Hi all! I'm trying to implement a wear leveling in user memory accessed from I2C for a counter on bit level. My question is: Are ST25DV eeprom byte cells similar to classic ones where each write cycle starts with a clear (which sets the byte to 0xFF) and after it writes 0 bits where needed? Or is there somewhere an inversion taking place? Could someone help me, by pointing out some directions in datasheets for me in this matter? I found another post where memory default state is quoted from the datasheet which specifies that factory default is 0x00, but this doesn't imply that it's default state isn't 0xFF. Thanks in advance, notram

I have been using RFAL succesfully with STM32L4. For a more price sensitive project I need to port the code to STMG070 and I cannot get RFID readings to work. Measuring ampltiude gives same result on both codes:st25r3911MeasureAmplitude(&c); printf("Amplitude %d\n\r", c); The following have been verified:* Same RFID PCB is used for both processors (RFID PCB and processor PCB are connected by pin connector)* Same RFID card is used* Init of RFAL gives ID 13 on both codes* GPIO interrups are generated* Same LDO on both PCB* Voltage to ST25R3911B is stable* Both processors runs at same frequency 16 MHz On STM32L4 the state change (during a succesful RFID read) of rfalNfcWorker goes like:RFAL_NFC_STATE_IDLERFAL_NFC_STATE_POLL_TECHDETECT x 19RFAL_NFC_STATE_POLL_COLAVOIDANCE x 29RFAL_NFC_STATE_POLL_ACTIVATION x 2But when running on STM32G070 RFAL_NFC_STATE_IDLERFAL_NFC_STATE_POLL_TECHDETECTRFAL_NFC_STATE_LISTEN_TECHDETECT until timeout  Anyone have

The STM32L476 does not have an nBOOT0 option bit in its option bytes. Is there a way to boot from the main flash memory without using the BOOT0 pin?

I'm developing using the STM32WBA65I-DK1. I'd like to know how to implement interrupt handling for button presses. It appears that stm32wba65i_discovery.h does not contain any APIs related to button presses (which is perhaps to be expected since the DK does not have push buttons). The sample code I'm using is BLE_HeartRate_Thread. If you have any source code that might be helpful, please let me know.

Hi everyone,I'm facing a really frustrating issue where my STM32CubeIDE can no longer detect my ST-LINK, and I've narrowed the problem down specifically to stlinkserver.exe failing to launch. This problem appeared completely randomly on my PC.Here are the symptoms and what I have already ruled out:The Problem: When I try to manually execute stlinkserver.exe via PowerShell to see what's wrong, it exits instantly without printing any output, errors, or logs. Even forcing the help menu or debug mode does absolutely nothing:PowerShell PS C:\Program Files (x86)\STMicroelectronics\stlink_server> .\stlinkserver.exe PS C:\Program Files (x86)\STMicroelectronics\stlink_server> .\stlinkserver.exe -d 5 PS C:\Program Files (x86)\STMicroelectronics\stlink_server> .\stlinkserver.exe -h Running Get-Process stlinkserver confirms the process is not running in the background at all. It just dies immediately upon execution.What DOES work (Hardware & Drivers are fine):STM32CubeProgrammer

Hello everyone   i am currently working on a project with a NUCLEO-C092RC Board. With this Board i want to send OBD-II Frames to my car and receive reponses with data. I also use a LCD Display via SPI. But now i have a problem. i connected CANH/L with the Board. I also connected 12V and GND from the OBD-II-Port to a buck converter, which steps the voltage down to 7 V for VIN on the Board, which should be within spec. Then i tried to send a frame, but i did not get a response, when the Board was only powered by 12V via buck converter. After that i think i broke my MCU, because then i connected my PC with the Board and switched the power source back from VIN to ST-Link with a jumper. I was able to debug my programm. but when i also disconnected CANL and CANH from the Board or switching the jumper from VIN to ST-Link (i am nor sure anymore), the red LED from STMPS2141STR came on. It only turns off, if i disconnect VDD from 3V3 Volt with pulling JP5. I also measured from what i think

Hello,   I would like to learn if there is an easy way in STM32CubeMX2 to start a new project with an existing ioc2 file. It seems that the only way I can do this is make a copy of the ioc2 file, do a text find and replace for the name of the project and reopen the project in MX2. In essence, I like to start a project from a working ioc2 configuration and modify it to work on a fork of the project. I don't want to recreate a complex configuration from scratch because I found the hard way that it is easy to make mistakes or to omit something.   Thank you, -Gil   Please check the follow-up discussion here: Issue with Save As feature in STM32CubeMX2

