STM32 MCUs Motor control

STM32F103C8T6 MCU is used for controlling a brushless DC Motor. Firstly I used bipolar switching for Inverter Circuit. TIM1_CH1 ,CH2 ,CH3 pins used for upper mosfets of each leg and TIM1_CH1N,CH2N,CH3N used for lower mosfets. When I want to set the pwm frequency at 18kHz , One of the legs (CH1 and CH1N - Phase A) both upper and lower mosfets aren't working (MCU doesn't create pwm signals) and when i decrease the frequency to 10.2kHz then MCU creates pwm signals on these pins but not same frequency with other Pins (CH2 , CH3 , CH2N , CH3N).after start-up procedure pwms signals are set in interrupt.a example of IT codes;case GPIO_PIN_0:if(HAL_GPIO_ReadPin(GPIOB,GPIO_PIN_0))  {        HAL_TIM_PWM_Stop(&htim1,TIM_CHANNEL_2);         HAL_TIMEx_PWMN_Stop(&htim1,TIM_CHANNEL_2);         HAL_TIMEx_PWMN_Stop(&htim1,TIM_CHANNEL_3);    &

I have a motor running in the V1.1.3 Motor Pilot.Now what?I built a 6step controller of a hi-revving, low inductance/resistance motor. It compiled in STM32CubeIDE and is pushed to the board.I started the motor pilot and successfully connected to the board.Made a couple of updates to the input a table of ramp up values - see image. Then monitor bemf (on the graph) and start the motor. It runs for several seconds before indicating "start-up failure"Is there some documentation about how to tune the app and motor?  Also how do I manipulate the graphs? I notice if I use more buffers I can capture more details but can not zoom it.

A very simple example of this is Register 0x16 Which is STEP_MODE register. It says Bits 3 and 7 are always 1. I write 0xCC to the 8 bit-register. When I read it, it reads as 0x4CWrite Param is just the ADDRESS sent. Read Param bit 5 is set to 1. So 0x16 becomes 0x36 to read register 0x16. To make sure it is not my software, (I am using HAL) I have the logic analyzer output attached.  The SCK frequency is 4.1 MHz, it must be less than 5.0 MHzThe shortest CS high is 915 ns, it must be greater than 800 ns. So, I do not believe it is timing related. What am I missing?

In this post, it was mentioned that the Sequencer is recommended to avoid race conditions especially when entering low power mode. Are there any specific examples of race conditions and how the sequencer avoids it?On the other hand, in AN5289, the document doesn't mention race conditions but rather that sequencer avoids event loss during low power modes. So, is the statement about race conditions even correct?My main goal is to understand how the sequencer really improves things since it's forcing us to write code to work with this framework. In addition, my project will require several motor control loops and I'm concerned about how the sequencer may affect the timing of my control loops.

The "documentation" suggests that any IO port that can act as an interrupt is usable, but the motor control workbench only has selections for A2, A9 and B10, all of which are used for other peripherals. The document suggests selecting a "dummy" port and then manually editing the .IOC file afterwards (!?!) but none of the available ports are listed.

I have connected various stepper motors to multiple x-nucleo-ihm01a1 shields on a NUCLEO F466RE.The code is the same as ST's X-CUBE-SPN1 (i just changed the function names) In main() after SPI has been initiliazited at 2MHz at mode 3, I set the registers to their init settings ( begin() ) then attempt to move the motor forward 16000 steps.L6474 myL6474;   int32_t pos; uint16_t mySpeed;   //----- Init /* Start the library to use 1 shield */ /* The L6474 registers are set with the predefined values */ /* from file l6474_target_config.h*/ myL6474.Begin(1); chThdSleepMilliseconds(500);   // /* Move shield 0 of 16000 steps in the FORWARD direction*/ myL6474.Move(0, FORWARD, 16000); // See whats happening in status register after move command myL6474.GetStatus(0);   // /* Wait for the motor of shield 0 ends moving */ myL6474.WaitWhileActive(0);    The SPI communication is working as the waveforms show the right commands (commands in hex on the right

What is the difference between modes Enabled, Six-Step, and Induction in STM32CubeMX?Documentation is lacking

Custom board with STM32G474QE and MCSDK 5.Y.4Hi, we have a 5 pole pair PMSM which is running at 800VDC consuming ~36Amps at 1800rpm during testing in water. We run it in speed mode, which results in a Torque Ref of >21400 read in MotorPilot(~72Amps) where the limit is 100Amps. The motor can run at this speed for quite some time, but is not intended to do so for very long.The problem occurs when we increment the speed only by 50-100rpm more, the motor speeds up and reaches the desired speed. Shortly after, we hit overcurrent and the motor shuts down properly. If we inspect the HighFrequencyPlot looking at Ia and Ib, we can see that something is happening right before the currents reach IQMAX . (see the second to last waveform, inside the circle) If we lower the VBUS to e.g. 600V, 550V or 500V, the same thing happens but at a lower rpm and Torque Ref. Can anyone help me identify what could be the issue here?

