Hi,I can't find any information about the IC shown in the picture attached. It seems to be a very very old part that is no longer in production and ST support do not have records for anymore.Can you help find a datasheet or an equivalent component?Thanks

Hi,When I close GFX Designer its window disappears, however, the TouchGFXDesigner-4.23.1.exe stays running in the backround - for every opened/closed *.touchgfx project. Does anyone experiences this GFX misbehaviour ?Best regardsFerro

Hi all,we have successully used an external SPI memory to store images.We have defined an external Flash section in our linker file ExtFlashSection :{*(ExtFlashSection ExtFlashSection.*)*(.gnu.linkonce.r.*). = ALIGN(0x4);} >SPI_FLASH and then extract the images from elf file with this command:arm-none-eabi-objcopy.exe --dump-section ExtFlashSection=images.bin Test.elfAll works perfectly.Now we want to store the fonts into the external memory. From the TouchGfx guide we see that we have to add the font section into linker file and thats ok.ExtFlashSection :{*(ExtFlashSection ExtFlashSection.*)*(.gnu.linkonce.r.*). = ALIGN(0x4);} >SPI_FLASHFontFlashSection :{*(FontFlashSection FontFlashSection.*)*(.gnu.linkonce.r.*). = ALIGN(0x4);} >SPI_FLASHNow:should we extract two separate bin files (one for the images and one for the fonts)? And in that case should we merge the bin togheter?arm-none-eabi-objcopy.exe --dump-section ExtFlashSection=images.bin Test.elfarm-none-eabi-ob

I tried to integrate a working project for version 4.23.0 to 4.23.2 and get the current error as seen in screenshot.I tried to troubleshoot by generating a default project via TGFX to my stm32h7b3I -EVAL board (with a 480x480 screen and GT911 touch driver), and the exact same code gives no errors..... the only real difference lies in STM32TouchController.cpp where I have used the GT911 driver instead of the ft5336 touch controller and I have changed the coordinates to be uint16_t instead of uint32_t.

I configured the watchdog of ADC using stm32cubemx and found that only watchdog 1 can display channel configuration options. Watchdogs 2 and 3 do not have this option.  When generating code, even though 2 and 3 watchdogs are enabled, the code for these two will not be generated. Do anyone know what the reason is? Thanks so much. (I have read two topics about this problem in the community, but they don't tell me why and how to solve.) 

Some 'L4 RMs suffered/suffer from this, too (lazy to look up).JW

Hello, I was wondering by using X-AI package. Will I be able to use the XGboost model converted to ONXX format in STM32 MP157 A7 core.  Or it only supports Neural Network models? I was browsing through the forum and found that ONXX runtime recipe is required in order to achieve this. Here is the link for that https://community.st.com/t5/stm32-mpus-products/hello-can-i-implement-random-forest-classifier-on-stm32-mpu-if/td-p/160467 However, I see ST wiki has a page showing how to measure performance of models using ONXX runtime. website is here.  Are both the ONXX runtime links same? I prefer using st link since it has detailed description on how to use it. Thanks  

Hi all,Im having problems with my IDE, I cant seem to add the stm32f407xx.h library to my project, which is an internal library provided by ST. I added it to the linker GCC both the path to the file directory and the file itself and its still not accepted by the compiler.  

What is the function of accessing 16 Bit Resisters available on VL6180 Controller?

Hi community,I have a display, which has only CLK, DI and CS pin for SPI communication. It uses TI protocol.The original driver is only working with raspberry pi, I try to import it into my custom STM32 MCU board, the CLK and CS signals seem okay,  Only the MOSI signal is always low. it seems no data is really sent to the display. here is the signal capture from logic analyzer. The whole write sequence: zoom in, single byte write:what could be the reason? Thanks in advance.  

