STM32 MCUs Motor control

Hi,I'm using Motor Control Workbench 6.3.0 to create an application project (STM32G431 with IHM16M1 motor drive).Motor Control Workbench 6.3.0 creates a folder, Src, which has a lot of motor control related .c files. Here are my questions:are there any reference documents for these .c files (mc_api.c, mc_task.c, mc_tasks_foc.c, etc.)?What's the control flow, execution sequence, and/or call tree for the motor control project created by Motor Control Workbench?Any input is appreciated.Thanks

Hi all, I have been trying to control my BLDC motor with an condition where if the surrounding temperature increases a threshold temperature the bldc motor should turn fast else slow. I am using lm35 as temperature sensor, i was able to interface this using stm32 nucleo g431rb board , esc and lm35 but i want to interface this through the code generated from motor control workbench. I need few insights on this, the code is generated for P-Nucleo-IHM03 motor control pack with FOC control algorithm.

Hello! I'm trying to configure the following setup to run the motor profiler in order to characterize a set of small/low-power BLDC motors. Configuration:I'm using MCWB 6.21Control board: Nucleo F401RE in the following configuration:JP5 at U5V,JP1 OFF,JP6 ON.Powerstage IHM17M1:JP6 and JP5 are bridged (shorted),JP3 and JP4 are both bridged/shorted from "middle pin to 3sh."To make sure that the profiler works at all, I am trying to use the Bull Running BR2804-1700kv when configuring the project in the MCWB and start by profiling that motor. The resulting project is very similar to the one generated by the pre-configured package IHM002. After checking the "motor profiler" under application configuration and generating the code, I get very strange behavior from the Motor Profiler.Problematic Behaviour:After pressing "start profiling," D13 and D11 on IHM17M1 light up continuously while D12 is off for. The LED's dips in intensity before turning off completely - and then nothing else hap

 Hi Everyone,How can we determine if the computational power of only one STM32G473xx MCU is sufficient for controlling two PMSM motors? System clock is 168 MHz.However, is a good estimation technique available? Motor commutation will be based on field-oriented control, FOC. The Hall signals will be captured using the advanced timers 1 and 8.

Cannot Remap Pins My design (custom PCB) is based on the B-G431B-ESC1. I'm trying to swap the V and W PWM channels. I cloned the B-G431B-ESC1 board and just swapped the pin definitions for the V and W high and low channels. No errors during generation or build. However, the motor doesn't turn and the CubeMX IOC file has those four pins locked (purple) in reset state. This issue existed in V6.2.1 and I hoped it would be resolved in V6.3.0 but nope. My CubeMX is fully up to date (6.11.1) and I'm using FW 1.5.2 (recommended). Frustratingly, I can't even choose to swap V and W channels on the current sense side, because I later get an error saying it's not compatible with the FOC algorithm.  

I'm working with the STEVAL-SPIN3201 boardI have compiled and uploaded example "6s_STEVAL3201_HS_VM"I have a 70mm diameter sensored BLDC motorWhen I connect through the software ST Motor Pilot V0.9.9 click in "Start" Motor and the motor turns 1/4 turn and stops . I get a "FAULT_NOW" error message "Software Error" . In Logs "[ERROR] - MotorControlProtocol: ASPEP_RESP ERROR:CMD_NOK"I use ST "MCSDK 5.Y.3" version. 

Just like, we can monitor current, speed waveforms in Motor Pilot of P-NUCLEO-IHM03, can we somehow see Torque waveform in it as well? Or by any other means to monitor torque performance? 

The P-NUCLEO-IHM03 with type selected as "FOC" has the firmware pre-installed. After pushing Blue start/stop button, the motor starts but fails to continue. In Motor pilot, it is showing that a fault is thrown (startup failure) and the motor shuts down. The P-NUCLEO-IHM03 Black button needs to be pressed to clear the fault, but the motor still does not continue to run upon Blue button start. Control Board: NUCLEO-G431RB  Power Board: X-NUCLEO-IHM16M1Motor: Gimbal GBM2804H-100T    

How to read/write PWM Register in P-NUCLEO-IHM03 - Kit ? It is associated with TIM1 having 4 channels. My motor is running for few seconds and then stop (which by default according to the documentation should be running continuously), that's why I am trying to figure out if PWM Registers are storing current values. In debug mode, SFRs section, I found TIM1, but it has several components, which one corresponds to storing current value?Please suggest.Thanks in Advance!

