Hello,I am working with STM32 TouchGFX on a Riverdi board. I would like to use the board-specific settings in offline mode. Are there any files available for specific boards? If so, is it possible to transfer those files via a flash drive and use TouchGFX with the specific board on a computer without internet access, by placing them in the appropriate directory?

Hello,Murata has announced that the variable capacitors LXRW0YV201-059 will become obsolete in 2026.https://www.mouser.com/PCN/Murata_PCN_for_Mouser_(LXRW)_Mar._6_2025.pdfThese components are part of the antenna matching/EMI filter circuit in the STEVAL-ST25R3916B schematics.Do you have any recommendation for an alternative reference to replace these capacitors once they become obsolete ?Thanks in advance,Best regards

Can you please let me know will there be any concern in using these memories or anything i need to take care in design

Hi,I'm using an ST25DV64KC tag to communicate with an Android app using the st25 sdk and the Mailbox. The problem arises when the app reads a message of the maximum mailbox capacity. In that case, an 0xE4 character appears as the last character but I'm pretty sure the firmware didn't put it. Here is an example of an interaction2025-05-12 08:32:09.466 12263-19515 Iso15693CustomCommand   com.wavecontrol.mtiotmobileapp       D  ==> Send readMsgLength command: 22 ab 02 7f 46 b6 7c 67 51 02 e02025-05-12 08:32:09.480 12263-19515 Iso15693CustomCommand   com.wavecontrol.mtiotmobileapp       D  Response: 00 ff2025-05-12 08:32:09.483 12263-19515 Iso15693CustomCommand   com.wavecontrol.mtiotmobileapp       D  ==> Send readMsg command: 22 ac 02 7f 46 b6 7c 67 51 02 e0 00 ff2025-05-12 08:32:09.588 12263-19515 Iso15693CustomCommand   com.wavecontrol.mtiotmobileapp       D  Response: 00 02 7b 22

Hi ST community,I'm using the STM32F303ZE in a design and need to ensure that the clocks for various peripherals stay within acceptable tolerances (in ppm or %) — especially across the full temperature range (–40°C to +105°C). I plan to use an external HSE crystal oscillator, and I’m trying to validate whether my chosen crystal (in terms of stability and accuracy) will meet the needs of the following peripherals.Could you please help clarify the maximum allowable clock frequency drift for each of these peripherals:USART (1–5)What is the maximum clock drift (in % or ppm) tolerated between the transmitter and receiver over temperature?How do oversampling modes (8x or 16x) and word length (M bits) affect this tolerance?USB FSI understand it requires 48 MHz ±0.25%. Is this tolerance strictly enforced by the USB hardware?SPI (1–3)For slave mode, is there a specified maximum allowable clock skew or drift from the external SPI master?Are there any special considerations when using HSE as the

Hi everyone,I'm working with an STM32 microcontroller and the LoRaWAN stack provided by ST. My goal is to initialize LoRaWAN only when a button connected to pin PA0 is pressed.I verified with a multimeter that PA0 is at 0V when idle and goes to 3.3V when the button is pressed, so the hardware seems fine.In the code, I'm calling MX_LoRaWAN_Init() only if I detect PA0 is HIGH and a debounce time has passed. However, LoRaWAN never starts, even if I hold the button for several seconds.Below is the full main.c file, including the logic for PA0 detection and conditional LoRaWAN startup: /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2025 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LIC

I have NUCLEO-F756ZG board with STM32F765ZG and I have hooked up ICS43434 mic into I2S1 bus. Now I have been scratching my head for a day to figure out how to get data out from that puppy. Or actually getting data out is simple, but to make it sane is not. I have configured I2S and DMA like belowThen I allocate some buffers and write DMA callbacks and send the data to freeRTOS task for processing. Now if I play 1kHz sound and dump the raw data from DMA buffers I get something like this113,58880,0,0,116,43008,0,0,123,4608,0,0,134,42496,0,0If I draw the 113, 166 so every 4th sample to graph it is the sine wave what I am playing. My friend the AI said that the data format is left_high, left_low, right_high, righ_low. That might very well be, but I don't want that. If the mic sends 24 bit of data in 32 bit frames it feels insane that I have to spend 2*32bits of memory for it.I just can't figure out what am I missing. It does not help HAL_I2S_Receive_DMA is one big red herring, but I b

