Hi everyone,I'm trying to run inference with a TFLite model on a Nucleo-N657X0-Q board.The issue I'm facing is that the network returns a constant output for constant inputs - but the value of this constant changes each time I restart the application. When the input varies, the output also varies, but the values returned are not consistent with those obtained during the validation process.The model was quantized using a post-training quantization approach.I'm using AXISRAM4 and AXISRAM5, which have been correctly initialized and enabled in the main.c. I attach the .ioc file, the app_x-cube-ai.c file and the quantized tflite model for reference.Thanks in advance for any suggestions!

I'm trying to setup CubeIDE for STM32MP1 but cannot make it to see the OpenSTLinux SDK.Following this article:https://wiki.st.com/stm32mpu/wiki/How_to_install_the_Yocto_Project_SDK_in_STM32CubeIDEThe popup window that should allow to download the SDK does not show up. Instead there is another one that opens the SDK manager directly. So I downloaded the SDK manually. However this SDK manager fails to recognize the SDK directory.These two discussions seem to imply that entering path of the directory where SDKs are installed should be enough:https://community.st.com/t5/stm32-mpus-products/openstlinux-sdk-manager-can-t-find-updated-sdk/m-p/568427https://community.st.com/t5/stm32cubeide-mcus/stm32cubeide-cannot-find-openstlinux/m-p/621928However in my case the "Available OpenSTLinux SDK:" window is always empty. wincak@wincak-pc:~/ST/SDK$ tree . └── stm32mp1-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06 └── sdk ├── st-image-weston-openstlinux-weston-stm32mp1.rootfs-x86_64-toolchain-5

Dear ST expertsIf we want to use tcxo on stm32wl33, should we choose 1.8v or 3v3 power domain for the vcc of this tcxo?

Hello everyone! I am trying to use the ADC of my NUCLEO-F334R8 board. I want to read the PC1 pin (ADC12, channel 7). I try to initialize the ADC with the following code: void BSP_ADC_Init() { // Enable GPIOC clock RCC->AHBENR |= RCC_AHBENR_GPIOCEN; // Configure pin PC1 as analog GPIOC->MODER &= ~GPIO_MODER_MODER1_Msk; GPIOC->MODER |= (0x03 << GPIO_MODER_MODER1_Pos); // Enable ADC clock RCC->AHBENR |= RCC_AHBENR_ADC12EN; // Reset ADC configuration ADC1->CR = 0x00000000; ADC1->CFGR = 0x00000000; ADC1->SQR1 = 0x00000000; // Enable continuous conversion mode ADC1->CFGR |= ADC_CFGR_CONT; // Select channel 7 ADC1->SQR1 |= (0x07 << ADC_SQR1_SQ1_Pos); // Set sampling time to 19.5 ADC clock cycles ADC1->SMPR1 = (0x04 << ADC_SMPR1_SMP7_Pos); // 12-bit resolution ADC1->CFGR |= (0x00 << ADC_CFGR_RES_Pos); // Select PCLK/2 as ADC clock RCC->CFGR2 |= (0x11 << RCC_CFGR2_ADCPRE12_Pos); // Enable ADC

Does the charger IC ever operate outside of the specified TX FREQ MAX and TX FREQ MIN limits?For example, if the limits are set to 100kHz and 148kHz and the charger is operating at either limit, would FSK cause it to change the frequency below this value? If so, how much would the frequency be exceeded?

Hello,I am using the VD56G3 connected to a STEVAL-CAM-M0l1.  There is a very small ribbon cable between the sensor and the connector on the CAM-M0l1 - roughly 5mm.  I am working on a mock-up of some smart glasses where I'd like to extend that cable to a considerably longer length - ideally 1 meter.  Is there a way to create an extension to this cable or a product that has a lengthened connection?I know that there is also a ribbon cable from the STEVAL-CAM-M0l1 which could easily be lengthened, unfortunately, the form factor of the STEVAL-CAM-M0l1 is not suitable for my mock-up.Any suggestions/recommendations as to how to lengthen this connection along with any pitfalls would be appreciated. Thanks,Dan Luka