Sorry, my first time programming an STM32.  I have a bunch of data I need to store for a few hours, and the thought was to store it in Flash since there's a lot more of it (512k vs. 128k for regular RAM) but it looks to be pretty daunting. I've been reading a bunch of articles online, and they all seem to contradict each other, and they all say things like "all you do is write to the memory location, just like regular RAM" and then in the fine print it lists the 43 things you have to do first, - turn off IRQs, update control registers, etc., etc., etc.Is there an example program for the STM32G474RE that shows a simple "write a bunch of data to Flash" and an equally simple "read a bunch of data from Flash"?Thanks!Chris 

Hi, is there CAN support available in STM32H573I-DK board, when I check STM32H573I-DK datasheet 2 CAN FD is mentioned. but pin io details are not available in user manual.  

I have a working project that was running in STM32CubeIDE v1.7.0, with STM32CubeMX v6.3.0 and TouchGFX v4.18. After updating to STM32CubeIDE v1.10.1, STM32CubeMX v6.6.1, and TouchGFX v4.20, the program is getting stuck in HAL_Delay when HAL::initialize() is initializing the touchscreen.I watch uwTick variable up until the HAL::initialize() call, and it is updating. It is no longer updating in the Hal_GetTick function during touchscreen initialization.I have not changed any settings in the project or in CubeMX. I am not doing any overrides of the system tick initialization. Any ideas why this is happening?

Hey everyone,(code is attached to the post)I'm currently working on a project and using the NUCLEO-H755ZI-Q development board.A part of this project contains datahandling between the M7 und M4 Core. Therefore I read through a lot of documentation and tried out HSEM (which works great, but needs the CPU to handle, which is not optimal for my usecase) and DMA Handling with using the D3 sRAM Domain.My problem seems to be, that I'm not able to generate an interrupt / callback on the other core (e.g. the M7 core handels data over DMA into the sRAM and a callback on the M7 ist thrown on completion. I'm able to debug as far, that I can see, that both the M7 und M4 can see the data correctly written into the RAM thanks to MPU configuration.)What I need - or more like I think I need - is a way to generate an interrupt or callback on the M4, so I knows to get the new data and work with it. (and yes I future also the other way round from M4 to M7)Maybe there is a better way to handel my problem -

Hi. If the device is received with no ECOPACK on packaging, does it mean it is NOT ROHS-compliant?However, datasheet says it is supposed to be in ECOPACK packages.   Is there any other way to confirm if the device is ROHS or NON-ROHS compliant?  

Hello All,I designed and built a bare metal board with an STM32H723ZGT6 and it runs fine.I have blinking LED's, timer / interrupts running, HSE and LSE etc.I have been trying to figure out why if I toggle the power supply the device will not boot up clean.The device appears stable in that I have left it running overnight withn o issues.I have looked through datasheets etc. but think I am missing something really simple.The device is powered through a 3.6V 500ma LDO voltage regulator and I can see no issues on this. Pointers on where too look would be appreciated.  

Hello everyone, I hope you're doing well.I'm starting a new project where the main requirement is Wi-Fi connectivity and connection to AWS IoT. While researching what ST has to offer in this regard, I came across the document: https://community.st.com/t5/stm32-mcus/getting-started-with-stm32u5-iot-discovery-kit-and-aws/ta-p/49682. It discusses the B-U585I-IOT02A kit, which seems to be quite comprehensive. However, I noticed that the code available in the document https://github.com/FreeRTOS/iot-reference-stm32u5.git entirely uses FreeRTOS and does not include the .ioc file, which I am quite familiar with for configuring pins, timers, etc.Does ST have any other examples or kits that include Wi-Fi and AWS IoT connectivity? If yes, could you please provide a reference link? If not, I would like to know if it's possible to port the pure FreeRTOS code to a version that uses both FreeRTOS and the ST configurator .ioc.Thank you.

