Hi Team,We have the two boards as mentioned below.                      The Code generated in Cube MX is for the F401RETX(which configures the MCU inside VL53L8CX)In the above diagram , the host is the F401RETX . Please confirm , if our understanding is correct. Regards,Vikaash.K.B

Edit by ST Moderator: This post has been translated from Chinese to comply with the ST Community Terms and Conditions (§10.2). What is the difference between STM32F070F6 and STM32F070F6P6TR? STM32F070F6和STM32F070F6P6TR的区别是什么呢？

On STM32G0 is it faster to disable and enable interrupts using the functions __STATIC_FORCEINLINE void __enable_irq(void) { __ASM volatile ("cpsie i" : : : "memory"); } __STATIC_FORCEINLINE void __disable_irq(void) { __ASM volatile ("cpsid i" : : : "memory"); }I'm not sure what "memory" does in the above. or is the code below faster__STATIC_INLINE void __NVIC_DisableIRQ(IRQn_Type IRQn) { if ((int32_t)(IRQn) >= 0) { NVIC->ICER[0U] = (uint32_t)(1UL << (((uint32_t)IRQn) & 0x1FUL)); __DSB(); __ISB(); } } __STATIC_INLINE void __NVIC_EnableIRQ(IRQn_Type IRQn) { if ((int32_t)(IRQn) >= 0) { __COMPILER_BARRIER(); NVIC->ISER[0U] = (uint32_t)(1UL << (((uint32_t)IRQn) & 0x1FUL)); __COMPILER_BARRIER(); } }I realize using the NVIC is more fine grained but just wondering what the memory behaviors differences are of these two and if one is heavier than the other.Thanks! xxx

Hi,I am currently working with the nucleo-n657x0-q development board and trying to use the ST neural-ART NPU of the STM32N657X0 MCU. While I know that neural network models can be automatically mapped to the NPU through the STEdgeAI-core, I was wondering if there is any documentation on how I could manually program the NPU? Either through a library/API or through low level functions.Thanks in advance!

Hello Everyone, I am currently using the vl53lmz_uld_api  tto process data measured by the VL53L8CX sensor. I have also used the "example_12_cnh_data" to retrieve data from my sensor. However, the incoming data seems completely incorrect, and I don't know where the issue lies. When I hold my sensor 20-25 cm in front of an obstacle, I receive highly unreasonable data: Zone : 40, Status : 0, Distance : 1383 mm Zone : 41, Status : 13, Distance : 1892 mm Zone : 42, Status : 5, Distance : 1371 mm Zone : 43, Status : 5, Distance : 1367 mm Zone : 44, Status : 5, Distance : 1347 mm Zone : 45, Status : 5, Distance : 1370 mm Zone : 46, Status : 5, Distance : 2448 mm Zone : 47, Status : 9, Distance : 2262 mm Zone : 48, Status : 4, Distance : 2977 mm Zone : 49, Status : 0, Distance : 1398 mm Zone : 50, Status : 5, Distance : 1381 mm     Can someone please help me to understand what i am doing wrong  here is my main.c:  int main(void) { /* USER CODE BEGIN 1 */

Hello,I am listing files on the SD card using fileX. My issue that some of the files contain Czech Characters (eg. č,ž,ě,š and few more). It seems that files with czech characters are read with shortened file names. (FX_MAX_LONG_NAME_LEN is set to 256). For example file "113---Kočka ze Záběhlic.dat" is read as "113---~1.DAT". File with almost the same name length "112---Dejte mu zahrát.dat" is read correctly.So my theory is it has something to do with the character encoding.I used to read all the names correctly with fatfs in the past however this is first time I am using FileX.Any tips?regards Jeronym  

HiI got a new STM32F407VGT6 Dicovery board which is quite awesome. I have been playing with it and now I want to print stuff to a terminal via Serial. I looked up some tutotials and there they simply use the on board STLink becasue USART pins are connected between the MCU and the STLINK and gets the Serial data through USB to the computer. To do that they install VCP drivers which I also did. But when I plug in my STM32 board it does not show as an COM Port. Instead it shows as STM32 STLink.This is the tutorial I have been following. For now I am using an external Serial Converter and getting the job done. But it is messy and I would like to know how to get this done with the STLink itseld. Please share your thoughts with me.Best Regards

Earlier I implemented file transfer using TFTP in which my stm32 module was working as a server. But now I want to make it work as a TFTP client. Is there any example regarding TFTP client.

