The installation guide UM2563 hasn't been updated since 2022. Information about supported/tested Linux versions needs refresh.Also, in the release notes, if new Linux versions are validated, please add this information, it would be helpful.Regards,-- pa

Dear all,I want to set LIS2DUX12TR to detect if there is a motion of the board, like a theft detector.The board is battery powered, so, I was thought to use INT1 pin to wake my PIC18LF26K22 uC to send some data.For me, is for time when I interact with an accelerometer sensor, so, please be kind with me.I read the datasheet, and I found I must enable some function in registers (like bits in EMB_FUNC_EN_A, route interrupt to INT1 pin, send to sleep, etc)  but, I'm not sure which one.I wonder if there is a software, something to visually  configure register and at the final give me an output with modified register and just put the new values on LIS2DUX12TR, or , maybe, someone cold  indicate me what should I do.Thank you in advance for your time.Best regards LE: I don't have any special board, just the board with my uC and LIS2DUX12TR, so, I cannot use MEMS Studio (or I don't know how to use it offline)

Hi, I am a beginner STM32 user. I am exploring the STMCube ecosystem and some simple functions my MCU can do. However, I stuck on generating PWM signal (I simply dont get any signal on the pin, tried few different pins), which based on some youtube STMCube tutorials should be really easy. My hardware and clock setups are verified earlier, so the only thing wrong or incomplete is STMCube PWM configuration:The code: #include "main.h" TIM_HandleTypeDef htim9; void SystemClock_Config(void); static void MX_GPIO_Init(void); static void MX_TIM9_Init(void); int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_TIM9_Init(); HAL_TIM_PWM_Start(&htim9, TIM_CHANNEL_2); while (1) { } } void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; __HAL_RCC_PWR_CLK_ENABLE(); __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE3); RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_

ST VP Configuration - ST-Link - USB - SWIM - STM8S103F3I have connected the "SWIM" and "GND" pins of 'ST-LINK V2' to the development PCB includes "STM8S103F3", the supply from the mobile charger is connected through the USB port of the PCB.When I select 'Read all tabs', the message is shown as "Can't communicate with the device".Then I turned the power off and on by pressing the reset button low.When I tried to read the device, the message showed as "Device is protected".The LED is flashing in every condition.Each time the dongle LED glows initially, then flashes and then turns off.what is wrong? how to solve?

I'm having trouble uploading to or even properly recognising the STM32U585CIU6 (brand new chip from Mouser) this chip properly in the STM32CubeProgrammer 2.4.0 and hoping someone can help.I'm connecting UART via a generic FTDI, that is known to work fine connected to a STM32F411CEU6 for example.It sort of connects, see below:12:09:58 : STM32CubeProgrammer API v2.4.012:10:04 : Serial Port COM9 is successfully opened.12:10:04 : Port configuration: parity = even, baudrate = 115200, data-bit = 8, stop-bit = 1.0, flow-control = off12:10:04 : Activating device: OK12:10:04 : Chip ID: 0x482 12:10:04 : BootLoader protocol version: 3.112:10:04 : Response received from device: NACK12:10:05 : Error: Address not acknowledged: 0xFFFF12:10:06 : UPLOADING OPTION BYTES DATA ...12:10:06 : Bank : 0x0012:10:06 : Address : 0x4002204012:10:06 : Size : 48 Bytes12:10:07 : UPLOADING ...12:10:07 : Size : 1024 Bytes12:10:07 : Address : 0x800000012:10:07 : Read progress:12:10:08 : Data read successfully12:10

Hello ST Community,I'm currently facing a challenging issue with my STM32L476RET6 where I'm unable to erase a specific page in the flash memory. Despite the HAL_FLASHEx_Erase() function returning HAL_OK, indicating the erase operation was supposedly successful, the bytes at the specified memory location are not set to 0xFF as expected. I've confirmed this by checking the memory location with STM32CubeProgrammer.Environment:MCU: STM32L476RET6IDE: STM32CubeIDEOS: Windows 10 Here's the function where I'm encountering the issue: HAL_StatusTypeDef set_update_flag(void) { // Unlock the Flash to enable the flash control register access HAL_StatusTypeDef status = HAL_FLASH_Unlock(); if (status != HAL_OK) { // Unlock failed, handle accordingly return status; } // Define the page and bank for the erase operation FLASH_EraseInitTypeDef EraseInitStruct; uint32_t PageError = 0; EraseInitStruct.TypeErase = FLASH_TYPEERASE_PAGES; EraseInitStruct.Banks = FLASH_BANK_1; EraseInitS

I have the X-Nucleo-IHM07M1 siting on top of NUCLEO-F302R8 as shown attached. Trying to connect as follow? It is possible to connect 24V onto this board to drive 24V 3 phase motor?  

