Hello, I use an AT32F403A MCU to connect LSM6DS3 IMU via SPI 4-wire, then I read the WHO_AM_I register at 0x0F. According to the datasheet, the return value should be 0x69, but the chip returned 0x44. Then I repowered the board, and the value seemed to change to 0x7F. Then I read the Acc and Gyro data. From the logic analyzer, there seem to be some abnormal glitches, which looks like some connection problems, but I checked the wiring and I can't find the problem. Can somebody help me figure out the problem? Thank you.

Is there a way to find the RF output power using the ST25R3916 without measuring it externally? I don't need an exact value. The product selector says the nominal output power is 1600 mW. However, at a max of 3 Vpp and 150 mA input current (measured via power profiler), that's 450 mW not including losses. I know that the output power can be adjusted via the d_res register, which I do, but that's only to aim for the target amplitude. Is there something else I can look at here?

Hi, It works, apparently a different microSd card works. however, it is strange that, DATALOG2 could write into the card. May i know how shall i perform sd card format function or what to fill up in the function?   Follow-up of the the topic below: Solved: Re: Standalone FileX SDIO SD Card Initializing err... - STMicroelectronics Community  

Hello there, I was working on TouchGFX and when i tried to build my code i got error: no declaration matches 'bool TouchGFXHAL::blockCopy(void*, const void*, uint32_t) and same for endFrame and beginFrame. But i couldn't solve the problem.  Here is the part from TouchGFXHAL.cpp file.bool TouchGFXHAL::blockCopy(void* RESTRICT dest, const void* RESTRICT src, uint32_t numBytes){return TouchGFXGeneratedHAL::blockCopy(dest, src, numBytes);}/*** Configures the interrupts relevant for TouchGFX.

Hi,I'm trying to use the least possible threshold for IIS2DLPC tap detection.Is it achieved by setting TAP_THSX[4:0] as 00000b or 00001b?I see that 1 LSB corresponds to FS/32. Does 00000b means the threshold is 0g or some fixed value?If the threshold is 0g, then the sensor should not detect any taps, as the acceleration values cannot fall below the threhold value. right?Thanks in advance

I am using the stm32wb55rev6 boards for the ble.What should be the configuration to commuicate between the 2 stm32wb55rev6 boards?i am using the trasparent mode in 1 stm32wb55rev6 board and what should be the configuration on the other board to scan and connect the other board.if there is any document related to this please share here.  

There is no test.txt file in my USB drive after the example is run.The board sends this log**** USB OTG HS Dual_Class Host **** USB Host library started. Starting Application Connect your HID or MSC Device USB Device Enumeration FailureTried to attach the USB drive to both USB connectors.The last message is sent about 1.5s after the previous ones.Where can be an issue?

Hi, The mbedTLS v3.6.x is LTS version and released for quite long time. Do you have plan to upgrade mbedTLS to v3.6.x with MX? If not, customer shall manually integrate/upgrade the mbedTLS to v3.6.x. Could you please give me a guideline to do that. Thanks!

Hello, I'm currently testing a bootloader-XIP application architecture on a NUCLEO-H7S3L8 board. The MRAM (XSPI2) test works perfectly in the bootloader, but when I move the same code to the XIP application, the system hangs during XSPI2 initialization. I would appreciate any advice on this issue. System Environment MCU: STM32H7S3L8 Board: NUCLEO-H7S3L8 IDE: STM32CubeIDE v1.19.0 Firmware: STM32Cube_FW_H7RS_V1.2.0 Project Goal and Progress I have successfully completed all communication mode tests for the MRAM (XSPI2) in the bootloader (exercise_Boot). The bootloader runs from internal flash, and through mram_spi_test.c, it has fully tested the MRAM connected to XSPI2 in all SDR/DDR and SPI/DSPI/QSPI modes, confirming perfect opera

My Feedback on STM32WB Series Flash ArchitectureDear STMicroelectronics Team,As an experienced developer working  with the STM32WB series, I must voice a critical concern about its current flash memory architecture.By placing both the Cortex‑M4 application and the Cortex‑M0+ wireless stack into a single shared internal flash, divided only by secure boundaries, you have created avoidable complexity and limitations for developers and end‑users alike. This design forces us to contend with:Hard‑coded secure boundaries (SFSA/SBRV) and OB flags (DDS, C2OPT) that can only be altered via FUS or System Memory, making recovery unnecessarily difficult.Loss of usable program space for the M4 when the wireless stack is present, even if the reserved region is unused.Risk of total application downtime when the

Hi all,I'm working with an rak3171 build with an STM32WLE5CC, I've write a python script for flashing my firmware over uart using usart ST bootloder, everything works well, but when flash is done, I'd like to reset my bord for running the new firmware.I've use this ST AN NOTE  and if you look at page 18, ST explain GO command, I'm trying to use but without success, my board never reset, so my question is, am I understand well, if I use GO command should I'm able to reset my board? Is there a ST example somewhere any helps will be good :) EDIT: I'ma able to send GO command and FW addr, bootloader ACK me (gor 0x21 and addr, but after that nothing happen, my firmware doesn't run..thanks

Hi,Can someone help me how to use MbedTLS to my TCP Client Example. I haven't worked before . please tell me step by step. How can I proceed.I'm attaching the source code for the reference. Thanks,Harshitha R

