As far as i could find it should show up as a mouse and I should only have to edit the report descriptor in usbd_custom_hid_if.c.

I'm trying to receive data from the LPUART1 serial port on the L031K6 development board.Unfortunately all my aproaches failed so far.Sending data works fine in all three modes:BlockingNon-Blocking ITNon-Blocking DMAI'm routing the LPUART1 to PA2 and PA3, which are initially the RX and TX lines of USART2.The USART2 is already in use.Are there any restrictions in using the RX line on PA3 or in using the LPUART1 in receiving data?

what would you like to know？I have downloaded 'en.x-cube-nfc7' according to the instructions，but the ST25 tap app of my phone did not read the "www.st.com/st25-demo" link. What should I do？

Hi,Im using the Embedded Lib.Im experimenting with the demo_ap2p_prop. I want to send a Hex Array as message instead of a string array. Do i use the same funktion?Is there a diffrent with the size ?or is there a other way to send Hex Data ?err = demoTransceiveBlocking( message, strlen(message), &rxData, &rxLen, RFAL_FWT_NONE);i tried sizeof :err = demoTransceiveBlocking( message, size of(message), &rxData, &rxLen, RFAL_FWT_NONE);but the demoTransceiveBlocking funktion gave me back the errorcode 24 "ERR_NOTSUPP" what am i missing?

Hi Everyone.I have tried test NFC use Nucleo-L152RE and X-Nucleo-NFC06A1.I use STM32duino X-NUCLEO-NFC06A1 example to test. It run normally with SPI interface.But when I change it to I2C interface, it can't run.Hardware modification: • solder ST2 and ST4 jumpers • solder R116 and R117 pull-up resistors • remove the SPI solder bridge (R205) • put the I²C solder bridge (R204)Firmware modification: use #define I2C_ENABLED Besides that, I have tried to test I2C scanner, to read the I2C address of NFC06A1, but it can't find I2C device.What should I do in the next step to make it can run with I2C interface?Thanks,

Hello, After creating a project on the SSD in the computer, I have no problems compiling this project. But I cannot compile the project (over TCP/IP) that I created in the server in the company. I keep getting the error "No such file or directory" when I try to compile. What is the reason of this?(Example file path where I am trying to build and compile the project: \\10.0.0.4\bnz-fs\AKN02\AKN02-1A\BNZ02-1B-304\ELECTRONICS\SOFTWARE\MyExamplePROJECT )

Hi,Scaling down an histogram graph to display only one bar triggers a "(min != max)" error.I need to display from 1 to 16 bars on my histogram.I use the setGraphRangeX(int min, int max) function for this.However, when I get down to 1 bar with setGraphRangeX(0, 0) I get an error during execution.This error is clear enough, but I think this limitation should not be there.Is there anyway to get around it?Thanks,Franck.Setup:TouchGFX 4.21.1Error reproduced using TouchGFX simulator and VS2022

Hello, in the application-note(AN5851) of the VL53L4CD ToF Sensor there was a graphical tool used during the experamnet under the name "STSW-IMG039_L4CD", when i search for it now, i can't find it on ST-Website. Is there any replacment for this tool(or can be downloaded from any source)?Thank you

The new STM32C0 series comes to complete the STM32 Mainstream MCUs portfolio.The STM32C0 series is the most cost-effective STM32 MCU. It bridges the gap between 8- or 16-bit MCUs and higher performance 32-bit MCUs. Built on the same technological platform as the STM32G0, the STM32C0 ensures you reduce costs without impacting design quality and reliability. The STM32C0 series offers up to 32 Kbytes of flash memory and 6 to 12 Kbytes of RAM. It comes in a variety of 8- to 48-pin packages (UFQFPN20 available), down to 1.70 x 1.42 mm (tiniest package over all STM32 products with WLSCP12). You can find more details about this product in Your next 8-bit MCU is a 32-bit. It’s called STM32C0! - STMicroelectronics.If you have any question or feedback about this product, you can share it with Community. Just pay attention to add relevant topic STM32C0.

HiI have a STM32F756VGT6.Please see picture attached.There are two dots and the datasheet sheds no light on which could be pin-1Could someone please clarify this silly question.RegardsSrinath

Hi,I want to extend SDRAM by FMC at stm32h743iit6. When configuring the MPU, there was some error as below, what are the wrong parameters? 