Hi, I have an issue with ST Motor Pilot. I can't connect my board, it doesn't recognize my board and my motor. I tried different baudrates but it doesn't change anything.I verified the connector (USB A - micro USB) and it doesn't change anything. I'm using the MC_FOC_SDK library. Could you please help me ? 

Hello,i am trying to run the Evalkit-Robot-1 example project. unfortunately i get the error "configuration files cannot be found in 'MCSDK_v5.4.4/MotorControl'. This version is no longer available for download. Is there an updated version of the example project somewhere that uses a newer sdk? 

How to use in main.c the user button of B-G431B-ESC1 board ?I want to togle the position each time I press (amd release) the button.Waiting for target position completed and than I can press the button again.I have selected the PC10 pin in MXCube that originate this code in main.c: /*Configure GPIO pin : PC10 */GPIO_InitStruct.Pin = GPIO_PIN_10;GPIO_InitStruct.Mode = GPIO_MODE_INPUT;GPIO_InitStruct.Pull = GPIO_NOPULL;HAL_GPIO_Init(GPIOC, &GPIO_InitStruct); in main I write this code, but nothing happen.Where is the problem ? if ( GPIO_PIN_10 == 0 ){while (GPIO_PIN_10 == 0){}Pos = MC_GetCurrentPosition1();if ( Pos == 0.0 )Pos = 314.159;elsePos = 0.0;MC_ProgramPositionCommandMotor1(Pos,1.5);while ( MC_GetCurrentPosition1() != Pos ){}}    

I am using 3 Channels to generate 6 pwm using complementary pwm by timer 1. I want to release outputs of CH1 and CH1N when modulation is low (ie. PWM near 50%), and do the same for other channels (shifted 120degrees in time).I try playing with register CCER :TIM1->CCER &= TIM1_OC1_DISABLE;  // using  #define TIM1_OC1_DISABLE ((uint16_t)0xFFFE)and later :TIM1->CCER |= TIM1_OC1_ENABLE;   // using #define TIM1_OC1_ENABLE ((uint16_t)0x0001)Disabling works fine, but re-enabling is done with approx 10ms delay for some reasons when I need a few tens of us max delay.. (PWM is at 30kHz, center aligned)..Using MOE bits works fine, but does skip outputs on all channels simultaneously.Any idea ? Thks, Pierre

Currently I am implementing a 6 step algorithm in Steval-spin3202 with A2212 13T 1000 kV motor. While starting the motor with motor pilot I am getting an overcurrent fault. Please give me suggestion how to overcome this error.  

Hey everyone!I was just exploring different features of the ST MCSDK and encountered the on-the-fly startup option dedicated to fan application.Whenever I check this option, after the startup procedure, the motor accelerates to its nominal speed and then the firmware somehow takes control and run the closed loop to control the speed.I tried to eliminate this behavior and changed a lot of parameters including speed PI coefficients and it didn't workIs this behavior normal or am I missing something?Has anyone had the same problem? Could you please guide me if you have any idea?Thanks a lot!

When STM32G431 is used for motor control, the left alignment cannot be selected after oversampling is enabled, but the program will report an error when it is changed to right alignment. May I ask why? 

I am testing the Standby mode with the EVSPIN32G4 board. However, it is not entering standby mode. When I check the Vcc voltage, it outputs 8V despite being set to standby mode. Have you checked if a functional test for standby mode has been conducted? Please check if there is an error with the STSPIN32G4 chip itself. STSPIN32G4_init(&HdlSTSPING4);STSPIN32G4_reset(&HdlSTSPING4);STSPIN32G4_clearFaults(&HdlSTSPING4);STSPIN32G4_standby(&HdlSTSPING4, true); 

Hi, I have managed to get my ipm motor running with hall sensors. I can run the motor with motor pilot no problem. I can run the motor down to zero rpm and in reverse direction. I have it running with a pwm signal generated on an arduino in forward rotation. The code generated by MC Workbench only allows for forward rotation. Can anyone tell if it is actually possible to get the motor to run in forward and reverse with a pwm signal.