We have a design on an ST32G431 based on the B-G431B-ESC eval board that we are trying to migrate to an STSPIN32G4. However the tools appear to not let us set up the same 3-shunt, internal op-amp, internal PGA, differential configuration on STSPIN. There seems to be a problem with the 3rd op-amp and supporting differential mode.All works fine with the B-G431B-ESC based design but if I create a board based on STSPIN the workbench generates errors.RCSConnect: ThreeShunt_RawCurrents_Differential_InternalGain Global NO OPAMP for Phase VWe see the same errors if we load the EVLSPIN32G4-ACT board in the workbench and hit "go to summary". The difference with the EVL board is that it has a number of different variants so will still load but doesn't offer the "3-shunt + differential" option even though it is in the board config file.The pins appear to be available and as far as we understand it the

Hi everyone,I am trying to generate sinewave using PWM mode of microcontroller.I am using Discovery Board having STM32F407 microcontroller. System clock and Timer clock are of 8MhzI am using two timers Timer1 for High Frequency switching (500Hz) and Timer2 for Low Frequency switching (50Hz).waveforms I am getting are OK but there is one issue, after every 7 cycles I am getting an extra PWM sample in my output.I don't know why it is so. I am attaching image of the output and code. may be there is a minor mistake which I am doing but not sure. can you guys let me know if there is an issue 

Hello and good day. I am doing a project of running a motor using 6-Step with Hall Sensor.I am facing an Overcurrent issue while using Motor Pilot V6.4 in 6-Step + Hall Sensor mode. In MC Workbench, the current limit is set to 15A but the Nominal Current is shown as 2.16A in the Motor Pilot GUI. No matter what I do in MC Workbench, the Nominal Current doesn't change and always shows as 2.16A. Consequently, I can't start the motor as it there is always Over Current fault as the motor needs more than 2.16 to start.I know that it's not a limitation of my Power Board as it is rated at 20A.

hello , T。T     I’m developing a GUI using TouchGFX on the STM32F469I-DISCO board.In the handleTickEvent() function, I add 5 points to a dynamic data graph each time it is called. However, when doing this, the frequency of handleTickEvent() drops significantly, and the display performance becomes very poor.In comparison, an older project based on the demo uses MIPI DSI in command mode and configures LTDC as 480×200×4, and it performs noticeably better than my current setup where LTDC is configured as 480×800 and DSI is set to video mode.The scan is 480 * 800 .

i am usng stm32wb55rev6 microcontroller for my project. I updated the firmware upgrade service to the latest version of the v2.1.0.0 and updated the stack version to the latest version of v1.23.0.3.Still i am not able to connect to the stm32cube monitor rf. Is there any thing i have to update to connect to the rf?

Hi,  I am working in STM32G491, currently working on MCU firmware upgrade part. I have a doubt regarding the output pins. Currently we have SET 2 GPIOs to high. That is power enable for another device say A. From another external device B, it is controlling bootpin and nrst pin.  My doubt is if I make mcu to bootmode does that GPIO output value changes? The situatuion is during device running, I make 2 gpio high. From another device mcu got entered to bootmode. Does the output pin change the high value?

The Cube-AZRTOS bundles cmsis_os2.c implementation has potential NULL pointer dereferences.  There are many lines of the form:if (( attr->cm_mem == NULL) || (attr == NULL))in code that attempts to recover and de-allocate memory from a "create" call that failed.  The order of comparisons should be reversed:if ((attr == NULL) || (attr->cb_mem == NULL))This happens for different structure members, not just the cb_mem.I've checked the F4 version 1.1 ZIP file and github repo, as well as the github H7 repo and they both have this issue.  I suspect all versions do.

Hello, Using the latest CubeMX 6.15.0 I was generating ThreadX for Secure - Non Secure Project (for STM32N6 - Cortex_M55). This did not add file : "\Middlewares\ST\threadx\ports\cortex_M55\gnu\src\txe_thread_secure_stack_allocate.c" and so is not added in to the CubeIDE project. Where as it's counterpart - "\Middlewares\ST\threadx\ports\cortex_M55\gnu\src\txe_thread_secure_stack_free.c" is getting generated and added to the project. Also, compiler includes like "/Secure_nsclib" , "/Drivers/CMSIS/Include" did not get added into the Compiler Include Paths in the CubeIDE project that this CubeMX generates. 

VL53L1CB必须配置其 ROI（感兴趣区域）以定义要读取的“单元格”网格。如果不设置 ROI，则只能获得一个合并的距离值，该值将来自所有 SPAD 的信号求和，并且您将无法获取每个子区域的解析数据。上述说法正确吗？Please note that the official forum language it English - see the Community Terms & Conditions.Google Translate:The VL53L1CB must have its ROI (Region of Interest) configured to define the grid of "cells" to be read. Without setting the ROI, you will only get a single combined distance value that sums the signals from all SPADs, and you will not be able to obtain resolved data for each sub-region. Is this correct?

Hi there,On a STM32WB55RG, I would like to write a routine in my firmware to upgrade the wireless firmware through the FUS mailbox.I'm able to exchange request/response through the mailbox, for instance, at startup FUS_GET_STATE returns FUS_STATE_IDLE, no error. Cool.I load a wireless firmware at the address indicated in the Release Notes (for instance stm32wb5x_BLE_HCILayer_fw.bin at 0x080E1000), however when I run FUS_FW_UPGRADE, the chip reset as expected and right after this reset, theFUS state value is 0x10; FUS_STATE_FW_UPGRD_ONGOING (according to AN5185)FUS state error value is 0x06; FUS_IMAGE_ERSERROR (still according to AN5185)Having no clue about the routine inside FUS firmware, could you help me to identify what's the root cause behind that. Btw, I have the same issue if I want to upgrade the FUS firmware itself.While
