. The motor starts successfully when I press the Start button from the Motor Pilot GUI.However, I am facing the following issues:When I suddenly increase the speed to high RPM, I get a speed feedback fault.When I suddenly decrease the speed, I also get a speed feedback fault.Sometimes I also encounter an overvoltage fault during these speed changes.Any guidance on how to resolve or tune the parameters properly would be very helpful.Thank youBest RegardsRahul

Hello,I’m testing a motor with integrated Hall sensors for which I don’t have the datasheet and that I can’t disassemble. From the tests I’ve done, it appears to be a 4-pole motor with Hall sensors spaced 120 mechanical degrees apart.I first tested the motor in voltage mode without using the Hall sensors: it runs smoothly, doesn’t overheat, and spins correctly, so the pole count seems right. Then, I moved jumpers 5, 6, and 7 to connect the Hall signals to the microcontroller, powered them at 5 V with jumper 3, and checked the H1, H2, H3 sequence with an oscilloscope. The signals are present and in sequence.However, when I try to start the motor, it needs a manual push to get going and then it immediately ramps up to maximum speed. Also, I don’t see any speed feedback on the Motor Pilot, and I can’t change the target speed. If I try enabling polling of HALL_SPEED or HALL_EL_ANGLE from the registers, I get the following log error:[WARNING] - MotorControlRegistersBank: Accessing register

Hi everyone,I'm working with the STM32F446RE and exploring the 6-step BLDC motor control example provided by the STM32 Motor Control SDK. In the CubeMX configuration of the firmware:3 GPIOs are configured as analog inputs:M1_BEMF_U → PC3 → ADC1_IN13M1_BEMF_V → PA7 → ADC1_IN7M1_BEMF_W → PB0 → ADC1_IN8However, in the ADC Injected Conversion Mode, only Channel 13 (PC3) is selected and used (1 injected conversion configured).See image below for reference:My question is:Why are all 3 BEMF pins configured in CubeMX if only Channel 13 is used in the ADC injected group?I expected that all 3 channels would be used in the injected sequence to sample U, V, and W BEMF voltages.Do they dynamically change the injected channel in code depending on the commutation step? Or is there another reason for this configuration?Thanks in advance for any clarification!

Hello，I am using MCSDK6.4.0 on STM32G431CBT6 for motor drive development.The generated code runs without any modifications. When using the Motor Pilot tool to start the motor,the chip crash, and there is no change in the motor. Debugging reveals that the program randomly enters NMI_Handler,HardFault_Handler, and FMAC_IRQHandler when starting the motor (after entering FMAC_IRQHandler several times during the first programming run,it does not enter again). I am using STMCubeMX 6.3.0. The chip's power supply is measured to be normal, and no reset has occurred.Below is a screenshot of the interrupt entry. What is the cause of this issue, and how can it be resolved.

Hello,Here are a few things I need to clarify regarding the EVSPIN32G4 current measurement and the related MCSDK software:Referring to section 5.6.1, 5.6.2 and 5.6.3 of the UM2850, I believe that the topology using three standalone OpAmps presented in section 5.6.2 is not currently supported by MCSDK, is this correct?So, considering the 2 topologies presented in 5.6.1 and 5.6.3, is there a major disadvantage to go for the internal PGA solution compared to the first configuration which requires external feedback networks on the inverting side of the OpAmp?At the end of section 5.6.3, it is recommended to connect the inverting input of the PGAs to shunt resistors to perform differential current measurement in case of high current application, but I don't have the possibility to do it in MCSDK since only the "single ended" sensing type is available, what do you propose in this case?Thanks in advance and best regards.

Can you provide the calculation formul"Shortened in accordance with the posting guidelines.I have an EVSPIN32G4 evaluation board with a sampling resistor of 0.005Ω.Why does a current of 40A correspond to a threshold of 7427 (0.37V)?

Hey STM community,I have a G431RB & IHM16M1 however whenever i try to run the motor pilot, i cant seem to connect to the board. I  have made sure all the necessary link drivers are installed, i have made the baudrate  115200, 8bit all to match up with the software but i consistently get no connection. My cube ide, motor workbench and motor pilot are all up to date and i have the associated packages( the G4 library v1.61) installed in cube-mx.Thanks 

Hi everyone,My evaluaiton bord is STVAL-SPIN3201 and I am using Motor Control Workbench 6.4.1.First of all I work with Motor Control Workbench , after work CubeMx program and generate code and finally open CubeIde but I did not see Core folder. I dont know how can write my motor control program in main().c .When open "C:\Users\eem_o\.st_workbench\projects\STEVAL_SPIN3201 " folder "Inc" and "Src" folder in this area.When try to transfer at STM32CubeIde folder "Inc" and "Src" folders, given to many error.How can solve this issue?  

Hello Everybody,Here are the software and boards in this case:1. MC workbench 6.3.22. NUCLEO-F401RE3. X-NUCLEO-IHM08M1I try to use the boards to obtain motor parameters. Now I got the result as illustrated in the picture? Should I set the parameter "placement electrical angle" to 131? Thank you!

