Hi everyone, I have a STM32F042F6P6 chip. I want to read 9 analog channels on it.I guess there are at least 2 options: configure a scan mode with DMA, and staying in polling mode.I decided to stay in polling mode to avoid a potential problem due to DMA config.I defined 1 adc handle  and did channel configurations (8 first channels are gpios, the 9th is internal temp)It seems that when calling those 2 methods repeatedly, the ADC auto-increments and read each channel starting from the lowest ID.HAL_ADC_PollForConversionHAL_ADC_GetValue Let's say now that I want to have a method that reads only the internal temperature, how do I manage to tell to HAL_ADC_PollConversion to point on the internal temperature channel only ?I have had an idea but it is quite radical:- create other channel config structure, with only the Temp channel defined, and each time I call a conversion method, before that I call HAL_ADC_ConfigChannel with the good channel config structure.Also, I have 2 qu

Hi , I am trying to measure the output return loss ( in tx mode) of my board rf chain which include the stm32wle5.if i understnad correctly - in order to do that i need to put the STM32WLE5  in TX MODE which means its PA should be powered up and ready to transmit but without any transmitted data.  ( so that i will be able to measure the Return loss using external VNA connected to the TX RF PORT of my board)is there an option to do that ?  i cant seem to find a way to make the internal PA ready to transmit (powered up) without actually transmitting .   is it possible to measure the output RL as i described ? thank you,viola

Hi, I'm using an STM32F746bgt6 on a custom board, and I'm using Keil.I enabled LibJpeg in CubeMX, but I can't get an RGB JPEG.I have a .jpeg file saved in flash, "frame99.jpg," which I read via littlefs. When I read it, I allocate the buffer to external SDRAM.int ReadFileSDRAM(lfs_t *lfs, const char *filename) { lfs_file_t file; int res = lfs_file_open(lfs, &file, filename, LFS_O_RDONLY); if (res < 0) { printf("Errore apertura file in lettura\n"); return -1; } lfs_soff_t size = lfs_file_size(lfs, &file); if (size <= 0 || size > SDRAM_SIZE_BYTES) { printf("File vuoto, troppo grande o errore lettura dimensione\n"); lfs_file_close(lfs, &file); return -2; } res = lfs_file_read(lfs, &file, image_buffer, size); if (res < 0) { printf("Errore lettura file errore = %d\n", res); lfs_file_close(lfs, &file); return -3; } uint16_t sample_u = 0; int16_t sample_s = 0; image_size1 = size; while (image_size1 > 0 && image_buf

Hello,I am working with a SOM based on the STM32MP157C and I am trying to bring up a display panel that uses the Sitronix ST7703 MIPI DSI controller.The operating system has been built with Yocto using the BSP provided by the SOM vendor. This BSP is based on Linux kernel 5.4, which unfortunately does not contain the upstream panel-sitronix-st7703 driver.Has anyone already backported the ST7703 panel driver to Linux 5.4 for STM32MP1 platforms? Or does anyone have guidance on how to integrate this driver into an older kernel version?Any hints, patches, or references would be greatly appreciated.Thank you in advance!

Hi,I'm trying to get ADC working on ST32MP257F-DK board. There is no example in ST's sw-package and the example for ST32MP257F-EV1 board fails in HAL_ADC_Init -function giving error messages:stm32_serc_handle_ilac:134 SERC exceptions [63:32]: 0x8000000stm32_serc_handle_ilac:140 SERC exception ID: 59Can somebody help, what is the difference between these boards with ADC? (And why there is no ADC example for ST32MP257F-DK?)

Hello.We are developing a device with the STM32MP257 and we will not have a USB Type-C connector in our design. We plan to use the USB3DR as a USB2.0 device with a USB 2.0 connector to USB boot (USB boot for flashing). Does the STM32MP2 embedded bootloader uses the UCPD CCx signals?How can we inform the USB3DR about detection of the USB VBUS?Is is possible to emulate UCPD CCx signals (sink mode) from the USB VBUS as a variant of detecting the incoming USB power?Best regards,Vadim Aleynikov

Hello Community,I’m facing an issue with Pin PC15 on my board. I am unable to configure or use it as a GPIO, either as input or output. I’ve tried basic initialization, but it doesn’t seem to respond as expected.Has anyone experienced a similar issue with PC15, or is there a special configuration/limitation I should be aware of? Any guidance or suggestions would be greatly appreciated.Thank you in advance!Clock Configuration:LSI at 32 KHzHCLK at 86 MHz

