STM32 MCUs Motor control

Dear all, currently, I'm making to control a BLDC motor from throttle using ADC1 channel 0. The MCU part number is STM32G0B1RBT6. I can read the ADC value successfully in SDK 5.4.8. The way how I do is I defined the ADC1-IN0 in Cube Mx and then I added extra code in main.c then I can read the ADC value. Now, I want to switch the SDK to 6.2.1. but in SDK6.2.1 it's showing errors when I add extra codes in main.c. So, my question is how can i solve this issues in order to read the addition ADC in MCSDK 6.2.1.Below are the screenshots that I put the extra codes in main.c file. 

Hi,  I am having issues driving the STSPIN32G4 Motor controller with a custom PCB i made and am looking for help/Guidance with resolving the issue. Some background information: MCSDK Version 6.3.0Motor Pilot 6.3.0Custom PCB details: For our custom PCB we have the STSPIN32G4 and the MOSFETS on 2 different PCB's The image below shows the schematic for the STSPIN32g4 and the second schematic shows the schematic for the Hbridge The image below is a picture of my test setup. I have a breakout board connected to ribbon cables to transfer the signals from Board A to Board B. Details: I setup the project from STM workbench. I am currently attempting to run in speed mode (I will eventually try and run in position mode as well) and have tested the Generated code on the EVSPIN32G4 Eval board and runs fine. The modifications i made between the EVAL board and custom board are - Disabled the Push button- disabled the The temp sensor- Disabled the Over cur

Hi there, I'm trying to do a project that involves controlling a servo motor over the BLE I have a STM32wb15, i know my configuration is set up correct as I have copied a code from an example I have and the project works exactly as it should.My problem is the coding i have a very basic knowledge of programming(bit of a beginner) and what i need is to control a servo motor over a android app over Bluetooth using a slider to control the motor i have a very basic app set up which has a slider and a button-which is supposed to connect to the deviceSo if anyone is able to help that would be very much appreciated!

STEVAL-CTM015V1This evaluation board is a driver for the switched reluctance motor and comes with an MCU of STM32F3. Can I use other external MCU instead of this MCU(STM32F3)? If so, how?THANK YOU

I'm controlling a BLDC motor with an STM32F401 and am using TIM1 to generate the PWM waveforms to drive the motor and TIM2 in encoder mode to read the Hall encoder inputs from the motor.This setup is driving the motor well, but I'm setting a lot of variance on the timings from TIM2. I have TIM2 set up to capture a count into CC1 every time it sees a new edge (rising or falling) on any of the three Hall inputs. I'm then using this count to compute the spin rate of the motor in RPMs.To test this, I set up the motor running at 5000 RPM in open-loop mode (no changes to the PWM settings), and the unloaded motor is holding a very steady RPM as measured with an external laser tachometer. When I compute the rotation rate using the TIM2 CC1 count between Hall encoder edges, I get what looks like random noise between 4500 RPM and 5500 RPM, but when this is filtered, it's very close to 5000 RPM. See the plot below. The green trace is the raw RPM values computed from the TIM2 timer counts and the

Hello ST expert,I'd like to control 4 300W motors with the BLDC L6234 and my STM32F401, but the problem is that I can't use 12 TIMERS and 12 GPIOs just for that, I need to interface other modules.Can I just use PWM/BLDC, and interface the two like that?   STM32F401 L6234PD | | | PA6 (PWM) ----------> | EN1 (3) | PA6 (PWM) ----------> | EN2 (6) | PA6 (PWM) ----------> | EN3 (11) | PB0 ----------------> | IN1 (17) | PB1 ----------------> | IN2 (18) | PB2 ----------------> | IN3 (19) | | | | | 11V ----------------| VS (10) | | GND ---------------| GND (1, 2, 7, 16) ----+ | | | | OUT1 (4, 5) -------> Phase U of Motor | | OUT2 (8, 9) -------> Phase V of Motor | | OUT3 (14, 15) -----> Phase W of Motor   Best regard.

As stated in UM1052, chapter 14 there is often a requirement to control a BLDC motor control board over a serial connection. The above manual describes the protocol used by older MCSDKs. But the latest MCSDK 5.Y.x seems to use a slightly different procol called ASPEP.Unfortunately I could not find a documentation for that protocol on the ST web site.My question is: Is there any documentation of that new protocol or is it required to reverse engineer the STM source code to use it with an different application than the Motor Pilot?Thank you for any hints!Best Regards Thomas

Hi,Is there a sample code to control the STM32 motor board with UART from a host PCI'm mostly looking for setting and getting the encoder angles and speed control with the UART 

 Hello!We are currently using the STSPIN32G4 microcontroller for our project, which incorporates a quadrature encoder.In the start-up parameters, there are three key settings: Duration, Alignment Electrical Angle of Id, and Final Current Ramp value. We have determined the encoder alignment angle using the current waveform procedure.Could you explain how altering the default values of Duration and Final Current Ramp will affect the system? Specifically, we are interested in understanding how these changes might impact the displacement of the rotor shaft during the encoder alignment process, and whether setting a shorter duration could be disadvantageous.

