STM32CubeIDE v2.2 has left all of our code in question. We need guidance with the CMake since we no longer have any helper dialogs of the old IDE to create a project within the new framework that matches the old IDE. list of helpful guidesNo HAL is neededa CMSIS and DFP environment for the selected processorCMake snippets that allow us to create and include legacy library code (adjusted for new processor)methods to control code optimization for code sections and filesdirectory structure methodsbasic commands to show what size of code we just compiled and output formats ie .hexWe believe this would be a great tutorial to ease the transition. I’m sure I have missed many other features of the old environment that you will quickly attend to.Any guidance that doesn’t require 200 hours of head banging appreciated. Glenn

Hello STM32N6 Tech support I am writing with reference to power on sequence. My power sequence is as follow1. First VDDA1V8_AON, VBAT and VDD is applied. My VDDIO4 & VDDIO5 is also connected with VDD.2. VDDCORE is supplied from an external SMPS step-down converter. We applied VDDCORE when the PWR_ON signal is high. VDDCORE is also connected with VDDCSI3. On the same PWR_ON my VDD3V3 is switched on. It is connected with VDD33USB.4. On the same PWR_ON my VDDA1V8 is connected. However, the input voltage of VDDA1V8 (linear regulator) is connected with VDD3V3. VDDA1V8 is connected with VDDA18CSI, VDDA18USB, VDDA18ADC.Can you please explain the above mentioned sequence will work for powering on STM32N6. I need comments on the following.1. Step 3 & Step 4 is not strictly defined in Getting started with hardware development for STM32N6 MCUs - Application note.pdf and an6000-how-to-build-the-discrete-power-supply-for-stm32n6-mcus-stmicroelectronics.pdf.2.

Hello, I am experiencing a reproducible issue with STM32CubeMX when generating a project for the first time on our U: drive. Our environment is part of an Active Directory domain, and each user has a U: drive mapped to their personal network home folder. Error in STM32CubeMX.logDuring generation, CubeMX successfully creates several temporary files in:  U:\FreeRTOS_M2\testv10\MXTmpFiles\ For example:  17:02:54.994 oldGeneratedFile ...\rtos_kernelStart.tmp_save17:02:55.076 Generated code: ...\rtos_kernelStart.tmp However, during the next generation pass, CubeMX tries to access the .tmp_save file again:  17:02:56.195 oldGeneratedFile ...\rtos_kernelStart.tmp_save17:02:56.200 ERROR ProjectBuilderjava.io.FileNotFoundException:U:\FreeRTOS_M2\testv10\MXTmpFiles\rtos_kernelStart.tmp_save(The system cannot find the file specified) 2026-09-03 17:02:55,707 [INFO] CodeEngine:297 - oldGeneratedFile, U:\FreeRTOS_M2\testv10\MXTmpFiles\rtos_threads.tmp_save2026-09-03 17:02:55,774 [INFO] CodeEngine:321

Hello,I am looking for an existing implementation of the SAE J2716 SENT (Single Edge Nibble Transmission) protocol for an STM32L4xx device.My goal is to interface with sensors that use the SENT protocol and decode the incoming data stream on the MCU.At the moment, my idea is to use:A timer channel configured in Input Capture mode to measure pulse widths. DMA to transfer captured timer values with minimal CPU overhead. Some form of interrupt or callback to process a complete 32-bit SENT message (24-bit payload + CRC + Status nibble).Since this requires coordinating several hardware peripherals (timer, input capture, DMA, interrupts, and frame decoding), I would like to know whether ST already provides any of the following:Application notes related to SENT reception. Example projects demonstrating SENT decoding. STM32Cube examples, Middleware, libraries, or reusable classes implementing the SENT protocol.If anyone has experience implementing SENT on STM32L4 devices, I would appreciate an

When testing the gyroscope of this product (LSM6DSV80X) we noticed that the noise density on each gyro axis is different with z being the lowest. This was observed on the dev-board (STEVALSMKI109DA) both in high performance and HAODR modes. The ratio between x and z is particularly noteworthy. Is there an explanation for this? The datasheet only reports one noise density so I am assuming that all axis should be the same. The same characteristics has been found on two different units. N.B.: Plain implies high performance. Rn is the noise density 

