Hello!I am working on a project using the STM32U375CGUx MCU, and I am trying to implement a Stereo Audio Acquisition system using two omnidirectional digital PDM MEMS microphones.Hardware Setup: Microphone L: L/R pin tied to GND (Rising Edge data output). Microphone R: L/R pin tied to VDD (Falling Edge data output). Both microphones share the same lines connected to the MCU: PB4 (ADF1_SDI0) for the clock and PB3 (ADF1_CCK0) for the data stream. The Issue:When configuring the peripheral through STM32CubeMX, I am unable to set up a true Stereo configuration. I can only make it work in Mono.Looking at the generated HAL initialization code, I am forced to choose either MDF_BITSTREAM0_FALLING or MDF_BITSTREAM0_RISING for the FilterBistream parameter. There is no option/macro to sample both edges (interleaved) simultaneously on the same filter instance:AdfHandle0.Instance = ADF1_Filter0;AdfHandle0.Init.CommonParam.ProcClockDivider = 6;AdfHandle0.Init.CommonParam.OutputClock.Activation =

Hello,I’m working with custom board STM32F767BITX, trying to interface Standalone USB Host MSC, with no Free RTOS.Tried different reference, below is one reference which I followed  As soon as connected USB, it shows connected but after that it loop between this two calls alternatively, USBH_LL_PortDisabled() and USBH_LL_PortEnabled() which disconnect USB and connect again and continue to do that.So I dont understand the root cause of this, what trigger this to behave like this?Please guide me to fix this issue. void SystemClock_Config(void){ RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Configure the main internal regulator output voltage */ __HAL_RCC_PWR_CLK_ENABLE(); __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE3); /** Initializes the RCC Oscillators according to the specified parameters * in the RCC_OscInitTypeDef structure. */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_HSE; RCC

Hello, I'm using an STM32U5G7VJTx MCU with a 480x320 display, connected to the FMC in 16-bit mode, and everything works fine using the GPU2D. I'm not using an existing GUI framework.The pixel format used by the display is RGB565 (16bpp), so for gradients, I want to use dithering to soften the banding. I found this definition in the 'nema_graphics.h' file:#define NEMA_DITHER 0x80U /**< Nema Dithering */However, it seems undocumented. How do I make use of it?Kind regerds, Jack.

I am using an STM32F401RET with the Simulink STM32 support package.My problem is that I am measuring a pure sine wave from a voltage sensor. I verified the sensor output using an oscilloscope, and the waveform is clean. However, the ADC readings on the STM32 show a very low-quality signal that appears as a stepped waveform rather than a smooth sine wave.I have already tried increasing the sampling rate, running the ADC at its maximum clock speed, and using a timer as an external trigger source for the ADC, but none of these solutions improved the result.I would appreciate any suggestions on what could be causing this issue. 

Hi,I have a problem with my custom container. I made a custom keyboard container in my project (4.26.1 compile is ok). I would like use this in another project.I exported this container which works.In the another project i import the widget, but compiler get unexpected error.What is the problem with widget?Thank you!These are the designer logs:2026-06-19 09:15:01,186 [1] ERROR TouchGFXDesigner.App: Object reference not set to an instance of an object.System.NullReferenceException: Object reference not set to an instance of an object.   at TouchGFXDomainModel.LoadSave.Serial.ToSerial.Convert(TriggerCustom t)   at TouchGFXDomainModel.LoadSave.Serial.ToSerial.Convert(Interaction i)   at System.Linq.Enumerable.IListSelectIterator`2.ToList()   at TouchGFXDomainModel.LoadSave.Serial.ToSerial.Convert(CustomContainerDefinition c)   at System.Linq.Enumerable.IListSelectIterator`2.ToList()   at TouchGFXDomainModel.LoadSave.Serial.ToSerial.Convert(Application a)   at TouchGFXDomainModel.LoadSave.

Are there plans to update CubeMX to support MacOS 27 and later? I have just installed 6.17.0 under MacOS 26 and I get a warning to say the installer will not work with later versions:This is because support for the Intel translation layer will be removed (M series Macs are now into their 5th year).Note the CubeMX app itself does not get this - just the installer.