I am using the Stm32H747I-DISCO board for the x-cube-ai application, working with the FP-AI-VISION1 package. I already updated the package that suits the board version and read the user manual UM2611, according to the instructions I ran the code and turned the board on, but while trying to select one operating mode with the inbuilt joystick it is not working all the time. I thought there might be a delay in processing after waiting for a few minutes I noticed no change in the screen. Help me to figure out.

I have already spent hours trying to get the Arduino library working in my CubeIDE (1.12.0 IDE; latest STM32duino; Firmware F3 1.11.4). I set up all the include paths, and changed the arduino stuff, to point to the CubeIDE generated files. I had some issues, that the Serial was not declared, but this could be fixxed, when i changed my user_man file to *.cpp. But now it says " undefined reference to `setup' ".main.c:/* USER CODE END Header */ /* Includes ------------------------------------------------------------------*/ #include "main.h"   /* Private includes ----------------------------------------------------------*/ /* USER CODE BEGIN Includes */   #include "user_main.h"user_man.cpp:#include "user_main.h"   #include "stdio.h" #include "stm32f3xx_nucleo_32.h" #include <stdbool.h>   #include "arduino.h"   void setup(){    }   void loop(){ }user_main.h:extern void setup(); extern void loop();What has to be done in order to make it wor

Hello!! I'm a total newbie, so sorry for any mistakes, and I would like to ask for simple explanations as well.As title states, I would like to use a timer chosen from TIMx, not as an output on a pin, but rather for software only usage, to do an action periodically, instead of using a delay that would halt the rest of execution.I know which bus the timer is on, what is its frequency. I think I understand how to bring it down using prescaler and ARR. But from other settings in "Pinout & Configuration" tab- what should the channel be set as? Should anything else be changed from default in "Configuration"? Or in other tabs?And also, how should code look like? Which function (or maybe something else?) would be useful for such application?I am using CubeIDE version 1.10.1.

Hello everyone, can someone help me with LIS3DH Example and Library.any suggestion for library.Thank You 

Hey folks,I'm having issues with the RTC's calendar function while using BLE. I would like to timestamp recorded data using the calendar function of the RTC and then transmit that data over Bluetooth. However, when I enable the Bluetooth middleware in Cube, it forces the ASYNC and SYNC prescalers of the RTC to predetermined values of 0xF and 0x7FFF, respectively. See image.Is it possible to use the calendar function while using BLE? If so, how?Thus far I found the following in app_conf.h (which is not very encouraging...) :#define CFG_RTCCLK_DIVIDER_CONF 0 #if (CFG_RTCCLK_DIVIDER_CONF == 0) /** * Custom configuration * It does not support 1Hz calendar * It divides the RTC CLK by 16 */ #define CFG_RTCCLK_DIV (16) #define CFG_RTC_WUCKSEL_DIVIDER (0) #define CFG_RTC_ASYNCH_PRESCALER (CFG_RTCCLK_DIV - 1) #define CFG_RTC_SYNCH_PRESCALER (0x7FFF)Is there a way to make the two work alongside each other?

i've installed versions of STM32CubeProgrammer on my windows 10 PC as well as my MAC....i'm following the instructions in um2269 (section 8) on updating firmware, but see a message saying "No DFU detected" under the USB configuration panel....  selecting Connect fails at that point....on windows, the device manager seems to identify a 'Power Shield (Virtual ComPort in FS Mode)' as well as a new 'USB Serial Device' when i plug in my board....  but there is a warning sign that ultmately tells me that windows can't find a driver....  drivers were definitely installed along with CubeProgrammer; and i've run some .bat file under the Drivers folder....do i need to do anything with my (brand new) board???  if i move the sliding jumper to the 'Syst' position *BEFORE* plugging in the board, it doesn't even power up.... 

