FYI, I have installed a complete set of your software tools for BLDC control (equivalent to the set used in your hands-on workshops in prior years) on my Windows 10 system, and the subset of these tools that are available on my Mac Big Sur system. But now:How am I notified when new releases are available?It doesn't appear that the apps themselves check for updates when started or provide "Check for Updates" commands. Wish they would.I've searched your website in vain for a collected list of tools, current releases by platform, release dates and download links.Your online ST MC Suite tool appears to be useful for initial installation, but a very blunt instrument for maintaining a developer's installation over time or even finding out when updates are available.A related item is documentation. As I've requested before, I would like to get an update to the MasterPresentationMotorControlSeminars2018_v0830.pdf presentation that was used in one of your hands-on workshops in the US three year

I'm running a 6 pole pair low inductance BLDC motor with a STM32G431 MCU and STSPIN233 driver (5V). It starts successfully 96% of the time ramping to 1850rpm in 4-5s and running at constant speed. However, 4 time in 100 it will just slightly budge then stop. However, no error is reported.Using MCSDK it will show the speed ramping up to 1865rpm and no faults are reported. The registers report control mode 1 and status 6. The code thinks the motor is running.I also get the same result consistently when performing a locked rotor test.Any ideas why no errors are reported?My start up ramp applies a healthy current at 0 speed for 1000msec then applies a healthy current for 4500ms in PHASE2_DURATION. The observer is enabled starting at PHASE2. The code is set to look for 5 consecutive good readings (NB_CONSECUTIVE_TESTS) and the reliability limits are set to 15 and 17.

I have generated the code from ST motor control workbench for Keil -5 IDE. But it's not generating (.uvmpw) extension file. It's generating only (.uvprojx) extension file that is also not opening with Keil IDE. Its giving an error (Can not read RTE data from project file: RTE is not enabled).please can you help me to generate (.uvmpw) extension file to debug and download the code in STEVAL SPIN3201 hardware. Or share any documentation or video for generating the c code for Keil IDE to flash the code in STEVAL SPIN 3201 board.

Similar kind of project is generated when the main sensor is Observer+PLL and auxiliary sensor as Hall Sensor. Now tried Hall sensor as main sensor, but error exists when building a project.

I am using a B-G431B- ES1 hardware but when opening the motor pilot i am getting error : Port Open.Also checked the COM port and it is correct ,even updated the drivers as well

Hi,So I presently have this problem. As seen in the picture, my timer1 time base is set to 1919 and it has a 48MHz clock source, which means I should produce signals with frequency of 25kHz. But this is not the case. instead the output signals from the timer is about 1.2kHz.What could possibly be wrong? How is it possible that the timebase is set to 1919 for a 48MHz clock source and it doesnt produce the right 25kHz frequency?

Dear all, if the answer at my above question is:"YES" and the available space is already full...does is there a compatible chip with larger memory? or did I make some mistake? any suggestions?See below pict for better understandingCristiano

Hi, I am using NUCLEO-F303RE, I have purchased a power board (IPM evaluation board EVALM13645ATOBO1) from Digikey.In the Motor control workbench, I didn't find above mentioned power board part no. so, can you tell me, which one I need to select in the drop-down list of power board custom board or else?In current sensing & Bus voltage sensing, the below-shown circuit value, Is automatically calculated? or Is the user needs to configure this value? If yes, where or how to find/check these values?  3. is it possible to change the board details once it is selected. 

I plan to implement velocity measurements for a BLDC motor with Halls A/B/C using the timer XOR as described in the STM32F411 Reference Manual RM0383, Section 12.3.18. The below graph is from Figure 39 on page 244. The red-lines are mine. Note that the signal TI1 includes the XOR'ed Hall A/B/C signals. However, the Hall A is needed for motor commutation. Question: I also need the individual Hall signals for other reasons, including Hall A. Can the STM32F411 configured for this, although that is not obvious from the figure? Or is it necessary to implement the connection from TIMx_CH1 to TIMx_CH4 as shown by the red-lines? Thank you for your feedback.

MC Workbench is not configuring OPAMP3 but PB0, PB1 and PB2 are configured for OPAMP3 inputs and output in eval board . 

I configure 6 channel GPIO pins to generate PWM signals to control 3-phase bridge. There is one pin(PC13) sometimes stop to generate signal. Even we reset 3.3V power voltage, it won't recover. one time I inject 20k square wave to pin PC13 to verify other chip， but it cause the processor recovered. I use pin PA7 to sampling voltage(use as internal op-amp ）, it always has 1V even turn off 3.3V power. I am guessing because of this voltage cause the processor can't reset completely? How to explain these？ ​Thanks，​

I saw a problem posted 2 years ago similar to my problem now but the issue was closed with a ticket filed and I can't access any follow ups. Start-up failure, MC_START_UP fault flag getting set sometimes. Posted on April 12, 2018 at 23:49Using the MCSDK 5.4.5, I can startup and run a BLDC motor most of the time. About 10% of the time, I get a Start-up failure and in the code I'm running it hits a breakpoint when RUC_Exec returns false causing a failure. I have modified values in the start up ramp table (current, time and speed) but haven't found a suitable result. The motor appears to be spinning up smoothly without any audible noise but then stops with the MC_START_UP fault.I haven't found the source code for RUC_Exec. I'd like to know what condition is causing the failure so I know where to fix my code.

