Solved

Hello ST team, I have established communication with the TOF while using the Full library（The example file used is STSW-IMG015 VL53L3CX_BareDriver_1.2.10.） of VL53L3, and I successfully read the ID (which should prove that my I2C communication is normal). However, no matter what I do, I cannot obtain the ranging data. After studying the example program, I realized that I did not connect the interrupt line in my hardware setup (I’m not sure if this is the cause of the issue).My system's power supply is 2.8V.I don’t want to use the interrupt pin to control or retrieve the TOF’s status, as it would occupy an IO port on the MCU.Below are my initialization function, Read function, and the data printed via the serial port. This issue has been troubling me for days, and I really don’t know how to resolve it.Wishing you a happy day.void VL53LX_Nomal_init(void) { VL53LX_Dev_t ndev; VL53LX_DEV Dev = &ndev; uint64_t byteData; uint16_t wordData; uint8_t status; Dev->I2cHandle = &h

All of a sudden,  I cannot connect to this board via stlink usb cable.  I tried pressing reset button, updated firmware, connect in every possible mode (hardware reset, core reset).  Is there a combination/sequence of pressing buttons? In other stm32 mcu I saw  a way to erase memory by connecting a resistor to reset pin and  ground momentarily.  Can this be done on this board and how?   Anything else i can try before I trash it?   Thank you for your help!

Hi there, I'm configuring CAN filtering for STM32Hxxx. I have several filters configured. Currently, when CAN Frame match filter it is not going through other filters.Is there a way to change filtering behavior to hit all filters that match given pattern not the first one only. 

Hi everyone,Im  pretty new with using stm32.Im trying to debug and make printf output to the log. I found alot of vidoes but got pretty lost. Im confused about what is the way of doing it from the start.  I need to setup the external clock?Then the  trace asynchronous Sw?  Any explaination would be amazing, thanks! 

The GPIO clock is the only code that seemed to be generated under the initialization function. the other necessary code such as the following was not created. GPIO_InitTypeDef GPIO_InitStruct; GPIO_InitStruct.Pin = GPIO_PIN_8; GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);In the setup GUI I had selected the pin PC8, and set it to a GPIO_Output yet the above code was not generated.

I'm trying to read a .JPG image file from my SD Card (FATFS) and want to use LIBJPEG for decoding it. Everything seems to be fine until I execute the **jpeg_start_decompress()** function. As soon as this ifunction is executed a UsageFault is generated on the MCU, does anyone know why would this be happening?Here is my code for loading the jpg image: void read_JPG_image(FIL* _fptr, uint32_t _width, uint8_t* buff){JSAMPROW buffer[2] = {0};uint32_t row_stride = 0; buffer[0] = buff; cinfo.err = jpeg_std_error(&jerr); jpeg_create_decompress(&cinfo); jpeg_stdio_src(&cinfo, _fptr); jpeg_read_header(&cinfo, TRUE); cinfo.dct_method = JDCT_FLOAT; jpeg_start_decompress(&cinfo); row_stride = _width * 3; while (cinfo.output_scanline < cinfo.output_height){(void) jpeg_read_scanlines(&cinfo, buffer, 1); // put_scanline_someplace;}jpeg_finish_decompress(&cinfo); jpeg_destroy_decompress(&cinfo); f_close(

I'm a software developer and love electronics, specifically making metal detectors. I'm trying to develop a new Pulse Induction metal detector and I'm using this development board (STM32F407VET6).Although I'm a software developer, I work with high level programming languages like Javascript and Python, so programming in plain C (register manipulation) is not easy for me, but I want to learn, so, I'm building the code with the help of AI (ChatGpt).The code below is supposed to generate 2 pulses with PWM inside a 1ms pulse period. One pulse is 100us (or the metal detector TX pulse) generated to PE13 and another is 500us (for the metal detector power supply charge pump) generated to PA8.I tested the pulse generation with an oscilloscope 100uS/Div and the first pulse is correct (100us) but it appears one time at the start and another at the end of the and it should appear only one time at the start of the period. I tried everything with the IA but I can't solve this problem and don't under

Hey everyone :waving_hand:,After installing STM32CubeIDE, I encountered the following warning:"This peripheral has no parameter to be configured"At first, I thought it was an error — but after doing some research, I realized it's probably nothing serious.However, to be sure, I tried everything I could:Reinstalled STM32CubeIDEChanged system settingsUpdated all available packages and toolsDespite all of this, the warning still appears whenever I configure certain peripherals.Can someone help me understand if this is normal behavior? Should I ignore it, or is there a proper way to fix or suppress this warning?Any guidance would be greatly appreciated!Thanks in advance!

Hi, I am Driving an AMOLED display (GRAM) with QSPI.In blocking mode everythings works fine, but now I trying to "update" it using GPDMA, nothing works.

Hi All, I need to obtain an artifact with the name present in some costant in "main.h". In other words, my project is called "TestProject" and main.h I have these costants: #define GUI_MAJOR_VER 0 // Major #define GUI_MINOR_VER 1 // Minor #define GUI_RELEASE_VER 3 // Release I would like to ahve a final executable named "TestProject v013.hex" This means that every time I will change the #defines in main.h, output file will change automatically with a new numeration. Does someone has some suggestion? or better, an example? thanks in advance for your help.    

