STM32 MCUs Software development tools

I created a new project using CubeMX, and after that I plan to implement a framework for my firmware. I would like to better understand the best way to organize a clean and maintainable folder structure.A colleague told me that all folders should be created inside the Core directory. I would like to understand whether using Core to contain my framework is the best approach, or if it is acceptable to create additional source folders outside of it.Additionally, where can I find examples of STM32 firmware projects generated using CubeMX?

Ports definition in main.h forced to include too mutch in dependend source files when one needs ports definition only.More convenient dedicated header file with ports definition only. Something like ports.h.It would be nice to have more layered structure.

Hello ST Community,I would like to report a potential discrepancy I have discovered between the pin definitions in STM32CubeMX and the official datasheet for the STM32N6 series, specifically concerning the Serial Wire Output (SWO) signal used for debugging (SWV/ITM). This issue led to a hardware design error on my part, and I believe it warrants clarification to prevent others from encountering the same problem.According to the STM32N647xx datasheet (and related family documents), the SWO function is assigned to Pin PB5, The TRACECLK function is assigned to Pin PB3However, within STM32CubeMX (I am using version 6.16.1)(N6 MCU package version 1.3.0), the graphical pinout view shows that Pin PB3 is also listed with the "DEBUG-JTDO-SWO" functionality. More importantly, when configuring the debug port in the "SYS" settings (e.g., selecting "Trace Asynchronous Sw"), the software automatically assigns the SWO signal to PB3.Trusting the configuration tool, I proceeded to design my PCB wi

do the example of LPGPIO,why show this error.Getting started with LPBAM - stm32mcu 

I have just spoken with an ST sidekick, and I was informed that STM32CubeMX is currently not supported on Windows ARM64.Thank you for the clarification.  

I recently updated my stm32cubeide from 19 to 20.0.0 but the .ioc files of my existing projects open as text file not graphical as before. How to fix it to work as before? PS: I mistakenly chose VS-code target and it's not possible to delete the post and repost. I use STM32CubeIDE on Windows and my issue have nothing to do with vs-code (I don't use it whatsoever)   

Hello everyone,I already asked similar question but I got no sensible answer yet. I am trying to implement the Custom HID drivers in the STM32UG7VJT microcontroller, in standalone mode, so no RTOS. The only thing that I can find from STM32 is this example https://github.com/STMicroelectronics/stm32-usbx-examples/blob/main/Projects/STM32H743I-EVAL/Applications/USBX/Ux_Device_CustomHID that uses the RTOS. I am trying to remove the RTOS from it but until now I didn't even manage to get the descriptors right. The device is enumerated but not recognized. So does anyone have any idea on how to make this work? I already looked at all the tutorials available, they don't fit my case, all of them are based on the H7 family which seems to have different architecture for the USB.  Thank you in advance

I've tried this evening to download STM32CubeIDE on 2 different accounts, 2 different computers, a phone, and have reset my computer and also deleted my cookies but still will not download. Nothing happens after I accept the terms and conditions. I have also tried to download as a guest the link from the email still just takes me to the download page but it won't download.

Hi everyone,this is my first post, as I have always been able to solve my problems thanks to your help. Unfortunately, I can't find a solution regarding the CubeProgrammer API, which I am currently working on. I am developing an update tool that will use the internal bootloader of a STM32H743. For this, I am developing a C++ programm, using Visual Studio 2026 Version 18.2.0 with .Net Framework Version: 4.8.09221. CubeProgrammer_API.h and all neccessary .dll files are included as described in the documentation. There are no compiler errors or warnings. I used the attached UART example for testing but it is not possible to connect to my device. COM ports are detected by getUsartList function as expected. If I try to connect with function connectUsartBootloader as shown in the example I will get error -5 ( CUBEPROGRAMMER_ERROR_NOT_SUPPORTED ). Nevertheless, it is possible to establish a connection and execute a file upload with STMCubeProgrammer GUI and also with STMCu

I have a characteristic that supports write and indicate. A command is written to the char, the server responds by indicating the characteristic to the client. I'm using Stm32CubeMonitor-RF 2.19.0 to test the server, but indications always cause a ACI_GATT_PROC_TIMEOUT_EVENT because STM32CubeMonitor-RF does not issue a ACI_GATT_CONFIRM_INDICATION after an indication is received. log file attached. 

After installing under STM32Cube key actions, and all other headings, "There is no data provider registered that can provide view data." is displayed. I have tried adding the path to Cube MX. In the STM32Cube Core plugin, runtime status shows not yet activated. Manually activating does not work. Running on Windows 11 arm64.If I roll back to a version 2, everything seems to function, however I need version 3 working. Any suggestions?

Question moved from this post. Hi @mƎALLEm ,I am using STMCubeIDE with cubeMX, in that there is no such configuration for VREFBUF. is there any alternative way for that?