Hello,I have set the BR bit in CR1 to 0 with the expectation of obtaining an 8MHz clock frequency. However, I am encountering an actual frequency of approximately 1.042MHz. Does anyone have an explanation for this issue, or should I consider implementing any calibration procedure for the clock? Best regards,

Using STM32CubeIDE (v1.14.0) with STM32F042F6P7 (TSSOP 20) to configure CAN pins on custom board. However the CAN peripheral is grayed-out when I open the IOC file in STM32CubeIDE. For pin assignments, PB8 is available for CAN rx but CAN tx is not show for any other pin. How do I access alternate pins for the CAN peripheral? Reference manual says PA12 should be available as alternate for CAN tx; and PA11 should be available as alternate for CAN rx.

dear ST / reader,our application uses the STM32H743. We need a unique serial number to be stored in this micro, in non-volatile memory, to uniquely identify each board. There’s no on-board EEPROM, so we were wondering if this device includes any internal unique number of its own that can be accessed and which could then be used for this purpose when we found the following …The “Unique device ID register (96 bits)�? which is “unique for any device and in any context�?. Does this mean the value will be different in each and every STM32H743, or all STM32H743s have the same number ?What is the procedure to read this value, please ?

Hi,I have question for ST25R3916BI am only using the ST25R3916B chip on its own. I have successfully set up SPI communication for reading and writing. Now, I need to understand how I can read from ST25TV02K data.

I am working off of Custom Hardware using the ST25R95 and I can read tags but I am trying to keep the device into IDLE mode but can't get it to work.I have ran tag detect calibration without a tag in the field and came up with a result of 0x5C. (See attached Traces from boot)I used 0x5C as the base for IDLE mode and use the +/-0x08 to setup the thresholds.Using 0x5C, the device keeps telling me that there is a tag and starts to read a tag, goes into IDLE and repeats without a tag in the field. (See attached Traces from boot).Do you have any ideas why this will not stay in IDLE?

Hi,we are currently porting a custom dunfell distro from STM32MP151A to STM32MP151C.We followed the guides related to creating our own machine by generating the device tree in CubeMX and succeeded in building it correctly.https://wiki.st.com/stm32mpu/index.php/How_to_create_your_own_machineAttempting to flash the board crashes in writing the first partition related to the file "arm-trusted-firmware/tf-a-stm32mp151c-my-project-mx-usb.stm32". What could be the cause?Attached my conf/machine/<machine>.conf file (extended extension to .txt for uploading)I would like to thank you for any help.

Hello,I'm trying to use DMA with an Usart to receive incoming data in a circular buffer. Basically this is my code for configuration using UART5. I can send data, so i assume, that port und clock configuration is correct. When receiving data, NDTR is couting down but there is no data copied into the buffer M0AR. Uart5 uses DMA1 Stream0, Channel 4. FIFOs are not used.When i switch to polling receiving without dma, everything works. What can be the issue?  dma = DMA1_Stream0; dma->CR &= ~DMA_SxCR_EN; dma->CR |= 4 << DMA_SxCR_CHSEL_Pos; dma->PAR = (uint32_t)&oConfig.oUSART->DR; dma->M0AR = (uint32_t)&buf_rx[0]; dma->NDTR = BUFFER_SIZE; dma->CR |= DMA_SxCR_PL_1; dma->CR |= DMA_SxCR_PL_0; dma->CR |= DMA_SxCR_MINC; dma->CR |= DMA_SxCR_CIRC; dma->CR |= DMA_SxCR_EN; oConfig.oUSART->CR1 &= ~USART_CR1_UE; oConfig.oUSART->CR3 |= USART_CR3_DMAR; oConfig.oUSART->CR1 = USART_CR1_TE | USART_CR1_RE; oConfig.oUSART-&

I would like to know if the M24LR 64 ER memory using NFC already has support for IOsxx. I am trying to read and write data to this memory but without success, I receive errors 100 and 103.

Hi ,I am new to use STM32Cube IDE.I am using the STM32Cube IDE for developing the applcation related to STM32H750B-DK Board with STM32H750XBH6 MCU.When I am trying to debug my application through STlink-V3 .I am not able to debug the application .For you reference I posting the snapshot .please have a look and response ASAP.  

The datasheet suggest its suitable for SMPS / lighting power supplies. Not clear if they can be used for the inductive load at the output of the hotswap controller.

I want to flash and debug using SPC5-UDESTK 5.02.04 on to the board SPC5746CBMKU6. This controller configuration is not given in the tool. So I have created new configuration for this board. Now I have tried to connect to target board. But it is failing to establish connection. Connection and power supply is good(Tool LED glows). May be problem with target configuration. Attaching failed report and new target configuration file(in .txt, as .cfg is not supported here). Kindly provide the target configuration file for SPC5746CBMKU6, if you have. Or suggest edits in current file.