Hello,I am trying to implement a P-controller-algorithm for two levers, where one lever follows the other one. The problem I have is that when the duty cycle of the PWM-signal reaches zero the PWM stops working if I change the position of the lever again. The signal is constantly high but doesn't give any current to the other lever even tough the PWM gets configured with a new duty cycle. The random thing is that the lever starts to follow again after pulling the other lever back and forth. I am wondering if there any issues with the configuration with the PWM signal on TIM1 or any other suggestions? The P-controller algorithm is in the StartADCTeleRegTask in the main file linked bellow.Any help is much appreciated! 

Hello! I am looking to run 4 industrial servo motors on any of the STM controllers (Any which can sustain such load, I am looking at STM32F7 series) in combination with TI DRV8323 BLDC motor driver. Now the issue here is these BLDC drivers require 6 PWM inputs to operate 3 half bridges (Just like any other BLDC driver) but with 4 motors it adds up to 24 PWM signals. I am confused if any of the STM can handle such extensive motor control application? Which one would be best suited for my application?Any help is appreciated.Stepper motor datasheet attached.

There is no documentation provided for the REV_PARK_ANGLE_COMPENSATION_FACTOR variable in the code.hElAngle += SPD_GetInstElSpeedDpp(speedHandle)*REV_PARK_ANGLE_COMPENSATION_FACTOR;What is the purpose of this variable? i searched in the documentation but no results turned up.

Hello. Trying to profile one of my engines with the ST Motor Pilot Tool (profiler) V1.2.9. Without any success.I have seen this warning in the STM32 Motor Control FAQ section.The STM32 MC motor profiler has the following limitation: it cannot profile motors with Rs < 1 Ω or Ls < 1 mH.If you still face problems, profile your motor manually using the following procedure.Since my engine met these characteristics.I have calculated the electrical parameters of the motor following this tutorial and also the tektronix application note (Capacitance and InductanceMeasurements Using an Oscilloscopeand a Function Generator).Now I would like to be able to use the engine profiler to obtain the mechanical parameters of the engine.Can it be done somehow with the profiler or can i calculate ir manually?Thank you so much.

Hello.I am using a Nucleo-F446RE board with the x-nucleo-ihm07m1 driver, to control a LA052-040E servomotor.Comment that I have not been able to generate the motor profile with the ST Motor Pilot Tool (profiler) V1.2.9.Which comes with the MotorControl Worbench 6.3.0 program,After connecting the device and clicking start, the connection is reset and the board is disconnected from the application.   But with the Motor Profiler 5.4.8 version. Yes, it generates the engine profile for me.Once the parameters have been entered, the position control application works, but I do not obtain all the desired power.The current consumed from the supply is 200mA and the motor supports up to 2.5A.I have the board configured for 1A as the maximum current. The driver supports 1.4A constat current.  How can I increase the power of the engine, I need it to have more strength. I think he is not giving his full potential. Thank you very much for your help and support.  

Our project uses an external ADC reference voltage of 3.03V.This value is properly set up inside the json I use to generate the inital project code ("amplifyingNetworkVm": 3.03, "polarizationOffset": 1.515).Now I found in the generated code that inside paramters_converison.h, the ADC_REFERENCE_VOLTAGE is set to 3.3V.Where am I supposed to set up the correct value so that it gets used by the code generator and stays when regenerating the project in CubeMX? Can I just manually set it?

Hello,For our application, we have developed a brushless motor driver 1.5KW based on the EVSPIN32G4 circuit board.We use a brushless drone motor with 14 pairs of poles (https://store.tmotor.com/goods-922-V605+KV210.html). I use MC workbench 6.2.1 for the application.After having profiled the motor and having found the best parameters for starting,I encountered a problem concerning the maximum speed of the application: The maximum speed of the application is set at 3200rpm and I cannot exceed 2300rpm.At this speed of 2300rpm I reach the maximum current per phase of 40A while I only consume 400W on my power supply. The phase voltage seems not to be sufficient, and I cannot resolve the problem. What parameter or functionality must be adjusted to increase the phase voltage ? Thanks for your help.Julien.

Hello everyone,I am currently working over stepper motor with STM32F7 series controller and i'm trying to control the stepper using PWM timers. Somehow there is no such support for the same as all i found is controlling servo motor or some other related searches. Main issue is i already created PWM and i can see it over Pins using oscilloscope but when i connect my motor it ain't move a bit, not even vibration which shows that nothing is happening through PWM. I would like to know about how to control motor using PWM. If anyone can help me from scratch that would be a great help.

