Hello,I configured the RCC in STM32CubeMX, but the generated Keil code doesn't contain the SystemClock_Config function. Can anyone help me solve this problem? The device model is STM32H7R7L8H6H.Thanks in advance.  

Hello,I have a STM32F407G-DISC1 (a blue one, do not know if that matters), that I am using to prototype a system where I communicate via CAN bus to a boost recuperation machine, however I am not able to see my messages on the osciloscope, I am able to receive the messages from the machine, which clearly is sending messages when I check with the scope and the readings are coherent.// Inclui os cabeçalhos necessários #include "app.h" #include "CAN.h" #include "DBC.h" // Define macros para verificar o estado da ignição e do pedal de freio #define IgnOn HAL_GPIO_ReadPin(GPIOE, IgnSwt_Pin) == GPIO_PIN_SET // Ign ligado #define Braking HAL_GPIO_ReadPin(GPIOA, BrkState_Pin) == GPIO_PIN_RESET // Freio pressionado (ativo em nível baixo) //extern ADC_HandleTypeDef hadc1; // Handler do ADC usado para ler o pedal extern CAN_HandleTypeDef hcan1; // Handler do barramento CAN1 extern CAN_HandleTypeDef hcan2; // Handler do barramento CAN2 (comentado) extern uint8_t Pt_Edrv_Des_1[8]; // Buffer da m

Hi everyone, I wanted to know if semihosting is available on N6 or not as I am trying to enable it following the below tutorial. https://community.st.com/t5/stm32-mcus/how-to-use-semihosting-with-stm32cubeide-and-stm32/ta-p/49742 but I am getting the following error.

hi I'm using nucleo-h755 144 pin board, i have configured for the project, now I'm changing the mcu from stm32h745BITx 208 pin package. is there any option in stm32cubeide to import the configuration from one mcu to another mcu in cube ide without or with opening new project. since i have configured almost 142 pins in h755 nucleo board, i don't want to do it again for the 208-pin package.i have checked in cube ide list pinout compatible mcu option is not coming for this series, previously i have used g4 series for that it is showing.so it possible to import the nucleo h755 pin configuration to stm32h745BITx 208- pin package in cube ide or not.please suggest some ideas, since it will reduce the some time.   regards,Srinath

Describe the SetupDevice: STM32WB55CGU6Tool: STM32CubeProgrammerDescribe the IssueWhen attempting to flash the BLE stack version 1.23.0 to the STM32WB55CGU6 using STM32CubeProgrammer, I encountered issues with the following firmware files:stm32wb5x_BLE_Stack_full_extended_fw.binstm32wb5x_BLE_Stack_full_fw.binstm32wb5x_BLE_Stack_light_fw.binThe version information is not displayed in the “Selected File” section of STM32CubeProgrammer. After flashing, the FUS reports version v0.0.0.0, indicating that the firmware may be invalid or improperly formatted. This makes it impossible to proceed with BLE stack initialization or further development.I would greatly appreciate any clarification on whether these binaries are compatible with the STM32WB55CGU6 and, if not, whether a corrected version of the BLE stack 1.23.0 can be provided.Additionally, since I’m unable to downgrade the firmware on my device, I would like to kindly ask if it’s possible to release version 1.24.0 of the BLE stack ahead

Hi : I want to know which MCU support BC1.2, how can I use CubeMX to filter these MCU? 

Hi  I use stm32f412 vet6.Flash size is 512kbye.But stm utility program is 1mbyte size. Why??

The issue is that after downloading the modelzoo pose estimation example code from  https://github.com/STMicroelectronics/stm32ai-modelzoo-services/tree/main/application_code/pose_estimation/STM32N6/Model/STM32N6570-DK for N6 board in the STM32N6570-DK and using cubeprogrammer to load the .hex file using the external loader and erasing and programming tab, it says everything has been done correctly and the application is starting. However on the board nothing happens. Is there a way to fix this? I tried originally with the dev mode set to 1 using the boot0/1 switches and also pressing the reset/user buttons and switching from dev mode, but nothing happens. I even tried to do full erase of the chip to get rid of the preinstalled intro application and still it seems to flash correctly, but does not do anything. I tried to build the .hex file using STM32CubeIDE 1.19.0 and that hasnt worked either (it worked, but nothing happens on the board - e.g. LCD is dark). I