Hi, Dear STM motor control experts:   I am conducting experiments on the BLDC HSO project, and during project testing, the code in the SPD_init() function runs to IMPEDCORR_setParams(pHandle->pImpedCorr, &ImpedCorr_params_M1); No problem, but run the function IMPEDCORR_setRs_si(pHandle->pImpedCorr, flashParams->motor.rs); A hardware failure occurred, and the code jumps to HardFault.Handler(). Because the function is in a lib file, it cannot be analyzed. Please help analyze the cause.Thanks!Best regards.

We have a design on an ST32G431 based on the B-G431B-ESC eval board that we are trying to migrate to an STSPIN32G4. However the tools appear to not let us set up the same 3-shunt, internal op-amp, internal PGA, differential configuration on STSPIN. There seems to be a problem with the 3rd op-amp and supporting differential mode.All works fine with the B-G431B-ESC based design but if I create a board based on STSPIN the workbench generates errors.RCSConnect: ThreeShunt_RawCurrents_Differential_InternalGain Global NO OPAMP for Phase VWe see the same errors if we load the EVLSPIN32G4-ACT board in the workbench and hit "go to summary". The difference with the EVL board is that it has a number of different variants so will still load but doesn't offer the "3-shunt + differential" option even though it is in the board config file.The pins appear to be available and as far as we understand it the STSPIN is based on the same ST32G431 die so if it works on a ST32G431 it should work on an STSPIN

Hello and good day. I am doing a project of running a motor using 6-Step with Hall Sensor.I am facing an Overcurrent issue while using Motor Pilot V6.4 in 6-Step + Hall Sensor mode. In MC Workbench, the current limit is set to 15A but the Nominal Current is shown as 2.16A in the Motor Pilot GUI. No matter what I do in MC Workbench, the Nominal Current doesn't change and always shows as 2.16A. Consequently, I can't start the motor as it there is always Over Current fault as the motor needs more than 2.16 to start.I know that it's not a limitation of my Power Board as it is rated at 20A. In MC Workbench, it's clearly stated 15 Apk is set and is within specification of Power Board.The strange this is, when I try FOC + Hall Sensor mode, this doesn't happen and the Motor Pilot GUI is showing the correct Nominal Current limit (15A) below. Somehow, this issue only happens in 6-Step + Hall Sensor mode.May I know why this Nominal Current setting is different between FOC

Hello,I encountered an error when using MCSDK 6.4.1 (Motor Control Software Development Kit 6.4.1) to configure the STM32G431VBT for using the three-resistor internal operational amplifier and performing external differential gain sampling. I would like to ask how to resolve this issue.The following images show my configuration process： 

I am using stm32g431c8u6 microcontroller . I have enabled timer 2 channel 3 for alternative pin of PB10 and I have enabled channel 4 for PA3 pin. I set counter perioud 499 and prescaler value =0.When I plug the debugger and run the code only channel 4 generate PWM signal and channel 3 does not generate PWM signal.I am using DRV8845 motor drive to control 2 motors. It has two direction pins t control two motors. Below I linked the MCU pin configuration.This is my code to move forward the 2 motors.HAL_GPIO_WritePin(GPIOA,GPIO_PIN_2,0);HAL_GPIO_WritePin(GPIOB,GPIO_PIN_10,1); HAL_GPIO_WritePin(GPIOB,GPIO_PIN_0,1);HAL_GPIO_WritePin(GPIOA,GPIO_PIN_7,1);TIM2->CCR3 = 400; //out_pid;TIM2->CCR4 = 400;//out_pid; Please guide me to how to enable PWM signals for both channels. Thank you. 

I have installed MCSDK 6.4.1I can run the workbench (MotorControl Workbench_6.4.1) without any problem.But i cannot run the Motor pilot application.At first there was an error stating "The code execution cannot proceed because MSVCP140.dll was not found Reinstalling the program may fix this problem"I then installed "Microsoft Visual c++ 2015-2022 Redistributable (x64) 14.44.35211This error is not present anymore but nothing is starting when clicking on the motor pilot icon, no new window appears.

Hi, I am trying to use the disco-B-G431B-ESC1 board to move my gimbal motor. I am using the simpleFOC library example. The problem I am facing is that the motor is not moving. The motor is vibrating at a pole. If I move the motor by force then it vibrates at the next pole but does not start to rotate. I have checked with different motors but the issue persists. I have tried this same code with other gimbal controllers and it works fine. The motors are not faulty as I have tested them. Could anyone please advise me what to do?Below is the code I am using to run the motor at constant velocity in open loop mode - // Open loop motor control example #include <SimpleFOC.h> // BLDC motor & driver instance // BLDCMotor motor = BLDCMotor(pole pair number); BLDCMotor motor = BLDCMotor(7); // BLDCDriver3PWM driver = BLDCDriver3PWM(pwmA, pwmB, pwmC, Enable(optional)); BLDCDriver3PWM driver = BLDCDriver3PWM(PA8, PA9, PA10); // Stepper motor & driver instance //StepperMoto