After designing Motor controller, on what testcases we should test our Motor Controller?after going through internet and some theory, I found this:For torque:No Load Test Constant Load Test Max Load Test Negative Load TestRamp Load TestCyclic Load TestProgressive Load TestFor speed:Nominal Speed Test Max Speed TestAcceleration/ DeaccelerationI am new to it so if anyone working in this field can suggest more here or even any reference document, it would be grateful. Thanks

Hi, I'd like to use Run command for my stepper motor as follows. How can I set values in registers?Maximum speed: 4000step/sMinimum speed:  500step/s SPD: 1000step/sAccording to the data sheet, I can calculate the values for MAX_SPEED, MIN_SPPED and SPD in (Run command) as follows.MAX_SPEED:     4000 x tick / 2^(-18) =4000 x 250 x 10^(-9) / 2^(-18) = 262MIN_SPPED:       500 x tick / 2^(-24)  = 500 x 250 x 10^(-9) / 2^(-24)  = 2087SPD:                    1000 x tick / 2^(-28) = 1000 x 250 x 10^(-9) / 2^(-28) = 67108In the data sheet, Run command has Note section. According to the statement, MIN_SPPED <= SPD <= MAX_SPPED but my calculated values are MAX_SPEED < MIN_SPEED < SPD. Even though these settings, does motor rotate correctly?Note: The SPD value should be lower than MAX_SPEED and greater than MIN_SPEED otherwise the Run command is executed at MAX_SPEED or MIN_SPEED

Hello STM32 Community,I am currently working on a customized controller board with the same architecture as the EVSPIN32G4-dual, using the STSPIN32G4 and STDrive101, to control two BLDC motors. However, I have encountered a few issues and would appreciate any guidance or confirmation on the following points:2 Motor Configuration with 6-Step Algorithm: While setting up the MC Workbench, I noticed that I cannot select a 2 motor configuration when I choose the 6-step algorithm. Although I believe this might not be a significant issue, I would like to confirm if it is still possible to configure the PWM peripheral for the second motor manually? Any advice or steps to achieve this would be highly beneficial.Current Sensing with 6-Step Algorithm: Additionally, I found that the current sensing section is disabled in the MC Workbench when using the 6-step algorithm. I am interested in acquiring current readings with a single shunt configuration. Is there any possibility to enable or implement

Hi, I had successfully created a project using the AN5464 application note using the following hardware: NUCLEO-F303REX-NUCLEO-IHM08M1I have create the project using MotorControl Workbench 5.4.4 and managed to achieve rotation on the motor, however this doesn't seem to be a reliable code, it works for a while and then suddenly stops working, I have debugged the code and I have realised that it never goes beyond the "while(MC_GetAlignmentStatusMotor1()!=TC_ALIGNMENT_COMPLETED){}" eventhough it has worked for the past week! I have also noticed the motor doesn't take any current (0.01A) which means it doesn't even try to move if I don't power the microcontroller but only the ihm08m1 board it takes 0.04A when I plug in the microcontroller it goes down to 0.01A. Previously it was using 0.045A - 0.4A of current while driving the motor and 0.45A when in locked rotor mode. I cannot understand why did it suddenly stop?! I have checked the encoder and all 3 channels work fine. any help is much a

I'm working on a project with the EVALSTDRIVE101, and my motor has Hall sensors. I'm able to use the Hall sensors with SDK 6.2, but with SDK 6.3, the processor runs to the HardFault_Handler routine if the Hall sensors are enabled (as an auxiliary speed sensor).If the Hall sensor is enabled, the HT_Init function is called in the FOC_Init function in the mc_tasks_foc.c file. However, if I step into the function, a file opens indicating "Can't find a source file ... mp_hall_tuning.c." If I keep stepping through the disassembly, I eventually get to the fault routine. Something obviously broke in the new implementation.Can someone tell me where the mp_hall_tuning.c file is and why I don't have access to it? Is it included in a precompiled statically compiled library or something?

Hello, I am trying to use STM32 Motor Control Workbench(which I downloaded from the material of Motor control part 5 package) to control a BLDC motor with FOC. The motor I have is a custom one, the control board and power board are going to be custom one, but for now, I want to use STM32F401-RE NUCLEO BOARD as a control board for testing and evaluation. After setting all the motor parameters, the shunt resistor values and all the conditions and startup ramps and so on, I want to generate code to see what I am going to upload on the microcontroller, and here I have my first problem. When I click on generate, as you see below, I can choose as firmware package version the reccomended one(1.22.0), the one that I have installed (1.28.0) or the latest one Whichever version I choose, there is the reqest to setup an internet connection, even for the one on my PC If I click on yes, then I'm stuck on this other window, with this error if I click on check connection If I decide for a NO, then

I am working with ctm010v1 got this communication error, Any documents available for communicate the eval-board with pc.
