As shown on the website below, the Arc Fault Circuit Interrupter (AFCI) solution is introduced as an Edge AI use case.https://www.st.com/content/st_com/en/st-edge-ai-suite/case-studies/direct-current-arc-faults-detection.htmlFor hardware development reference, would it be possible to purchase the development board shown on the page?It would also be helpful if you could share the schematic and BOM of the PCB.

I am running the pre-compiled "object Detection" files on the STM32N6570-DK and am in the process of trying to generate my own STM32CubeMX setup project for the fsbl.I am having difficulty setting up the numerous options for the DCMIPP for this project and have read a lot of the recommended documentation but there does not seem to be any specific details for interfacing to the MB1854 camera module on this kit.From what I can figure out the "Object Detection" demo uses pipe1 for the display and pipe2 for the NPU processing but I am lost as to what settings to use for DCMIPP in STM32CubeMX.I need to know what pipe formats, data types etc are needed for each of the pipe1 and pipe2 settingsCan anyone please help me with this?

Was trying to figure out an issue I was having with the SWDCLK pin, and realized there was a difference between the STLink V3-MINIE and the V3-SET.When idle (either just plugged into a computer, or after programming), the SWDCLK idles high on the MINIE, while on the SET it idles low.Is this an intentional difference? Is there any way to make the SWDCLK idle low on the MINIE as well?

Dear All,I generated the code after configuring the STM32MP257F on CubeMX, however, after opening the generated project on STMCubeIDE and building it yield errors. I don't get why.

Hi everyone,I am a beginner working with the VL53L1X sensor on an STM32F103C8T6 using the STSW-IMG009 (Ultra Lite Driver). I am trying to implement a calibration routine, but I am encountering two specific compilation errors inside my VL53L1X_calibration.c file:The errors:1. 'VL53L1X_ERROR_TIMEOUT' undeclared (first use in this function); did you mean 'HAL_DMA_ERROR_TIMEOUT'?2. implicit declaration of function 'VL53L1_WaitMs' [-Wimplicit-function-declaration]I have checked the driver files but cannot find their declarations.I have not changed any of the driver files. Am I missing something? Any help is appreciated. Thank you!

Dear community,I am looking for help to have TFM ported for nucleo_u385rg_q so that I can build the tfm secure and non secure images and do a secure boot on this board. The closest board is b_u585i_iot02a which is a stm32u5 variant. But there are many low level code required for this in trusted-firmware-m repo. Is there a work done by someone that I can use for my work? Any pointers as to how to accomplish this. Thanks in advance for your support.

I'm stuck at trying to make motion_fx call MotionFX_LoadMagCalFromNVM and MotionFX_SaveMagCalInNVM - a problem which is mentioned already in link1 and link2 but to which actually there is no working solution (the rest of the motion_fx seems to work without any issue). I implemented the functions as below, but already when compiling, they get optimised out and end up being discarded - hence the motion_fx library never calls them, in contrary to what UM2220 suggests. My code does actively call MotionFX_MagCal_init(MFX_MAGCAL_SAMPLE_PERIOD_MS, 1); and MotionFX_MagCal_init(MFX_MAGCAL_SAMPLE_PERIOD_MS, 0); which as per UM2220 should trigger the call of the NVM functions. Here is my implementation:volatile int deb_load_nvm_called = 0; volatile int deb_save_nvm_called = 0; char MotionFX_LoadMagCalFromNVM(unsigned short int dataSize, unsigned int *data) { Message_Logger("hi from save %i", deb_load_nvm_called); deb_load_nvm_called++; nvm_status_t s = NVM

Hello,I have a custom PCB that uses an STM32L4R9 controller and runs two applications. One is a bootloader and other is the actual app. The files are called boot.hex and app.hex.The boards are made via a vendor and programmed with these files during ICT. We use ST Link programmer and SWD connection to program the devices.I use the ST Link V2 Utility CLI to do this.A batch file is made that runs all the commands that program the option bytes, erase chip, and programs the above files.The problem I am facing is, the batch file fails to execute the first time. It fails after the option bytes step. The second time however, it always executes and programs the applications successfully.I did wonder whether this is because the Read Out protection for STM32L4R is set to 1 from the factory? But again, I tried to revert the option bytes to factory after which I cannot read the flash memory again before setting it back to Level 0.But if I connect a new and unprogrammed board to the ST Link V2 Util

