I need to use in our application three phase power supply any of the two phase present power supply should work or with respect neutral also work if any of one phase present.  required for voltage monitoring three phase or sequence detector. any reference please provide voltage and sequence detection.capacitve power supply. 

I am performing a thermal analysis with component M24C04-DRMF3TG/K TSSOP8 package.  The datasheet does not contain any of the typical thermal resistance information:  thetaJA, thetaJC_bottom, thetaJC_top.  Is this information available?   Thanks, Andrea

Hi,I just wanted to check if is it dangerous to move the isr_vector inside the text section like this:.text :{. = ALIGN(4);KEEP(*(.isr_vector)). = ALIGN(4);FILL(0x00000000);. = ALIGN(4);*(.text) /* .text sections (code) */*(.text*)*(.glue_7) /* glue arm to thumb code */*(.glue_7t) /* glue thumb to arm code */*(.eh_frame)KEEP (*(.init))KEEP (*(.fini)). = ALIGN(4);_etext = .; /* define a global symbols at end of code */} >FLASHI implemented a CRC32 integrity check and it doesn't work because the gap between the isr_vector and text section is always Fs when I debug with the CubeIDE, but if I download the .elf with CubeProgrammer, the gap is filled with 0s, and in that case it works.TY for your help.

Hello, everyone.Can the STM32F407VE encrypt multi-byte messages to maintain the confidentiality of messages between the host and client (stm32)? If so, what type of encryption can be run on this processor?Thank you:)

Edited to place the image in the post - for easier viewing.Hello, This is my first time posting. I am trying to find the P/N from the part's marking. If you know it, please let me know.Engraving: GP229Guess: Schottky barrier diode STPS2L60 - 2A, 60V. Is that correct...?If you have any information, please let me know. Thank you.  

I am working on an STM32H563 project with a custom bootloader and two application slots (APP1 / APP2).This is my memory layoutBootloader: 0x08000000APP1: 0x08022000APP2: 0x0806C000The bootloader is already deployed in the field and cannot be modified.The bootloader jump sequence is standard:Validate applicationSet SCB->VTOR = APPx_START_ADDRESSLoad MSP from APPx_START_ADDRESSJump to reset handler at APPx_START_ADDRESS + 4 This works perfectly when I build the application the “manual” way:Manually change FLASH ORIGIN in the application linker script to 0x08022000Manually change VECT_TAB_OFFSET in system_stm32h5xx.cThen i ReBuild → flash → bootloader jumps and application runs correctly.I would like to automate this process using cmake , without manually editing the linker script and system_stm32h5xx.cSo I implemented:A parameterized linker script template (STM32H563xx_FLASH.ld.in)CMake configure_file() to generate slot-specific linker scriptsCMake target_compile_definitions() to

Hallo everyone,Before I encountered a bug in an USB_OTG_FS library function (see previous post), I struggled to find out when the function  'CDC_Transmit_FS(uint8_t* Buf, uint16_t Len)' has finished, meaning the content of the 'Buf' argument is completely transmitted.After a thorough search through the various sources and the Reference manual RM068, I concluded the Register DOETMSK has a bit XFRCM that should fire an interrupt in case the the transmission has finished. I assume the common interrupt function ' HAL_PCD_IRQHandler(&hpcd_USB_OTG_FS)' will deduce that function 'CDC_TransmitCplt_FS(.......)' should be fired when the XFRCM creates an interrupt.Despite my efforts I could not find a way to:   a) find out if my assumptions above are complete and/or correct   b) how to handle the registers for the USB_OTG_FS device. In the SWF column of the debugger I saw 4 groups of OTG registers, but never found a way to access them in my code. And the complexity of

Hi everyone, I am trying to bring up the DP83867 with RGMII on the STM32MP131DAG7. However I am getting the following error:[ 18.253959] stm32-dwmac 5800a000.ethernet end0: renamed from eth0 [ 23.695184] stm32-dwmac 5800a000.ethernet end0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 23.756147] stm32-dwmac 5800a000.ethernet end0: PHY [stmmac-0:00] driver [TI DP83867] (irq=POLL) [ 24.764629] stm32-dwmac 5800a000.ethernet: Failed to reset the dma [ 24.769435] stm32-dwmac 5800a000.ethernet end0: stmmac_hw_setup: DMA engine initialization failed [ 24.808705] stm32-dwmac 5800a000.ethernet end0: __stmmac_open: Hw setup failed I saw this is typically due to the 125MHz clock not being generated.

