How do I get a callback function for the HAL_TIM_OnePulse_Start_IT function?I have a STM32G071 Nucleo board.I whish to start a one-shot timer that calls an interrupt callback function when the time has elapsed. For this I have chosen the timer 6 and had the CubeMX, to generate the code:static void MX_TIM6_Init(void) {   /* USER CODE BEGIN TIM6_Init 0 */   /* USER CODE END TIM6_Init 0 */   TIM_MasterConfigTypeDef sMasterConfig = {0};   /* USER CODE BEGIN TIM6_Init 1 */   /* USER CODE END TIM6_Init 1 */ htim6.Instance = TIM6; htim6.Init.Prescaler = 3; htim6.Init.CounterMode = TIM_COUNTERMODE_UP; htim6.Init.Period = 40000; htim6.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE; if (HAL_TIM_Base_Init(&htim6) != HAL_OK) { Error_Handler(); } if (HAL_TIM_OnePulse_Init(&htim6, TIM_OPMODE_SINGLE) != HAL_OK) { Error_Handler(); } sMasterConfig.MasterOutputTrigger = TIM_TRGO_UPDATE; sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISA

Hello - I'm wondering if the STSPIN32G4 can be utilized to drive a brushed motor rather than a three-phase brushless motor that it is marketed for. Alternatively, are there any chips within STMicro that are meant for brushed motors that have a combined MCU and gate driver like the STSPIN32G4?Thank you!-Shane

Hi there,I am just starting touchGFX. I created a project in following steps:create IOC file.. enable touchGFX 4.20.0 , choose display as BW, 128*64, interface:custom, and generate code via STM32CubeMX for STM32CubeIDE.open .part file via touchGFX designer... choose blank templete to import.add widget: text area. Save and generate code in touchGFX designer. go back to STM32CubeIDE, open project. and refresh project.build project... Then I got the compilation error in "../TouchGFX/target/generated/TouchGFXConfiguration.cpp:35:8: error: 'LCD1bpp' does not name a type  35 | static LCD1bpp display;". seems some header file is not included... so the class definition is not included... but I understand from the doc, all these generated files are not supposed to be modified... So I am asking for help: anything I did wrong here? Thanks and Best Regards****

Is there a walk-through or example of how to setup secure boot using a custom device tree?As a side note, the following page returns "Permission Error", is that expected behaviour?https://wiki.st.com/stm32mpu/wiki/STM32MP15_secure_boot

Hi, For example, I create 2 widgets (button and box), the box in top and button in bottom.I need to change their position like picture 2, how can I do except delete and rebuild to changed their order ?  

Hello,When I tried using fseek and getc functions for my project the MP1 failed to execute their code. The execution stops at lines that contain __IO_acquire_lock(fp) and __IO_need_lock(fp) macros and then terminates in the fseek and getc functions respectively. I also tried other file handling functions such as fread and fwrite and they also fail. Is there anyway to solve this issue?thanks for any answers

Hey Guys,So I have this Board and I have a couple of questions:1 - Last week I wanted to connect a sensor to the board, to learn some communication protocol stuff. I noticed that the board PINs (in green) are too close to each other, so, the usual RPi/Arduino Wiring Cables don't really work. I did some research and it turns out that pin configuration was designed to be used with a daughterboard, which I couldn't find, so, I bought 2 connectors - one for the IOs (marked in red) and another one (not shown in the picture) for the Memory PINs (the 2 40-pin columns in between the 60-pin ones for the IOs)The documentation says: Each pin on CN6 and CN7 can be used by a daughterboard after disconnecting it from the corresponding function block on STM32H7x7I-EVAL. They do show a mapping from the controller to the Connectors (CN6 and CN7), but what do they mean when they say: Remove Rxx, close SB xx, Add Rxx, Remove SBxx (see the magenta marked ones). How on earth would I do that?For example: Sa

