I've interfaced the VL53L4CD with ESP32-S3, but I'm unable to get accurate ranging values below 70mm.I'm using the ESP32-S3 with Arduino IDE.How can I resolve this issue ?#include <Wire.h> #include "vl53l4cd_class.h" #define SDA_PIN 8 #define SCL_PIN 9 VL53L4CD sensor(&Wire, -1); // -1 = XSHUT not used void setup() { Serial.begin(115200); delay(1000); Wire.begin(SDA_PIN, SCL_PIN); Wire.setClock(400000); Serial.println("VL53L4CD Init..."); if (sensor.begin() != 0) { Serial.println("VL53L4CD not detected"); while (1); } Serial.println("VL53L4CD detected"); sensor.VL53L4CD_SetRangeTiming(50, 0); // 50ms timing sensor.VL53L4CD_StartRanging(); } void loop() { uint8_t dataReady = 0; VL53L4CD_Result_t results; sensor.VL53L4CD_CheckForDataReady(&dataReady); if (dataReady) { sensor.VL53L4CD_GetResult(&results); sensor.VL53L4CD_ClearInterrupt(); Serial.print("Distance: "); Serial.print(results.distance_mm); Serial.println(" mm"); } delay(20);

Dear Community,I have a general question. I wanted to use C++ classes in SPC5 Studio to get a cleaner project structure.For this, I changed main.c to main.cpp and included the C headers using extern "C". I also enabled the C++ linker in the Platform Component RLA.The project builds without any issues, but the parsing errors in the editor are extremely annoying. A lot of the code is marked in red even though it compiles fine.Does anyone know what setting I need to adjust to get rid of all these unresolved reference errors in the parser (i presume...)?Kind regards,TKorn

Hello, i just wanna take a snapshot by STM32N6570-DK with IMX335. I am using SnapshotDecimation as my reference. after reviewing the code. i wonder why AXI RAM3/4 and RIF are necessary for this project i saw it in 'HAL_DCMIPP_MspInit' function, but i didnt found anything about AXI RAM in other parts of the code.anyone can explain why does axiram necessary for this project?void HAL_DCMIPP_MspInit(DCMIPP_HandleTypeDef* hdcmipp) { RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0}; RAMCFG_HandleTypeDef hramcfg = {0}; RIMC_MasterConfig_t RIMC_master = {0}; if(hdcmipp->Instance==DCMIPP) { /* USER CODE BEGIN DCMIPP_MspInit 0 */ /*** Enable peripheral clock ***/ /* Enable DCMIPP clock */ __HAL_RCC_DCMIPP_CLK_ENABLE(); __HAL_RCC_DCMIPP_FORCE_RESET(); __HAL_RCC_DCMIPP_RELEASE_RESET(); /*** Configure the NVIC for DCMIPP ***/ /* NVIC configuration for DCMIPP transfer complete interrupt */ HAL_NVIC_SetPriority(DCMIPP_IRQn, 0x07, 0); HAL_NVIC_EnableIRQ(DCMIPP_IRQn

i have been trying to find ways of converting my stm32f103 board to stlink for a personal project , i  have found out i need to flash the st link firmware onto this chip but i am not really able to understand how to flash this on the board , if someone has any way to do this it would a huge help , i cant really do anything else as i have already printed a pcb for this purpose so if any one has any way to flash the stlink firmware onto the f103 chip it would be huge help  ? the board is stm32f103CBT6 (64KB FLASH + 20KB RAM ) 

I want to know what computer vision is and what are its real world applications. 