I am using the startup file in Keil. However, when I run the simulation in the debugger, my system clock (SYSCLK) is not 72 MHz, even though I have confirmed that HSE_VALUE is set to 8 MHz.Can someone help me figure out why the SYSCLK is incorrect during simulation? I am using stm32f103c8t6 bluepill

 Does the STM32U5G9ZJT6Q SoC not support SDMMC2?

I want to set up 100MHz for SDRAM.STM32CubeIDE version 1.18.1 has the following options for SDRAM clock:The selected board is the STM32H743IITx. RM0433 Rev 8 states that:I'm not sure HCLK and fmc_ker_ck are the same thing.If I have my FMC clock set up as:And select HCLK/2, I'll have 100MHz for the SDRAM? Or is HCKL system clock?

Hello,I have the very excellent book "STM32 Arm Programming for Embedded Systems" by Mazidi, Chen, Ghaemi.  It is from 2017.  The book uses Keil, which I am very happy to use, and it has very nicely written code which I fully understand (so nicely written!).I am having trouble getting a project going in Keil because in the book when you make selections in 'Manage Run-Time Environment' during the project set up is says to tick 'System Startup for STMicroelectronics STM32F4 Series', but in my version of Kiel, it says something like 'use Cube IDE/MX' and no option to use 'System Startup for STMicroelectronics STM32F4 Series'.Could someone help with this? I do NOT want to use Cube IDE etc. all that software its horrible.Thank you in advance!

I am using the following setup:- STMCubeIDE1.6.1 on Windows 11I see the following behavior- Opening the IDE with the default Toolchain and my Project for 1.6.1 works fine and build. However, I need to use the GNU Tools for STM32 (7-2018-q2-update)- I install it with the Toolchain manager which works. Then I have to restart the IDE for the Toolchain to become active.- After the restart the IDE is missing the usual C Project settings like Build C/C++ and the Toolchain manager. (see Image). Furthermore I get the 'Missing builder indication under the 'Builder' settting.- Strange enough using this Toolchain works with newer IDE versions like v1.10.1 for other projects but I need to use v1.6.0 or v.1.6.1- Only reinstalling the IDE can fix the issue.    

I followed the GPDMA tutorial here:https://www.youtube.com/watch?v=jKOhRfb3gvkand configured everything as shown.  The workshop was on a U575 but I would assume it's the same configuration for the U5A5?  I'm using the Nucleo-U5A5ZJ-Q.  I'm unable to get data passed via DMA into my data array.  I can see the ADC1->DR register getting continuously updated, but my data array remains zero length.I've attached a zipped project.Any help would be appreciated.

Hi all,I need to integrate the driver for the iis2mdc magnetometer (Github: https://github.com/STMicroelectronics/stm32-iis2mdc/tree/main) into my own project for a custom board (with STM32H7A3 and i2c3).  The code from the driver requires an additional hardware driver so that the magnetometer can be read/written to. However this interface functions are not included in the driver on Github. int32_t __weak iis2mdc_read_reg( ...) and int32_t __weak iis2mdc_write_reg(stmdev_ctx_t *ctx, uint8_t reg,uint8_t *data,uint16_t len){int32_t ret;ret = ctx->write_reg(ctx->handle, reg, data, len);return ret;} Is there any sample code available, which can be simply adjusted for the specific i2c interface? or do I simply have to replace the call:ret = ctx->write_reg(ctx->handle, reg, data, len);    by  the corresponding    HAL_i2c... calls? Many thanks for any hints.BR GS    

Hello!When I build my project, I get these errors.

For this project I used a TDA7265 in beige configuration directly following the circuit diagram from the datasheet. In testing, no sound is coming from the speaker, only a hum. I’m using a 12V 1 A dual rail supply with an 8 ohms speaker. I have demonstration for this project on Thursday. I’m not sure if it’s stuck in standby mode/mute mode so I’m seeking some clarity on this whole thing. I have picture of the circuit I used for my PCB however there’s a mistake that I caught in testing regarding the output. I fixed that but I can’t see why the speaker doesn’t automatically sound. 