Hello,I have made a custom STM32F412 board, intended for safety applications within various types of machinery.I have completed the hardware and I am now working on the software, which I need some help to organize correctly.Since all applications running on the board are safety related, most of the software is not related to the actual application (type of machinery) being operated.Rather, the majority of the code is running various monitoring and diagnostics routines to ensure that both hardware and software functions as intended; e.g. timing constraints on code execution, monitoring of RAM and Flash memory, etc.All of this "system monitoring" is maintained by me, and must be certified independently. It must not be modified, accidentally or intentionally, by the programmers that subsequently write the code for the specific applications running on top of the system monitoring.For that matter, I would like to statically compile everything, including peripheral configuration, interrupt r

Hi, I am using the following environment:OS: Ubuntu 20.04 LTSSTM32CubeMX: 6.15.0Visual Studio Code: 1.103.2STM32Cube for Visual Studio Code : 3.5.1Board: NUCLEO-H563ZI I found a bug where the STM32H563XX_FLASH.ld file is not generated after generating code.This bug can be reproduced by following the steps below:Create any cubemx project for STM32H563xx.Set "The Toolchain / IDE" to CMake.Click "Generate Code" .After generating code, the files "STM32H563xx_FLASH.ld" and "STM32H563xx_RAM.ld" are generated.However, the CMake build environment requires only STM32H563XX_FLASH.ld. As a result, the CMake build fails and reports the error : "my_project/STM32H563XX_FLASH.ld: No such file or directory" On the other hand, I found that the "STM32H563XX_FLASH.ld" can be generated if "Apply Application Regions Settings to Linker Files: ON" is enabled in Memory Management Tool. 

I followed the setup shown in this video: https://youtu.be/PG50MuFv4KQ?si=daLbNu_JcL2b3U4Q to configure the hardware, but there is no display at all. Could you please tell me why?

Hello,I’ve been working on a project inspired by STMicroelectronics project, where the goal is to identify different operation modes of a power drill — such as drilling, screwing, and idle — using motion sensor data.I’m using one of ST’s development kits (e.g., STEVAL-STWINKT1B) and built my classification model using NanoEdge AI Studio.System Overview:Data Collection:I collected 20 signal recordings per class, each consisting of approximately 200 rows of sensor data.Sensor Preprocessing:The raw data from the accelerometer and gyroscope is passed through multiple filters to improve signal quality:Low-pass filterMoving average filterKalman filterDecision Mechanism (Sliding Window + Majority Voting):To improve classification stability in real-time, I implemented a sliding window with majority voting strategy:A buffer stores the last 50 predictions from the model.If at least 40 out of 50 predictions belong to the same class, that class is accepted as the current state.This helps prevent n

Hello,I am creating a new project on an STM32F4 nucleo board. I configured the X-CUBE-AI library as shown below and specified a TFLite model:When generating code on a fresh project, the "Middlewares" folder is not generated. The project fails to build because the "ai_platform.h" file is missing (it should be in the Middlewares folder). The problem occurs with a fresh STMCubeIDE project and with a fresh STMCubeMX project.I noticed that the "Middlewares" folder is generated correctly once I add additional libraries, such as FreeRTOS. In this case, both the FreeRTOS and the X-CUBE-AI code is generated correctly in the "Middlewares" folder. However, I don't want an RTOS for my application.How can I only generate the code for X-CUBE-AI?Best regards,kahuna

Hello,we are experiencing RAM corruption when running an application in external RAM when setting a breakpoint while debugging.The issue can be reproduced using following configuration:1. Open example STM32Cube_FW_H7RS_V1.1.0\Project\STM32H7S78-DK\Templates\Template_LRUN\STM32CubeIDE\Boot\.cproject in STM32CubeIDE 1.15.0(import both Boot and Appli when asked)2. Build the Template_LRUN_Boot-Project and start it to download the bootloader to internal flash3. Exchange the main.c of the Template_LRUN_Appli with the attached main.c and build the application4. Use STM32CubeProgrammer to download Appli/Debug/Template_LRUN_Appli.bin to location 0x70000000(Connect to STM32H7S78-DK board, click '+' , Open File and select Template_LRUN_Appli.bin, Click Download-Arrow-Down and enter 0x70000000 as Address and Enter to download the Applikation)5. Reset the board - the Led LD1 should be blinking in 1 second interval 6. Attach the debugger to the running application by right-clicking on Temp

Hi, where can I find a working One-Wire protocol? Is there an example provided by STM? I wrote code for a program to detect the temperature from a DS18B20 sensor, but I can’t detect the sensor, even though the debug shows everything is fine. Can someone help me? Thanks