The X-CUBE-AZRTOS-H7RS middleware is missing the setting to change the USBX System Stack Size which in turn means that the USBX_MEMORY_STACK_SIZE define in the app_usbx.h file can not be changed from its default of 1024. And because the define is not in a USER CODE section, any manual change will be overridden when re-generating code in CubeMX.Here is an example when using USBX host stack, but it's the same for the device stack.STM32H7RSxx:STM32H7A3ZIT:  

Hello,I'm having trouble deploying the middleware for the X-NUCLEO-NFC12A1 demo board.I have an x-NUCLEO-NFC12A1 and a NUCLEO-WBA65RI.I connected the two boards together, wired the pins correctly, and tried to use the X-CUBE-NFC12 middleware package. However, when I generate the project, it only includes the ST25R500 driver under Drivers/BSP/Components/.How can I get a proper starting point to develop with the ST25R300? Is there a specific package or example project available for it?My goal is simple: I want to use it to enable and operate a WLC with a PTX30W.Thanks a lot for your help,Yvan

Hi everyone,I'm currently porting the App of STM32U5 SBSFU example to CubeMX and "smooth" is not the word I would use to describe the process.Namely, the SBSFU example includes Bootloader, Loader and App projects with memory map being in separate centralized header files included by all these projects. These files (region_defs and flash_layout) are not fully polished (some bugginess and inconsistencies) but they do ease the memory management a lot by using defines and not hardcoding; these defines are then used in projects' linker files in order to define memory regions.In contrast, CubeMX just provides a UI representation of the memory space where users can input all the memory bounds, be it flash or RAM. The trouble is, we can only enter numbers and not constants, so generated code is full of hardcoded address bounds.This does not play well with SBSFU Example - since these address bounds are not only used in LD files, but rather for defining FLASH areas, SAU regions etc etc, it is an

Hi, I am trying to establish CAN communication between three different MCUs: NUCLEO-H723ZG, NUCLEO-H755ZIQ, and NUCLEO-G474RE. However, I am unable to successfully communicate between the boards, even though the same baud rate has been configured on all MCUs. I have also connected an external CAN transceiver to each board for proper CAN bus operation. On the NUCLEO-G474RE, I have enabled UART4 to send command data, using the following pins: PC11 – UART4_RX PC10 – UART4_TX Clock Frequency [SYSCLK] & Baud Rate [CAN]: 1. NUCLEO-H723ZG: 550 MHz     Baud Rate: 500000 Bit/s     2. NUCLEO-H755ZIQ: 480 MHz     Baud Rate: 500000 Bit/s     3. NUCLEO-G474RE: 170 MHz     Baud Rate: 500000 Bit/s    

Probably this is trivial, but I just cannot find it.How to deploy image using CubeIDE for VS Code without debugging?How to properly configure Build+Deploy only (no debug) task in tasks.json file?How to configure Build+Deploy with debug task?Should I use cube cli for that or there is some easier way?

Split from the Implementing a LwIP and FreeRTOS™ v1 UDP echo server on the STM32F7 series Tutorial;Moved to the forum for better visibility & discussion.@mƎALLEm Hi Sir,I am using the same code that works correctly on the development board. However, when I run the same firmware on the custom board, I am encountering an error.Is there any issue in the schematic related to Ethernet?Can I use the same libraries that are used in the Nucleo-H755ZI-Q board for this LAN?If I use the same library and it gets stuck at netif_add() what could be the issue?

Hi, I am using CubeMX 6.16.1 to work on a STM32F777ZIT6 target. However, the generated code does not have the Macro definitions of the GPIO pins in main.h. The GPIO init part IN MX_GPIO_Init() is also empty, as follows:/** * @brief GPIO Initialization Function * None * @retval None */ static void MX_GPIO_Init(void) { /* USER CODE BEGIN MX_GPIO_Init_1 */ /* USER CODE END MX_GPIO_Init_1 */ /* GPIO Ports Clock Enable */ __HAL_RCC_GPIOE_CLK_ENABLE(); __HAL_RCC_GPIOF_CLK_ENABLE(); __HAL_RCC_GPIOH_CLK_ENABLE(); __HAL_RCC_GPIOC_CLK_ENABLE(); __HAL_RCC_GPIOA_CLK_ENABLE(); __HAL_RCC_GPIOB_CLK_ENABLE(); /* USER CODE BEGIN MX_GPIO_Init_2 */ /* USER CODE END MX_GPIO_Init_2 */ } I also tried CubeIDE 1.19.0, have the same issue.Did I do anything wrong? I think it is really important to get this function work, as it would be cumbersome to manually init the GPIO pins. I attached the .ioc file, thanks in advance for your help.Thanks,Xiankun