I'm working on a project that will be using shared code files from outside the project.  I do not want to copy them, instead I want to link to them.  I discovered how to do this and it works well.  Since I don't want to make any changes to any of the linked files, I would like for the IDE to somehow make easy for me to know that the file I am currently viewing is a linked file.  I have not been able to find a way to do this with CubeIDE.  Does anyone know of a way?  Thanks

I have a problem with identifying the sensor type from the marking on the housing. One is LSM6DSO32XTR and the other is ASM330LHHXTR. Unfortunately they came in a bag without a description on the label. One is marked T3 [QR code] 233 and the other LC [QR code] 307.Is there a way to identify them without attaching them to the board? Unfortunately the datasheet did not help.Thanks

Hi everyone,I plan to build 0-60 volt 30 Amps adjustable (menu driven) lab power supply both ac and dc(battery) inputI'm new at st mcu and need some advise about choosing right device both controller and user interface.thanks inadvance.    

Hello,For my project Im checking on a data request by using DMA and UART Idle interrupt. After a few minutes my while loop just stops executing. The code keeps executing the USART1_IRQHandler and doesn't return to the main code anymore. If Im not using DMA this doesn't happen. Does anyone know how this happens and if it can be fixed?Here a few code snippets:static void MX_USART1_UART_Init(void) { /* USER CODE BEGIN USART1_Init 0 */ /* USER CODE END USART1_Init 0 */ /* USER CODE BEGIN USART1_Init 1 */ /* USER CODE END USART1_Init 1 */ huart1.Instance = USART1; huart1.Init.BaudRate = 230400; huart1.Init.WordLength = UART_WORDLENGTH_8B; huart1.Init.StopBits = UART_STOPBITS_1; huart1.Init.Parity = UART_PARITY_NONE; huart1.Init.Mode = UART_MODE_TX_RX; huart1.Init.HwFlowCtl = UART_HWCONTROL_NONE; huart1.Init.OverSampling = UART_OVERSAMPLING_16; huart1.Init.OneBitSampling = UART_ONE_BIT_SAMPLE_DISABLE; huart1.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_NO_INIT; if (HAL_RS485Ex_Init

I want all versions of cube ide and cube mx. can you please provide the links of that.

I am using STM32F407VG in my project temporarily. The objective is to transmit audio data over ethernet which is received in this mic and received audio from the other end this side having stm32 as the MCU.  For Mic, I am using SPH0645. But I am unable to sample the audio correctly. I am facing the same issue as in the following link. https://community.st.com/t5/stm32-mcus-products/unexpected-behaviors-in-dma-buffer-for-i2s-mems-microphone/td-p/725679my_code:uint16_t data_in[100] = { 0 };volatile int16_t sample_i2s;void HAL_I2S_RxCpltCallback(I2S_HandleTypeDef *hi2s) {sample_i2s = data_in[0];}int main(void){/* USER CODE BEGIN 1 *//* USER CODE END 1 *//* MCU Configuration--------------------------------------------------------*//* Reset of all peripherals, Initializes the Flash interface and the Systick. */HAL_Init();/* USER CODE BEGIN Init *//* USER CODE END Init *//* Configure the system clock */SystemClock_Config();/* USER CODE BEGIN SysInit *//* USER CODE END SysInit *//*

Hello,I am currently evaluating STM32s for use in professional developments.I'm going to substitute them for Microchip's AVR DB family microcontrollers.I still have one point to evaluate: is there an EEPROM built into the STM32s that allows parameters to be saved?Thanks for your clarifications

Hi All, 1 - HAL_QSPI_MODULE_ENABLED is defined and the shaded code areas are combiled. But I could not find why these codes seems shaded, do you ?2, 3 - I can see file icon on the top left corner of the stm32h7xx_hal_conf.h file name and context menu shows absoulte path when mouse over while other files path seems relative to project directory. Do you know why ?Regards. 

Hi, while using the SVD (Version 1.8 - but in the 1.9 zip this file still states 1.8) for the H743 I noticed some errors and have patched them for my code generation. Some of them caused me trouble for hours until I noticed that the SVD and the RM did not agree.I'll attach the patches here. I tried to attach the patches here, but .patch is not accepted, renaming it to txt still fails...Fixes for the CAN module: https://pastebin.com/1X0v7iS4Fixes for the TIMER module: https://pastebin.com/rTEP4M3WFixes for the ADC module: https://pastebin.com/ED99CUTBFix for one TIMER interrupt: https://pastebin.com/cvnEj1MW 

@STTwo-32, I also noticed issues in the EXTI.Sample:stm32h7s7xx.h,   &(EXTI->PR1) == 0x58000088STM32H7S.svd, &(EXTI->PR1) == 0x58000020When should we expect the upcoming release (in 2 month?)?Also, are there public script which validate that stm32*.h and .SVD do match?