Hello.I have a project created earlier in CubeIDE 1.9.x, which I imported into the new CubeIDE 2.1.1. However, due to some issues with the project/code, I want to revert to the basics and create a fresh new project.There are some issues:In CubeMX 6.17.0, when configuring GPIO pins, nothing appears in the GPIO window:Additionally, there are problems with ICACHE:I cannot generate code without warnings.These problems occur when creating the project.Closing the IOC file and CubeMX, then reopening the IOC file a second time, resolves the issue. I can live with this workaround, but I’m reporting it.The second problem is in CubeIDE: when importing a project, the “C/C++ Index” tab is missing:Also some tabs missing in Properties:What I’m doing wrong?I followed the instructions exactly as in the video from this topic: PS. Sorry, there are mistake in title: CubeMX 6.17.0, not 1.67.0.

Hi team,i’m using a SensorTile.Box Pro and want to increase the Bluetooth RF power of the STM32WB07KC (BlueNRG-LP) with an external Power Amplifier and external Antenna. So, i appreciate to be able to modify the code of this chip, BlueNRG-LP, not the one of the STM32U585.Can ST provide the source project corresponding to:FP-SNS-STBOX1/Utilities/DTM_BlueNRG-LP/SensorTile.Box_PRO_R20_DTM_SPI.binThe image reports:DTM 1.2.0DTM Variant 0x02 (SPI)BLE Stack 3.1.1Build 49063The firmware has been successfully dumped and compared against the distributed binary, confirming that the running image matches the official ST binary.I would like to: Understand how aci_hal_set_tx_power_level() is handled in this firmware and whether RF output power is intentionally limited on STEVAL-MKBOXPRO. Determine whether TX_SEQUENCE / RX_SEQUENCE GPIO alternate functions can be enabled in this project. Drive an external 2.4 GHz PA/LNA front-end (e.g. SKY66118-11) using a dedicated TX control signal.

Hello,I am trying to obtain the old STM32CubeExpansion_LRWAN_V2.0.0 package (I-CUBE-LRWAN v2.0.0), but I can only find the current versions on the ST website.I specifically need version 2.0.0 for compatibility with an existing project based on the original LoRaWAN stack provided by ST.I have already checked:The current I-CUBE-LRWAN page on st.com STM32Cube repositories and mirrors on GitHub Archived documentation and release notesUnfortunately, I have not been able to locate the original archive (STM32CubeExpansion_LRWAN_V2.0.0.zip).Does anyone know:Where this version can still be downloaded? Whether ST keeps an archive of legacy expansion packages? If there is an official replacement package fully compatible with v2.0.0?Any help or archived download link would be greatly appreciated.Thank you.

Hi all, we have developed a video capture application and are field-testing this right now. In order to optimize perceptual quality, we are tuning the quality parameters to find a good trade-off.I saw in the h263encapi.h some features mentioned that are interesting to our application but could not find out if the VENC hardware actually supports it, likeRegion of interest cyclic intra refresh  Video stabilization (although I fear that memory bandwidth is a limit here)I have read the Hantro Software Integration Guide in the github repository but that does not go into detail on what is available on the STM32N6.It seems that there has been an earlier discussion in this topic mentioning an Internal ticket number: 209269Could we have a feature map on what the IP block actually supports and the related software documentation?Thanks a lot Simon

