Are there any expansion boards with Quad SPI NOR Flash chips? I am interested in using it with a NUCLEO-WB55RG board.Preferably it should use the Macronix 25L6433FM2I-08G chip, but that is not a hard requirement. This chip is found on the X-NUCLEO-GFX01M2 board, but it is implemented as a standard single SPI interface.Thanks

Is there any way to optimize the IPD BALFHB-WL-01D3 to work at 865MHz at 22dbm for STM32WL55? And is there any hardware design guide for power of STM32WL like it is there Hardware design guide for STM32L0 application note AN4467.

Trying to run timer2 to set pwm signal for the BLUE LED (PA5).The MCU is STM32U083MCT6 and I used rm for STM32U083MC series (https://www.st.com/resource/en/reference_manual/rm0503-stm32u0-series-advanced-armbased-32bit-mcus-stmicroelectronics.pdf)I set each bit and register separately to be sure that everything is set correctly, but still miss something related to TIM2.What settings to check related to TIM2 and what is the best approach to configure timers of this MCU?

I all,I have a question regarding the EVSPIN32G4 board, specifically concerning the feedback resistors used in the current sensing network (default value: 11 kΩ).I am considering replacing them with 150 kΩ resistors. My main concern is whether this significant change will trigger the Overcurrent Protection (OCP) prematurely or cause stability issues with the internal op-amps.Has anyone experimented with such values, or are there specific hardware limitations I should be aware of?Best regards, Jules

Hi everyone,I am working on a custom board based on the STM32U575RGT6 (TrustZone enabled, FreeRTOS). I have successfully ported the SBSFU example originally provided for the B-U585I-IOT02A.My configuration is:MCUBOOT_APP_IMAGE_NUMBER = 1 (Single combined S and NS image)No external loader.To meet my application needs, I added a custom FLASH_STORAGE area at the end of the flash for EEPROM emulation. To do this cleanly, I modified flash_layout.h to dynamically compute the available FLASH_NS_PARTITION_SIZE based on the remaining space.The Problem: When I use MCUBOOT_OVERWRITE_ONLY, the OTA update (via Y-Modem) works perfectly. However, when I try to use the Swap mode (by commenting out #define MCUBOOT_OVERWRITE_ONLY), the firmware download succeeds, the board reboots, the bootloader validates the signature, starts the swap process, but then crashes with a status write fail:FWUPDATE --- Démarrage de la mi

Split from: Evaluation of Encoder Signal Level Shifting Approach as that was a different issue, and has been solved.I am also working with this same issue, in my case i have a encoder operating at 24V, and signal in comparable frequency i have implemented a simple voltage divider, the circuit works just fine, but as i don't have equipment to measure the noise and also i would prefer to have galvanic separation to my MCU, so in this case is there any good suggested  level shifter or optocoupler, should i combine the both strategy of voltage divider and optocoupler or just 1 is fine (from perspective of noise and safety)?

Hello,I'm trying to get familiar with the STM32Cube extension for VSCode.I generated a basic STM32 project using STM32CubeMX, for my NUCLEO-H723ZG board.I then imported the generated cmake project using the extension tool, and configured it using the "setup STM32Cube project(s)" button of the extension, which created a launch.json file.When I try to run the debug config, I get the following error : bound doStepSettingsValidation Failed: Device not found: Error: Missing CMSIS_PACK_ROOTHere is the STM32Cube core output :025-10-20 16:19:33.002 [Info] Adding STM32Cube CLI path to environment: c:\Users\Jacques\.vscode\extensions\stmicroelectronics.stm32cube-ide-core-1.0.3\resources\binaries\win32\x86_64 2025-10-20 16:19:33.057 [Info] Configuring CMSIS_PACK_ROOT environment: C:\Users\Jacques\AppData\Local\stm32cube\packs 2025-10-20 16:19:33.099 [Info] Configuring CUBE_BUNDLE_PATH environment: C:\Users\Jacques\AppData\Local\stm32cube\bundles 2025-10-20 16:19:33.805 [Info] cube wrapper version

Hi all!I'm handling project which use communicate RMII TCP/IP. if i set up CPU clock is 200Mhz as picture 1, the system run OK, i can ping network but my system require CPU clock is 400Mhz. if i set up CPU clock is 400Mhz, the connection between board and serve was intermitten. can you help to take alook and share me solution to set CPU clock 400Mhz and can run RMII.   

According to Datasheet, I2C of STM32F413VGT can be increased to 1 MHz, is it possible?    

안녕하세요. 저는 개인 개발자 입니다. 이번에 steval ctm051 보드를 구입해서 srm 을 공부하려는 데 소스코드를 제공할 수 있다고 해서 어떻게하면 소스코드를 제공 받을 수 있는지 알려 주시면 감사하겠습니다. Please note that the forum is English-speaking, which is why I have machine-translated your question into English: Hello. I am an individual developer. I recently purchased the steval-ctm051 board and would like to study SRM. I was told that the source code can be provided, so I would appreciate it if you could let me know how I can obtain the source code.

Hello everyone, I am new to STM32 and recently purchased the STM32 NUCLEO‑F446RE development board to start learning microcontrollers. While studying the clock configuration, I saw the option to use HSE (High Speed External oscillator). Since I am a beginner, I searched about it and found suggestions saying that I may need to add an external crystal and capacitors and solder them onto the Nucleo board. However, I am not sure whether this is actually required for this board. I also read that the Nucleo board might provide an 8 MHz clock from the onboard ST-LINK via MCO, which can be used as the HSE source. So I would like to clarify: Do I need to add an external crystal oscillator to use HSE on this board? If yes, what crystal frequency and capacitor values are recommended? Can anyone suggest reliable components or purchase links for the required oscillator? I would appreciate any guidance. Thank you!