0I have a device with an MCU in DFU-mode, and I want to flash new firmware to it. To do that I have the software we have developed at my company to interact with the device, mainly a Wpf-application written in C# and Xaml, which in turn uses the KSociety SharpCubeProgrammer library to make calls to the STM32 CubeProgrammer_API.If I use the STLink V3 SET hardware over I2C I get a CubeprogrammerErrorWriteMem error (return value -10), i.e. a memory write error, but using the same firmware file but instead directly over USB, i.e. not using the STLink, I get no error and the firmware is updated. In either way the calling code is almost identical, and I have checked that the data and address is the same when calling the API over both I2C and USB. The method called from the API is in either way WriteMemoryAndVerify(...).I found some information saying that it's the STM32_Programmer_CLI.exe that does the actual reflashing. If that's the case I have a vague idea that I must use the parameter --

Hi,if I connect the Cubeprogrammer via jlink to the custom board (STM32H562) and want to reset the option bytes by menu-selection "Reset MCU to factory settings", the process don't finish because the mentioned error pops-up.Is this caused due to a missing signal on the debug connector? The problem is now, that the mcu is in provisioning state and I want set it back to open state.Kindly regards,Stefan

On a Nucleo-H563ZI with CubeIDE 1.14.0 and firmware package for H5 1.1.1.I managed to get SPI transmit and receive using DMA, triggered by a timer, going not using linked lists. I get my requested number of transmissions and results into my buffers as witnessed on an oscilloscope and a live watchpoint.But when I enable circular mode, no other modifications, in MX_SPI1_Init - HAL_SPI_Init - HAL_SPI_MspInit it sets up NodeConfig.Init.SrcDataWidth = DMA_SRC_DATAWIDTH_WORD; NodeConfig.Init.DestDataWidth = DMA_DEST_DATAWIDTH_HALFWORD;builds the node (whatever that is), inserts it into the correct DMA channel, sets circular mode, basically looks like magic but I can imagine what it is doing. But then the stuff in the NodeConfig doesn't get applied to handle_GPDMA1_Channel1, so later when I finally call HAL_SPI_TransmitReceive_DMA, it gets grumpy around line 2230 because hspi->hdmarx->Init is all zeros still. It never got updated maybe?I think there is a problem with HAL_SPI_M

A while ago I auto updated to 2.0.0. Prior to that, I was able to change the repository location. The instructions were nicely noted here: https://community.st.com/t5/stm32cubeide-mcus/how-to-change-the-repository-directory-location/m-p/114938 Now with 2.0.0, the Firmware Updater option is missing from from Windows -> Preferences:  I don't see anything listed in the release notes document found here: https://www.st.com/resource/en/release_note/rn0114-stm32cubeide-release-v200-stmicroelectronics.pdf Has this functionality been completely removed and we're now forced to have our repository in our User account folder on Windows? FWIW, I also don't see a way of changing it in CubeMX. Thanks, C-Coder

I'm using STM32CubeMX for STM32N657x0HxQ controller. I would like to use ST ISP Library to handle MB1854 camera module. But I could not find the X-CUBE-ISP in STM32CubeMX Pinout & Configuration page, which is as follows. So I tried to import x-cube-isp.zip file downloaded from GitHub. But I came across the following error message. My STM32CubeMX version is Version 6.16.1 for Windows 11.

Hello so I am trying LTDC testing with cubeide 2.0 but I cannot use  __HAL_LTDC_LAYER_ENABLESo there's not defined LTDC and going and going afterI found that STM32H7S7xx symbol is not working So Is this cubeide 2.0's bug stuffs ?Or there's anything that I did wrong?

I'm using STM32N6570-DK board and developing an image processing application.When I tried to use STM32CubeMX to generate the project, I was able to set DCMIPP Pipe1 just like the attached screen capture.I would like to downsize the source image data to 800x480, but I could not find the option field in the DCMIPP Configuration view in STM32CubeMX.Is there something that I missed?My STM32CubeMX is Version 6.16.1 for Windows 11.  

(v2.21.0+) (Cube IDE)Hello everyone,I am currently working with the STM32N6 DK 570 board for an ST Innovation Fair 2026 project and wanted to share an important observation related to binary signing and boot behavior, which may help others working on this platform especially first-time users.Since the STM32N6 series has no internal flash, the device boots only signed binaries from external memory. Unsigned .bin or .hex files generated directly by STM32CubeIDE are rejected by the hardware, which is expected, but not very clearly emphasized in the current documentation.Observed Issue: Header Alignment RequirementWhile signing binaries using STM32_SigningTool_CLI v2.21.0 and later, I faced repeated boot failures (black screen) even though the binary was correctly signed.After debugging, I observed the following:The STM32N6 ROM expects the application header at a 0x400 offsetNewer versions of the signing tool do not automatically pad or align the binaryWithout explicit alignment, the First