Hi,The project was created in stm32mx from the example project cortexm_sysk.It was generated as a CMake project and developed using VS Code.The "USB Device Middleware Library MCU Software Component" library, version "V2.11.4 / 11-April-2025", was manually added.CDC alone OKUVC alone OKCDC/HID OKCDC/UVC NOT OKSee file in attachment.I noticed the file descriptor is large (239 bytes). Is that a problem?Is there another setting I need to change?Regards,Sébastien

Hi,I am using the STM32H563ZI with the MB1404C board and running the “I3C_Controller_HotJoin_IT” example from the following repository: https://github.com/STMicroelectronics/STM32CubeH5/tree/main/Projects/NUCLEO-H563ZI/Examples/I3C/I3C_Controller_HotJoin_IT.The target device is a different board, not another STM32H563ZI - for example, the “I3C Protocol Analyzer and Exerciser” from Prodigy Technovations.After initializing the I3C controller and connecting the I3C target device to the bus, the SCL line of the I3C controller continuously toggles.Using STM32 Sidekick, I identified the following errata:Errata: Constant SCL Ticking with I3C Controller on STM32H563ZI1. Known Issue DescriptionWhen using the STM32H563ZI in I3C controller mode (such as with the I3C_Controller_HotJoin_IT example), there is a documented errata where, after initialization, the controller may incorrectly detect the SDA line as low, interpret it as a start request, and activate the SCL clock. This results in the cont

i meet this erro，and i resolved it by go window---Fireware updater----Check connection. then i can connect the internet, and connection to my account. Finally, I suspect it might be a problem with the network. You can try changing to a different network first. For example, you can use your mobile phone to create a hotspot.

HelloI’m using TouchGFX 4.26.0 on a STM32H747 and want to use RGB compression of the bitmaps to get the size of the firmware image smaller. To prevent performance loss, all bitmaps are loaded into the cache at startup. I have enough free SDRAM for the cache, so this is the easiest method and doesn’t require manual maintenance when adding / removing bitmaps to the project.Because the displays native orientation differs from the application orientation, image rotation is set to 90° by default.The code to load the bitmaps is shown below. This function is called at the end of TouchGFXHAL::initialize()​void loadAllBitmapsIntoCache(){ const uint16_t totalBitmaps = BitmapDatabase::getInstanceSize(); for (uint16_t id = 0; id < totalBitmaps; ++id) { touchgfx::Bitmap bmp { id }; auto format = bmp.getFormat(); bool ok; if (format == touchgfx::Bitmap::BitmapFormat::COMPRESSED_RGB565 || format == touchgfx::Bitmap::BitmapFormat::COMPRESSED_ARGB8888 ) { ok = touchgfx::Bitmap::decompressR

For first time programming this IC the reset pulse should go high to low for 4ms then it should comeback to high like a pulse which is programmer to use ?STLINK-V3MINIE - will be suitable ?Suggested for this requirement a programmer.MPN : STM32L021D4P7

Hi,I have read about the capabilities of the STM32G030P6T6 microcontroller, and they are truly excellent. Is it possible to implement any desired effect for WS2812 LEDs using this microcontroller without an HSE crystal?Are there any limitations?

We encountered an issue with the MPXM2053GS sensors: several units showed no output after SMT assembly. Decap analysis revealed that the die in the failed parts was damaged. We would like to understand whether this was caused by mechanical mishandling or other factors, and what measures can be taken to prevent recurrence. 

Hi Sir, May i ask you to get the latest version 6.6 CMRT FOR TIP147,Thanks. Best Regard,Victor Lai

Hello everyone,I’m working with an STM32F103C8T6 (Blue Pill) development board and facing an issue while trying to program/debug the MCU using ST-Link V2.Board used:https://robocraze.com/products/stm32f103c8t6-arm-development-boardIssue details:STM32CubeProgrammer / STM32CubeIDE does not consistently detect the targetSometimes shows “No target connected” or fails during connectionTried SWD mode with NRST connectedBOOT0 is set to 0 (Flash mode)Power supplied via USB (5V) and also tested with external 3.3VChecked SWDIO, SWCLK, GND continuityI’m not sure if this is related to board configuration, clock settings, or ST-Link connection parameters.