I am sending a string "Chicken" word on UART Transmit and I want to check if I can receive the full string in the UART receive. To do that, I have physically connected the TX and RX pin together via a wire.I am able to check that Transmit is working properly via Hterm (I can see the full string) and also on oscilloscope. But for Receive, I am seeing only the 1st character which is 'C', the rest does not appear.Can someone help with that? I can't figure out why.../* USER CODE BEGIN Header */ /** ****************************************************************************** * USART 1 Bridging test: Using a wire to create physical bridge between TX & RX * of Arduino connector D0 & D1 to verify that char received is the same as char sent ****************************************************************************** * Problem: * 1.

A very strange things happened when trying to browse (open a project) on most of the directories located on my MAC (OS Monterey on Apple M1 MAX):I cannot see the folders structure when accessing DocumentsI can see folders when accessing PicturesThe directories informations looks identical (see the pictures)Can you please explain what is the reason? I use the latest STM32CubeMX.Thanks,Andrei

We are using the STM32G0B1CC and have noticed that if we call HAL_ADCEx_Calibration_Start() too soon after calling HAL_ADC_Init() that the CALFACT register comes back as 0. If we insert a substantial delay, say 20 ms between the 2 calls, CALFACT is populated with a reasonable value, and later conversions are considerably more accurate. HAL_ADCEx_Calibration_Start() in all cases returns HAL_OK. I'm trying to understand why the need for the delay:void MX_ADC1_Init(void){ ADC_ChannelConfTypeDef sConfig = {0}; hadc1.Instance = ADC1; hadc1.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV4; hadc1.Init.Resolution = ADC_RESOLUTION_12B; hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc1.Init.ScanConvMode = ADC_SCAN_SEQ_FIXED; hadc1.Init.EOCSelection = ADC_EOC_SINGLE_CONV; hadc1.Init.LowPowerAutoWait = DISABLE; hadc1.Init.LowPowerAutoPowerOff = DISABLE; hadc1.Init.ContinuousConvMode = DISABLE; hadc1.Init.NbrOfConversion = 1; hadc1.Init.Disc

I'm working with the "NUCLEO-U575ZI-Q" development board and I compile using STM32CubeIDE 1.6.1. My project uses FreeRTOS and if I debug my project and halt execution, then I can see the currently executing thread's stack trace in the upper left part of STM32CubeIDE and the current line of code of execution is highlighted. Is there a way to someone (not necessarily inside STM32CubeIDE) show the stack traces of all threads? And, as a bonus, is it possible to show/highlight the lines of code that each thread last executed on?

I need a small form factor RF ID Reader (max space available for reader antenna is 60mm x 40 mm) and max tag size is 55mm x 13 mm. Can someone help me to find out the best possible RF ID reader and Tag solution (LF/HF/UHF)? Any design consultant?

Hi,I am using STM32CubeProgrammer version 2.12 running on Windows 10 to connect to the STM32MP157F-DK2 board ST-LINK connector CN-11.I managed to connect and when I click "Firmware upgrade" the STLinkUpgrade 3.4.0 window opens.However, when I press "Open in update mode" I get the error message:Error connecting to device ST-LINK/V2-1 (error 0x3); check USB connection and refresh the device listAt this point the connection is dropped and I have to connect again.I also noticed that the "Current Firmware" was not listed as I expected from my experience of upgrading the ST-LINK firmware on other NUCLEO and DISCOVERY boards.Maybe the current version of STM32CubeProgrammer doesn't yet support the STM32MP157F-DK2 board ?Any help would be much appreciated.Kind regards,Steinar

Why am I unable to read NDEF information in the STSW-ST25001 APP using the following code, with no messages being displayed?

Hello,I am try to control an external DAC system with the SPI interface. The clock signal shape looks like the attached file. I didn't figure out the meaning of the signal. Yellow is the clock signal and the blue is CS signal.

What is the recommended footprint for this device?The TN1171 technical note is next to useless, so please don't direct me there.What is the width of this pad please, as I cannot decipher your data sheet for this information  Frankly, I'm a little disappointed this information is so confusing and hard to extrapolate.
