STM32 MCUs Motor control

This might be the most banal question you've heard all day. I don't know if it's even possible, but I thought there is the option of switching between the two. I'm using hall sensors for my application, so it probably doesn't matter much either way.Would any kind soul help me out? Any advice is appreciated (especially screenshots of where to find stuff within the latest MotorControl Workbench V5)I'm using a B-G431B-ESC1, by the way.

Hi. I'm getting fault after fault trying to get my motor to run. FAQ document says to change ramp-up parameters. Why? Why should I specify any current values? I want the motor to get to a certain speed, and the control algorithm should handle the MOSFET switching and PWM to meet my target speed and be able to adjust it to a dynamic load, right? The FAQ pdf says the ramp should end at 30% of max speed and then 15%?  I'm using a B-G431B-ESC1 and a 14-pole, 1500KV, 2-4S, 30A, sensorless BLDC.Would some kind soul please enlighten me?

Hello.I'm using Nucleo F446re and IHM07M to control a BLDC motor. It has a built-in 2000 pulse quadrature encoder. The MCSDK version is 5.4.8. I tried the position control method and it works fine. However, it only allows me to control the motor based on the provided angle in radian. For a specific purpose, I need to control the motor based on the number of counts it crossed. Is there a way to do that?Regards, Sihab

My motor is rated at 24V volts but the motor control software gives over voltage errors above 21-22V. There seems to be some logic which scales against the ADC reference voltage and generates over voltage errors at around 22V. I suspect there is distributed logic at play here as setting the motor parameters to 24V makes no difference to the sensing. What do I need to change to allow a board supply of 24V?According to calculations based on info in the user manual, increasing the supply will not push anything over 3.3V (there is plenty of room for scaling up) and damage the board.

Hi, I'm trying to control a BLDC motor via a B-G431B-ESC1 and an Arduino Mega. The Mega will be the master and send commands to the board. For ease of use, I'd like if it these were strings. I have found examples of how to use UART in an STM32 application, except here the DMA UART initialization is done by ST MotorControl and ST MX, so I don't know if there are implications. The initialization has all of the below in it, so it seems DMA is disabled. MX_USART2_UART_Init(); ... sConfig.DAC_DMADoubleDataMode = DISABLE; ... hadc1.Init.DMAContinuousRequests = DISABLE; ... hadc2.Init.DMAContinuousRequests = DISABLE;Furthermore, I don't see an interrupt being declared anywhere for UART, there's just this: /* Initialize interrupts */ MX_NVIC_Init(); /* USER CODE BEGIN 2 */Very frustrating. Would greatly appreciate some help, I feel like this is something that is done in 10 lines of code.Thank you in advance, kind soul.

Hello!We have STEVAL-SPIN3201 board and we need to drive RS PRO 536-6030 motor.Also we built motor control application using Motor control workbench software.After loading the application in the board we are not able to spin the motor.The motor tries to start but short after it stops in sensorless mode.With HAL sensors it even doesn't try to start.Would you please help!

I've got STeval-CTM010V1 board, with the help of MotorControl Workbench source code is generated. The issue is that on evalboard there is LQFP64 package but code is generated to LQFP100 one - I didn't manage to obtain code which fit the evalboard package LQFP64.What I've done:MotorControl Workbench 5.4.8:- Updating button: uC is changed to STM32F303RB but code is generated to different package- Generating button: Error "unable to generate ioc file due to: When calling function "name", required parameter "gpio_port" (parameter#1) was specified, but had null/missing value.."CubeIDE 1.11.2:- In project settings -> MCU Settings is not possible to change microcontrollerMigration:- According to UM1718 exporting current project configuration to a compatible MCU causes that uC in package LQFP64 is not foundHow prepare project to correct package?

I'm trying to create an esc for a drone using the B-G431B-ESC1. Our project requires that we use open source firmware so I'm using the STMCW firmware, and the motor profiler tool. I am comparing results to another ST-based esc that runs BLHeli firmware and another which runs SimonK firmware which are common and trusted ESC firmwares for drones.I've profiled the motor with the propeller off which didn't work well at all. The motor wasn't able to start with the prop on due to the change in the mechanical model. I again profiled the motor with the prop on, and it works well up until a PWM input of 1750us, at which point the motor appears to stutter and de-sync, presumably throwing the esc into a fault state at which point the throttle must be lowered below the arming threshold for a short time, then raised again to restart the motor. Without the propeller on, the motor easily operates throughout the full range of the pwm input. I disabled all protection circuitry to verify that there wasn

Hello @allThe following problem hunts me since some weeks: I use a custom motor control PCB based on STM32G431CBU. Communication via UART works great through motor pilot but as soon as I start the motor, the comunication is gone and I cant stop the motor for a couple seconds. There are several error messages on the bottom, ASPEP PACKET UNKNOWN" , or sometimes:and sometimes a CRC error...On tart of the motor pilot when connecting to COM port, there are several errors indicated, one of them:The NVIC priority is already set HAL_NVIC_SetPriority(DMA1_Channel2_IRQn, 3, 0); by default. Baudrate is 1843200.I tried using USB isolator , using a notebook with battery and without power supply, to see whether its caused by noise from the ground. Nothing changed.When I dont log any parameters like phase current A, B, communication is a bit better. But as soon as I want to log data, the traffic seems too high to handle and communication breaks down.Help is very much appreciated.

