Currently, STM32Cube for Visual Studio Code introduces a new bundled package manager which replaces STM32CubeCLT.However, when developing STM32 projects with other IDEs (e.g. CLion), STM32CubeCLT is still required to provide the build environment.This leads to several problems when using multiple IDEs (VS Code + CLion):Separate installations of toolchains (STM32Cube for VS Code and STM32CubeCLT) consume extra disk space.STM32CubeCLT cannot be updated incrementally; users must download the whole package.STM32Cube for VS Code currently cannot manage STM32CubeCLT packages, leading to duplicated toolchain management.By default, tools are installed on C:\ drive, which is inconvenient for users with limited system disk space.Feature request:Allow STM32Cube for VS Code’s package manager to use and manage STM32CubeCLT packages.Benefits:Reduce disk usage by avoiding duplicated toolchains.Simplify updates and package management.Improve developer experience when using multiple IDEs (VS Code + CLi

Hello everyone, I have designed a custom PCB using the STM32L031K6 microcontroller. The board includes an external 32.768 kHz crystal oscillator (LSE - Low Speed External). The Problem: I am flashing code to the board using an ST-Link. When running a simple LED blinking application (which uses HAL_Delay), the LED either blinks only once or gets stuck indefinitely within the HAL_Delay function. This strongly suggests an issue with the microcontroller's clock configuration or the LSE activation. Hardware and Code Details: MCU: STM32L031K6 External Oscillator: 32.768 kHz (LSE) Development Environment: STM32CubeIDE Library Used: STM32Cube HAL Problematic Function: HAL_Delay() (This function relies on a properly running clock source, usually SysTick). I will attach the following: S

Hello community,I am running in an issue with the VREFINT calibration value of the ADC.For calculation I use the __LL_ADC_CALC_VREFANALOG_VOLTAGE function from the stm32u0xx_ll_adc.h file and I'm getting wrong values.The Chip is powered with 3.3V and so I expect a reading of approx. 3300 from this function, but what I'm getting is a value of around 2993.The measured voltage at the VDDA/VREF+ pin (48-pin package) is 3.296V, the reading of the VREFINT Channel is approx. 1660.If I change the supply voltage to 3V, I get around 1820 from the VREFINT Channel.The readout of the VREFINT address (0x1FFF6EA4) is 1654 (0x0676) so point 2.1.2 of the errata sheet is not applicable.If I change the value VREFINT_CAL_VREF in stm32u0xx_ll_adc.h from 3000UL to 3300UL the return values are plausible.For me it looks like the calibration was done using 3.3V instead of 3.0V as stated in the datasheet.The marking of the controller reads likeSTM32U073CCT6CQ27C 9R ACHN 435 1M (or LM)Can anyone confirm or is th

I try to understand in details the way the Hash peripheral works on the STM32L552. I need to make the HASH SHA-256 with 224 blocks of 512 bits. The Hash works perfectly until the block 223. Then I enter 16 values in the FIFO (in my code below I have a loop for 15 because I entered previously another value). Then I launch the final digest. I expect the automatic digest of block 224 and the automatic padding in a block 225 to the final hash value. But I always have the wrong value in the final step. Any idea about what I'm missing? 

I would like to read some data from the EEPROM on initialization to use in the TouchGFX application.I currently have an API that can request read/write operations from TouchGFX to the backend.At the moment, I've implemented it in the Model.hpp void bind(ModelListener* listener) { modelListener = listener; if (!storageInitialized) { initializeFromStorage(); storageInitialized = true; } }withvoid Model::initializeFromStorage() { #ifndef SIMULATOR StorageResponse_t wr = Storage_Request(STORAGE_CMD_READ, EEPROM_ADDR_STRUCT_2, &struct2, sizeof(struct2)); wr = Storage_Request(STORAGE_CMD_READ, EEPROM_ADDR_STRUCT_1, &struct1, sizeof(struct1)); #endif }but I'm not sure if it's the correct location.I just want to send the read EEPROM command on the first load of TouchGFX and never again

In the above image (logic analyzer) , SPI in DMA was supposed to start at the end of high on the second signal, but it starts a bit later. (3rd signal CS of SPI, 4th signal SCLK)And the SPI was to supposed to be active at every period (the first signal) whose period is 8.607us. The second signal is a slave timer to the first and a period elapsed callback of this signal call HAL_SPI_Receive_DMA.There is also a 1 second timerWhat should i do to correct this? I don't how to proceed, any solutions, learning materal would be really helpful

We are pleased to announce that STM32CubeIDE 2.0.0 release is available. STM32CubeIDE is now independent from STM32CubeMX. With this release, device configuration, previously handled within STM32CubeIDE via STM32CubeMX, is now exclusively available through the stand-alone STM32CubeMX tool. Users will configure microcontroller peripherals and generate initialization code separately in STM32CubeMX, then import the generated projects into STM32CubeIDE for coding and debugging.   STM32CubeIDE, is now a stand-alone tool, offers the possibility to create empty project through its own MCU/Board selectors now present inside. What does this change mean for developers?  Separate download and installation: STM32CubeMX is no more integrated in STM32CubeIDE, requiring separate download alongside STM32CubeIDE 2.0.0 for configuration and code generation.  Tool update flexibility: Developers can update and freeze&n

Could it be time for ST to reveal such an MCU at the summit in a few weeks? Or maybe a Cortex-M55 that actually have integrated flash or MRAM or similar? (STM32N6 is interesting, but I would like to see flash/MRAM/something else integrated...