HiI am working on an application with wide VIN from 6V-60V and the target VOUT is 15V 3A max.When VIN > 16V, L7987 should fit my application. Problem is that when VIN drops below 16V, eDesignSuite reports an error so simulation is not possible. It states on L7987's datasheet that in case the input voltage falls close or below the programmed output voltage, L7987 is able to work in LDO mode. Am I correct? See screen capture of the datasheet below.When L7987 works in LDO mode, does it mean the chip is able maintain Fsw with duty cycle lift to 100%?What is the max. current in LDO mode?Look forward to any comment.John  

I want to make this graphical interface, can you help me to do that and thank you very much

I bought a 1Set STM32F407VET6 Industrial Control Board from AliExpress to evaluate the STM32 MCU family but I can't find any information about it. 1Set STM32F407VET6 Industrial Control Board I've used many different Arduino, Teensy, ESP32 and other such boards with Arduino and VSC/platform.io IDEs in the past and I'm used to having to dig around for info, but I can not find ANYTHING on this board, although it is for sale on many sites.I've installed the Arduino STM32 libraries, but I don't know how to download firmware to it or the I/O pins for any of the peripherals.Can I use a USB to TTL converter and if so, which pins do I connect to?What positions do the jumpers need to be in to upload firmware? What 'Mode' of firmware upload should I use?Are there any Example programs out there to get me going?Any help greatly appreciated, thanks.   

I have a series of interactions that shows/hide widgets on the screen. The interactions are basically triggered when a button is clicked and are all managed via TouchGFX Designer.Is there a way to trigger them via code, so like generate a virtual click on a button via code, instead of actually clicking the screen?For istance I have an interaction named yesHideSaveSettingsModalWindows that, when it's done, trigger another interaction called showSavedLanguagemodalWindowIs there a way to manually trigger showSavedLanguagemodalWindow ? 

Hello ST community,We are working on a 15kW Rectifier module for EV charging application. This module contains 15kW Vienna rectifier and 12kW DC DC converter, input voltage: 3 phase 415V, output voltage: 40V-120V. For this requirement, we are exploring project files (Altium files) and application notes around this power range. If you could please provide these documents, we greatly appreciate your support.Regards,Akash.

Hi.I'm porting the RFAL for NFC10A1 using ST25NFC_Embedded_Lib_ST25R200_1.7.0.I'm using the polling example. I have ported SPI, GPIO, and timer drivers based on my platform. I am using demo_polling.c as a basic template for my init and while loop functions and handlers.I have successfully initialized NFC10A1 board, but I end up in an infinite loop in the RFAL_TXRX_STATE_TX_WAIT_TXE state.The issue is that the ISR value read from NFC10A1 is 0 during this state. I have enabled RFAL_FEATURE_NFCA and ST25R_POLL_IRQ inside preprocessor. I have added various debug logs trying to figure out what make the system stuck. The log is attached as a zip.I tired looking at it with a logic analyzer (CH4 being the ISR pin) and discovered that despite ISR pin being pulled high, there was no proper reading of the ISR registers on NFC10A1 (which can be seen as no new SPI transmission occurred afterwards). I'm not sure why this is happening because ISR is clearly being read during system ini

Hi!I have a question about calibrating vl53L4CD and using a coverglass. I am doing experiments with a sample flat panel from Gilysmo, and I have noticed that if the panel is 2-3mm from the sensor, the calibration doesn't compensate for it. It looks like it just ranges to the glass and that's it. Is that normal? What is the maximum distance the glass should be from the sensor? Or perhaps I am doing something wrong?Thanks!

Hi there!Im new with ST MCUs and im using a Nucleo F429ZI, i have some documents and one of them is the 'nucleo-f429zi.pdf' but is too short and doesnt have too much informationIm working with user push button connected to PC13 but i want to know if this button has an external pull up/  pull down resistor on the board, and if doesnt i guess i have to set it by softwareWhere can i found schematics or additional information like this for this board?Also you would help me if you tell me if PC13 has a pull up/down resistor on the boardThanks in advance!, sorry for my english, not a native speaker

Hello Experts,Is it possible to view the memory allocation in a nice GUI format, something like this: (see image)The image is an example of what i am looking for (from code composer studio IDE).Basically it autoloads the data from .map file and displays it graphically!, cool thing here is that we can see where functions and variables are located along with its size and its loading addresses. for doing any analysis.Analyzing large .map files directly can sometimes be cumbersome. 