Hi All,Can someone please enlighten me on this:Why is the integrator term, and the control function output scaled and shifted as shown in this code below?Why would I need to do that in an embedded system such as STM32?

I used STSPIN32F0A as my motor control chip, the X_CUBE_MC workbench version is 5.4.4 , and the firmware package version is ST32 FW v1.11.2, then I generate the code ,but when I connect the MC workbench , I couldn't connect the MC workbench serial , and gave the below fault ， This problem has been bothering me for a long time，Thank you very much for helping me 

Hi, I had been using the older version of MCW w/ Monitor to use an STEVAL-ESC001V1.I got a new 30Pole BLDC to test out. Since the board does not support Hall Sensors I had hacked some test points and pads to pull out leads, re-configure the "Digital I/O" to use Hall Sensors. It works fine, has been working for other motors too.:thumbs_up: I used this board (STEVAL-ESC001V1) to save a Profile of the Motor using ST Motor Profiler.I then switched connectors to my connect to my new EVSPIN32F02Q1S1 and upgraded to MCSDK_v5.Y.2 which has ST Motor Pilot.I noticed that I still cannot use EVSPIN32F02Q1S1 to Profile the motor as it's not available on the ST Motor Profiler.At first I had it configured for using Hall Sensors. The code generation was smooth.At first I got error that PWM frequency was too high (default 30,000 Hz (EVSPIN32F251) )I reduced it to 16KHzThe ST Motor Pilot connected smoothly and was a displaying real time speed of the rotor.Trial 1: The motor failed to start with "FOC Dur

I have a strenge problem. I can run the Motor Profiler 5.4.7The program generates the profile and I can use the play function to control my motor. Great.then I export the profileGenerate code using ST Motor Control Workbench 5.4.7. I dont make changes, Open the code in STM32CubeIDE 1.7.0, compiles okay and uploads.When I try to control the motor using ST Motor Control Workbench monitor, the motor makes a very tiny click and over current fault is activated. I can not make the motor move regardless what I do. I have played with acceleration etc without luck.I can do the same procedure with another totally different BLDC motor and make it run and control it using the ST Motor Control Workbench monitor.If I for testing purpose connect the first BLDC motor, that I could not control, to the ESC, using the motor profile from my working test using another motor. I can make the motor run a bit, after 2 seconds i get a speed feedback error of cause because I have the wrong motor connected, but t

Hi ​Sensorless BLDC can't run very well at low speed，I would like to know which STM32 series or which ST motor control workbench version can support HFI，and if support，can it run sensorless bldc motor well at low speed？Or none of them can support HFI，and all bad at low speed，​Thanks very much，​

Hello,I have some B-G431B-ESC1 boards that I would like to control using CAN. Is there a working example code somewhere? I cant seem to find anything in this forum. In ST Motor Control Wokbench I can only setup normal serial communication.I hope someone can help

Hello,I am using the STEVAL-SPIN3201 to drive a motor with sensored FOC.Inside the code, I use the syntax of the FOC library to program how the motor should move.I created the project in mc workbench (find the project file attached).Then I imported it into STM32 IDE and added the following code section inside the main file (user code 3): MC_ProgramSpeedRampMotor1(1000/6,0);     MC_StartMotor1();     HAL_Delay(8000);     MC_StopMotor1();     HAL_Delay(500);  MC_ProgramSpeedRampMotor1(-100/6,0);    MC_StartMotor1();    HAL_Delay(7000);    MC_StopMotor1();    HAL_Delay(400); /* USER CODE END 3 */When I test the program, the motor moves first to one direction for 8 seconds, then to the other direction for 7 seconds (as it should do). However, the speed is always the same (according to the moto

Hi, I am Using Nucleo F446RE and IHM08M1 boards for motor control(24V DC-link). When Motor starts accelerating from 1000 to 3000rpm (step response), the tracking is good and when decelerating from 3000 to 1000rpm (step response), an under voltage fault occurs and motor stops. Need help to solve this issue?Thanks in Advance. Regards,Vijay Ganisetti

My code reads the motor state and faults after a start-up to ensure the motor is running correctly. I've been using MC_GetCurrentFaultsMotor1() for motor faults but it NEVER reports other than zero. I've primarily been using motor state and speed to determine if a fault occurred.For example I may read FAULT_NOW (10) or FAULT_OVER (11) but the procedure noted always reports 0. Is there a procedure that reports the most recent fault, even if it has already been cleared?Thkx

Hello there,I've been messing around with a development board I've recently bought, STEVAL-SPIN3204, and I've been attempting to produce a RPM measurement using one hall effect sensor input attached to the PA5 pin, which with can be set to TIM2_Channel1. Using STM32CubeIDE.I've been following many examples that I've found online on how to set up Timer Input Capture interrupt and time and time again it didn't seem to be working out for me. I'm still new to STM32 programming but following examples I learn quite a lot, although I'm stuck on this one problem I cannot seem to go over. Here's some attachments that I feel should go along with this question.Code Snip of input capture callback:/* USER CODE BEGIN 4 */   void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim) { if (htim->Channel == HAL_TIM_ACTIVE_CHANNEL_1) // if interrput source is channel 1 { if (Is_First_Captured==0) // is the first value captured ? { IC_Value1 = HAL_TIM_ReadCapturedValue(htim, TIM_CHANNEL_1)

thank you.
