Hello, I am working on a project that integrates the ST25DV64KC NFC chip and I think that there is a bug in ST25DVxxKC_ReadMemSize function. I added the driver from the STM32CubeMX X-CUBE-NFC7 pack. I also found a GitHub repository with this pack but it is empty. How can I report a bug?The mentioned function should compute the size of the EEPROM memory but the condition on line 1252 fails, so the size is not computed and the NFCTAG_OK is returned. When the inequality operator is inverted the function works as expected.Can you point me to the bug tracker or the correct repository?Thanks.Best regards,Tomas

I have a TouchGFX project with some buttons used for navigating a menu. The problem is that for some reason every couple of touches is registered as a double click. So I click the touch button once, but the virtual function called by the click event is called twice. Any way to decrease the sensitivity?I can do this in the source code, but wondering if there is a way directly in TouchGFX designer.

Hello,I am currently testing my custom board that utilizes the STM32H7B3IIT6 MCU. Since it is a custom board, I generated the code via CubeMX with the TouchGFX 4.20.0 software package. When I try to run the firmware, I noticed that I never entered the model::tick() function in the Model.cpp function. I ran the debugger and, in the taskEntry code, I have a function OSWrappers::waitForVSync() and the firmware stays in that function. It never gets past there. This function exists in my "custom board" bring up where I used the STM32H7B3I-EVAL evaluation board and it does not get stuck in it. I acknowledge that TouchGFX know the evaluation board's pinout and specific configuration. My custom board cannot use that, so I copied the files from the evaluation board's working code and pasted them into my custom board project. I have attached my .ioc file for reference, along with the snippet of my taskEntry code.void TouchGFXHAL::taskEntry() { enableLCDControllerInterrupt(); enableInterrupts()

In my organization we have developed a few docker images so that any developer is able to quickly get a working development environment having all the needed tools (e.g. compiler, debugger, static analysis tools, utilities, programmers, etc.)A very useful tool to have is the Cube Programmer, especially the cli version, to have the official application to program microcontrollers.However at the moment it is not easy to include it inside a dockerfile, because I could find no permanent link for download, and manual operations are required to download it and install it, defeating the purpose of a ready to go environment which is what we want to obtain.At the moment we've been using other programmers (e.g. pyocd or texane/st-link) but for some specific things (e.g. unlocking, option bytes) the cube programmer is more reliable and would be nice to have.So my question is, is there a way to have a permanent link for downloading the cube programmer, so that it can be easily downloaded and insta

Hello everyone,I'm working on a STM32L4 project which embeds a QSPI external Flash Memory (not yet sourced but doesn't matter).This QSPI Flash Memory would be splitted into 2 parts, one for TouchGFX Images and one for 10MB Filesystem. This FS will have some configurations files and above all a 300kB DataLog file updated each second. The aim is that this DataLog would be easily exported to a PC by USB.So this is how the stage is set. The DataLog file will be updated more than 500 000 times per year, so I obviously have to implement a wear leveling algorithm.I've been thinking for LittleFS rathan than FatFS for his wear leveling feature and then use this FS as a USB MSC. Will these files be readable/writable by a PC ?Are my ideas faisible ? If not, would you have some recommendations ?I hope that everythings's clear, Many thanks for being interested to my demand,Maël

Good day, Support TeamWe chose the STM32G484QET6 for our product development, and I have a question about programming in production time that I've listed below.In production, Can we dump the hex file into the controller(STM32G484QET6) via UART or SPI or Modbus?if have any documents regarding this so please provide them to usThanksHiren R.

I have created a project in IAR Embedded Workbench and it is working alright but now due to some reasons I have converted and debugging the same project with same buffer values in STM32cubeide but in this compiler it is showing "region RAM overflowed by 7256 bytes" and also i have modified the .ld file according to the .icf file of IAR embedded workbench.I have attached the both files. Please help me !!!

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

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