When using PLL3Q as input with a frequency of 32MHz for USBPHY I have a RCC_CCIPR1 register initialized at value 0x2a00 when entreing USB_CoreReset function that is not correct (should be 0x2b00).

I would like to use the STM32WL33 as a radio receiver and continuously transfer all I/Q samples to my computer for further processing.Also, I want to use the highest possible IQ sampling rate (CHF_E = 0,  500k IQ samples per second = 64 Mbit/s).I've managed to configure it to IQ receiver mode, have it write samples to the databuffers in RAM and output the buffers via USART once both are full.However, I want to record more samples than would fit in the RAM and thus I have to somehow output the buffers faster than they are filled (or equally fast)This is where I've encountered a bottleneck. None of the STM32WL33's interfaces (SPI/USART/I2C/...) can transfer data fast enough, the highest I found is SPI with 32 Mbit/s. So how can I output 64 Mbit/s worth of samples?My idea would be bitbang a parallel interface on the GPIO ports and use another MCU (with a higher clock rate) to convert it to USB or some other serial interface. However, I'd like to know if theres a better way to ac

Hello. I'm working with STM32H573. I have a question related with the use of STSAFE-A110 for TLS. I have to authenticate also the client. I've succeded stablishing TLS mutual authentication with HTTPS server and TCP server  (different applications, not related) using this type of functions from NetxDuo with the correct data and test certificates: /* TCP Server */ nx_secure_tls_session_create(); nx_secure_tls_ecc_initialize(); memset(&certificate, 0, sizeof(certificate)); // Server Local certificate nx_secure_x509_certificate_initialize(); memset(&certificate_, 0, sizeof(certificate_)); // Client certificate nx_secure_x509_certificate_initialize(); nx_secure_tls_local_certificate_add(); nx_secure_tls_trusted_certificate_add(); nx_secure_tls_session_start(); /* HTTPS */ memset(&certificate, 0, sizeof(certificate)); // Server Local certificate nx_secure_x509_certificate_initialize(); memset(&certificate_, 0, sizeof(certificate_)); // Client certificate nx_secure_x

I have the STM32F401RE NUCLEO-64 Board and have gone over and over all the instructions but I must be missing something because my board doesn't seem to be read by my laptop. I have everything the way it says on the manual and elsewhere. I have the jumper JD1 off, The other 2 JD's are on and i don't get any reading on my laptop. It doesn't show up anywhere. Not on the ide or the mx programs. Nowhere. If anyone can please help and tell me what I'm doing wrong i really appreciate it. I am connected using a usb to micro i Believe it is or the micro b. Teh one red led stay on  the upper right one flashes red and the green led flashers and goes faster or slower depending on when i press the blue button. Thank u

It would be great if the STM32CubeProgrammer would do proper error handling for J-Link debug probes instead of crashing.Issue:Every times I try to the connect to a STM32 target that is not powered, or not properly connected the GUI pops up three error messages that need to be close separately and on the next connect it pops up another error message and gets stuck. So that the program needs to be completely restarted. Preferred behavior:STM32Cubeprogrammer show only a single pop up or only log a warning message and recovers from this situation in a way that that allows it to connect to a STM32 target again. This is no regression and has been observed since j-link probes are supported.The last time it has been observed is on a Windows 11 PC with intel CPU, targeting a STM32G4 MCU with STM32Cubeprogrammer v2.21.0, J-Link HW version V11.00(latest FW Apr 1 2025) 

Hello,I am working with the STM32WL55CC (48-pin package). When I imported the official STM32CubeWL example projects from ST, I noticed that they provide both SINGLE CORE and DUAL CORE versions. But the board that these examples are listed under STM32WL55JCIX, which itself is a DUAL CORE device.However, when I create a new project in STM32CubeIDE for the same device (STM32WL55JCIX), CubeIDE always generates a Dual-Core project structure (with CM4 and CM0+ folders). There is no option to generate a Single-Core project, even though the example projects clearly include one.Also, the file structure of the official examples is very different from the structure generated by CubeIDE. Following the tutorials, example projects contain folders like Application/, Utilities/, and files like se-identity.h, But I am not able to find "se-identity.h"Since I am developing for the STM32WL55CC (48-pin) variant, I am having trouble understanding how to properly port the example code (which i

Im using STM32F411E-Discovery (MB1115D) for my project and i need to power it from an external supply instead of USB. I have a external 5V supply but not sure how plug it in, should i inject 5V directly into 5V pin and ground to GND on 25x2 header? 