I'm completely baffled as to how to make DMA and sleep mode work together on an STM32F0. I presume though that the issue is not family specific. It appears when the CPU enters sleep mode via the WFI instruction, DMA stops working. If a busy loop is used instead of WFI, everything works as it should.The following is a piece of code that illustrates the problem. It uses USART1_TX on pin B6 for logging. TIM1_CH1 output is on pin A8.#include <stdio.h> #include <errno.h> #include <libopencm3/cm3/scb.h> #include <libopencm3/cm3/nvic.h> #include <libopencm3/stm32/rcc.h> #include <libopencm3/stm32/gpio.h> #include <libopencm3/stm32/timer.h> #include <libopencm3/stm32/dma.h> #include <libopencm3/stm32/usart.h>   int _write(int fd, char *buf, int len); int _write(int fd, char *buf, int len) { // STDOUT -> USART1_TX (blocking) if (fd != 1) { errno = EIO; return -1; } for (int i = 0; i < len; ++i) usart_send_blocking(USART1, b

Hello everyone, I want to ask how to open a project in stm32cube IDE.To be specific, I was given a project organized as the picture below. The name of the big folder is Project_Comm.While the main code is in Core folder, the linker file and the project file of STM32CubeIDE is in STM32CubeIDE folder. In this case, how can I open the project with the main code and the Linker file in the Project Explorer?What I did so far were:I tried to open the project by the .project and .cproject file from the folder STM32CubeIDE. It only opened the main code in Core folder (the linker file was not there) and I could not build the project.I imported the project by File>Import>Import ac6 System Workbench for STM32 Project. Then I chose the directory containing all of the Folder in the picture above and there were 2 folders: Project_Comm, and Project_Comm./STM32CubeIDE. I chose both of them, each of them but nothing worked. When I chose only the Project_Comm, nothing was imported.Kind regards, Huy

I've stm32H750B-DK discovery board and when debugging I get this error at first debugging attempt , I then press the reset button several times before the download is successful. (pressing the reset button is not guaranteed to solve the problem, I still get the error in this case). Is this a sign of a bigger problem HW or SW?

hi! i am using timer interrup tim3 in stm32f030k6t6, i want configure diferent timer update for 5ms, i am using the ecuation: tout=(prescaler*preload)/(clock_frecuency). other ecuation for preload is : preload=(tout*clock_frecuency)/(prescaler). now for 5ms(0,005s) the preload is: preload=(0.005*48*1000000)/100 , preload=2400, prescaler=100, clock_frecuency= 48Mhz. the timer is configurate with value, the code is:/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2022 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this software, it is provided AS-IS. * *********************************************

Hi,not sure if this is an question regarding ST or Segger, but i will start here:Problem:New Project (my example uses the Nucleo-H723ZG board) with SEGGER_I-CUBE-embOS software package included (like from the wiki.segger.com under Using_I-CUBE-embOS_with_STM32CubeMX )This works fine, but if I enable the Flag "Generate peripherial initalization as pair of '.c/.h' files" in the "Project_Manager/Code_Generator/Generated_Files", the generated code does not include anymore the "OS_Task_Create"-Functions, OS_Stacks and more...Is this a unkown feature? Or can someone help me out?Thanks for your help & best regardsMichael

I'm trying to get into UART interrupt. It used to be copying the 'weak' function declaration and declare our own in main such as:main() { .... void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) {     // usr code here   } .... }  However, this apparently became legacy. Now I get the following:"stm32h7xx_it.c""stm32h7xx_it.c"   **   * @brief This function handles USART3 global interrupt.   */   void USART3_IRQHandler(void)   {   /* USER CODE BEGIN USART3_IRQn 0 */       /* USER CODE END USART3_IRQn 0 */   HAL_UART_IRQHandler(&huart3);   /* USER CODE BEGIN USART3_IRQn 1 */       /* USER CODE END USART3_IRQn 1 */   }  Please advise an App Note describing how we handle the interrupt the same way we used to do.