Hello,I’ve configured SPI in CubeMX with DataSize = 12 bits. However, when I use the HAL function HAL_SPI_Transmit, the pData argument seems to require a uint16_t (or at least 16-bit aligned) buffer.I'm a bit confused about how this works in practice. Since I'm sending a 16-bit word, but only configured 12-bit frames, does the SPI peripheral transmit just the lower 12 bits of each word? Or do I need to pack the 12-bit values differently?I'm still fairly new to STM32 development, so I appreciate any clarification you can offer!Best regards,Kewin

I am trying to connect the STM32L475E-IOT01A board to Azure IoT Hub using the inbuilt Wi-Fi module, and I'm working within STM32CubeIDE.I found the official example project iot-middleware-freertos-samples, but it uses CMake, while I need a similar example implemented directly in STM32CubeIDE.I have already configured the Wi-Fi module in CubeMX, but I need help understanding:Which libraries are required to add manually in STM32CubeIDEHow to port or adapt the CMake-based example into an STM32CubeIDE projectAny guidance, example projects, or documentation would be greatly appreciated.

Hi everyone,I'm working on programming the B-U585I-IOT02A board for my Master's thesis in Computer Engineering. My goal is to continuously record audio samples using the onboard microphone, then convert them into spectrograms and analyze them using AI. Unfortunately, I'm having trouble setting up the microphone. I can't find any reference projects online for audio recording on this board, and I'm currently stuck. My original plan was to use DMA with its callbacks (HalfTransfer, TransferComplete), but I'm not sure how to properly configure the microphone or which peripheral I should use to capture the audio: MDF1, ADF1, or SAI1? How do I then link DMA to one of these peripherals to trigger the appropriate callbacks? Which pins should I enable in the .ioc file, and in which mode, to make everything work correctly? Any suggestions or references to similar projects would be greatly appreciated. Thanks in advance!

Hi I'm trying to reset the stm h563 to factory settings because I do some test before and I would like to use the stm for other things but I can't reset the changes I made with CubeProgrammer. I have those errors....   

Hello,I'm using STM32CubeProgrammer v2.17.0 with Linux (Linux Mint 21.3). There are a some bugs/improvements I discovered:1. By default, USB DFU devices are not recognized by STM32CubeProgrammer in user mode due to a permissions issue. To resolve this, I manually added an udev rule to allow access to USB DFU devices without requiring root permissions. It's unclear why this isn't the default configuration, especially since udev rules for STLink devices are automatically set up during the installation process.My udev rule (new file in /etc/udev/rules.d/) Spoiler (Highlight to read)# stm32 dfu mode, give access for STM32 cube programmerSUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", \MODE="660", GROUP="plugdev", TAG+="uaccess"# stm32 dfu mode, give access for STM32 cube programmerSUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", \MODE="660", GROUP="plugdev", TAG+="uaccess" 2. It seems that the UI isn't displayed correctly for USB DFU mod

Hello,I have an existing project and I'm attempting to retrofit it with TrustZone, starting with a new IOC file that will be the basis of the project which I will then retrofit my code into. I'm starting with a clean slate ioc file for the STM32U545CET6 from CubeMX. Is there a way to enable TrustZone with all memory 'whitelisted' such that all accesses are allowed? If so, please provide details such that the firmware will operate (initially) as if TrustZone were not there. I either want to:1. Make everything in the processor secured (such that I have zero access errors) and get my firmware running. Selectively mark certain parts of my application unsecured one-by-one to ensure I don't break anything too badly.2.

Hi,I am quite new to using CubeIDE. I compiled and ran my first program and the below is the response from the IDE:>>>>>>>>Erasing memory corresponding to segment 0:Erasing internal memory sectors [0 6]Download in Progress:  File download completeTime elapsed during download operation: 00:00:00.587   Verifying...    Time elapsed during verifying operation: 00:00:00.048  Download verified successfully   Target is not responding, retrying...Shutting down...Target is not responding, retrying...Target is not responding, retrying...Target is not responding, retrying...Target is not responding, retrying... <<<<<<<<< This seems to me that the program was properly downloaded to the board and then verified. Why is it then reporting that the target is not responding? Regards 

