Hello i use STM32G070CBT6 with PD0 and others pins.PD0 as input pin with no internal pull-up/down with extrenal 10k pullup gives only 0.7V, when i set the pin to output and set state to high there is 3.3V.Where is the problem? 

Dear ST Community,I am currently migrating my Firmware from STM32H723VG to STM32H563VI. I have problem with Internal Temp Sensor. Based on Reference Manual on both MCU reading temperature is the same, but it doesn't work as it should.When on STM32H7 I got about 750 (24 degree Celsius) on reading ADC from TEMP Sens, on STM32H5 I have around 100.I tried both with and without cache (ICache and DCache), with Bare Metal and Zephyr RTOS code. In every configuration it is not working. I tried also on different MCUs, so it shouldn't be part itself.It worked with Nucleo H563ZI, but doesn't with H563VI.What else can I do?

According to Page 1354 of rm0394, setting LDMA_TX bit must occur only when SPE=0.However, from my reading of the function HAL_SPI_Transmit_DMA, this bit may be set or cleared when the DataSize <= 8bit and MemDataAlignment == HALFWORD, even if SPE=1.This looks like a bug.Am I correct?STM32Cube MCU Package for STM32F4 STM32L4, version 1.28.3

Hi,among probably many other registers, the ITM registers like TCR and Stimulus Port Registers described in the ITM programmers model in ARM Cortex-M7 Processor TRM are missing. Which means I either have to adapt the svd file or go to memory view and translate and modify the registers manually. Is this on purpose and or are there plans to fix this? If you have a repository somewhere I can maybe fix that on my own and start PR.Ty in advance

I am setting up my STM32F303RET6 for four differential inputs to be sampled simultaneously. As seen in the screenshot attached. there is no option for differential inputs on CubeMX. Am I missing something here? I have reset whole project to ensure no pins are assigned elsewhere.

Hi I have a USB-C Connector that will be used for Power Delivery Sink  for charging and USB Full Speed Mode(12Mbps) for communicating with onboard STM32F767ZIT6. But only one thing will happen at a time.    As seen in the attached schematics, I have used STUSB4500 as PD Sink controller. I will communicate with it via I2C using STM32. I understand that this STUSB4500 will negotiate 20V(60W which i want for charging) with the source(which in this case is AC-DC Wall adapter) in Power Delivery Mode. But my question is during USB Full Speed Mode Communication with STM32, when that USB-C Receptable is connected to a PC instead of Wall Adapter. As during charging mode, USB_VBus is 20V and in Full Speed mode, it is 5V and my STM32 is Self-Powered and VBus sensing is mandatory. But due to USB VBus varying between 5V and 20V, I cant connect it to for example PA9 VBus sensing pin of STM32 using a voltage divider.  So, i was thinking maybe there is another option to sense

Hello Everyone,I’m still getting up to speed with the STM32N6 series, so apologies if my question seems off, but I’d really appreciate your help!I’m working on implementing object tracking using the STM32N6570-DK board with the MB1854B camera. I'm wondering if it’s possible to deploy OpenCV on this platform to support the tracking logic.If anyone has experience with this or knows of any courses, guides, or resources that could help me deploy OpenCV (or similar tracking frameworks) to the board, I’d be incredibly grateful.Also, if you have relevant experience and are open to offering support or consultancy, I’m more than happy to discuss compensation. Please feel free to reach out!Thanks in advance for your time and help!

Dear ST,I am searching for  LTE module , basic data transfer is to send 2Kb of data using mqtt and perform http opeartion.

Hello,after updating MEMS Studio to version 2.3.1 I am experiencing an issue when working with FSM configurations.Previously everything was working correctly, but now I cannot reload FSM configurations saved as JSON files.Steps to reproduce the issue:Create a new FSM in MEMS Studio.Save the configuration as a JSON file.Try to reopen the same JSON file.The file loads without any error message, but the FSM editor remains empty and the FSM configuration is not shown.However, individual FSM examples included in MEMS Studio open correctly without any issues.This happens both with:JSON files generated previously with an older version of MEMS StudioJSON files generated directly from example FSM projects in the current versionSo the issue does not seem to be related to the JSON content itself.My setup:MEMS Studio version: 2.3.1Sensor: LSM6DSOXQuestions:Has the FSM JSON handling changed in MEMS Studio 2.3.1?Is there a specific way to reopen a saved FSM configuration JSON?Is this a known issue o

I'm working on a design with an STM32L072CZT6TR, where I want to calibrate my main timebase. That main timebase is TIM6, which counts 16,000. The HSE is 16MHz, so there's an interrupt evey 1ms. Calibration is done by counting the number of HSE cycles between two consecutive PPS pulses from a GPS receiver. The PPS triggers an EXTI interrupt, which starts TIM21 and TIM22 at 0 on the first pulse, and reads the timer values on the second.TIM21 is set to count 16,000 pulses and TIM22 is slaved to TIM21. This way, I can conveniently determine whether the HSE is slow (TIM22 == 999) or fast (TIM22 == 1000), and calculate a correction based on TIM21.This logic is copied straight from an older design with an STM8, where it works like a charm. However, the cascading does not work. No matter what, TIM22 is always 0 on the second PPS. I have used CubeMX to set the timers up, and, going over the code with the reference manual as my guide, I can see no errors.