I'm designing a USB-C charging circuit for a battery-powered device using the STUSB4531 for PD negotiation alongside a BQ25792 buck-boost battery charger. The BQ25792 handles the full VBUS power path internally (inrush limiting, reverse current protection, OVP, and dead battery support), so I'm trying to understand whether the external P-FET that STUSB4531 normally drives is still required. Specifically: 1. Can the GATE pin be left NC or tied off without affecting CC detection and PD negotiation? Or does the IC require a valid FET load on GATE to operate correctly?2. If the GATE pin must drive something, would it be acceptable to connect GATE to the BQ25792's CE (charge enable) pin instead of a FET gate — effectively using it as a charger enable signal rather than a loadswitch?3. Dead battery / no battery scenario: I need the system to power up from VBUS even when the battery is absent or fully depleted. The BQ25792 already supports dead battery mode on its own. If the external FE

Hello, I want to use an I2C port of a STM32F411 MCU (MCU_A) in target mode to receive data from another MCU (MCU_B), MCU_B code already existing and verified with other receivers.I configured the project with STM32CubeMX, with interrupts enabled to handle communication in interrupt mode.I used MX standard settings to generate CubeIDE project with HAL code.With some effort for setting up the initialization and other code for MCU_A in CubeIDE, communication looks ok from sending MCU_B perspective.Additional check of SDA and SCL signals with DSO looks ok to. But the problem was: No data was transfered to the receive data buffer in MCU_A. After several hours of debugging, I found a suspicious code section in the HAL code (stm32f4xx_hal_i2c.c).In the HAL function     static void I2C_Slave_ADDR(I2C_HandleTypeDef *hi2c, uint32_t IT2Flags)which is called in     HAL_I2C_EV_IRQHandler ()when adress matches, the direction flag received from MCU_B

I am trying to troubleshoot and reverse engineer a project no longer in production and for which the developer is no longer reachable.  The project is based on the ST MB997C and uses an attached daughter board that serves as an R232 communications interface to external I/O (whatever other functions it may perform are unclear).  Are there PCB suppliers that manufacture MB997C compatible PCBs to provided specifications?  The subject PCB in this project is silkscreened with the project name "ProBox V1R1", so it is not a generic OTS part.  Also, are there resources out there that can reverse engineer the functions of this PCB?  Any guidance would be greatly appreciated. 

Hi,I've P-NUCLEO-6283A1 and downloaded the graphical user interface STSW-IMG301. The quick start guide does not seem to be up to date as I did not find "VD6283_setup.exe" I was supposed to install, just a plain exe in the zip.At the first try GUI complained that it cannot communicate with the board. Next I updated the firmware with the GUI. Now when trying to start I get error complaining about invalid product version. What is going on here? Does the GUI ship with incorrect firmware binary?My board 

I'm running into an issue where my STM32G4 gets stuck in an infinite while loop inside R3_2_SwitchOffPWM() during the motor control initialisation sequence, and I wanted to share it here in case others have encountered the same thing.---Hardware & Software- Board: EVSPIN32G4- Code generation tool: ST Motor Control Workbench v6.4.2- No manual edits made to any generated files---What happensDuring startup, MX_MotorControl_Init() is called from main(), which triggers MCboot() → FOC_Clear() → PWMC_SwitchOffPWM() → R3_2_SwitchOffPWM().

Hi, I made a custom board and made a design in touchgfx. But my screen keeps being black.I want to confirm something because I think I made a mistake in my design. I selected the following display:MDT0130CIS-MULTI:https://www.farnell.com/datasheets/4321575.pdf?_gl=1*vshmrc*_gcl_aw*R0NMLjE3NzUxMjEwOTIuRUFJYUlRb2JDaE1JM1BxQnEtbk9rd01WdHprR0FCMXQ5Z2k1RUFRWUFTQUJFZ0xmZVBEX0J3RQ..*_gcl_au*MTM4MTIxMjM2Mi4xNzc2NDEzMzk5 Now in the datasheet from the ST7789V driver which is on board of the MDT0130CIS-MULTI display it says the following.Can I conclude from this that I cant drive this display with LTDC and Touch GFX?Kind regards, WilliamP.S.I included my .ioc file and main.c file if that could help. 

