Hopefully someone can give me a hint on what I am doing wrong.I am logging sensor data with the STEVAL-PROTEUS1 board to the PC using the fp-sns-datapro1 project and the cli_example method. When I try to convert the binary .dat to .csv of the ISM330DHCX by using the HS-DL_NanoEdge_Conversion.bat the hsdatalog_to_nanoedge.py script rises and exception at line  102HSDatalogApp.st_hsdatalog.HSD.HSDatalog_v1 - ERROR - Memory Error occoured! You should batch process your ...It also crashes when converting IIS3DWB .dat, but data logged from IIS2DLPC and SST22H sensors are converted correctly.I have also tried to convert the example samples provided in directory STM32CubeFunctionPack_DATAPRO1_v1.1.0\Utilities\SwUtilities\HS_Datalog\PROTEUS_batch_file_examples\AcquisitionExample and the same behaviour occurs.I am using python 3.8 and fp-sns-datapro1 version 1.1.dat collected by bluetooth via STSBLESens App or by USB in MSD mode have also the same problem.Best regards

I executed "Clock Example" on stm32H747I DISCO. I found that after two minutes of execution, the analog clock was about 15 seconds slower. After 53 minutes of execution, it was about 5 minutes slower, and it will become slower and slower. I did not add any The program code is in the M7 core. The way I compare is to enable RTC and uart in the M4 core, use the HAL_RTC_GetTime() function to read out the rtc time every second, and print it out through the uart. My question is, If the analog clock really slows down, is there any way I can correct it without users noticing?

Hello, I stareted to develop PSI5 interface with L9663. My point is to read initialization data via SPI. If I set DOUT1 as direct data output (CH1_CR1->DOUT1_SE = 0), I am able to measure received data on this pin. But if  I set this pin as interrupt (CH1_CR1->DOUT1_SE = 1), then I am not able to read initialization data via SPI (but interrupt is active).  My procedure: 1. set READ_INIT_DATA1 bit in CH1_CR1 2. Enable PSI5 (with requierd settings) 3. Reading initialization data by this command: After this  INITDATA_RDY in SR3 is not set. Is this procedure correct? What I should write to "init_buf_id" and "Register" bits? I tried to make loop for all possible combinations, but there wasn't any data.   Thank you for your response.

Hello friends!Im devloping GUI using TouchGFX on waveshare OpenH7XXI-C board. When im flashing the code. GUI image is getting splitted  from middel.Touchgfx GUI:LCD output

I use ST25R95 to detect the ST25D tag. I keep the tag on the antenna of the Reader all the time, and some situations have occurred. Hi Even if I place it precisely on it all the time, the tag may not be read probabilistically during detection. Is this normal? The antenna fails to read the tag about two or three times out of ten readings. Please help me,thanks~  

This is what I see when writing a new message in the community (or creating a new post). Notice the </> option to insert code snippet.   However, en clicking on the `...` option to expand it, the </> is gone, and I can not find a way to collapse the options to what it was before.   It would be nice to have this fixed. Many thanks.

I want to receive data from my host PC through USB. I'm using the STM32C0 series nucleo board as USB HID device. I have assigned the value of capslock to the user button. and when the button is pressed i want to turn on the user led on the board. the problem is that when i press the user key on stm32 it glows the led but when i press the capslock key on another hid keyboard attaced to my pc then the output is not reflected on the stm32 board. that means it is not receiveing data from host properly . if it's not receiving data properly then why it is turned on by user button . my endpoint settings are as follows.  /* USER CODE BEGIN USB_Device_Init_PreTreatment_1 */HAL_PCDEx_PMAConfig(&hpcd_USB_DRD_FS, 0x00, PCD_SNG_BUF, 0x0C);HAL_PCDEx_PMAConfig(&hpcd_USB_DRD_FS, 0x80, PCD_SNG_BUF, 0x4C);HAL_PCDEx_PMAConfig(&hpcd_USB_DRD_FS, 0x81, PCD_SNG_BUF, 0x8C); // EP1 INHAL_PCDEx_PMAConfig(&hpcd_USB_DRD_FS, 0x02, PCD_SNG_BUF, 0xCC); // EP1 OUT/* USER CODE END USB_Device_

There is a bug in the new cube ide version in the lwip vonfiguration for the STM32F7 LWIP_RAM_HEAP_POINTER (RAM Heap Pointer) 0x30004000There is no such RAM location in the STM32F7. the correct value should be zero but better u guys check it. by the way this option was not there for the F7 LWIP Key options settings in the previous cube ide version. 