MCWB Version: 6.2.1CubeMX Version: 6.10.0Issue: I generate a default project for the B-G431-ESC1. Only settings I change is to enable the FreeRTOS with TIM6 as the tick timer. Firmware Package Version is V1.5.1 (Recommended).Via CubeMX I add a GPIO output pin for debug purposes and regenerate the project. FreeRTOS settings show that TICK_RATE_HZ is set to 1000 (1ms).I open the project with CubeIDE and add HAL code to toggle the added debug Pin inside the HAL_TIM_PeriodElapsedCallback for TIM6. My expectation is that the pin now toggles at an 1ms interval. When looking at the pin's signal, I see that this is the case, as expected.I now create a custom task inside CubeMX. The default code adds osDelay(1) which translates to 1ms. I move the code to toggle the pin to this custom task. My expectation is that the pin should again toggle at an 1ms interval.However, when checking the pin's signal, the pin toggles at a 500µs interval.When double-checking the code, I noticed that the default cod

New P-NUCLEO-IHM03 purchased from Mouser does not work right out of the box. The P-NUCLEO-IHM03 has the firmware pre-installed. After pushing Blue start/stop button, the motor starts but fails to continue.Connecting to X-CUBE-MCSDK, the SDK shows that a fault is thrown and the motor shuts down. The P-NUCLEO-IHM03 Black button needs to be pressed to clear the fault, but the motor still does not continue to run upon Blue button start.This is not the behavior described in the getting started, or the videos about the P-NUCLEO-IHM03 or the X-CUBE-MCSDK.Re-programming with the P-NUCLEO-IHM03 with the example project does not fix the fault.I do not believe the P-NUCLEO-IHM03 should behave this way. Do I have a bad one? Should I get a new one?

For our application, we are running the stepper motor from 5 step/sec to 6500 step/sec and to achieve this step/sec we have kept the FS_SPD register value to 2333.33 step/sec. There is a switching between micro-stepping and full step mode at 2333.33 step/sec. Using a script, we are changing steps/sec from 1800 step/sec to 2400 step/sec and from 2400 step/sec to 1800 step/sec. I have attached a video for the same. We found that the motor is continuously stalled during this range. The stepper motor is running smoothly for all other ranges. is it related to the powerSTEP01 driver FS_SPD register issue? Can you provide a solution to resolve this issue? @Cristiana SCARAMEL @Douglas MILLER 

Dear STM32 Community,I am reaching out to you regarding a specific inquiry about the development of a prototype that involves controlling BLDC motors using an EVSPIN32G4 demo board. Our aim is to set up a test stand where the motor speed control is commanded from a Windows PC. The control software, written in C, is intended to send the speed values to the EVSPIN32G4 demo board, similar to the functionality of your Motor Pilot Software.Our main question concerns the communication between the PC and the demo board. Your documentation describes the "Asymmetric Serial Packet Exchange Protocol" for UART communication. Is there a library or software toolkit specifically developed for implementing this protocol in our PC software? We are looking for a solution that facilitates seamless and efficient communication between our PC-based control software and the EVSPIN32G4 demo board.We would greatly appreciate your support in determining whether there are existing software libraries or examples

Dear Team,I am using the STM32F103C8T6 MCU and I am trying to generate PWM signals with dead band.and according to my configuration dead band is not in sync.Please let me know what configuration I have to make?  Note: I have gate driver which Lin is INVERTED so, that's why I am generating this type of PWM [ you can say complimentary ][ I have attach the c file ]Best and regards,Dipak 

How can i add multiple charts to the dashboard? I want to use at least 2-charts in the dashboard, and monitor some variables (not an array) on a chart while some other variables (not an array) on a different chart. I have seen one chart + gauge(s) examples a lot. But all I need is to use two or more charts in the dashboard.
