请问有人能提供一下STM32G030xx或者STM32其他系列MCU作为IIC从机进行通信的例程吗，谢谢。

Moved from this thread. Hello @mƎALLEm  I'm facing this issue on CubeMX 6.14.1. Project for STM32MP157FACx (STM32MP1 series package) v 1.7.0.  

Hi All,we are currently working with both the VL53L5CX and L7CX ToF-Sensors.In EMC testing, there are sometimes occurences of the statuses TIMEOUT_ERROR and CORRUPTED_FRAME during the acquisitons (via the Vl53lxcx_get_ranging_data uld function).If these statuses occur, the only thing that gets the sensor back to measuring correctly seems to be a full power-on reset. Otherwise, all uld functions like get_ranging_data or get/set anything keep returning the same error code. Just resetting the i2c by toggling I2C_RST does not seem to do the trick.My question is now: is there another way to recover from these error state of the sensor? Especially one that does not require downloading the sensor firmware again?Thanks in Advance!    

I am setting up a project using CubeMX to evaluate the 67W61M1 device, using a Nucleo-F411RE. As far as I can tell the X-NUCLEO-67W61M1 needs SPI1 of the Nucleo for communication. Unfortunately, the Nucleo has SWO (PB3) where SPI1_SCK and while I see a solder bridge that can remove SWO from the STLink-OB, I do not see a way of disabling the SWO connection to PB3.I tried resetting the state of PB3 in Cube MX and then I can enable SPI, however the "SYS" module then issues a warning about a conflict with SPI1 full duplex master.Is this the correct way to configure SPI1 and Serial Debug?Sid

Hi, I'm using the STM32H7 family and have spent several days trying to get dual mode working correctly with the STM32H723.  I finally switched to the STM32H753 so I could try the ADC_DualModeInterleaved example from the repository at STM32CubeH7/Projects/NUCLEO-H743ZI/Examples/ADC/ADC_DualModeInterleaved at master · STMicroelectronics/STM32CubeH7 · GitHub.  It seems to work, but I need regular simultaneous mode instead.In the code, I replaced the MultiModeInit.Mode =ADC_DUALMODE_INTERL statement with  MultiModeInit.Mode = ADC_DUALMODE_REGSIMULT, and also reconfigured the ADC channels as follows: //Original #define ADCx_CHANNELa ADC_CHANNEL_18#define ADCx_CHANNELa ADC_CHANNEL_19 //New//Original #define ADCx_CHANNELa_GPIO_PORT GPIOA//Original #define ADCx_CHANNELa_PIN GPIO_PIN_4#define ADCx_CHANNELa_GPIO_PORT GPIOA //New#define ADCx_CHANNELa_PIN GPIO_PIN_5 //New //Original #define ADCy_CHANNELa ADC_CHANNEL_18#define ADCy_CHANNELa ADC_CHANNEL_3 //New//Origina

in stm32wb55, After generating p2p configuration, #include "ble_types.h" should add manually in p2p_stm32.h file.

Hi,We are using your part# LSM6DSVTR ,Can you please advise for top marking.ThanksJay Trivedi

HiChip：stm32h723Peripheral:FMCConfiguration:FMC_NORSRAM_DEVICE , FMC_NORSRAM_EXTENDED_DEVICE;FMC_ACCESS_MODE_AFMC_ASYNCRONOUS_WAIT_ENABLEIf the extended device(eg. FPGA) do not assert NWAIT，the program on stm32h723 will crash. I want to know which register can set the timeout for the NWAIT signal to prevent a crash? Best regards,Andy Zhou

Hi all,I’m trying to use the external NOR flash (MX66UW1G45G) on the STM32U5G9J-DK2 board as the storage backend for a FAT filesystem using FileX.I came across the example “Fx_NoR_Write_Read_File” from STM32CubeIDE (STM32U5G9J-DK2 package), which appears to be doing exactly this — creating a FAT filesystem using FileX and LevelX on the external NOR via XSPI. However, it’s .ioc file is missing, so I can’t see how the XSPI interface and pins are configured.I built and flashed the example as-is, but the fx_media_format() call returns FX_IO_ERROR (0x90 in Hex and 144 in decimal). Could someone please guide me on the correct steps to:How to properly configure XSPI for the MX66UW1G45G in CubeIDE.The correct steps to use FileX and LevelX with external NOR flash as the filesystem backend.Thanks in advance!