Hi everybody,I am currently working on an STM32F446REDatasheet I need to save some bytes like 10 for example. I need to save some bytes like 10 for example, in flash memory to save my HMI configuration.I have read articles and done research but I don't understand everything.The memory is divided into sectors. I think I have to write my data to the end of the memory. However, the last sector is 128kB. Do I have to erase 128kB each time? Isn't there a simpler and less resource-intensive method? Can't we just delete a 2KB page?I really need to save only a few variables Thank you to reading me   

Hello  everyone,  I started learning programming on the STM32 ecosystem a few weeks ago, and I'm currently trying to get data from the VL53L8CX sensor using the NUCLEO-F401RE expansion boards and the vl53l8cx_api. I wrote a small program based on what I have seen in other projects, but my code doesn't work at all. While debugging, I discovered that the program jumps to the HardFault_Handler() function at this line in vl53l8cx_init().   status |= VL53L8CX_WrByte(&(p_dev->platform), 0x7fff, 0x00); Here is the essential part of my code maybe someone have any solution: #include "vl53l8cx_api.h" #include "main.h" #include "stm32f4xx_hal.h" #include <stdio.h> // Private variables --------------------------------------------------------- static VL53L8CX_Configuration tof_dev; // Sensor-Konfiguration static VL53L8CX_ResultsData results; // Ergebnis der Messung static int32_t status ; // Status für Fehlerbehandlung static void MX_VL53L8CX_SimpleRanging_Process(voi

Hello, I am using a STM32G0B1xx MCU with the X-CUBE-TCPP v4.1.0 stack an FreeRTOS. I am trying to setup a USB-c port with OTG-functionality. I am having some problems understanding your X-CUBE-TCPP-stack.Some background info:I am initializing the software with MX_UCPD1_Init() and MX_USBPD_Init() provided by the original stack/CubeMX. I am testing the connection with several USB-devices an -hosts.  We tested a previous version of our software on a  NUCLEO-G071RB in combination with a X-NUCLEO-DRP1M1 with your Tool "STM32CubeMonitor-UCPD", which was working fine. 1. The DPM_Params[0].PE_DataRole is always defined as USBPD_PORTDATAROLE_UFP, no matter what i connect to the USB-c port. Is this intended? 2. I do not get a Notification for USBPD_NOTIFY_DATAROLESWAP_UFP or for USBPD_NOTIFY_DATAROLESWAP_DFP in here, no matter what I connect to the USB-c port:/** * @brief Callback function called by PE to inform DPM about PE event. * @PAra

Hello!I wonder if anyone has had experience making a dimmer on an STM32F746? For example, want the display to dim after 1 minute of being idle. It should remain bright enough to read, then return to full brightness on touch.I saw some posts that PWM should be used with a Timer pin, but this doesn't appear to be an option on the STM32F746?Thanks,the Windmill

Hello,I created a timer for a display using two text areas. One is a text area with a single wildcard (i.e. minutes), and another is a text area with two wildcards (i.e. seconds). It runs fine for ~9 minutes and 4 seconds but then suddenly the text area with two wildcard randomly generates a ? on the second wildcard, and this occurs on both the simulation and on the hardware that I am running. The typography has the 0-9 wildcard ranges, for all font sizes used. There are rare occasions when the question mark (?) goes away, but I do not know at what time that occurs. Any help is greatly appreciated.Here is the code that controls the timer.HPP code#ifndef RACETIMERVIEW_HPP #define RACETIMERVIEW_HPP #include <gui_generated/racetimer_screen/RaceTimerViewBase.hpp> #include <gui/racetimer_screen/RaceTimerPresenter.hpp> #include <touchgfx/canvas_widget_renderer/CanvasWidgetRenderer.hpp> #include <touchgfx/Color.hpp> class RaceTimerView : public RaceTimerViewBase { pu