Good morning everyone,I need to drive an external pump using DAC out pheriperal.I am working with an STM32H562ZI microcontroller and have followed the guide available at the following link: Getting started with DACBelow is my current configuration:/** * @brief DAC1 Initialization Function * @param None * @retval None */static void MX_DAC1_Init(void){ /* USER CODE BEGIN DAC1_Init 0 */ /* USER CODE END DAC1_Init 0 */ DAC_ChannelConfTypeDef sConfig = {0}; /* USER CODE BEGIN DAC1_Init 1 */ /* USER CODE END DAC1_Init 1 */ /** DAC Initialization */ hdac1.Instance = DAC1; if (HAL_DAC_Init(&hdac1) != HAL_OK) { Error_Handler(); } /** DAC channel OUT1 config */ sConfig.DAC_HighFrequency = DAC_HIGH_FREQUENCY_INTERFACE_MODE_ABOVE_80MHZ; sConfig.DAC_DMADoubleDataMode = DISABLE; sConfig.DAC_SignedFormat = DISABLE; sConfig.DAC_SampleAndHold = DAC_SAMPLEANDHOLD_DISABLE; sConfig.DAC_Trigger = DAC_TRIGGER_NONE; sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE; sConfig.DA

So, I was showing some friends in England how to use the Sensor TileBox Pro to measure a building, using the modified CLI_EXAMPLE program.  So starting analysis, the X axis now representing gravity vector in the table, I knew I had the box sitting on its side in a slot in the column, so if I am looking at the box, I was wondering what axis system matched the box and the unit.  Your data sheet showsThe whit dot is importantI think the white dot is in the bottom right hand corner, is the white dot on the board an indicator so X is parallel to the short axis of the box laying down, the Y axis is parallel to the long axis lying down and the Z axis is vertical.   Please confirm, as I have no desire to take the box apart.   

 Hello ST Community,I am working on a custom STM32-based board and would like to know whether STM32CubeMX provides any official feature to add our own custom board to the Board Selector, similar to ST Discovery, Nucleo, or Evaluation boards.My requirement is that when creating a new project, I should be able to select my custom board and automatically load the default settings such as MCU, pin configuration, clock settings, peripherals, and middleware from a predefined .ioc file.Is this feature officially supported by STM32CubeMX, or is the recommended method to manually create and reuse a base .ioc file for each custom board?Thank you. Vijaya

Hi,We are currently evaluating the possibility of booting an STM32N655X0-based custom board from an SD card and would appreciate some guidance before committing to this design.Current Setup MCU: STM32N655X0 Custom hardware Currently, the FSBL is downloaded directly into RAM during development. The FSBL then loads the application from external flash. We would like to migrate to SD card boot. Understanding from UM3234While reviewing UM3234 - How to Proceed with Boot ROM on STM32N6 MCUs, I found the following description (page 15):In data transfer mode, the Boot ROM searches for two FSBL images. It first looks for a GPT header at LBA1. If GPT is present, the Boot ROM uses the GPT table to locate the FSBL images. If GPT is not found, it falls back to the default locations: FSBL1: LBA 128 FSBL2: LBA 640 Our goal is to use a single SD card for both: Storing the FSBL used by Boot ROM Storing application data using FileX What We TriedOption 1: GPT PartitioningWe partitioned the SD

I need to create, read and modify files using filex. Such files have names that uses cyrillic characters set (they must be codified using unicode 16 bit). It is possible to manage such files? Thanks

Hello folks,I am investigating the Video Encoder on the STM32N6 and have been working through the reference project (VENC_SDCard_ThreadX).The user manual (RM0486) is very vague on detailing the Video Encoder, and lists over 100 pages of registers which appear to be referencing other Software Registers (VENC_SWREGx):There are approximately 500 of registers like these, and it doesn't really say much. Looking through the `asicRegisterDesc[]` structure in the Middleware has been useful to try and see what the registers are used for, but still is nowhere near the amount of detail that is needed.Any further info would be greatly appreciated.Kindest regards, 

I have used the HAL_Delay function as below, the micro is stm32g474ret6.while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ HAL_GPIO_WritePin(LED2_GPIO_Port, LED2_Pin, SET); HAL_GPIO_WritePin(Buzzer_GPIO_Port, Buzzer_Pin, RESET); HAL_Delay(1000); HAL_GPIO_WritePin(LED2_GPIO_Port, LED2_Pin, RESET); } /* USER CODE END 3 */}The problem is the code always struck in the HAL_Delay function  with uwTick always returning 0. The systick interrupt handler is not called. Another observation if i enable the timer1 interrupt (i assume enable any interrupt) the code is reset. I generated the PWM using timer1 without interrupts. What is the problem when i enable interrupts how do i check it? Is it something to do with the Interrupt vector table.