HiMy board is STM32F407G so I want to understand the tx mailbox callback once interrupt hit I am sharing project in which I am sending CAN1 to CAN2 and CAN2 to CAN1 in loop back mode same ID.So rxindication is working fine and this is the project I got from one of your technical executive  ,so how will "hcan->TxMailbox0CompleteCallback(hcan);" get called because in above line we are clearing "/* Clear the Transmission Complete flag (and TXOK0,ALST0,TERR0 bits) */__HAL_CAN_CLEAR_FLAG(hcan, CAN_FLAG_RQCP0);"which also clears "if ((tsrflags & CAN_TSR_TXOK0) != 0U)" TXOK0 bit also so if condition will not satisfy . please guide me  /* Transmit Mailbox empty interrupt management *****************************/ if ((interrupts & CAN_IT_TX_MAILBOX_EMPTY) != 0U) { /* Transmit Mailbox 0 management *****************************************/ if ((tsrflags & CAN_TSR_RQCP0) != 0U) { /* Clear the Transmission Complete flag (and TXOK0,ALST0,TERR0 bits) */ __HAL_CAN

Hello,On the board NUCLEO-L433RC-P I can see the copper shape(see the copper in the white ellipse). Is the lines  connected? What's the function? Thanks!  

Is there a recommended RAM address for placing the framebuffer on the STM32H563?  I just picked out 0x20040000 but wondered if I should just put it at the beginning address (0x20000000), wasn't sure what is recommended.

I am trying to use the standby mode. As the datasheet specifies, it can only wake up from this mode from the reset pin, wake-up pin, or RTC trigger. I searched on the internet to find out how to do it.If I use standby mode like this in the main it works correctly (so without the sequencer):   while (1) { /* USER CODE END WHILE */ //MX_APPE_Process(); /* USER CODE BEGIN 3 */ for (int i = 0; i<5;i++) { HAL_GPIO_TogglePin(LD3_GPIO_Port, LD3_Pin); HAL_Delay(50); } HAL_PWR_DisableWakeUpPin(PWR_WAKEUP_PIN4); HAL_PWR_EnableWakeUpPin(PWR_WAKEUP_PIN4_LOW); /* Clear the WU FLAG */ __HAL_PWR_CLEAR_FLAG(PWR_FLAG_WU); HAL_PWR_EnterSTANDBYMode(); }  But I use Bluetooth and I have to use the sequencer. And I have a function like this:void task_foo() { HAL_GPIO_TogglePin(LD3_GPIO_Port, LD3_Pin); count++; if (count > 5) { count = 0; HAL_PWR_DisableWakeUpPin(PWR_WAKEUP_PIN4); /* Enable WakeUp Pin PWR_WAKEUP_PIN4 connected to PA2 */

I need to connet usb camera to stm32h743. But I can't find UVC(USB VEDIO CLASS) in STM32Cube_FW_H7_V1.11.x\Middlewares\ST\STM32_USB_Host_Library\Class. There is no UVC in cubemx too. Any idea to achieve ti?

Is there a recommended minimum SMT package size and power rating for resistor R4 (8R2) please?

Hi,I'm encountering an issue with my STM32H750 MCU. I download my program to the flash via the UART interface using STM32CubeProgrammer. The MCU can work well for a few days, but suddenly crashed.