Respected Members,We are using STM32Cube Package 1.16.0 and STM32CubeIDE v1.12.1. We have 10,000 devices in market with BLE stack v1.16.0 and FUS v1.2.0 (STM32WB5MMG). We encountered a BLE related disconnection bug that was resolved when we switch to BLE stack v1.21.0 so now the idea is to wirelessly OTA BLE stack of CM0+ and firmware binary of CM4+.But the problem is that whenever I make a call to FUS using SHCI_C2_FUS_GetState(NULL), it is blocked and keeps waiting on shci_send( SHCI_OPCODE_C2_FUS_GET_STATE, 0, 0, p_rsp ); This call never returns if I check with debugger (STLINK-V3 using IDE attached).Now, if I manually start FUS from CubeProgrammer, then re-run the firmware, FUS get state works but I cannot do this on working devices deployed in the field. If BLE stack is running, I cannot seem to get this call SHCI_C2_FUS_GetState(NULL) to work.The startup script and linker script is attached as well along with .ioc file used to generate project (wb_1.21.0.zip).

Hi everyone, after I've configured TouchGFX, the program needs to be manually run in Keil's debug environment to execute. Why is that?My ICNA3306_DrawBlock data transfer did not use DMA.  

Hi,what is the best way (excluding asking them to use TouchGFX) to show a preview of a touchGFX project - with just button functionality to navigate between screens - to a someone?Is there perhaps a viewer for Window or can a project be compiled and sent as .EXE?If not, what is the best way to send someone an interactive TouchGFX UI project (again, all I need is the navigation between screens through the buttons in the UI)?Thank you

Just a question: I'm using the following code snippet: void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { if (htim == mod_timer){ pwm_timer->Instance->CCR4 = sinetab[loop_cnt++]*global_adc1/4096.; //setzt neuen PWM-Wert aus Tabelle if(loop_cnt == MAX_SAMPLES){ loop_cnt=0; HAL_ADC_Start_IT(&hadc1); HAL_GPIO_WritePin(LED_GPIO_Port,LED_Pin, SET); } } } void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef *hadc) { global_adc1= HAL_ADC_GetValue(hadc); HAL_GPIO_WritePin(LED_GPIO_Port,LED_Pin,RESET); }  Do I have to care about  HAL_ADCEx_Calibration_Start(&hadc1 );If yes, I assume I would do that once in program start in main()? And how do I wait for calibration completion?

Hi all,I'm working with an STM32-based motor control setup ( The EVSPIN32F0251S1 board is a 3-phase complete inverter based on the STSPIN32F0251 controller), and I have a physical PMSM motor that I want to use with FOC (Field Oriented Control).I need help figuring out the following motor parameters:Parameters I want to find:Stator resistance (Rs in Ohms) Stator inductance (Ls in mH) Back-EMF constant (in Vrms/kRPM or Vpeak/kRPM)Maximum mechanical RPM What I have: Physical motor only and basic data (no datasheet)PMSM motor Volt -24Current -4.3 ampPower -105WRPM - 500 Hz- 83.3 HzPole Pair -10Torque -2.0 NmCan measure with multimeter, oscilloscope, etc.Using STM32 Nucleo-F446RE board Planning to use STM32 Motor Control Workbench & SDKMy questions: What is the best method to measure Rs and Ls accurately with basic lab equipment?How can I measure or estimate the BEMF constant?Is there a reliable way to determine the maximum safe RPM if the motor model is unknown?Can the STM32 MC Workben

OK, this is perhaps a fairly stupid question but I do not get it.I have an analogue voltage in range -5V..+5V and wantto measure it with the ADC of an STM32F446. The ADC-input works in range 0..3.3V.I have the feeling I can do that with a simple, resistor-based voltage divider that pulls down the 10V effective of the input value to the 3.3V the ADC expects.But...how has ti voltage divider to look like when going with +-5V, means when it starts at -5V?