Hi all,I am experimenting with H7 ADC (after having tried the G4 ADC).I see in the HAL that the calibration, HAL_ADCEx_Calibration_Start(), for H7 MCU wants a parameter more than G4. One should specify ADC_CALIB_OFFSET or ADC_CALIB_OFFSET_LINEARITY.I am confused, and reading the datasheet does not help me. Can't understand the difference between the two methods.Should I use ADC_CALIB_OFFSET  or  ADC_CALIB_OFFSET_LINEARITY, when calling the calibration_start()?Or should I call the calibration *twice*, one for each option?TY,linuxfan

Hello,Is there any way i can estimate the Rotor Electrical Angle or Mechanical Angle of a BLDC Motor using sensor-less 6-Step Algorithm in STM Motor Control Workbench.I have tried of using Virtual Position & Feedback but i don't know how to use it as it's .c file is not included in the project.So, it would be great if i can know how to estimate angle!! Thanks!!

Hello,I am using the VENC_USB example from the STM32N6570-DK repository.The example enumerates correctly as a UVC device — I can see the device in Windows Device Manager without any issues.The descriptors in the example are configured for H.264 format only.When I run the demo, the stream is visible in ffplay (so the encoder and USB transfers seem to be working).However, the video is not visible in Windows Camera or VLC. Both detect the device, but no image is shown.My Questions:1.Why is the image visible only in ffplay but not in Windows Camera or VLC?2.What changes need to be made in the UVC descriptors or stream configuration to allow Windows Camera and VLC to properly display the H.264 encoded stream?

Greetings Community,I am using the STHV800 ultrasound pulser in the analog front-end of an ultrasound imaging application. In my setup, I pulse at ±50V, generating a 3-cycle biphasic signal at 5.2 MHz for transmit. The transducer is connected via a 2-meter twisted pair cable; 70-ohm impedance match.I am evaluating potential fault scenarios where:Some transducer elements may be shorted to ground.Some transducer elements may be open.To ensure the safety and longevity of the STHV800 under these conditions, I would like to understand the following:What is the maximum safe voltage I can pulse at without damaging the pulser in these fault scenarios?Does the STHV800 have any built-in protection mechanisms or considerations for handling short-to-ground or open-circuit conditions?Thank you for your assistance!Best regards,Raghavendra Padmanabha

Hi everyone,How can I use the LwIP stack to enable Ethernet on the STM32N6 board? I found a tutorial, but it was for the H5 series. Additionally, I couldn't find the LwIP middleware component in the STM32CubeN6 folder.Thanks in advance!

Hello,   the STM32TrustedPackageCreator supports the obk-file-generation via CLI: STM32TrustedPackageCreator_CLI.exe -obk C:\OBKey.xml   This requires a xml-file. The gui-version allows the generation directly from a password. Is this also possible via CLI?   Best regards, Peter

I saw a strange behavior when using STM32F401RBTx, to show you I added only 1 output as LED and  toggled it.  I have just that much code. I tried with 16 MHz, 48 MHz, 64 MHz, 84 MHz. It went hard fault when speed is 64 MHz or 84 MHz.    This is the clock setting which calculated by STM32CubeIDE.   It goes inside of HAL_RCC_ClockConfig function and can't go beyond HAL_InitTick function. When I put breakpoint inside HAL_InitTick I could delay hard fault little bit and saw below callstack. I tried this with 2 microcontrollers and same thing was happening. How can I solve this? Thank you.  

 Hi,I am working with an STM32F769 MCU driving a 480×272 RGB565 TFT display through LTDC.Architecture:Framebuffer in external SDRAM (IS42S16800F-7TL, 16 MB) connected via FMC.LTDC + DMA2D used for graphics update (TouchGFX).I²C + DMA used to read/write parameters on an external FRAM.System managed with FreeRTOS.Problem:When a long I²C DMA transfer is running (FRAM read/write for parameter storage), I see horizontal glitches on the display: objects temporarily shift to the right (as if some pixels were missing).The curious part is that the phenomenon only happens if I change the initialization sequence in main() from this: MX_LTDC_Init(); HAL_Delay(1000); // avoid flickering on display MX_TouchGFX_Init(); HAL_Delay(200); // avoid flickering on display osKernelInitialize();…to this:MX_LTDC_Init(); HAL_Delay(1000); // avoid flickering on display MX_TouchGFX_Init(); HAL_Delay(200); // avoid flickering on display __NOP(); // added __NOP(); // added osKernelInitialize();adding only