Hi there,I have an ST-Link V2 which i want to use for programming a .bin file to an stm32G0 MCU. Afterwards i want to set the RTC register to the time beeing. It already works "manually" but i wanted to write a script to automate the process.I already managed to script an automated RTC register setup, but the script needs the ST-Link to run with the libusb driver.Now i wanted to automate the .bin file programming with the CubeProgrammer CLI, but i can't connect to the St-link when using the libusb driver. To make things more confusing, i can still connect with the CubeProgrammer GUI when setting the option shared to enabled. After some reading of the docs i also managed to get the probe listed on the CLI when using   -l stlink-shared  It gives the following output:   ------------------------------------------------------------------- STM32CubeProgrammer v2.18.0 ------------------------------------------------------------------- ===== STLi

I've been using for a bit a SPC58 eval-board and i was wondering how to share global variables between the two cores. I searched around on the internet finding nothing useful. Is "volatile int" enough even for a rough and dirty data sharing or should I use something like SRAM and its shared memory location?

Hello,I've designed my own PCB using the STM32H533CET6 microcontroller. However, when I try to connect to it using an ST-Link V2 via SWD, STM32Cube Programmer gives me the error: "Cannot identify the device".I've already tried connecting under reset and adjusting the connection settings, but nothing seems to work. Additionally, on another PCB that was previously working well, I replaced the STM32F303 with the STM32H533, and the same issue occurred.Could you please help me with this? I'm completely at a loss as to what might be causing the error.Thank you!    

 I cannot get scrollWheelUpdateItem callback to fire when the scrollWheel is moved. void Button1MenuView::scrollWheelUpdateItem(MenuElement& item, int16_t itemIndex) { // Override and implement this function in Button1Menu item.setNumber(itemIndex); } scrollWheelUpdateItem only gets called once in Button1MenuView.cpp prior to setupScreen:  void Button1MenuView::setupScreen() { Button1MenuViewBase::setupScreen(); for (int i = 0; i < scrollWheelListItems.getNumberOfDrawables(); i++) { scrollWheel.itemChanged(i); scrollWheelListItems[i].updateText(i); } } I assume it should get called whenever the scroll wheel is touched? Or do I need to set up a different callback? My Container for scrollWheel is MenuElement.cpp:  #include <gui/containers/MenuElement.hpp> #include <texts/TextKeysAndLanguages.hpp> MenuElement::MenuElement() { } void MenuElement::initialize() { MenuElementBase::initialize(); } void MenuElement

I'm using a STM32L151RBT6 and trying to debug with a STLink V3.The debugger loses connection when I encounter the line:PWR_VoltageScalingConfig(PWR_VoltageScaling_Range3); Specifically, when it changes the PWR-CR Bits 12:11 (VOS).

When in the description of features of a Nucleo board, it says:Cryptography: NUCLEO-H533RE, NUCLEO-U083RC, and NUCLEO-U545RE-QAs in the case of the NUCLEO-C031C6 in its description.

 I am studying a project that requires a very small microcontroller. It will only drive analog and digital ports, but we need the I2C protocol and maybe even CAN. I was advised to use the STM8, but I am not comfortable with this choice. And I wanted to adopt something that was Cortex-M0.What would be better? The STM8 or an STM32F0 or even another Cortex-M+. What is the future of the STM8 family?Would it be advisable to mix architectures in a new project? 

I am willing to drive a 0.1OHM resistive lead with 4A.Can It be done? eDesignSuite notes that it is possible.I am getting only ~1.4 Amps in my setup

Hi ST team, Today I have an issue in my hardware.I flash a software via STLink in debug mode succesfully. When I start the program, the console shows that "cannot read register..." or something like that :( I cannot remember.After that, STLink cannot find the target board so that I cannot reflash or do anything with my hardware. I tried the same steps in other hardware and the same issue happened so I think this is not hardware issue.  Please help me check this issue. I also attached Debug folder. Could you please help me try to see if issue also happens in your hardware? Thank you very much. 

I have a 12V GPIO high logic input on my board. Should I convert it to a 5V logic level or a 3.3V logic level? Previously, I have implemented 12V to 5V logic level conversion and already have components for this conversion in my inventory. If feasible, can I proceed with 12V to 5V conversion, or is it generally more advantageous to convert 12V high to 3.3V logic level for better compatibility or performance? Is there any recommended project/schematic/component that I should look into for this application?