Hello,I'm doing my machelor thesis, and I found a very interesting phenomenon. I deployed a Yolov8n from model zoo inside the N6 Nucleo Board NPU(by modifying the template project from the DK board and Input from the UART with CRC code to make sure the picture is send correctly.) the inference seems to be right. However, when I input the same data (same picture with same crc code), the output can be different!!???? Is this phenomenon right? or its because I messed up sth. when I change the project???????Also even if I deploy this Yolov8n inside CPU without NPU, the outcome is still different when giving the same input. (the reference seems also working correctly.) Is this also correct??? any explanation or documentation for this? (the mAP can have a 20% different when giving 10 same pictures) Also when using a mobilenet v2 the same phenomenon is also found both in CPU and NPU,( top 5 class is same ,but the confidence can have a difference up to about 20 %) please give me

Hello all,I have a custom board with an STM32U5A9 mcu with an external MT25QL128 flash for TouchGFX assets.I have a working loader for IAR Embedded workbench and I'm trying to port it to work with the STM32CubeProgrammer.When building as a normal project - that is a minimal cubemx project with just ospi and clocks enabled and with my ospi functions it runs fine, read/write/erase the flash without any issues.However, when I move it to the loader framework the init function crashes - I believe in a hard fault or some kind. It's difficult to tell for certain since debugging the loader is tricky.The cube programmer only tells me "Error: Data read failure".I realized that if I return early from the Init, no error is issued and the flash only read zeros - which makes sense because the ospi is not initialized yet.Thus I found out that the issue so far is on HAL_OSPI_MspInit function that was generated by cubemx.This part of the code returns 0: __HAL_RCC_OSPIM_CLK_ENABLE(); return 0; __HAL_RC

Hello, I'm currently writing a bachelor thesis regarding the model deployment inside the NPU. I'm writing about the theorical part of the thesis. And I was reading the RM0486 Reference manual. But I found one thing unexpected, from the page 1023, this figure have a I-TCM and D-TCM above the CPU and seems to have a connection with the NPU and CPU. However, I never have any experience with these storage devices... I have the project to make right inference inside the NPU which is modified from the get started project of the DK Board, the CubeIDE project only activated the D and I cache explicitly in the code. (of course AXIRAM 3456 and XSPI...) but no codes regarding the I TCM and D TCM. from other documentations, I also have rare infos about them.  So my question is: Are these I-TCM and D-TCM used inside the get started project of the DK Board ? or are they used in the runtime without any explicit code? Are there more documentation about what does they do for the NPU ref

Hi,I am using HFDA80D Amplifier in my design.I need details regarding required input current for 12V input and 4 ohms 100W output.

Hi everyone,I’m currently working on integrating the ST25R3916B NFC reader into my custom hardware and would like to avoid implementing the complete driver from scratch in C/C++. Therefore, I’m trying to base my work on the X-CUBE-NFC6 software package provided by ST.Is this the right starting point for using the ST25R3916B as a standalone chip (not on an evaluation board)?I manually downloaded the full package from::backhand_index_pointing_right:https://www.st.com/en/embedded-software/x-cube-nfc6.html#get-software— because STM32CubeIDE didn’t seem to import all relevant source files automatically.Now I’m struggling a bit to understand which components or folders I actually need from the package to get the basics working.Also, in CubeMX / CubeIDE I can see the following configuration options (see screenshot).  However, I'm unsure what to select in terms of the “Board Extension” and “Board Part” settings. Since I’m not using any ST eval board, just the bare ST25R3916B, I don’t

I try to create vehicle GUI on STM32U5G9J-DK2, but I can't find CAN pin to send data out from board to another node in CAN bus. 

Hello everyone,I am currently using a custom NFC board based on the X-Nucleo-NFC08A1 that has the ST25R3920B MCU. I am able to perform OOB pairing (LE Secure Connections) using the example provided by ST in the software tools example. I can sucessfuly complete the bluetooth pair using a Samsung A12, however if I use other smartphones like Google Pixel 6, Xiaomi 14T or even Huawei the pairing does not complete.I have tried this with other manufacturers libraries and software and it works for all the smartphones. After inspecting the memory of the tag I found out they use a "Handover Select" record with an "Alternative Carrier" inside. I dont't know if this is why it is not working with other smartphones.Could someone explain this better, and if so, how do I set this additional records?Best regards.

I use the STM32CubeIDE Version: 1.18.1 and the stm32g030k8.I have a hardware that uses a firmware. This firmware correctly returns the values of the ADC. The ADC is linked to a DMA. Channel 4 == 2545 (this is a voltage divisor) 12.5 voltsChannel 10 == 1 (this is connected to a current shunt resistor) No current, then almost 0. Channel Temperature == 929Channel Vreference == 1506   I develop a new firmware with the very same hardware (not just same design but same device). I apply debug optimization. I use ADC1 with the DMA, first I use the ioc file to set up the ADC and then I copy the MX_ADC1_Initfrom the other stm32cubeide project. Yet It does not return the same value from the external pins. Why is that?  Thanks for all.      