Greetings!I am trying to establish a connection between STM32F439IIH6 (Slave) and a customize board (Master) through SPI DMA application. The customize board has its own built-in driver with SPI application. The communication between STM32F4 and customize board eventually broke down after few thousands of cycles. Through some investigation, I found out that the SPI_WaitOnFlagUntilTimeout() hangs inside SPI_DMATransmitReceiveCplt(). It sutcks inside the else statement of SPI_WaitOnFlagUntilTimeout(). The clock used in customize board (Master) is 80Mhz with clock division 4/** * @brief This function handles SPI Communication Timeout. * @PAram hspi: pointer to a SPI_HandleTypeDef structure that contains * the configuration information for SPI module. * @retval HAL status */ static HAL_StatusTypeDef SPI_WaitOnFlagUntilTimeout(SPI_HandleTypeDef *hspi, uint32_t Flag, FlagStatus Status, uint32_t Timeout) { uint32_t tickstart = 0; /* Get tick */ tickstart =

Hello,WORKING ON : STM32H753I am looking to implement a jump from one application to another on an STM32H7 (Cortex-M7), so that the new application starts as if the microcontroller had just been reset: MSP initialized, VTOR set, caches (and MPU maybe?) correctly managed, peripherals reset, SysTick and IRQs disabled.Knowing that my APP1 is a custom bootloader at address 0x08000000 and my APP2 is my main application with lots of peripherals, timers, DMA, etc. at address 0x08020000.I tried many sequences to make a jump without crashing.My jump from APP2 (app) to APP1 (bootloader) seems to work without bugs:  //disable interrupts __disable_irq(); //disable Systick SysTick->CTRL = 0; SysTick->LOAD = 0; SysTick->VAL = 0; //deinit HAL_RCC_DeInit(); HAL_DeInit(); // __enable_irq(); // vide cache SCB_DisableICache(); SCB_DisableDCache(); __DSB(); __ISB(); // je définis ma table des vecteurs au début de mon IAP donc à IAP_ADRESS (0x08000000), ave

Hello everyone. I am running into a USB Host <--> Device connectivity issue. I have 2 STM32L496 MCUs, one as Host and other as Device. I cannot get the CDC connectivity to work for some reason. The connections are as follows: D+ <> D+, D- <>D-, GND<>GND.I have VBUS, SOF and NOE disabled. CubeMX forces to set Drive_VBUS as well over a GPIO, however, I am not using that in my circuit. Even though it is a recommendation in USB connectivity in AN4879, I believe it is possible for a simple connectivity without it as well. Would this be a wrong assumption (and hence the culprit)? As a connection stability, I tested both MCUs individually as Devices, connecting to my PC and it sent data over USB just fine. The attached code has NucleoL496 as the host. Would appreciate your support.

We are pursuing UL3141 for Power Control Systems (PCS), this includes UL991 which is the Standard for Tests for Safety-Related Controls Employing Solid-State Devices, and it requires a critical component analysis.In our particular design, the STPM34 is a critical component used in our PCS. To avoid hardware redesign to add sensor redundancy or a self-test circuit, we can use a "computational method" by considering component FIT data.Typically we expect FIT data on the order of 10^6 or 10^9 hours.Do you have FIT data available for the STPM34, that is measured to an applicable standard?Does STMicro have critical component analysis data available for the STPM34?Does STMicro have internal resources to support customers with critical component analysis?Kind regards,Bryn

On the STM32MP135F-DK, is the 4.3" LCD module physically removable? Or is CN16 accessible without removing the LCD?

Are there STM32CubeMX files for the example projects in STM32Cube_FW_MP2?  It would really help understand peripheral configuration.  Specifically the .ioc file for the OpenAMP example project used in this tutorial.I am trying to better understand STM32CubeMX peripheral setup, especially in regard to how each peripheral can be selected for each core in secure or non secure mode.  And how that interacts with the Linux device tree.

Hello guys, I started a project using STM32C552RET6 and STM32CubeIDE. When I use the autocomplete feature to select a HAL function, I can’t find it. I have to type the function manually.Does anyone know how I can fix this problem?Thanks for your help.

