Hi, I’m really liking the STM32CubeIDE Extension for VSCode. Definitely a huge leap forward.One of the few things that I miss from STM32CubeIDE based on Eclipse (the “old” one) is the variable Watch (not live watch, regular watch) speed. It seems significantly slower on VSCode. I deal with a lot of multidimensional matrices so it’s very noticeable for me. Additionally, I know I can run some preRunCommands to set the watch variables to hex. But I cannot seem to figure out how to change them to binary or back to decimal while I’m debugging. This is a feature I use a lot since I deal with mixed formats in my projects. Any help is much appreciatedThanks

Hello,We are designing a custom board based on the STM32MP157FAC1 device, which is available in the TFBGA361 package.In the STM32MP157F datasheet (Page 251), the recommended PCB design rules for the TFBGA361 package are provided. Snapshot is attached for your kind reference. However, we are unable to determine the recommended PCB pad size from the information given.Could you please clarify whether the recommended pad size corresponds to Dpad or Dsm, or advise which parameter should be used while designing the PCB footprint?Regards,Prashant

Hello, I was wondering where the installed software packs are stored on the disk? I would like to have a look at the content and the examples, assuming e.g. the HAL pack or the Nucleo board pack contains these examples.

Hi all,I am wondering if CubeMX2 + STM32C562RE are able to support cpp main applications? Thanks in advance

When I open a VS Code workspace containing a project generated by STM32CubeMX, Windows Defender consistently detects Trojan:Win64/jscramSteal.DA!MTB.Environment: VS Code: 1.127.0 ST extension: 3.9.0 STM32CubeMX: 6.18.0 Windows: 25H2 (defender updated today) Steps to reproduce: Generate a project using STM32CubeMX. Open the generated project as a workspace in VS Code with the ST extension installed. Windows Defender immediately reports Trojan:Win64/jscramSteal.DA!MTB. Could you confirm whether this is a known false positive? If so, is there a recommended workaround, or is there an update available that resolves the issue?

The FDCAN_RxHeaderTypeDef typedef (for the STM32G4) includes:uint32_t IsFilterMatchingFrame; /*!< Specifies whether the accepted frame did not match any Rx filter. Acceptance of non-matching frames may be enabled via HAL_FDCAN_ConfigGlobalFilter(). This parameter takes 0 if the frame matched an Rx filter or 1 if it did not match any Rx filter */From the code, this member is loaded with the ANMF bit of an RX FIFO element. The documentation for this shows that ANMF is an abbreviation for “Accepted non-matching frame” - so the comment is correct (‘1’ → did not match a filter). Which means the member name should be something like ‘IsNotFilterMatchingFrame’.Code completion within CubeIDE does not show the comment:which means it is easy to get the state wrong if the name is interpreted semantically!Probably not a lot that can be d

Hi everyone,I am relatively new to the ST ecosystem, coming primarily from a web development and programmatic software background.I recently built a browser-based daily logic game tailored for my local market called hang 5. The core mechanics rely on a responsive visual letter grid, basic string matching for user inputs, and a specific vowel-penalty state machine.As a hobby project, I want to build a physical, standalone desktop version of this puzzle using an STM32 board and a small capacitive touch TFT display. I've been researching TouchGFX to handle the UI, as it seems more than capable of replicating the clean CSS grid layout I am currently using on the web version.Before I purchase my first board, I have two quick questions: Which STM32 Discovery kit would you recommend for a beginner wanting to utilize TouchGFX for a snappy, interactive 2D touch grid? The game requires a daily dictionary array of about 2,500 words. Is storing this plain text array directly in the internal flas

Hello, I am searching for a way to configure the VL53L9CX under linux using I2C.For previous sensors, a platform-independant driver library was available, but I am failing to find such a library here. How could I get a library that runs under linux, or even just a library without HAL so I can implement it myself using ioctl? Cheers,Daniel