STM32CLT has written an environment variable %STM32CLT_PATH% when it was installed, and the "armToolchainPath" is specified also in launch.json. Why not use it when creating a project, and try to search for the tool chain in PATH? Instead, you people write the entire toolchain into system-wide PATH, that will stop other MCU's toolchain from working!  To Fix: change cmake/gcc-arm-none-eabi.cmake:11 and following to: cmake_path(SET TOOCHAIN_PATH $ENV{STM32CLT_PATH} ) set(TOOLCHAIN_PREFIX ${TOOCHAIN_PATH}/GNU-tools-for-STM32/bin/arm-none-eabi-) set(CMAKE_C_COMPILER ${TOOLCHAIN_PREFIX}gcc${CMAKE_HOST_EXECUTABLE_SUFFIX}) set(CMAKE_ASM_COMPILER ${CMAKE_C_COMPILER}) set(CMAKE_CXX_COMPILER ${TOOLCHAIN_PREFIX}g++${CMAKE_HOST_EXECUTABLE_SUFFIX}) set(CMAKE_LINKER ${TOOLCHAIN_PREFIX}g++${CMAKE_HOST_EXECUTABLE_SUFFIX}) set(CMAKE_OBJCOPY ${TOOLCHAIN_PREFIX}objcopy${CMAKE_HOST_EXECUTABLE_SUFFIX}) set(CMAKE_SIZE ${TOOLCHAIN_PREFIX}size${CMAKE_HOST_EXECUTABLE_SUFFIX})that's quite bit e

Hello! I'm working with FreeRTOS for the first time and am getting a HardFault during the call HAL_NVIC_EnableIRQ(TIM4_IRQn); call inside of HAL_InitTick(); from HAL_Init();I am currently testing with a Nucleo board with MCU STM32F401RET6U and have configured the project as such - the startup file is startup_stm32f401retx.s.I've tried both TIM4 and TIM5 for the Timebase Source and have had the same results. Nowhere else in the code is TIM4 used or initialized I'm confused why it is hanging on the HAL_NVIC_EnableIRQ call.Does anyone know what the issue could be or how I can further debug the issue? int main(void) { //Segger SystemView initialization //Enable the CYCCNT counter DWT_CTRL |= ( 1 << 0); SEGGER_SYSVIEW_Conf(); SEGGER_SYSVIEW_Start(); // Also tried above SEGGER Init and result hangs and disconnects instead of Hard Fault HAL_Init(); CppMain(); }  

 I want to use Macro "__LL_ADC_CALC_TEMPERATURE" to calculate the chip's temperature. But there is a difference here. As mentioned above, in datasheet, TS_CAL2 corresponds to 130 ℃.But in STM32Cube FW_G4 V1.6.1, file "stm32g4xx_ll_adc.h", line 386, TEMPSENSOR_CAL2_TEMP corresponds to 110 ℃. Which one is ture?

Hi @stm32 I have a STM32G070 chip connected to a NOR_FLASH MX25L6433F using Standard SPI. I created an External Loader for the setup, but unable to read/write using the stm32 programmer. The custom driver for the particular flash is proved to work with the same hardware setup, so i can confirm that the bridging between the working driver and the STM2Programmer is somewhat missing. I created an External loader from scratch following the STM32 MOOC course link (https://www.youtube.com/watch?v=xASKxhqphkk&list=PLnMKNibPkDnHIrq5BICcFhLsmJFI_ytvE&index=4) for QSPI.Steps I followed:1) Created a CubeMx project for stm32g070 with SPI enabled in my case.2) Manually copied the loader files from the link https://github.com/STMicroelectronics/stm32-external-loader/tree/contrib/Loader_Files and also integrated my custom driver for the particular NOR_FLASH. The driver is tested and verified separately,So it works.3) In the build configurations, pasted the command cmd