Hi All,Please could somebody offer some words of wisdom to resolve the apparent ambiguity in the C0 datasheet, which on the one hand states that once IWDG is started it cannot be stopped, yet on the other hand offers a IWDG_STDBY bit in the OPTION registers to allow it to be stopped during Standby. The latter does not appear to work, since my system wakes itself after the prescribed watchdog period, so it seems like the first statement is the correct one.Since the watchdog definitely CAN be stopped during debug if DBG_IWDG_STOP is set, there is clearly a mechanism by which it can be stopped under certain circumstances, suggesting the first statement is not correct, or at best is not the whole story.If it can't be stopped in Standby....a) what's the point of the IWDG_STDBY bit?b) how can I keep my system in Standby? I must have the watchdog running while awake. Many thanks

Hello,I stumbled over a weird problem when trying to debug Memory Protection Unit (MPU) settings which I want to document here in case any other people have the same issue:SetupThe used MCU is a STM32H7S3L8H6 on a STM32H7Rx/7Sx Nucleo-144 board (MB1737)Core frequency is 400 MHz.Enabling or disabling the cache has no impact on the problem.The code is executed from the internal flash, the stack and variables are placed on the DTCM.The debugger which I use is a Lauterbach CombiProbe 2 attached to a Power Debug Pro Ethernet. TRACE32 PowerView software version is R.2025.09.000186004.The executed software is a custom operating system which uses the MPU to prevent user-space threads from accessing memory regions not allocated to the threads. For this, one MPU region each is used for ROM, RAM and stack. The MPU is activated before the thread is executed and disabled afterwards. The background region is active.I have not tried to reproduce the error by using similar MCUs or other debu

Hi,Are there plans for supporting the new ST 4G NB=IOT modem ST87M01 in the X-CUVE_CELLULAR software stack?Thanks, Hans.

Hai All!I use 2 pieces of APS25608N PSRAM on OSPI bus with memory mapped mode. The MCU run at 1.8V, 160MHz system clock. Previously, I used APS12808N at 80MHz and 3.3V VDD without any issues.Currently, the PSRAMs run at 50MHz, but need to speed up to 100 or 160MHz.I thought the aps256's default settings should be good up to 100MHz, but they weren't.My working settings at 50MHz was ( relevant source in attachment): MR0: Fix type latency, latency code 5, and full strength (25 ohms).MR8: 32Byte Warp burst and without crossing.OSPI settings are:Dummy cycles:  Read = 8, Write = 4 hospi->Init.FifoThreshold = 4; hospi->Init.DualQuad = HAL_OSPI_DUALQUAD_DISABLE; hospi->Init.MemoryType = HAL_OSPI_MEMTYPE_APMEMORY; hospi->Init.DeviceSize = 25; hospi->Init.ChipSelectHighTime = 2; hospi->Init.FreeRunningClock = HAL_OSPI_FREERUNCLK_DISABLE; hospi->Init.ClockMode = HAL_OSPI_CLOCK_MODE_0; hospi->Init.WrapSize = HAL_OSPI_WRAP_NOT_SUPPORTED; hospi->Init

Hello, Regarding current implementation of wrapper timers in st87ec library, we have a few questions:Is it fine to change implementation of tick resolution? Lets say if we have tick every 1 microsecond, if we change implementation of wrapper timer by multiplying by 1000, will it affect any other parts of library?Is there a plan to change implementation to interrupt driven for low power applications?What is expected longest timeout which requires waking up every 1ms?Is there sequence to put st87 to PSM? Best regards,Kamil.

Hello,I have a issue with my STM32U5G9. It does not go into standby or shutdown mode. I want to achieve a wake-up by the power button of my device. The powerbutton is connected to PWR_WKUP6 (pin PB5). The button has a 100k pull-up. I verified the voltage levels with a scope (3.3V --> 0V).I checked with the examples in the STM32CubeU5 Github repo. This my code: void LowPower::EnterStandbyMode(void) { PrepareForLowPower(); __disable_irq(); for(int i = WWDG_IRQn; i <= JPEG_IRQn; i++) { NVIC_ClearPendingIRQ((IRQn_Type)i); } /* Enable WakeUp Pin PWR_WAKEUP_PIN6 connected to PB.5 */ HAL_PWR_EnableWakeUpPin(PWR_WAKEUP_PIN6_LOW_0); /* Clear all related wakeup flags*/ __HAL_PWR_CLEAR_FLAG(PWR_WAKEUP_FLAG6); HAL_DBGMCU_DisableDBGStandbyMode(); /* Enter the Standby mode */ HAL_PWR_EnterSTANDBYMode(); // If entry fails (e.g., if a debugger is attached), reset the system NVIC_SystemReset(); } I have a similar function for shutdown mode. I tried to clear all inte