Hello,When I right-click - create a new .c source file in a new STM32CubeIDE TouchGFX project, the file gets created in the STM32CubeIDE/Appli/Application/User/Core directory.  However, all the project source files are under Appli/Core/Src and headers in Appli/Core/Inc.  Is this normal and ok?  Why have the separate source file locations?Thank you 

Summary: With the STM32Cube VS Code extension (3.9.0, bundle-based), launching a default stlinkgdbtarget debug configuration fails with a GDB timeout and no visible server error. Root cause found: the extension does not pass the CubeProgrammer path when spawning the bundled ST-LINK_gdbserver, which then dies parsing its factory config.txt (the -cp line still contains the literal placeholder). Two workarounds verified below. Question: is the automatic path resolution expected to work for classic CubeMX CMake projects, or is this a bug? [Part Number] STM32H753ZITx (NUCLEO-H753ZI, on-board STLINK-V3)[Environment]STM32CubeIDE for VS Code extension 3.9.0 (bundle-manager based), Windows Project: classic STM32CubeMX 6.16 generated CMake project (not CubeMX2) Bundles under %LOCALAPPDATA%\stm32cube\bundles: stlink-gdbserver 7.12.0+st.2 and 7.13.0+st.3; programmer 2.21.0 and 2.22.0+st.1[Details — symptoms]F5 on the default configuration fails with:bound doStepConnectToTarget Failed: Remote repli

I have replicated the MB1936 Schematic for a dash-cam system based on the MP257FAIx series by choosing the relevant circuits from the reference to design my custom PCB. I would love to seek help from the community for the following requirement. If anything pops up my mind, I shall update on this thread - Can I use the 5-pin MOLEX/JST GH Signal Connectors to interface the Waveshare IMX335 USB Camera Module? I have used the USB Host Port Architecture to implement my logic, and it has worked well. Kindly find the Schematics PDF for your reference. Thank You!

 I’m working with my stm32f769-DISCOvery board.I’m trying to work through a few things that are unfinished/missing with the various buildroot configs on github and the stock one in buildroot.On boot, it crashes like this:[    1.705669] Unhandled exception: IPSR = 00000006 LR = fffffffd I’m apparently hitting an error with binutils newer than 2.28.1.It’s looking like this report, except I have also managed to get fffffff1 instead of fffffffdhttps://github.com/fdu/STM32F769I-disco_Buildroot/issues/1#issue-340504566This emcraft patch seems to be intended to mitigate the crash:https://github.com/EmcraftSystems/linux-upstream/commit/2882de1d86bd536c855feee582d44722434c2ac9In theory, the fix should be upstream as as well, and the 5.15 kernel i’m playing with should be new enough.

Hi everyone,I designed a board around the STM32G474 and I'm trying to use an external 24 MHz HSE crystal, but the crystal won't run under any configuration — the generated SystemClock_Config() call to HAL_RCC_OscConfig() returns HAL_ERROR and I land straight in Error_Handler() (infinite while(1) loop).Crystal I'm using:Manufacturer: Diodes Incorporated Part Number: FL2400159 Frequency: 24.0000 MHz Package: 3.2 x 2.5 mm, 4-pad ceramic SMD (Saronix-eCera FL series) Load Capacitance (CL): 18 pF ESR (Equivalent Series Resistance): 30 Ω Frequency Tolerance: ±10 ppm Frequency Stability: ±15 ppm Operating temperature: -40°C ~ +85°CLoad capacitor values I've tried (0603 package, X7R):22 pF 12 pF 28 pFSame result with all three: error.

In the editor pane’s menu row, the icon to enter Code is hidden under “...”. As it’s one of the most used things here, please change it with something else, e.g. the smileys (which are entirely unneeded in a technical forum), or the 3 line alighment icons (which are extremely rarely used in a technical forum), to be always directly present in the editor.JW