Dear all!i'm try to set up STM32H562RIT6 project, i use STM32cubeMX6.4, but it seem didn't support, i try to instal H5 package but still can't find MCU. some one know how to fix it, pls help me

As shown in the figure, the title of the window bar seems to have become garbled, even though its content was originally in English. I thought it was due to the software defaulting to a font that only supports Western characters, but changing all the available fonts did not solve the garbled text issue. Please help me; this is very important to me. Thank you so much!If there are similar problem cases, please send me the solutions along with them

Hi All,I have been working with the STM32H7R7 MCU for a while.  I used the getting started manual of the application notes for Eclipse, but I could not set up the right debug environment for the STM32H7R7 deviceI used the cubemx to generate the boot, appli and ext memory. I used exactly the same ioc file (except the setting of the cmake vs cubeide), however I could not flash and debug the device without the right json file.I tried to build by myself, but I was not lucky enough to be succesfull. Also I have not found any examples on the web.Could somebody help me with a json file, environment for debug and flashing? Thank you very much in advance

Hi. I'm looking for a programmer for SPC564L60L5. The best would seem SPC5-UDESTK but it is not available for sale. Or maybe StellarLINK It will be ok for full programming and debugging support for this chip. Or maybe some other suggestions of a programmer who would support SPC564L60L5?  Thank you for your help Best regards Christopher   

Hello, Using Modbus master and slave communication, where Modbus master working fine, I have issue with slave device communication. Using HAL_UARTEx_ReceiveToIdle_IT() for receiving modbus frame, and HAL_UART_Transmit_IT() to transmit response. Currently doing only read for testing purpose. Issue: LPUART does not wakeup on receive interrupt. Here is the information below During Init() #define LPUART1_EXTI_ENABLE_IT() (EXTI->IMR1 |= EXTI_IMR1_IM28) LPUART1_EXTI_ENABLE_IT(); __HAL_RCC_WAKEUPSTOP_CLK_CONFIG(RCC_STOP_WAKEUPCLOCK_HSI); __HAL_RCC_HSI_ENABLE();   And here I will go to sleep mode if no rx/tx going on. So I will maintain the state busy until rx to tx process is complete. Once it complete, it will go to sleep mode. Here below is sleep mode logic //Preparation for next receive data RS485_RX_ENABLE();//Its macro to receive RX data on line. __HAL_UART_FLUSH_DRREGISTER(&hlpuart1); HAL_UART_AbortReceive(&hlpuart1) HAL_UARTEx_ReceiveToIdle_IT(&a

I am using the STM32 NUCLEO-G474RE control board and the NUCLEO-IHM08M1 inverter board for a motor-control application. I want to run a 6-step (trapezoidal) commutation algorithm, so I need to generate PWM signals from the control board to the driver IC on the power board(NUCLEO-IHM08M1).The driver IC (L6398) truth table specifies:HIN = 0 and LIN = 0 → Low-side ONHIN = 1 and LIN = 1 → High-side ONBut the STM32 timer provides complementary PWM outputs, where each channel only gives PWM + its inverted output, so it does not match the L6398 input logic. With complementary channels, the outputs are only HIGH or LOW for PWM—they cannot give “both HIGH” or “both LOW” on the same phase simultaneously as required by the driver.Therefore, I need guidance on how to generate the correct 6-step commutation sequence for the IHM08M1 board using the NUCLEO-G474RE, given that the L6398 requires both HIN and LIN to be controlled independently.

Hello, The datasheet doesn't seem to mention the function the tab on the back of the IC. Can I connect it to GND to thermally conduct the heat out?  Thanks

When sliding the screen in TouchGFX, some widgets may experience rendering issues causing flickering. What could be the root cause, and are there any solutions?The images are all in the external QSPI Flash. Could this be the reason?

I'm working with an STM32F411 and trying to run two I2S master-receiver interfaces (I2S1 and I2S2) at the same time, each receiving data from a pair of PDM microphones using DMA circular transfers.However, I found a very strange and extremely hard-to-debug issue:Observed abnormal behaviorWhen only one DMA is enabled, both I2S1 and I2S2 work correctly.When both I2S + DMA are enabled at the same time, the following happens:If I2S1 has no microphone connected, it correctly receives all zeros.If I2S2 does have a microphone connected, then I2S1 suddenly starts receiving non-zero data, even though no microphone is connected to I2S1.It looks like I2S1 is receiving data that actually belongs to I2S2’s DMA buffer.Sometimes the behavior changes depending on the order of calling HAL_I2S_Receive_DMA().Both DMA buffers are allocated as global arrays (4 × 512-word buffers).I also tried disabling JTAG on PA15 (I2S1_WS), but the issue still exists.DMA configI2S1 RX → DMA2 Stream2I2S2 RX → DMA1 Stream3