Hello,I’ve recently started using ST products and the IDE with CubeMX, which is why I’m asking for your help. I’ve just begun developing a communication system using a Nucleo H743ZI2; my goal is to set up a UART and a CAN bus.The UART is done; I used DMA access to optimize it. However, when I try to enable the CAN bus in Cube MX, I run into a problem with the clock configuration related to the bus.When I use the “Resolve Clock Issues” function, I get the error: “Cannot find a solution for some constraints.” Does anyone have any ideas to help me solve this problem? Thank you in advance, and have a great day,

Hi,I have a question about choosing some fairly basic security settings for an STM32H5.We are developing a system that uses both G4 and H5 micros. We have developed a largely common bootloader that receives a signed encrypted application over variously USB, UART, or CAN, and flashes it to internal memory. This is working on the G4 and H5.For the G4, we understand that if we select "Level 1" read protection, the bootloader will still be able to erase and re-flash a new application but a user will not be able to gain access to the code (bootloader, application, or data in CC RAM). Further, the G4 can be reverted to Level 0 if required, but this will erase the proprietary code.Ideally, we would like the same security behaviour on the H5. I have been reading about the bewildering selection of security settings with privileged and secure settings for individual peripherals but I feel this is more complicated than we require. Our bootloader already prevents someone installing malicious code

Hi,I am using the latest version of STM32Cube extension for VS Code (3.8.0). I created a simple project for STM32H735G-DK board using CMake as the toolchain and ST-ARM-CLANG as the compiler. I do not know if it is relevant, but I also enabled FreeRTOS and configured the USE_NEWLIB_REENTRANT option to Enabled.I generated the project and I am compiling it with VSCode. I changed in the starm-clang.make to use the NEWLIB instead of the PICOLIBC:set(STARM_TOOLCHAIN_CONFIG "STARM_NEWLIB")The compilation works, but clangd complains about some errors. In the output of clangd, I can see multiple instances of:D:\ST\stm32cube\bundles\st-arm-clang\21.1.1+st.6\bin\..\lib\clang-runtimes\multilib.yaml:47:3: error: unknown key 'IncludeDirs' IncludeDirs: ^~~~~~~~~~~ D:\ST\stm32cube\bundles\st-arm-clang\21.1.1+st.6\bin\..\lib\clang-runtimes\multilib.yaml:21:1: error: multilib "arm-none-eabi/armv4t_exn_rtti_size" specifies undefined group name "stdlibs" MultilibVersion: '1.0' ^and because of these erro

Is it ok to use different build configuations for different pinout version?As you may have experienced, sometimes pcb version how the pinout. Sometimes another UART or TIMER is used in another pin etc,... Is it ok to  use different build configuations for different pinout version?

A few direct questions about the current CubeMX2/HAL2 split. Are older STM32 series expected to stay on HAL1 + CubeMX permanently, or is there an actual plan to migrate them to HAL2 + CubeMX2? What is the long-term support model here?Are these two stacks supposed to coexist for years, or is HAL1/CubeMX effectively going into maintenance mode? Is there any official migration guide planned?Both for HAL1 → HAL2 API migration and CubeMX project → CubeMX2 project migration. How is the VS Code extension supposed to work with both ecosystems in practice?If one project is on CubeMX/HAL1 and another is on CubeMX2/HAL2, what is the intended workflow?Is proper support planned for both, or is the tooling mainly targeting the new stack? Where is the actual HAL1 vs HAL2 side-by-side data?Flash usage, RAM usage, performance, code size, same project, same MCU class, comparable build settings. Right now this looks like a major ecosystem split without a clear migration plan or hard technical

Typical bootloaders (including some of ST's built-in bootloaders for other processors) typically allow a code image to be loaded into the processor via some kind of serial link (UART, SPI, CAN, etc), without needing an ST-Link or other debug hardware. These make bootloaders ideal for in-field upgrades of products.OEMiROT/OEMuROT has some features of a bootloader, in that a new image can be placed in a special area of flash and (if it passes all the various checks) then be executed.However, there is no way of actually putting that image in flash without an ST-Link or similar, since this is needed to unlock the chip via the DA process. So if you want to do an in-field upgrade of your product's firmware without any debug hardware, OEMiROT in its current form isn't the solution.Our approach is for our application to download the image into a reserved area of RAM and then switch to the bootloader, where our adapted version of OEMiROT copies this image from RAM to the special area of flash.

Hello All,I have the NUCLEO-C562RE board and I wanted to get started with it. But I am lost and not able to find any documentation related to architecture manual or user manual. I am new to ST boards, previously I used Aurix TC375. Has someone here in the community used this board or similar one and know how to work around it? It would be really helpful.Thanks

Recently I’ve been learning about the updated STM32 software ecosystem, including the new HAL2 library and STM32CubeMX 2 tool. I have a few practical questions and would like to start a discussion with all STM32 developers here.   What are the new characteristics, improvements and advantages of HAL2 compared with the traditional HAL library?   Can STM32CubeMX 2 still support earlier and older STM32 MCUs, or does it only serve the latest chip series?   For those legacy STM32 microcontrollers, are they able to use the new HAL2 library, or can they only run the classic HAL as before?   If you have relevant development experience or official information, welcome to share your views and explanations.    

Hi, We are using an STM32F103 as a controller for a Half-bridge dc-dc convertor running at 110Khz. We are facing an issue where the microcontroller is resetting every minute when output crosses 12A. We disconnected all peripherals, removed all protections and kept only the PWM and reset problem sustains itself. On further inspection, we found that the PWM duration increases for a few cycles and then the microcontroller resets. It seems to us that the microcontroller clock slows down and then finally stops forcing a reset. We do not have watchdog timer implemented.We are using a 8MHz crystal. Please check attached image (CH1 - reset line, CH2 - Independent PWM, CH3 - Half bridge high side) The fun fact is that if we place the microcontroller on an external PCB and connect to the gate driver with wires, we do not see the microcontroller resetting. (even without the crystal). Sometimes, attaching an oscilloscope probe (1Mohm) also prevents restart. Currently,