Hello,I am trying to port/get running the NFC08A1 RFAL polling demo on the NUCLEO-F072B.  I had no issues using L476RG.  I am fairly certain I have SPI set up correctly in CubeMX.  But, I am getting stuck at initialization, specifically at st25r3916CheckChipID(). ID is read as 0x18, which is causing it to return false and throw an error.  I was taking a look at the SPI traces and MISO (pink) looks not quite as clean as MOSI (blue) (sorry, had to capture using phone camera):Rise/fall on MISO looks a little slow compared to MOSI.  Could this be causing the issue?  From the datasheet, it looks like chip ID should come back as 0x31:Anywhere else you think I should look?  Thanks.

Two devices A & B are communicating on UART. A sends data stream to B. B sends one byte data back to A to acknowldge that data has been received. I want to implement if A doesn't receive acknowledgement from B then it display Error message on LCD.Please suggest best logic in A to implement this.As far I think I should start the UART_Receive_IT API for one byte . and complete callback sets the flag for acknowlegement. Incase flag is not set within one second or so after sending data then A display Error message on LCD. Should I start HAL_Delay(1000) after sending data and then check for flag set or not?If anyother best way, kindly suggest. I am still relatively new to coding word..so trying to find best ways.. ;)

I'm working on implementing STEVAL-ST25R3916B reader expansion board circuit schematic into custom PCB. Can I please get the actual design files for these, including the layout. I did find the pdf version but it would be great to have the design files. If the files are in Orcad format can I please get the .alg for the .brd file?Thank you, BV

I create a project by selecting the NUCLEO-H563ZI and answer yes to the question about initializing peripherals and the project will not build.  The error is: file included from ../Drivers/STM32H5xx_HAL_Driver/Inc/stm32h5xx_hal.h:29,from ../Drivers/STM32H5xx_HAL_Driver/Src/stm32h5xx_hal.c:35:../Core/Inc/stm32h5xx_hal_conf.h:409:11: fatal error: stm32h5xx_hal_usart.h: No such file or directory409 | #include "stm32h5xx_hal_usart.h"| ^~~~~~~~~~~~~~~~~~~~~~~ The IDE reports itself to be STM32CubeIDEVersion: 1.14.0Build: 19471_20231121_1200 (UTC)If I try to read the ioc file and generate code from the STM32CubeMX standalone the problem persists. CubeMX reports itself to be "Version 6.10.0"I see others have reported similar problems, please provide some suggestions on the fix.  

I'm using TouchGFX with an RTOS.How can I shutdown TouchGFX, so that my RTOS is still running? This would require to exit from HAL::taskEntry().

Hello,I am developing a model for human activity recognition on NEAI based on LSM6DSOX module. I managed to deploy a vanilla version using gyroscope data only, and now I'm creating a new project to deal with 6 axis (3 from gyroscope + 3 from accelerometer). However, I am not managing to add the signals to my project, because the import signal functionality identifies a problem in my data acquisition. My input sequence via Serial is in the following shape:acc_x acc_y acc_z rot_x rot_y rot_z, all of them separated by space.NEAI says there's a problem with the data basically in every row, starting from the column 7 (where I start to collect this sequence of 6-axis for a second time). I am not experienced with NEAI, and probably this might be related to the way I'm sending the data, but I can't find the solution.In my vanilla version, my print was in the shape "rot_x rot_y rot_z" and it worked fine. I'm using a buffer of size 64 (per axis).How should I format the data in the serial exactly

I am trying to establsih communication between a NUCLEO G474RE and a NUCLEO H7A3ZI-Q thorugh FDCAN. I have successfully accomplished FDCAN communication for both the boards individually using Normal mode as these boards have multiple FDCAN peripherals. I am using two ADM3050E FDCAN transceivers for communication. Now, I have set the baud rate and clock speed of FDCAN same for both boards, yet I have been unsuccessful. So, I wanted to know what I am doing wrong. Please find atteched zip files containing my projects.

Hi,i was hoping, that the Link-V3 would just work, after i used nucleo boards already. But i was dissapointed. I use the GDB server, and it says:ST-Link enumeration failedError in initializing ST-LINK device.Reason: ST-LINK DLL error.I just checked a Nucleo board, and there is no problem.The installation of the driver worked without errors.