We are trying to evaluate the EVSPIN32F0602S1 motor driver. I've found I should use the 6 step driver firmware project EVALSTSPIN32F0H60 for this, but it turns out by default only IAR and Keil uVision are supported which we don't have. We work with STM32CubeIDE.Since it does come with a IOC file I figured it should be no problem to generated project files for STM32CubeIDE, but somehow this doesn't work when I try it from the MX tool in the IDE. It generates only a small part of the required files.So I tried it also directly from the STM32CubeMX tool, where it does appear to generate all required directories and files. However, I needed to configure all include paths manually to resolve compile issues.After some time solving compile errors by adding include paths, I stranded in os_tick_gtim.c (CMSIS/RTOS2) where it tries to include RTEComponents.h, which doesn't exist. On the next line it tries: #include CMSIS_device_header, which should probably be defined in RTE_Components.h

Why? CCER CC4E is almost always enabled after motor stop. R3_2_SwitchOffPWM() is usually executed between TIM UP IRQ and ADC_IRQ at medium freq task. In R3_2_SwitchOffPWM(), Timer MOE is set to 0 then ADC_IRQ is not triggered and PWM OFF while CCER CC4E keeps enabled at the last TIM UP IRQ.CC4 output signal trigger ADC and its IRQHandler (high freq task).High freq task changes each PWM output value of CH1, CH2, CH3 , which are not

A customer implemented the “EVALSTDRIVE601�? evaluation kit with a NUCLEO-G431 board.This board combination does not exist in the "Motor Control Workbench" : the "EVALSTDRIVE601" evaluation board is not listed.The customer started his evaluation with a "NUCLEO-G431RB" combination and a "STEVAL-IPM05F" power card, the source code of the STEVAL-IPM05F has been adapted to be compatible with the "EVALSTDRIVE601" card.Unfortunately, it is not possible to customize the following points in the tool on the “Current Sensing�? configuration page :• “Shunt Resistor�?•" Gain "In addition, the regulation management parameters of the various feedback loops seem to depend on the power evaluation card selected.With the configuration mentioned above, he can use the “Motor Pilot�? tool but the motor is about to starts but never spin.The customer suspects a misconfiguration of the parameters.For the moment, he is blocked at a few configurations with evaluation boards and so he is asking : 1.

Hello, I want to flash a FW to my STSPIN32G4 custom boards that tests each phase FET individually by switching through the different high- and lowside FETs one per one. Is there an easy way to do this? Any help is appreciated.PS:All I found is a function to turn on all lowsidefets:  For the highside switches I know its more complicated because the bootstrap caps first need to be charged. I also found this init function:All I need is a code snippet to change the output state of those 6 pins from low to high and vice versa. Thanks! :)

I am using the latest motor control workbench (6.1.0) and the CubeMx (6.6.1). The motor control code generation is working if all the files copied to the project folder. If I select the "Copy only the necessary library files" some header files will missing during compilation. See picture below. The "Add necessary library files as reference in the toolchain project configuration file" also fails. It does not reference the motor control lib files at all. I have the motor control lib and the HAL lib in the right folder in my PC.Our workflow based on the "references" method, and it is a problem now to get it work easily.Do you have any solution for this?

I have created ioc project using MCSDK 6.1 for steval-spin3201 board to control a BLDC motor in sensorless PLL mode and/or HALL sensor mode. I have used ST Cube MX to generate Cube IDE project files , build them and downloaded executable files to the board. I have used ST Pilot program to communicate with the board . I was able to start and stop the motor but I could not make the motor run at the speed that I have set. Motor actual speed oscillates in a very wide range around the value that I have specified. It seems to me , speed regulation ( closed loop operation) does not work .

Setting the current reference is describes as:void MC_​SetCurrentReferenceMotor1(Curr_Components Iqdref);What should I type to replace Curr_Components and Iqdref?I want to manually set current reference to increase torque when the​ motor is in low rotation speed. Is it possible?

My application will manage multiple power sources (battery, DC, UCPD) and have a TCPP01-M12 protecting CCx lines. With this configuration the STM32G4 could already be powered by DC or battery, but must be able to negotiate 20V on VBUS. I want to avoid having the MCU do any voltage sensing on VBUS or having logic to turn off TCPP01-M12 protection. I also want to make sure USB protection is active regardless of MCU state.DB/ will be pull high by Power management (this is to detect actual dead battery or no power). VCC will be pulled high by LDO from VBUS which means TCPP01-M12 showed dead battery and VBUS 5V was provided.Since there is already 5V on VBUS at this point do I also need to show dead battery at MCU in order for negotiation for 20V to happen? (Assuming the MCU is already powered or VBUS turns MCU on via power management)If so, what is the correct way to connect UCPD1_DBCCx pins? The documentation says they need to be shorted to UCPD1_CCx pins, but the diagram shows connected t