Hello Experts,I am working on the STM32MP257F-EV1 board (MB1936 Var1.0 Rev.C-01) and following the official OpenSTDroid provisioning guide. I have successfully used flash-device(STM32CubeProgrammer v2.22.0 ) to flash the full eMMC starter image via DFU mode (FlashLayout_emmc_cm33tdcid.tsv). After that, I switched the boot mode from DFU to eMMC (M33-TD) and pressed USER2 + RESET to enter fastboot mode, as described in the documentation. However, instead of entering fastboot, the board goes into an infinite reboot loop.Observed behavior: Serial console (minicom) shows the following repeated sequence: iac exceptions: [159:128]=0x000001IAC exception ID: 128Ooops...[INF] System reset[INF] Reset reason: System reset (SYSRST) (0x94)[INF] init:pmic@33 STPMIC:20 V1.1[INF] welcome to MCUboot: TF-Mv2.1.3-4-g0a94de886[INF] cpu: STM32MP257FAI Rev.?[INF] board: stm32mp257f eval1[INF] board ID: MB1936 Var1.0 Rev.C-01[INF] dts: stm32mp257f-ev1-cm33tdcid-ostl-emmc-bl2.dts[INF] boot device: sdmmc2[INF]

So our System works fine most of the time but sometimes the Reader does not detect the tag and we observe that rfalNfcState are just keep fluctuating between RFAL_NFC_STATE_POLL_TECHDETECT and  RFAL_NFC_STATE_LISTEN_TECHDETECT  same as when no tag present in the field of Reader and it is not able to satisfy this if condition.“if( rfalNfcIsDevActivated( rfalNfcGetState() ) ) // this if condition”We observed that even if we do controller reset it doesn’t fix the issue only when we power cycle the reader{st25r3911b} it start working again normally.I’m attaching the code with this i want your team to review it to let us know what exactly we are doing wrong which leading to this state where our rfal state machine not switching properly, With Restart_flag we are doing reinitialization i want you to review that whatever sequence we are following is correct or not  Main.c  {Rfid Reinitialization sequence}Please help us fix this issue and could you provide or help us that through software funct

We visually inspected the surface of the die of MPXM2053GS, which was covered by gel. We found some of them were not intact. there were holes and cracks on the gel. Although the electrical tests were passed but we are concerned about the long term reliability. Could someone advise if this is a normal phenomenon caused by the packaging process？

Hello,I’m recently working on utilizing ROM I2C bootloader on STM32C0116F6U6, Device ID: 0x443, Rev Z.It seems that bootloader is reporting wrong version 0x11 instead of 0x12, while I got reply to GET command (0x00) from protocol v1.2 instead of v1.1 - there is clearly a byte 21 (0xA1) in reply (which is protocol v1.2 according to AN4221). Get as well as get version command are both returning 0x11.Because of this bug utilities like stm32flash are failing by not reading all bytes after issuing get command. stm32flash will try to resync by writing bad command (0xFF) and waiting for NACK but bootloader can keep clock line low for up to 6.2s if all bytes from previous transaction were not read.LA outputs, Get version:  Get command is returning 0xA1 byte which should not be there:  stm32flash too short get command read (it was expecting protocol v1.1), clock line will be hold low for 6.23s after writing resync byte (0xFF):  

Hello Team,I am currently reviewing the Secure Manager memory layout described in UM3254 (Secure Manager for STM32H573xx microcontrollers). The document provides predefined flash memory mappings for STM32H573 devices, including the Large Profile layouts shown in Figure 9 and Figure 10.       Our plan is to use STM32H5F4, which provides 4 MB of Flash, and I would like to understand the recommended Secure Manager memory mapping for this device. Could you please help with the following:Is there a predefined Secure Manager flash layout available for STM32H5F4 (4 MB Flash)?If available, could you share the corresponding memory map.Could you point me to the exact documentation, application note, user manual section, or reference project that describes Secure Manager support for STM32H5F4 devices?If no predefined layout exists, could you provide guidance on how the memory regions should be scaled from the STM32H573 large profile/External Flash profile example to support 4 MB Flash devices? Th

I’ve implemented a sort of dynamic menu where there are 6 positions and you can resize the menu item to become 2x1 or 1x2 (see screenshot for a better understanding)It is achieved by a custom widget class built on top of ShapeThe elements can be dragged and moved around and I’m using handleDragEvent to achive that. When dragging around there’s a method that re-position the element to avoid overlapping.For some reason, sometimes, not always, when the elements are moved automatically around, some strange artifacts. Is there a reason for that; where should I watch?(at the moment I’m only using the simulator)artifactshow it should render