I am new to TouchGFX and STM32 programming, so I apologize if any obvious details are missed. I am attempting to run Tutorial 2 in the TouchGFX tutorial (Because I'm a new member, I cannot add the link, but it's the TouchGFX Version 4 19 tutorial guide, Tutorial 2)I have successfully run up to "Step 4: Adding Code."I completed up to the step where it asks you to create the "buttonDown" interaction on the TouchGFX Designer (I'm running on 4 19 1).I generate the code without issue, then it asks me to open MainViewBase.hpp (I was trying several screens, so mine is called Screen4ViewBase.hpp). When I add the recommended code to display the "buttonUpClicked" and "buttonDownClicked" text pop up, I hit the "Run Simulation" button on the TouchGFX Designer and the code that I wrote disappears, so the text obviously does not appear. Am I doing something wrong?

We created the project for the M4 with CubeMX. We use FreeRTOS with CMSIS_V2 and OpenAMP as Middleware.We assigned TIM1, TIM2 and TIM3 to the M4 and use TIM1 as SYS Timebase Source.The program runs fine if started with fw_cortex_m4.sh or with the SW4STM32 menu "Run As".But if we try to debug with "Debug As", osKernelStart returns osErrorISR in both Engineering and Production mode. But osKernelStart is in the main function. Also if we create a Mutex it returns NULL. Both functions "fail" on IS_IRQ.This is a very similar question. From there i used the code to read the IPSR, it is already 41 at the beginning of the main function.If i don't initialize TIM1 so that no interrupts from TIM1 can occur IPSR is 14 at the start of main.If i apply the "patch" from this question IPSR is 0 but the creation of RPMsg channels with VIRT_UART_Init fails with:[ 3044.562749] virtio_rpmsg_bus virtio0: creating channel rpmsg-tty-channel addr 0x0 [ 3044.568797] virtio_rpmsg_bus virtio0: channel rpmsg-tty-ch

Any ideas why values would be non linear in the approximately the upper 1 to 2 bits?For the setup below, it is linear to between -17000 to +14000. Doubling the + output only yields around +18000. These are raw values. This really acts like an overflow somewhere it seems to me. Test input is DC, in this case using an AMC3336 TI modulator.What am I missing here?Setup:static void MX_DFSDM1_Init(void) {   /* USER CODE BEGIN DFSDM1_Init 0 */   /* USER CODE END DFSDM1_Init 0 */   /* USER CODE BEGIN DFSDM1_Init 1 */   /* USER CODE END DFSDM1_Init 1 */ hdfsdm1_filter0.Instance = DFSDM1_Filter0; hdfsdm1_filter0.Init.RegularParam.Trigger = DFSDM_FILTER_SW_TRIGGER; hdfsdm1_filter0.Init.RegularParam.FastMode = DISABLE; hdfsdm1_filter0.Init.RegularParam.DmaMode = DISABLE; hdfsdm1_filter0.Init.FilterParam.SincOrder = DFSDM_FILTER_SINC3_ORDER; hdfsdm1_filter0.Init.FilterParam.Oversampling = 256; hdfsdm1_filter0.Init.FilterParam.IntOversampling = 4; if (HAL_DFSDM_Filter

I have the M4 core using a UART core to send and receive data using DMA. This works just fine but over time after 30-60min the core crashes/locks up and reinitializing the UART channel does not help at all it actually crashes the sytem. Under normal operation the reinitialization sequence works properly. The only thing I can get debug-wise is the gState which shows up as 0x21, and the state never changes after the lock-up. Reloading the m4 firmware from a7 side does not help and the UART core is broken until I do a system reboot.Under normal operation, I do get the UART error callback triggered and the error code is 0x10, but the tx and rx continue to work without any action required.Is there any sequence for resetting the UART physical core to recover without a reboot? Are there any known reasons why the UART core would lock up after extended use?