Hello@STTwo-32 @Remi QUINTIN , We are using STM32WB55RG MCU for our development. From the examples I came to know that the BLE device  initially starts advertising as peripheral and the mobile device as central will be able to scan the device and initiate the connection. Once connected the device advertising is stopped. But, I came through the BLE stack document and find out it is possible to have simultaneous connections with the BLE peripheral device upto 8. I have been trying to have multiple connections of the BLE, like I want the device to be connected as well as advertiser so that it is possible to connect to with other central devices.Do we have any examples in the STM32WB SDK which shows this behavior of connecting with multiple devices?If yes, please let me know. I have tried my side, changing few lines of code in the software as shown belowFirstly, In app_conf.h, i changed maximum number of simultaneous connections that the device will support to

Good morning everyone,We bought a STM32F103C8T6 Evaluation Board ADS1256 (https://www.amazon.it/Lodokdre-STM32F103C8T6-acquisition-Industrial-Control/dp/B0C582B33D), after writing the firmware I am trying to debug it with the ST-LINK V2 programmer (https://www.digikey.it/it/products/detail/adafruit-industries-llc/2548/6827110). When loading the STM32CUBE IDE firmware I get the error:Error in final launch sequence:Failed to start GDB serverFailed to start GDB serverError in initializing ST-LINK device.Reason: (18) Could not verify ST device! Abort connection.Reading some forums they advise me to use OpenOCD as a debugger, but even with this setting I can't communicate.STM32CubeProggrammer allows me to communicate with the board, but at this stage of work I need the debugger.Can someone kindly give me some advice?Thank you very muchGian

Hello Everyone,I am currently working on a project to determine if it is possible to differentiate between a glass cup and other types of cups using VL53L8CX sensor data histograms, and also to detect the fill level. I have already collected data from the sensor using Example 12 provided in the Ultra Lite Driver, and I have written a small Python script to visualize my data.My first challenge is switching between the 4x4 histogram data format and the 8x8 format. The second challenge is interpreting the incoming bins_data to understand the differences between, for example, a ceramic cup (which is already possible using just the distance data) and an empty glass cup (using the histogram data to make a distinction, detect the edge, and determine the fill level).  Here below is my code stmIDE  Code//__________MY CODE ___________ p_dev.platform.address = 0x52; Reset_Sensor(); if (status != VL53LMZ_STATUS_OK){ printf("vl53lmz_init failed : %d\n"); return status; }

Hi,I think I have found a bug in CubeMX v6.12.0.I have an STM32U595 with USB OTG HS.My USB peripheral is set to use the HSE as it's clock (not PLL1):However, when I try to set the oscillator source for PLL1 to the HSI, CubeMX gives an error declaring that "Only HSE is possible when OTG_HS is using PLL1", which would be try, except OTG_HS is configured to use HSE, not PLL1:Can you either confirm this is fixed in a later version of CubeMX, or otherwise fix it!  

hi,Previously i was using STM32L010K8TX which has 8K memory. I did OTA update in this device via Uart with help of external controller which receive hex file from User. Currently am using STM32L010R8Tx which has 64K memory. And i tried the same OTA program to update the application in this new device but after OTA update the user application is running proper.The external device which receive hex file has a debug communication port to monitor STM32L0 device by communicating in UART. After updating the application the UART communication not at all responding to external device.After completing the OTA update am using GO command to run application (0x08000000) and making Boot Pin Low ( which is making HIGH When Entering to OTA mode). Am using same OTA file commands flow to update which was used for previous device (stm32L010K8Tx) including the memory locations.  but in new device after updating the OTA it stops working Uart peripheral. I am not sure about other peripherals