Hi,I want to use multiple VL53L8CX in my robot. I don’t like to connect a gpio to each of them nor use an gpio extender. In some other topic it is stated that MISO is connected with 47k to GND because the pin may configured as other than push/pull and the GPIO stated in datasheet are not really GP any more. So I got the idea to use MISO in I2C as a chained input to the next sensors LPn. There is nothing stated in datasheet other than don’t connect in I2C mode. So the questions are:is the state of MISO is defined at startup in I2C mode? Is it correlated to NCS pin even in I2C mode?after pushing the firmware and changing the I2C address is it possible to set MISO to high level independent to NCS or is it somekind hardwired?Ragards Chris

Hi all,I'm designing the control electronics for an automatic egg-candling machine (150 positions). An STM32F411 drives everything over a single shared SPI bus:A 74HC595 daisy-chain (shift registers → ULN2803A → solenoid valves) MCP3208 ADCs (reading LDR light sensors) on the same SPI bus, CS-selectedThe process is strictly sequential (read all sensors first, then actuate valves — never at the same time), so valve-switching noise never coincides with an ADC read, and SPI speed is not time-critical. That's why I want to keep the clock slow.Physical signal path (my concern):~100 cm total PCB trace 2 board-to-board connectors (PCB-to-PCB) then a 20 cm cable that enters the target IC (74HC595 / MCP3208) Planned SPI clock: 100 kHz, SPI mode 0, 3.3 V logicMitigations planned: series termination on SCLK/MOSI/LATCH at the source, ground interleaving in the cable, star grounding (valve PGND separated from SPI/logic GND), local 3.3 V regulation at the far end.My own bench test: I ran an SPI loop

Hello Friends, I have selected STM32F401XE series for my new project. The device is expected to face road vibrations and shocks, so to make system more reliable I am thinking to use MEMS oscillator rather than standard Quartz Crystal. I tried to search any reference schematic of STM32 MCU having MEMS osciilator but couldn’t find. Please share if any information available on how to use MEMS Oscillator.  I understand  OSC-IN should be connected to OUT of MEMS Oscillator and OSC-OUT should be set to high -Z.   What about VDD of MEMS Oscillator?  Should it be set to same VDD as set in STM32F401XE MCU, which is 3.3V Thanks

Hello I’m developing long project.Tomorrow I open the project and try to save it without any modification,but appears this window  Can someone please help me, thankyou in advance.

Hello, I have tested, the VL53L8CX tof sensor in interior (fixation at 3m10), and the visualization of the matrices works very well, in an empty scene or with a person pass under the sensor. When my sensor is fixed at the same height, but light up with daylight, next to the window, my matrices are noised, and when a person pass under it, there are some noise with the passage of the person. For example, the sensor create lots of pixels with this situation rather than the other. How to reduce this noise and this sensibility to the daylight ? 

Hi, there,we recently development a set up using vl53L1CB to measure water level.During our test the sigal noise ratio is pretty good(1000/1), however, we got a very close distance (20-30mm) at real distance around 6-8m. Similar phenomenon did not occur at solid surface even at 8m.And also, since we got a pretty good measurement at 8m with a solid surface, is there any possibility that we can break the firmware limit to reach a even longer distance?Is there any possible suggestion?thank you

Hi everyone,I am trying to generate a professional SBOM for my project.I have a few questions regarding the best workflow:Tooling & Detection: What the best tool to generate the SBOM.I tried using ScanCode, but it didn't find any component in my project (e.g., FreeRTOS). I had to manually add .about files to the folder to get results. Is there a better tool that can generate the SBOM with minimal manual intervention?ST Cube SBOM : The Cube MCU packages contain dozens of libraries (FatFS, FreeRTOS, USB_Host, etc.). If my project only uses FatFS, the package JSON still lists everything. Do I have to manually extract the components I use from the ST JSON? how to get use of the ST SBOM?I’d love to hear if anyone has a script or a specific toolchain that automates this without the manual "copy-paste" from the ST manifests Thank you!Yahya  

Hi there !I have a quick question about where the data are save. If i create one const array [1024] the data inside the array (because i write the word const in front) are save inside the falsh ? and this give to me more space in the ram  right ? and is the same if i create one struct and i acces with pointer ?  and please some one can help me and show where i can find all this kind of information like book tutorial website youtube ectThank you Sergio