Hello, so I was originally using printf with uart3, and that seemed to work fine. The characters were being printed as expected on a PuTTY terminal that I was using. I was using the following code:/* USER CODE BEGIN PV */ UART_HandleTypeDef *uartHandlerDebug = &huart3; // UART bank used for communication with computer for debugging /* USER CODE END PV */ int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Configuration--------------------------------------------------------*/ /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /* USER CODE BEGIN Init */ /* USER CODE END Init */ /* Configure the system clock */ SystemClock_Config(); /* USER CODE BEGIN SysInit */ setvbuf(stdout, NULL, _IONBF, 0); //! Disables buffering for stdout HAL_Delay(1000); // Allow previous code to be erased /* USER CODE END SysInit */ /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_DMA_Init(); MX_USART3_UART_In

  Hi, Im working with the ST EDGE AI Developer Cloud and since the last monday Im having some problems with the benchmark, they got stuck into this infinite loading...  Its still possible to download the final files, but the benchmark tools are really useful to know if the model is going to work "well" in the boards.     

as per data sheetbelow is the timing details for read write operations for m95m04-dr:Write timeByte write within 5 msPage write within 5 mscan we operate or perform operations in 1microsecond or so? if yes what about write/read data integrity? Regards,Sumit

Setup: NUCLEO-H503RB with X-NUCLEO-IKS4A1, using STM32CubeIDE. To familiarize myself with I3C, I am playing around in this setup and have some source code which causes I3C interaction between the controller (Nucleo board) and two targets (daughter board). I have a logic analyzer attached. What I cannot get to work is the "direct RSTACT", i.e. configuring one of the two targets to reset itself. After everything has come up, I expect the targets' default reset action to be "1", i.e. I3C peripheral reset. After successful dynamic address assignment to both targets, I send a direct RSTACT (CCC 0x9A) to one target, configuring the reset action to be "0" (no reset), followed by the reset pattern. I would expect the other target to lose its dynamically assigned address and respond to a subsequent ENTDAA. But no one responds. Note that in my screenshots, the decoder is set to I2C rather than I3C (not supported) but it's still helpful. Tell target with dynamic address 70 to not reset when

Hi,I have an STM32N6570-DK evaluation kit that I'm using to build a small ML demo. NanoEdge AI studio has the possibility to record a dataset using the Data Logger functionality. However that currently does not support my evaluation kit, or at least I am not able to find such option. I was hoping to use the inbuilt microphone to record sample data for my demo. Will the STM32N6570-DK be supported in the near future, or can I somehow make this work myself without official support?

Hello,I am currently using the NUCLEO-WB15CC to test STM32CubeMonitor-RF.I imported the BLE_TransparentMode example to be able to use Monitor RF. Everything works perfectly when using the default USART1 interface.I also tested the communication using an FTDI cable instead of the NUCLEO’s embedded ST-Link virtual COM port (by removing the RX and TX jumpers), and the FTDI connection works fine with USART1.For my project, I would like to use LPUART1 instead of USART1 to communicate with Monitor RF. CubeIDE seems to allow switching between UART instances easily. I configured LPUART1 in the same way as USART1, using DMA and the same settings. The configuration compiles and programs correctly, and I have successfully flashed the firmware.I am using the same FTDI cable, connected to the connect LPUART1 pins (RX: PA3, TX: PB5), but I am unable to establish any connection with CubeMonitor-RF.(Of course, I double-checked the RX/TX wiring and tried swapping them just in case.)If I use (RX: PA3, T

Hey,I'm using the STEVAL-STWINKT1B sensor to log data, and I was wondering if there's a way to do it without connecting via BLE (through the ST BLE Sensor app on iOS). I know it's possible to log data using NanoEdgeAI — which I’ve successfully done — but I was hoping there might be a simpler method.Specifically, is there a way to just power the sensor with a battery, insert the SD card, and start logging data by pressing a combination of buttons (like holding down the reset button for a few seconds, etc.) — without needing any app or external interface?Best,Anthony

I'm trying to build a STM32U5 (THREADX_ARCH = cortex_m33) project that use FileX (https://github.com/STMicroelectronics/stm32-mw-filex) with CMake.I encounter an error that say "FileX/ports/cortex_m33/gnu" is not an existing directory.Why Cortex m33 is not supported by FileX ?