Hello,I am working on the stm32mp257f-ev1 board and attempting to switch from the default USART2 early crash console output to USART6. I've successfully switch TF-A and U-BOOT console to USART6 but my OP-TEE console continuously outputs on USART2.I've made sure to change the serial0 alias from USART2 to USART6 in the OP-TEE device tree (as I've successfully done in the TF-A device tree) and I've also followed the directions to change the header file stm32mp2_def.h For USART6, I've changed the early crash console in stm32mp2_def.h to the following:#define STM32MP_DEBUG_USART_BASE                    USART6_BASE#define DEBUG_UART_TX_GPIO_BANK_ADDRESS    GPIOF_BASE#define DEBUG_UART_TX_GPIO_BANK_CLK_REG     RCC_GPIOFCFGR#define DEBUG_UART_TX_GPIO_BANK_CLK_EN        RCC_GPIOxCFGR_GPIOxEN#define DEBUG_UART_TX_GPIO_PORT                     

On AN4879, STM32N6 is marked as Type E (Universal serial bus full-speed host/device interface) But actually it has 2 HS OTG with phy as high-end line up (2* Type D)  

Hi! I’m starting design of a new board, on which I’d like to use an stm32h7 device. My board will also include an audio codec and usb hs phy.Historically I’ve used crystals to drive HSE of the mcu, but some reference designs I’ve been studying show the use of cmos oscillators to drive the clock. I am curious about the trade offs of this, or how/when I should prefer a crystal over an oscillator?thank you!

Hello,I am returning to STM32 development after about two years and I am preparing a new project that will handle multiple tasks using several peripherals.I have installed STM32CubeIDE version 2.0.0. The installation completes without errors, and I am able to create a new STM32 project. However, after the project is created, the .ioc file does not open

Hi!In version 4 of the reference manual for STM32U0, it is suggested that BOR is enabled and on Level 3 from the factory.Is that correct?I'm currently working on an construction running @ 2V, so it would never start up, if so. And when I read out the Option Bytes on a new MCU, BOR is disabled? https://www.st.com/resource/en/reference_manual/rm0503-stm32u0-series-advanced-armbased-32bit-mcus-stmicroelectronics.pdf

I have some text that should not be translated.If a translation field in the table is empty, is there a way to make it automatically display the text from the first translation box, instead of having to copy and paste the same text into every box?

I have been using PE micro Multilink FX for several years, but its Linux support is terrible. Is there a ST (or another) alternative with this functionality compatible with stm32CubeIDE? I just need to supply power (up to 100 mA at 3.3V) to my board for debugging. I don't need high tracing performance or anything like that. Thanks in advance,Gaston

In STM32CubeCLT (including latest 1.20.0 version), there is CMake but no make.To build projects from CubeMx gererated make projects, I have to install STM32CubeIDE and add below into PATH.  C:\ST\STM32CubeIDE_2.0.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.make.win32_2.2.0.202409170845\tools\bin Manually install standard GnuWin32 Make is not enough because it miss some additional tools such as rm.exe, mkdir.exe ...

Hello, rm0456 in chapter 33.4.8. talks about "Software procedure to calibrate the ADC" and "Extended calibration mode" on some products. It is not clear, if "Software procedure to calibrate the ADC" is enough for products with "Extended calibration mode" or  if extended procedure should be done always when available?Please clarify! Thanks

Are the design files of this board available from ST website? I'd need to know where can I get 3.3V and tie it to pin1 (Target VCC) off CN14. Then I'll be able to power the target MCU through this connector.