Hi,   My CubeIDE 1.18.0 was working fine for many weeks with Nucleo-H753ZI board and CubeMX.   Two days ago, it stopped working after I upgraded it to version 1.19.0. The screen stayed in IDE home window.  Then   1, I deleted directories below      C:\ST\STM32CubeIDE_1.19.0       C:\Users\User\STM32CubeIDE       C:\Users\User\.eclipse        C:\STM32\Workspace   2, I Installed STM32CubeIDE 1.18.0 as administrator.   However, the project can't be built. I found -  1. Window → Preferences → C/C++ → Build → Environment list is empty.  2. .C:\Users\User\.eclipse is missing.- was not regenerated.   I repeated the above steps to install 1.19.0 as administrator. The result is the same.   1. Window → Preferences → C/C++ → Build → Environment list is empty.  2. .C:\Users\User\.eclipse is missing.- was not generated.Thank you very mu

Are there any plans to upgrade STM32CubeIDE to include support for C23?It would be nice to have as it brings things like constexpr in, which makes the use of constants much better as they are subject to compiler checking and can call (constexpr) functions.

Hello,I need guidance to create a very simple AI project using CubeIDE (CubeMX) and Neural-ART runtime. I can use all the example projects successfully but failed to create one from scratch till now. I faced no challenge earlier when using H7 for my AI projects.I am using STM32N6570-DK. I tried using different ways, but I either got strange compilation/linking errors or got stuck in the neverending "Generating code" screen.Anyway, my latest attempt is as follows:Create a new FSBL project by selecting my DKChose not to initialize default peripheralsSelected X-CUBE-AI 10.0 core and template application from the Middleware sectionSelected a MobileNetV2-based tflite model and Neural-ART runtime.Analyzed using "n6-allmems-O3" and generated code.

I am fairly new to programming. So I have STM32CUBEide at work and at home. If find it extrodnarilly difficult to work on something at the office and then take it home or in reverse. I have tried exporting, importing, importing from the file system and just copying files directly. Each time only after several hours I stumble upon getting the project working and I have to do it all over aging when I go back to the office.  And really irritating is that it looks like its going to work, when your importing an archive and just as you go to select the location. The darn window is gray out.  And when the IDE finally does work it is not obvious why. Despirite for help!!!

Hello ST Community,I'm working on an STM32 project where I use TIM1 Input Capture + DMA to log timestamps of Hall sensor edges (motor feedback) on TIM1_CH1 (PA8). The captured values (CCR1) are stored in a circular DMA buffer.I have a 1ms PID interrupt, where I:- Poll the DMA buffer to process new timestamps- Calculate motor speed- Generate precise PWM signalsSo, I do not want DMA interrupts, because I manually poll the buffer in the PID loop.---Problem I'm Facing:I'm also running CAN communication in this project.When the Hall sensor edge interrupts were enabled, they sometimes delayed or blocked CAN transmissions, especially when the motor is running at high speeds.That’s why I switched to DMA-based Input Capture, so the Hall sensor events are logged with zero CPU overhead and no interrupt latency, which also helps ensure smooth and timely CAN transmission.However, Cube MX automatically enables the DMA interrupt for TIM1_CH1 capture, and I don't want tha

Hi Team,I'm currently transitioning from using UART interrupt with timeout to DMA-based reception on an STM32G4 controller. I’d like to implement a similar behavior where I can detect the end of a UART message using idle line detection while receiving data via DMA.Is there a recommended way to combine DMA reception with UART idle timeout on STM32G4? Specifically:Are there any best practices or example configurations for this setup?

I download the latest firmware package "stm32cubeh5-v1-5-0.zip" for STM32H5, from ST's website. I followed following instructions to install it via STM32CubeMX:Open STM32CubeMX.  Go to Help > Manage embedded software packages.  Choose the desired STM32Cube MCU Package for your specific series (e.g., STM32CubeL4 for STM32L4 series).  Click "Install" or "From Local" if you have a downloaded archive.  The firmware and examples will be installed in the STM32Cube repository, usually under C:\Users\<your_username>\STM32Cube\Repository.  I get following failure message, at the very end of the installation process:I checked the Repository directory, The previous version - "STM32Cube_FW_H5_V1.3.0" is installed. Should I uninstall the V1.3.0 first, before I can install V1.5.0?Any helps? Thanks!