When I calling NVIC_SystemReset() in the os task, the system will enter into hard fault handler error, so I have to call NVIC_SystemReset() again in the HardFault_Handler() to reset the system, so what is the proper way to call NVIC_SystemReset() in the os task?  

Upgraded STM32CubeIDE to 2.0.0 and struggling with issues!Installed CubeMX as a standalone program too. Now I'm confused how to create a STM32 project and as usual select C++ as the target language. 1- Should I start from the IDE? There'll be no .ioc file then!2- Should I start from CudeMX? There'll be no option to select C++ as the target language! How to fix it?My purpose is to keep main.c, create .hpp, .cpp files and include the header in main.c to be able to call the functions defined in the .cpp file.

The STRD/LDRD instructions store and load a 64-bit value. Internally, they are broken up into 2x 32-bit accesses.Since the element size is a word and not a double-word, they are not atomic in the same way that a uint32_t is atomic. Questions are:Is this instruction interruptible between the first and second 32-bit accesses?If the instruction does get interrupted, does it restart or resume? If it restarts, it will re-write the first word, for a total of 3x 32-bit accesses. If it resumes, it will only write the last word.The ARM reference manual has this to say on the subject:https://developer.arm.com/documentation/ddi0403/latestTo me, it seems they are restarted based on this text, but the two "might" words here leave ambiguity. But let's not rely on manuals or what people say on the internet. What actually happens in the hardware?

I am wishing to write two floating point values to flash memory at time.  I understand it is best to write 64 bits at a time, hence my writing two floats at once. This question is about using a union to structure the data. This code won't compile for the STM32L412KB.  Could someone please show me where I am going wrong? error on line 17.  Thanks.struct dual { float v1; float v2; }; struct dual two_readings = {1.23, 4.56}; union gemini { struct dual left; uint64_t right; }; union gemini value; value.right=0; 

Hello everyone,I’m working with the STM32N6570-DK and trying to bring up a TouchGFX project by following the official STM tutorial:https://www.youtube.com/watch?v=NFljjd_vQGAI generated the project with TouchGFX Designer and programmed the board using STM32CubeProgrammer exactly as shown in this one:FSBL flashed at address: 0x7000 0000Application flashed at address: 0x7010 0000The flashing process completes without any errors.However, when the board boots, the GUI is completely corrupted. The display only shows colored noise/static like in the video I attached.It seems like framebuffer data, LTDC configuration, cache handling, or memory mapping might be wrong… but everything was generated by TouchGFX. Any guidance would be greatly appreciated.Thank you!

Hi everyone,i am using the stm32g0b1cet6 controller. in which I am working with flash memory. I am using the FLASH_WaitForLastOperation function. In that function, one flash SR register's CFGBSY bit is not reset, and due to that all other flash write and erase processes it not working. this issue is coming randomly. before calling FLASH_WaitForLastOperation function I am clearing error flags as shown below __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_OPTVERR);__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_OPERR);__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_PROGERR);__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_WRPERR);__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_PGAERR); __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_SIZERR);__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_PGSERR);__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_MISERR);__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_FASTERR);__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_RDERR); can someone please provide some input ASAP.      

Hello everyone,im trying to send a simple "Hello World" via UART to my Laptop and read in the PuTTY Terminal on my on NUCLEO-H7S3L8 Board, But i tried everything, i cant revieve anything!!! Tried every UART/USART Port in the CubeMX. Nothing on my other NUCLEO-F303RE worked it instantly. These are settings in the CubeMX. i Used USART3 and selected Pins PD8 and PD9. i connected the Board to my Laptop. Set the Baud Rate to 115200 and also looked up the correct COM Port. Here is the test code and see Screenshots below. Maybe something in the CubeProgrammer??? UART_HandleTypeDef huart3; /* USER CODE BEGIN PV */uint8_t tx_buffer[] = "Hello World!\r\n"; ... while (1){/* USER CODE END WHILE */HAL_UART_Transmit(&huart3, tx_buffer, sizeof(tx_buffer), 100);HAL_Delay(100); /* USER CODE BEGIN 3 */}/* USER CODE END 3 */}

I can use a motor profiler with a custom board, but can I use a motor pilot with the same software? Is it possible to use a motor pilot with a custom board?  

STM32MP151 is a PTP slave clock, and the master clock is correctly determined and configured. In the same network, multicast, E2E, and one-step configuration modes are used. Run ptp4l，Output prompt: "Received SYNC without timestamp". the actual SYNC message of the main clock has a hardware timestamp.Other relevant information can be found in the info1. log file.STM32MP151 is the PTP slave clock IP: 192.168.1.251, the PTP master clock IP: 192.168.1.3, Captured data packet shows that the master clock has a timestamp, and the slave clock DELAY_REQ  has no timestamp.翻译搜索复制

I hope to achieve the scrolling effect like the file browser of Windows. I attached a demo video.

Hello, I'm currently designing a BDC-motor controller with the STSPIN840 and was wondering how low I can go with the current sensing resistors to minimize the losses across those resistors. Especially at higher currents in parallel mode the resistor losses would become quite large when staying in the region the eval-board is dimensioned. Is there a minimum sense voltage that I should stay above or is it going to be stable no matter how low I push it (assuming the reference voltage is reasonably stable)?Can I use like 50mOhms there? That would result in a reference voltage of 0.15V when using the 3A limit, so I could probably get away with a single 0.5W sense-resistor.