Hello,I am trying to update some code to use UART with DMA for receiving instead of the polling method.I want the implementation to work for messages of unknown length so I use the HAL_UARTEx_ReceiveToIdle_DMA function.I know that the maximum message length i can receive is MAX_LEN (=1024) so I call HAL_UARTEx_ReceiveToIdle_DMA(&huart2, my_buffer, MAX_LEN)The problem I noticed is that sometimes when I get in the HAL_UARTEx_RxEventCallback(UART_HandleTypeDef *huart, uint16_t Size) , the value of "Size" is equal to 1 even though I send 5 bytes in the UART. From what i understand, that this is because in the HAL_UART_IRQHandler (that is called when the line goes IDLE), there is this code:[...] /* Check if DMA mode is enabled in UART */ if (HAL_IS_BIT_SET(huart->Instance->CR3, USART_CR3_DMAR)) { /* DMA mode enabled */ /* Check received length : If all expected data are received, do nothing, (DMA cplt callback will be called). Otherwise, if at least one data has already b

Dear,Setup:We using a STM32H7B0 100pins.We use 1 ADC input at 1M samplesConfigured as 16bit, differential input, with an offset of 32768.We use a Vref of 2.5V.The other side of the differential input is 1/2 of Vref (buffered with a opamp)To sample the data of the ADC we use a DMA circulaire mode to internal memory.When we measure our signal we seen many spikes on the samples.With the scope is the input signal very clean.Also we use a opamp to buffering the analog signal before it get tot the ADC input.The opamps we used are LTC6256We cannot understand why we seen all these spikes.What are we doing wrong here or is there an explanation for this phenomenon? Thereby when we changes our sample rate to 100Ksps it has the same effect.Also when we change the ADC input from differential to single ended. regards

Hello everyone, I encountered a problem with overwriting OTP memory both from a user application and from the stm32 programmer.I write data to the OTP cell, close the memory using standard hal functions, turn off the power of the debug board, turn on the power, go to the stm programmer and see correctly written data.After that, I try to change one of the memory cells and the cube programmer gives me an error (which is correct, since this memory cell has already been written once). I close the error windows and read the memory, after that I see that the memory is CHANGED, but to a random number. This is repeated only once, that is, the cell can be written twice both from the PROGRAMMER and from the application.I tried to write the same data but to the addresses 0x08FF F000, 0x08FF F040, 0x08FF F080, and all the time the secondary cell write was triggered (the bottom picture).I also encountered a problem with calling NMI_Handler and HardFault_Handler when trying to read memory from the a

Need some clarification on implementing the DFU functionality on STM32L412KBU3.According to the note in AN2606 (page 350), it states: "VDDUSB IO must be connected to 3.3 V" however, on the STM32L412KBU3 (UFQFPN32) the VDDUSB pin does not exist.Currently, VDD is powered by +1V8 on my application of the STM32L412KBU3.Will I have any issues with DFU moving forward?

Hi all,Coming from Nordic nRF52840, I have a project that uses a Joystick.I bought two Nucleo boards, the P-NUCLEO-WB55 and the NUCLEO-WL55JC1 to test Radio communications.My Joystick of course uses 2 channels (X and Y), uses 2 GND pins, but also uses 2 pins for 3.3V (VDD). Now after checking the official Nucleo manuals, I can find only one 3.3V  VDD pin.Is that right? Those development boards offer only one 3.3V pin?If yes, what are my options?Power the joystick with that unique 3.3V VDD pin? Just like it's done on most small boards (like the blue pin)?Thanks for any light and help you can provide.Steve Jordi

Hi, I have problem with my SPI peripheral. For generate inicial code I used STM32 Cube IDE Version 6.14.1, and programming IDE STM32 Cube IDE Version 1.18.1.Description of problem:1.I want simple to check loop with transmit and receive data, but when I do that I always have 0 or 255 in receive register. I tried the same thing with UART, and it works.2.On SCK I don't have clock, I try with oscilloscope to see but nothing. In attachment I leave full project and video, please can someone check and say me some advice.
