I'd like to share an open-source alternative to STM32Cube Build Analyzer, which may be useful for developers who don't use STM32CubeIDE (Eclipse or Visual Studio Code edition), or who build their projects using other tools such as Visual Studio or CMake directly.GCCMapAnalyzer | Source.(HTML file, hosted on GitHub Pages; click on GCCMapAnalyzer to run it in the browser.)FunctionalitiesTree view: Visualizes memory usage by memory region, section, and object file. Memory Map: Displays symbols and sections in an address-space line diagram. Section configuration: Allows customization of how sections are counted and grouped. NoteI hope this post does not violate Community Guideline #5. I originally developed this tool to visualize an STM32H7 .map file before I knew about STM32Cube Build Analyzer, and I thought it might be useful for other community members as well. 

The magnetometer doesn’t start over I2C and doesn’t output data via UART. Please help solve the problem; the files are attached.

  I am using STM32F411CEU6 Black Pill from WeAct. Stlink was working I was able to flash the code but now after testing when I tried to connect it wouldn't connect I keep getting this error. I am using stlink clone.  USB under DFU mode gets connected, full chip erase works but when I try to flash the code I get this error      Please help me out

Product: STM32CubeMX2 (.ioc2)Version: generic Linux 1.1.0Appeared with MCU: STM32C542CCU6HAL package: stm32c5xx_hal_drivers 2.1.0Project type: CMSIS-Toolbox / CMake generationSummary:On STM32C5, four ADC1 external channels (IN2, IN5, IN6, IN7) have an alternate GPIO pad selectable via the SBS_PMCR pin-remap bits (ADC1_IN2_REMAP -> PC4, IN5_REMAP -> PC5, IN6_REMAP -> PB0, IN7_REMAP -> PB1 on STM32C542). CubeMX2's pin configurator lets you assign the remapped pad in the graphical pinout, accepts it, and generates both the GPIO analog-mode config for that pad and the ADC channel/sequencer configuration for the channel. However, it never emits the corresponding SBS_PMCR remap-enable write. The generated firmware therefore samples the default (non-remapped) pad, while the pin the schematic actually uses is left unread.There is no generation warning, no build error, and no runtime fault. The ADC returns a stable, plausible, but wrong 12-bit code. Reproduction:1. Assign ADC1_IN7 t

Hi, its my first postLet me introduce myself, my name is Manuel, I am from Spain (English is not my native language) and I have joined the forum looking for help. My profile is that of a maker with very little programming experience (an AI maker). AI helped me a lot to make the programs I’m migrating a project from Arduino to an STM32 Blackpill; I managed to get it working on Arduino.Sim racing pedalsThe pedals are a potentiometer (for the accelerator) and a loaded cell (for the brake). Well, what I thought would be the hardest thing to do—getting the STM32 Blackpill to “read” those sensors—I’ve managed to do. I press buttons on the console and see the changes… but what was easy on Arduino—turning it into a game display for Windows—I’m not being able to do on the STM32… the libraries that Gemini recommends are either missing or don’t work… I’m looking for help getting Windows to recognize my STM32 as a gaming device. I thought this part would be easier; the Blackpil

Hi ST,I am working on STM32MP257 platform and I have read some of the previous topic and thread, seems that web multimedia is somewhat supported now by using Qt at its minimalist setting. But the previous claim of “ST is working on enabling chromium/ web browser, and expected to have it out by late 2025” hasn’t really got any update.Can we know if we really have a definitive answer or status update or is there any example or demo? 

Hi ST,Today I decided to give STM32CubeIDE for VS Code another try.I installed all 15 latest packages (Rev. 3.10).Using the STM32Cube Bundle Manager, I installed all required bundles, including Ninja 1.13.2.After opening in VS Code the folder containing the code generated by STM32CubeMX (CMake option) and trying to configure CMake for the first time (Ctrl+Shift+P → CMake: Configure), I received the error below.What am I missing? The last time I tried this several months ago, the project at least configured correctly and built successfully. Kind regards,Thomas [main] Configuring project: Firmware[driver] NOTE: You are configuring with preset Debug, but there are some overrides being applied from your VS Code settings.[proc] Executing command: "C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_TOOLCHAIN_FILE=C:/Projects/All-purpose-Micro-Controller-2/Firmware/cmake/gcc-arm-none