The attached ioc file causes STM32CubeIde to throw a nullptr excp.It was generated by doing the following:Open motor control wb 6.1.0Follow the wizard to enter a v low inductance/resistance motor.Select the B-G431B-ESC1 boardGenerate the projectSTM32CubeMX opens"Generate Code"Open STM32CubeIdeIt opens and throws a NullPtrExcpPlease could someone at ST fix this defect?

Is there any chance that STM32CUBEIDE will have support for STEVAL-ESC002V1?If not - what is the fastest way to do development for this eval board using the IDE?Generally - as a new user of STM products, the overall impression I get is once of chaos. There is an over abundance of hardware but confusion about what are the mainstream strategic products. The software support seems patchy - some products, which I am guessing are the strategic solutions are in STM32CUBEIDE, others are not.Trying to figure this out is expensive, slow and frustrating. I just want a simple BLDC motor controller! What is the fastest, simplest way to make this happen?

I just bought a NUCLEO-F104RE and the X-NUCLEO-IHM01A1.The main problem is have is where to put the en.x-cube-spn1 files. The instructions in Section 3.3 need to be a little clearer and more specific. Also there is no .ioc file in the software. Do you build a default (in my case) Nucleo-F401RE board project then start over writing files from the files in en.x-cube-spn1? It does not say. The compiled help files like X-CUBE-SPN1-HELP.chm does not work right. I can see the contents, but no text under the contents. Please just give a .pdf of the detailed information and screw the help file.  Paragraph 3.3.1.1 Where do the files from the BSP folder go? Do you create a BSP folder in the project? Where? Under Drivers? Or under Core? Or does the .h files go into the /Core/Inc and the .h files go under /Core/Src? Or somewhere else?Paragraph 3.3.1.2 First paragraph talks about MotorControl/motorcontrol.c/h files. I searched the entire directory structure and could not find motorcontrol.c or

I'm using an STM32F429. I'm doing a motor control application.I enable a lot of timers at startup in my application.But during runtime when the application receives a command it enables a timer capture through DMA on TIM8. This is when there is a small pause when it calls HAL_TIM_IC_Start_DMA(). This disturbs other interrupts that seem to pause temporarilly.These are my timers I enable at startup: // Start timers HAL_TIM_Base_Start(&htim1); HAL_TIM_IC_Start_IT(&htim2, TIM_CHANNEL_1); HAL_TIM_IC_Start_IT(&htim2, TIM_CHANNEL_2); HAL_TIM_PWM_Start(&htim3, TIM_CHANNEL_1); HAL_TIM_IC_Start_DMA(&htim5, TIM_CHANNEL_4, countCapture, ARRAY_SIZE(countCapture)); HAL_TIM_IC_Start_IT(&htim5, TIM_CHANNEL_1); HAL_TIM_Base_Start_IT(&htim6);My call to HAL_TIM_IC_Start_DMA() during runtime. This is when other interrupts are disturbed.HAL_TIM_IC_Start_DMA(&htim8, TIM_CHANNEL_1, (uint32_t *)countCaptureWholeTurn, ARRAY_SIZE(countCaptureWholeTurn));Why does it pause o

I had IDE 1.10.1 and a Nucleo-G431RB board. We created a 6 step project using motor control Workbench, Motor Pilot and the project would build successfully. The IDE updated to Windows 1.11.0 and the project would no longer build. The builders list was empty.Reinstalling 1.11.1 had no effect. Recreating the project from motor control workbench had no effect (I didn't expect it to - I assume this an IDE config issue, but I wanted to try it).I could not find a way to restore the builder list. I am new to this platform.Reinstalling the old version 1.10.1 after renaming the ST folder which was not empty has reinstated the builders list and I can build again. My project was present in the IDE without me having to import it, much to my surprise.How do I successfully upgrade to the latest version?

Hello, Why the NUCLEO-F446RE board isn't available in MotorControl Workbench 6.0.0?It was available in MotorControl Workbench 5.4.8.For motor control the recommendation is to use the STM32G microcontrollers?Thanks for your support!

Hi,We are planning to develop a motor driver application with stm32g051c6 micro controller. While searching, we couldn't find an EVK board with the same MCU. We have found some alternative EVK boards(NUCLEO-G031K8, NUCLEO-G070RB, NUCLEO-G071RB, NUCLEO-G0B1RE). But the controllers in those have either more flash and RAM size. We would like to know whether any EVK boards are available with "STM32G051C6" micro controller. Please support asap.

Below is a copy of a warning found within the PID-controller of MC-SDK 5.Y.4.We have a Cortext-M4 based board so I guess the warning text is a copy-paste and I should not care that it mentions Cortex-M3.. /* WARNING: the below instruction is not MISRA compliant, user should verify that Cortex-M3 assembly instruction ASR (arithmetic shift right) is used by the compiler to perform the shifts (instead of LSR logical shift right)*/ //cstat !MISRAC2012-Rule-1.3_n !ATH-shift-neg !MISRAC2012-Rule-10.1_R6How can we check if the compiler uses ASR and not LSR in these situations?

I use ST motor control SDK 6.0.0. Why is the checkbox "Use encoder alignment" not active? All required options for encoder are set.