Hi everyone, I'm working on a prototype, which is using a PM8805 to classify connected PoE types. However we are running into an issue, where neither T0, T1 or T2 are giving us any signals (giving always 1 on their open drain signals, making .the LEDs stay off). Suspecting an issue with our prototype, we went on to get a STEVAL-POE001V1, which is showing the same scenario: With our different PoE, PoE+ and PoE++ injectors (Both Ubiquity and TP-Link brand), the T0, T1 and T2 LEDs are remaining off. The PGD LED is however on in those tests. We tested with and without a load on the output (for example 5kOhm) to prevent the injectors going into standby mode. We checked and according to datasheets the TP-Link TL-POE160S is an active 802.3af/at compliant injector. Is my understanding correct? With the CLS 1 resistor at 36.5Ohm and the CLS2 resistor at 51.1Ohm, the T0, T1 and T2 signals should, as an example, be 0, 1, 1 respectively for a

Hi,   I am implementing a Dual Active Bridge (DAB) DC-DC converter on an STM32L476RG Nucleo board. The goal is to generate 8 complementary PWM signals using TIM1 (Bridge 1) and TIM8 (Bridge 2), both at 5 kHz with 50% duty cycle, and to control the power transfer by adjusting the phase shift between the two timers.   The phase shift must be adjustable at runtime (via button, potentiometer, or PID controller) without affecting the 50% duty cycle.   I tried three synchronization approaches, all of which failed:   1. Reset Mode (SMS=100): TIM1 sends a TRGO at the end of each period. TIM8 receives it and resets CNT to 0, which cancels any preloaded phase offset every 200 µs. The phase shift cannot be maintained.   2. Trigger Mode (SMS=110): TIM8 starts on the first TRGO then runs freely. The initial phase is correct but there is no ongoing synchronization, which could cause drift over time.   3. CCR1 as TRGO source (MMS=011): Using CCR1 to time the trigger woul

I have enabled USB with the following settings:Following USB middleware is enabled like so:In the linker script I have moved everything from DTCMRAM to RAM.Additional section is specified like so.dma_buffer : { *(.dma_buffer) } >RAM_D2And used like so:/** Received data over USB are stored in this buffer */ __attribute__((section(".dma_buffer"))) uint8_t UserRxBufferHS[APP_RX_DATA_SIZE]; /** Data to send over USB CDC are stored in this buffer */ __attribute__((section(".dma_buffer"))) uint8_t UserTxBufferHS[APP_TX_DATA_SIZE]; At this point USB device enumerates but looks like no descriptors are transferred to the host.I also tried to enable MPU like so:But that did not do the trick.However, when RAM region base address (0x24000000) is used instead of RAM_D2 (0x30000000) for MPU, device enumerates correctly:and there is no need for:__attribute__((section(".dma_buffer")))on rx and tx buffers anymore.Now the question. How to correctly place only the USB related stuff to

Hi.I'm using an STM32G051 and would like to use 12 ADC channels which are not sequential. I have thus set up the ADC for 'sequencer set to not fully configurable' as show below:Ignore for the moment that IN9 is red, I think I was trying something with one of the comparators to see if that helped.I'm using the DMA to kick off a new conversion and the callback reports back raw values which I print out as seen below.If I enable IN0, IN9 or IN10 then I get bad data from the ADC (possibly mixed up channels) as seen below where the VREF+ is being reoprted as over 5V when it should be 3.3V.VREF+: 5362 mV.CPU Temperature (STM32): 1870.0 °C.Sample Temperature: 0.0 °C.LED feedback current: 0 mV.raw vref ADC value: 0x3a5.raw DET0 ADC value: 0x184.raw DET1 ADC value: 0xfff.raw DET2 ADC value: 0xffe.raw DET3 ADC value: 0xffd.raw DET4 ADC value: 0xfff.raw DET5 ADC value: 0xffe.raw DET6 ADC value: 0x5e4.raw STM32 temp value: 0xffe.raw LED feedback current value: 0x00e.If I disable IN8, IN9 and IN10 (

Hi,  I am using STM32WBA55G-DK1 as a BLE TMAP Peripheral, I have a transmitter, which is transmitting 4 channels/subgroups of data.

I am working with the STM32WB5MMG and implementing firmware updates using OTA. For testing, I am using the ST BLE Sensor Android application. What I Tested I first tested OTA using the example projects available in the STM32CubeWB firmware package: Heartrate_ota P2PServer_ota Both examples work correctly. I can: Flash the example firmware Connect using the ST BLE Sensor app Upload another firmware via OTA successfully My Custom Firmware After verifying OTA with the examples, I created my own firmware that includes: Custom BLE service Custom characteristics Custom UUIDs and device name When I upload this custom firmware via OTA from the example firmware, the update completes successfully and the device runs my application correctly. Problem After my custom firmware starts running: The device no longer appears in the ST BLE Sensor app as OTA-capable. I cannot upload another firmware via OTA. The device does not advertise as an OTA device like the Heartrate_ota