I’m designing another PCB for the STM32L452 LQFP48, and I was wondering - how big is the die? Can I see a picture of the structure of the LQFP 48 before it is encapsulated?I use double layer boards, and have as much ground plane under the micro, both top and bottom layer as possible. But I often sneak some power tracks around the inside perimeter of the micro. But under the plastic goo I do not know how big the die is. How far can I go with tracks before I am under the actual microprocessor? I think knowing the internal dimensions of the package would help me fine tune my printed circuit board designs.I suppose I could destroy one to find out, but that seems like a waste (and messy). I can’t imagine it would be company confidential… or could it? If a photo is confidential, how about a CAD drawing? … or maybe an artist’s impression... 

Hello ST community,I am trying to understand the current support status of USB composite devices when using the classic stm32-mw-usb-device middleware.I know that the classic USB Device middleware already contains `CompositeBuilder`, and I have seen ST tutorials using it to build composite devices. For example, the STM32H5 CDC + HID tutorial and the dual CDC ACM tutorial.However, those tutorials still require a lot of manual integration: editing `usbd_conf.h`, editing `usbd_conf.c`, manually writing class registration code, and manually maintaining the generated `USB_DEVICE` folder. This is quite fragile because future CubeMX regeneration can overwrite important changes.For newer stacks, USBX seems to have much better composite support, where all the relevant code for composite could be generated by CubeMX. My questions are:1. Is there currently any STM32CubeMX-supported MCU package that can directly generate a classic `stm32-mw-usb-device` composite project using `CompositeBuilder`, i

Hello ST team,  Could you please provide the steval-wbc2tx70 & STWBC2-HP documentation.

I have a Nucleo-F767ZI and have tried everything I know to get it going to no avail.  The problem seems to be relating to the ST Link.  After writing and compiling some code in STM32CubeIDE, I get the message that the ST-Link needs to be updated.  I go into STM32CubeProgrammer and attempt to do just that.  When I connect inside STM32CubeProgrammer, the app sees the board, I click on “Connect” and I can see data in various memory locations. However, when I attempt to “Upgrade Firmware”, that’s where the trouble starts. After clicking on Upgrade Firmware, the app reports nothing found.  I can disconnect the USB cable, reconnect, and STM32CubeProgrammer will see the board again.  The unfortunate thing is, I cannot use the board because STM32CubeIDE will not allow me to download.  The weird thing is, in the past, I have used the Arduino IDE to write code and program this board and it still works fine - no problems.  I just cannot get the native STM32CubeIDE and STM32CubeProgrammer to act r

Embedded veteran here, been involved in all manner of MCUs and MPUs professionally (especially safety-critical) but for personal use most of my prior experience has been with PIC16F and 18F (to save money obviously), of course those are only 8-bitters. I’m very interested in learning STM32 MCUs (gee they look ALMOST like DSPs except it’s single-cycle multiply not MAC and no simultaneous pointer adjustments etc.). Thing is my PIC experience has given me a pretty decent collection of chip initialization routines that I can adapt as necessary for small differences with peripheral features and such. My “inherent bias” is bare metal, no FreeRTOS, I understand I may be “going against the grain” a little but I want to get my hands on every nanosecond I may have coming. I don’t necessarily need this in C language, but I would like to get my hands on at least a very detailed list of all the HW registers that COULD need to be set, and the EXACT order in which this is “most safely accomplished”.

Hello,I am integrating the VD5943 image sensor with a Lattice FPGA acting as a MIPI CSI-2 receiver.I have reviewed both the VD5943 Datasheet (DS14968) and the Reference Manual (RM0532), but I could not find any information about the operating mode of the MIPI CSI-2 clock lane.Could someone from ST please clarify the following?Does the VD5943 transmit the MIPI CSI-2 clock in Continuous Clock mode or Non-Continuous Clock mode? If this behavior is configurable, which register controls it? If it is fixed, which mode is implemented by default?This information is important to ensure compatibility with our FPGA CSI-2 receiver and downstream processing.Thank you for your support.

Hello!I have a 5V incremental encoder that provides A, B, Z signals, and a STEVAL-CTM015V1 board for controlling an SRM motor. I don’t have access to the encoder controller to set its offset.Does the STEVAL-CTM015V1 have an autocalibration or learning function that, when the power supply is connected to the motor, will adjust the rotor’s position relative to the encoder’s zero position?Additionally, is access to the STEVAL-CTM015V1 settings panel blocked in any way, or should I simply use the STLINK-V3SET debugger as recommended in the documentation?Thank you for your help.