i am using a 256K flash version of the STM32G0B1RE. part of the code is to use page 127 for various settings. when the device first starts up i set these settings at address 0x0308F800 this works perfectly. when i update a settings i erase page 127 then write the new settings. For some reason i cannot erase page 127, i am using single BANK mode, i think. when i pause to examine registers and memory i cannot see all the bits in the FLASH register. Suspect there is an issue with the svd file.i have used this technique successfully on other CPU versions so i am confident the basic code works. i think i am missing something around the 1 bank or 2 bank settings for this processor.any help appreciated. Mark

Hi, For a reason that I cannot explain, the STM32U575ZI (on the nucleo board) is sending a CAN bus message with infinite repeats and 100% bus utilisation, but I have repeated transmission turned off (DAR bit set to 1) and I have confirmed this using the debugger. It continues to send this message at full rate even if I pause the device in the debugger. My code is configured to send a packet with a changing ID from 0 to 4, but the repeated message always has the same ID (0x1, the first message that was queued), indicating that the message is stuck in the TX FIFO. FDCAN_TXBRP is always 0x1. Interrupts for the FDCAN peripheral are not enabled.   I have the following code as my main loop: if (HAL_FDCAN_Start(&hfdcan1) != HAL_OK) { Error_Handler(); } FDCAN_TxHeaderTypeDef header; header.Identifier = 0; while (1) { const uint8_t tx_data[] = {0x01, 0x23, 0x45}; while (HAL_FDCAN_GetTxFifoFreeLevel(&hfdcan1) != 3) { HAL_Delay(1); } header.Identifier = (header.Iden

I have a laser engraver that runs on an ESP32 S2 Mini microcontroller. It has the following signature: “Espressif CDC Device” and emulates a COM-type serial port. I had two identical cables; if I connect my engraver to my PC via a serial program (NinjaTerm), I can control GRBL. I cut one of these cables, and they have four wires: VBUS, D+, D-, and GND. After crimping some connectors onto the ends of the wires and testing the cable connected to the port to distinguish between my D+ and D-, Now I’d like to put an STM32F411 (WeAct BlackPill v3.0) between my engraver and my PC to control my homemade Z-axis. The PC side is on a UART port of the STM32 connected to a CH340, and on the engraver side, a USB (D+/D-) CDC Host (Note: I’m not using the USB-C connector already soldered onto the BlackPill). The UART programming side worked perfectly. Where it’s getting stuck is on the CDC side… no response…   #include <stdio.h>#include <string.h>#include <stdarg.h>#include "usbh_cdc

Hello, MCU : STM32C011J4-SO8NBoard : Custom I am working on a Teleruptor and one of the feature is to control relay based on zero crossing due to relay latency.My test code is simple: while(1){ if(HAL_GPIO_ReadPin(ZERO_CROSSING_GPIO_Port, ZERO_CROSSING_Pin) == GPIO_PIN_SET) { RELAY_CTRL_GPIO_Port->BSRR = RELAY_CTRL_Pin; } else { RELAY_CTRL_GPIO_Port->BRR = RELAY_CTRL_Pin; }}I run my system at 3Mhz (Consumption matter) and I see a big clock jitter of (8-10us). Please see image below.Normally, this shouldn’t take more than 1-2us.I tried using EXTI but got the same issue.I tried to run system at 12Mhz and issue is resolved but I can’t. Question:Is this behavior normal at this speed?Is there any way I can reduce the jitter?  Thanks,Ayoub

I posted something the other day; that thread is still open, and I'll close it once I have a solution. I think this information must be out there somewhere because right now it's very limited. Here is the thread: CDC HOSTAs I said, I have no problem with the development boards, but your reasoning means that I might still end up with the same problem in the end. Let me explain. We have 3 chips of the same model but in different packages. This means that the 3 chips have the same functions but a different number of ports.STM32F411CEU6 (UFQFPN48) / Dev Board: Weact Blackpill.