Hello, I am having an SPI communication issue between an STM32H743BIT (SPI master) and a TI ADS7066IRTER ADC using SPI Mode 0 (CPOL=0, CPHA=0). I write a configuration register and immediately read it back, but the read value does not match what was written. The logic analyzer shows correct MOSI data, but MISO often returns 0xFF or 0x80, and the SPI decoder reports “Settings mismatch”. The write/read sequence is: SPI_ADS7066_writeSingleRegister(hADS7066, GENERAL_CFG_ADDRESS, OPMODE_CFG_CLK_DIV_6); if (SPI_ADS7066_readSingleRegister(hADS7066, GENERAL_CFG_ADDRESS) != OPMODE_CFG_CLK_DIV_6){Throw(EMBL_ERROR);} Write and read functions used: void SPI_ADS7066_writeSingleRegister(HANDLER hADS7066, uint8_t address, uint8_t data){PSPI_ADS7066DESC pADS7066Desc = (PSPI_ADS7066DESC)hADS7066;uint8_t dataTx[4] = {0};uint8_t numberOfBytes = SPI_CRC_ENABLED(pADS7066Desc) ? 4 : 3;EMBL_RETCODES ret; dataTx[0] = OPCODE_WREG;dataTx[1] = address;dataTx[2] = data;if (SPI_CRC_ENABLED(pADS7066Desc))dataTx[3]

Hi everyone,I’m experiencing a new issue with STM32CubeProgrammer and I’m wondering if anyone else has run into the same problem.Starting today, every time I try to select a file (for example, when choosing a .bin or .hex to flash), the program freezes as soon as the Windows File Explorer window opens. After a few seconds, the whole application closes without any error message.This has never happened before — the tool was working perfectly yesterday. The only thing that changed is that Windows installed an update overnight. Since then, STM32CubeProgrammer consistently crashes whenever it tries to open the file picker dialog.Has anyone seen this behavior after a recent Windows update?Any ideas on how to fix or work around it?Thanks in advance!

Hi,Comparison of STEVAL-ST25R3916B UM3033 [pg 22] & ST25R Antenna Matching Tool...Specifically the matching networks show a difference in location of parallel tuning capacitor relative to antenna connection. UM3033 antenna matching + filter [above].  Notice the location of the parallel tuning cap [C308] in relation to antenna connection ANT300.  The ST25R matching tool [above] shows antenna matching + filter.  Notice the parallel tuning cap is in spot closer to antenna connection than the UM3033 schematic. The physical STEVAL D25R16BA board shows the tunable cap next to the antenna [see red box below].  Silkscreen confirms this also.  Based on the above it seems that the STEVAL-ST25R3916B antenna matching schematic in UM3033 DOES NOT match the physical board. My question: Should tunable capacitor be placed as shown in the ST25R matching tool or should it be placed as shown in STEVAL-ST25R3916B UM3033?I've created a custom PCB f

Hello people. In 2020, our company made a PCB prototype (designed by me) which included a chip " ST25R95-VMD5T ". Our results were not good, but maybe this was due to a poor filter circuit and due to a poor matching circuit. The tag reading distance was very small, and the prototypes were not fixed (filter and matching), and we abandoned the project.  So in the same year of 2020, we were planning to make another PCB prototype, but then using the chip " ST25R3911B-AQFT ", with the intention that the reading of tags could reach a bigger distance, but we ended up not doing this prototype in 2020. Now, it's 2026, and we plan to make a PCB prototype, very simple. And our initial choice was the " ST25R3911B-AQFT ". I would like to ask if there are more recent chips than this, possibly one chip that can reach a bigger reading distance than this " ST25R3911B-AQFT ", or that reaches the same distance reading, but that has more recent technology. Remembering that this ti

In the version of cube mx 6.4.0 you can set parameters and advanced parameters, but in the version of cube mx 6.16.1 you can only select the chip in the platform setting in the LWIP in middleware. I configured the firmware by installing the KSZ8863RLLI LAN driver in the STM32F407VET6 MCU. Cube IDE used version 1.18.1. Ping test went well in the version of cube mx 6.4.0 and it doesn't work in the version of cube mx 6.16.1. Is there a way to do it in the version of cube mx 6.16.1? What are the problems?The 00.ETH file is the firmware created in the version of cube mx 6.4.0 and the 02.ETH_16.1 file is the firmware created in the version of cube mx 6.16.1

Hello, I am planning to use the STM32G474RET6 and would like to confirm whether I can use the internal VREFBUF. This product's package is LQFP-64 and while reading the datasheet I noticed the note : ''The VREF+ pin is double-bonded with VDDA on some packages''. Could you verify whether the internal reference voltage can be used with this package?   Thanks.

hi community  i am using  "AEK-AUD-C1D9031"  board. in this board i had flashed  .WAV files and i had played. the wave files are played using an example code given in the autodevkit. i used an API playsound() this one will give good sound when i had used playsoundwithgain() -> the gain with range (15,17) the sound quality was good with decent amount of volume. but hear i want to control the volume  (0db - 75db),but by using playsound() and playsoundwithgain() i am unable to control the volume( the sound will be very noise when i had used gain in range of ( (0-14) and (17- so...on) ). so is there any alternatives to control the volume of the sound.   hear is the pic of the function which i had used.