    Dear Team, We are planning to design a custom board based on STM32H745IIT6.We would like to request whether STMicroelectronics can provide any official reference design (schematic, PCB files, or recommended evaluation board) specifically for STM32H745IIT6. If there is no dedicated reference design for this exact part, please let us know: Which existing STM32H745/H747 Discovery or Evaluation board can be safely used as the hardware reference for STM32H745IIT6 Any recommended documents or design guidelines to follow for production hardware Kindly share the relevant links or document references. Thank you for your support. Regards,Sathiya

Just a heads-up, this post was written by AI. I used it to document a process of debugging this board, and create a summary for a forum post.Platform: ST25R3911B, RFAL library, ISO 14443AConfig: Single-ended mode, 0.3m 50Ω coaxial cable, remote antenna PCBSupply: 5V on VDD and VIORead range: ~10mm (expected 40-80mm for antenna size)Setup OverviewI'm using an ST25R3911B driving a remote PCB antenna via a 0.3m 50Ω coaxial cable in single-ended mode (RFO1). The antenna is a 2-turn square loop, 70×70mm outer dimension, 1.4mm trace width, 0.7mm spacing, calculated inductance ~735nH.The chip drives two antennas switched alternately — RFO1 to the remote antenna via coax, RFO2 to a local antenna. Both antennas show identical poor range (~10mm), so the problem is not specific to the coax path.Hardware — Reader PCB Matching NetworkDesigned using the ST25R Antenna Matching Tool V3.6.2 with these parameters:Target: ST25R3911BConfig: single-ended-cableAntenna inductance: 701 nHTarget matching Z: 8

Hello everyone,I am currently trying to create a CMake based C-project for the ST Evaluation board STM32H757I-EVAL, that allows me to render a UI on the MIPI DSI connected display, that comes with it.Due to other work related requirements, I don't want to use TouchGFX, but will later try to add the LVGL framework to create our UI.However, at time of writing I have been unable to configure my project in such a way, that I can manually fill a Framebuffer and have that have any effect on the display. I have created a github repo with a "minimal" example of the configuration efforts so far.A "short" overview:I tried to create said CMake project through the STM32CubeMX code generator, and after a lot of trial, error and misunderstanding what is and isn't generated, I added the ST libraries for the external SDRAM "IS42S32800J" as well as the display driver IC "OTM8009A" and tried to configure the clocks and configurations of the following components:GPIO of the attached display pinsFMC to en

Hello everyone, I have a NUCLEO-H755ZIQ board and I am trying to use the HRTIM to output a 50Hz pwm signal. I hook the output to an oscilloscope and I see that the pulse has a period of 19.2ms instead of 20ms, meaning that while I have configured the clock for the HRTIM to run at 2MHz (meaning that it needs 40000 ticks to complete a period) it runs at 2.6MHz. Can anyone help me understand what am I doing wrong? I have attached the .ioc file. Thanks in advance!

Hi all,I designed a custom STM32 board that powers up, but the firmware starts only after I manually press the reset button. Once reset is pressed, everything works normally. The clock source is an external crystal, and BOOT pins are configured with resistors. Questions: Should I suspect reset timing, clock startup, or BOOT pin state first? Would increasing reset delay with an RC network help? On the PCB, how close should crystal traces and load capacitors be placed to the MCU pins?

Hello ST Community,I’m working with the STM32 Nucleo-N657 board and need a way to execute my application after flashing to external memory without manually toggling the BOOT1 jumper on the board.What I’m Doing Now:BOOT1 jumper is set to HIGH for development (DEV boot mode)I have a simple LED blink application built with GPIO configured in the FSBL context The code runs as expected in DEV mode (debug mode of STM32CubeIDE)I then flashed the signed binary in external memory using STM32CubeProgrammer and External Memory loader for Nucleo-N6 board at address 0x70000000. Then, I switched BOOT-1 jumper to LOW and reset the board. The code runs as expected from external memory.Problem:I have N6 board connected to a remote PC and won’t always have physical access to toggle the BOOT1 jumper and press reset.I would like to know:Is there a programmatic or configuration-based way to run the program automatically after flashing, without needing to change the BOOT1 jumper man