Could you share ST60A3H1 IBIS model?Due to ST60A3H1 include eUSB signal, we would like to simulate the eUSB signal integrity on our design layout.ThanksHank

STM32CubeIDEI have Project Directory (Fully populated from an earlier version of the IDE on a different machine)that I bundled up and then unwrapped on my new build machine.However, when I point my newly installed (up to date) IDE to my unwrapped Project directory,it “sees” the Project is there...but when I click “Finish” to bring it into my IDE, the IDE showsthe project (with the correct name) but devoid of any project properties...and no Source Code Tree(where I normally--and previously--could navigate all the source files).  I can see all the expected source code files in my Project DirectoryWhat is the disconnect?Do I need to manually edit the PROJECT.ioc or .project file (or .cproject or .settings or *something*) ?Is there a known issue with transferring a Project from an earlier version of the IDE?Guidance Appreciated!Paul++

We are interested in incorporating the STSAFE-A120 authentication chip (part number: STSAFA120S8SPL05) into our current design. However, the available datasheet lacks the necessary details for firmware development. We would highly appreciate your help and guidance on this matter. 

I'm using an L6561 to build a flyback circuit to control an LED with constant current. The input voltage is 220VAC 50Hz. The output controlling the LED is 12V 0.15A. I tested it with 12V 0.7A and the circuit worked very well with a power factor (PF) of 0.96 and THDI <10%. However, when testing with 12V 0.15A, the PF was 0.68 and THDI was around 40%. Could it be that the L6562 doesn't have a good power factor under light load?

"I recently bought an STM32F030C8T6 chip, but when I was programming it, I didn't enable the debug interface as Serial Wire. As a result, although the first programming was successful, I can no longer program it through the Serial Wire interface. How can I solve this problem?"

Hello,I am trying to create an FSBL XIP project for the NUCLEO-N657X0-Q with the following structure: FSBL running from internal SRAM Application executing in place from the external XSPI flash ThreadX and NetX Duo running in the Application context Ethernet using the onboard LAN8742 PHY External Memory Loader project The STM32CubeN6 firmware package contains two relevant examples: Projects/NUCLEO-N657X0-Q/Templates/Template_FSBL_XIP Projects/NUCLEO-N657X0-Q/Applications/NetXDuo/Nx_UDP_Echo_Client However, the two examples use different project structures.Template_FSBL_XIP provides the required FSBL, XIP Application, and External Memory Loader structure, but it does not contain the ThreadX, NetX Duo, and Ethernet application configuration.Nx_UDP_Echo_Client, on the other hand, contains the required ThreadX, NetX Duo, Ethernet, LAN8742, and UDP configuration, but the complete application is assigned to the FSBL context instead of being built as a separate XIP Application.Copyi

The “leave a reply” thing (clicking into which the editor appears) at the bottom of a thread appears/disappears as the thread is scrolled.This then leads to page “jumping” as it’s scrolled, as its size changes and things get recalculated on the fly.More importantly, the “appear” logic is wrong and when the page is resized to smaller size, that “thing” never appears.This - as all the other visual smog added for “modernity” - is entirely unnecessary and confusing. Just leave it there unconditionally.JW

I am working on STM32WL55 dual core in which the current consumption is as not as expected as according to the datasheet. It is hardcoded for high power only. and the current consumption is coming for +17dBm and +14dBm as expected which is 58mA and 45mA approax but when switching to the +20dBm and +22dBm it is getting capped at 68mA only. It is not going above 68mA at any way. I have hardcoded it to 22dBm but it is still getting capped to 68mA only. I want to do changes in the code in such a way that the current consumption changes. what are the possible reasons of it and what are the functions where the code modification can help in changing the current consumption. Is there that ST has capped it to +18dBm or +17dBM  and will never work above it? void SUBGRF_SetTxParams( uint8_t paSelect, int8_t power, RadioRampTimes_t rampTime ){uint8_t buf[2];int32_t max_power;if (paSelect == RFO_LP){max_power = RBI_GetRFOMaxPowerConfig(RBI_RFO_LP_MAXPOWER);if (power > max_power){power = max_powe
