Hello,I am using the model from 'STM32 AI Model Zoo' located at 'stm32ai-modelzoo/image_classification/pretrained_models/mobilenetv2/ST_pretrainedmodel_public_dataset/flowers/mobilenet_v2_0.35_128_tl' for image classification. I have installed and tested the Device Application using the Template Application in X-CUBE-AI 9.0.0.I verified that the input data is correctly received, and I understand that the output should be quantized integer values according to the quantization results. However, I have found that all the output values in the first tensor of the model's data_outs are 0.- 1. Can this happen if I don't use the stm32h747i board?- 2. Did I misunderstand and write the post process function incorrectly?Thanks 

Hi,I try to build up a HAM LoRa APRS system with STM32 and I don´t receive any messages in my gateway. For testing purposes, I use an 868 MHz gateway and an RAK3172 module.

for custom board of STM32mp157f-dk2 version.the same code i run in the custom board it work but, the error " it stuck in the power supply type C not detected"  by Uboot , TFA and OPTEE work fine but in u-boot it stop so i can hand this situation and , any bypass mode is there.and where i can modify this one.Actually i remove the type C connector and in place of type C i attached the only two pin power supply in custom board ,after u-boot boots the MPU  , it prints the error on type C power supply  not detected, so in my code where i need to modify the code, i am using openSTlinux distribution package (STM32mp157f-dk2).

Hi Clive.I am running a project on the STM32H750VBT6 controller with external W25Q128 QSPI memory.I need to write data to flash. Your bootloader:https://github.com/cturvey/stm32extldr/blob/main/h7_w25q128/W25Q128_STM32H7XX-CUSTOM27.FLMdidn't work.I decided to write my own. It works, but strangely. It works at first, then it can stop workingIt can be cured by commenting out an unused function or changing the optimization type.It works for a while, then it stops. And I have 2 identical boards. It works on one,on the other it doesn't.I ask for help. I am attaching my project. What could be the problem?If not, can you fix your bootloader W25Q128_STM32H7XX-CUSTOM27.FLM ?It doesn't work for me.

Hello All,   I am reaching out to seek assistance regarding an issue I encountered while attempting to upload the BLE stack to my STM32WB device using the STM32 Cube Programmer.

I want to align digits without prepending with 0. So %3d instead of %03d. 000:00 100:00 10:00 1:00 With non-monospaced fonts, such as verdana this doesn't work due to the space character not having the same width as digits. I don't care about the width of punctuation. All digits do have the same width in most non-monospaced fonts, but the space differs.Unicode has different space types. Such as U+2007 "FIGURE SPACE" (https://jkorpela.fi/chars/spaces.html). This character should be a space character with the same width as a digit. Not all fonts support this character(https://www.fileformat.info/info/unicode/char/2007/fontsupport.htm). Arial is non-monospaced, but supports this character.Below is a demonstration with ARIAL with regular space and "FIGURE SPACE"WWW:WWlll:ll000:00100:00 10:00  1:00WWW:WWlll:ll000:00100:00 10:00  1:00As you can see (if the forum renders this correctly) the width of characters differs, but digits have the same width. And the "FIGURE SPAC

Is there any example on STM32H503 nucleo board, how to handle USBX with storing/reading data from pendrive?

Hi, first time using DMA so just reading various datasheets and posts. But something is not clear.   I would like to use DMA with UART to send large amount of data through the serial port while keeping the CPU as free as possible for other intensive tasks. So I am thinking of using HAL_UART_Transmit_DMA() but, because of the large amount of data that needs to be sent, I might need to call HAL_UART_Transmit_DMA() very often with the risk to it being called while the previous HAL_UART_Transmit_DMA() call/operation is still running.   Is there a way to somehow append - or perhaps automatically queue - the new data right at the moment I need to so the code can keep executing, instead of having to wait and check for when the current DMA action is completed (whether inline or through interrupts)?   Also is there a limit to the data size I can send with HAL_UART_Transmit_DMA() ?   Perhaps using two channels? Thank you

Hello,My new NanoVNA-H4 arrived today.  I immediately set out to update its firmware to the latest version (v1.2.29) but have been unable to get the DFuSe_Demo_V3.0.6 bootloader to "Choose" the DFU file (NanoVNA.H4.v1.2.29).  I get a "This file doesn't have a correct format..." error every time I make the attempt.  I therefore cannot update the firmware in my new NanoVNA. How can I fix this problem?See attached screenshot.Thank you,JS2OLO

Hello, I have created a project in TouchGFX 4.24 based on the STM32U5A9J-DK I am using. I generate the code in TouchGFX and then import the project into STM32cubeIDE 1.16.0. The code will build and compile and I am able to upload it to the board and everything works as expected.  When I open the .IOC file to add PE2 as a GPIO_EXTI2 interrupt and generate the code the project will no longer build with the following 2 missing files:C:/ST/STM32CubeIDE_1.16.0/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.12.3.rel1.win32_1.0.200.202406191623/tools/bin/../lib/gcc/arm-none-eabi/12.3.1/../../../../arm-none-eabi/bin/ld.exe: cannot find -l:libnemagfx-float-abi-hard.a: No such file or directoryC:/ST/STM32CubeIDE_1.16.0/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.12.3.rel1.win32_1.0.200.202406191623/tools/bin/../lib/gcc/arm-none-eabi/12.3.1/../../../../arm-none-eabi/bin/ld.exe: cannot find -l:libtouchgfxnema-float-abi-hard.

Hi, I have a problem when using scroll list as a menu list. I have a custom container( a textArea and a background image) for this scroll list. It works good but this lagging problem. I'm running on NucleoG071RB + X-NUCLEO-GFX01M2, I know this resources are quite limited in this board. I tried to make the background as a 200*4pix thin line, still has this lagging problem.Any thoughts? thanks in advance.What I haved tried:1- make the background as small as possible (not working)2- setAnimationSteps(0), (not working, not related to this problem)I uploaded a video to make it easy to get the intuition of this problem. 

I removed the STlink of the NUCLEO F722ZE board and wrote it, but there was a clock error, so the program itself is not working It worked normally when there was Stlink, but it's not working I set it to HSI and used it, but it didn't work, so a clock issue occurred to switch to HSE, so I thought it would be okay to just debug it, but at some point, the clock didn't work, so it didn't come out of stop mode I set it as an rtc alarm and woke it up, but it seems like a clock error when it stops after going well How can I fix this error? Stlink uses a lot of electric current, so it needs to be removed I removed only the stlink from the hardware, but this is the situation Original settings before removing STlink       Setting changed to clock error after removing STlink       This is the setting I used before, but after removing the STlink, the HAL_RCC_OscConfig(&RCC_OscInitStructure) error handle occurred in this part   void SystemClock_Config(void

Hallo,I'm using U5A9NJQ demoboard with FILEX. I have something that doesn't work, the first time I write on a file, all is correct, but if I rewrite on the same portion of the file, the writing seems to be correct, but, when reading, the content hasn't changed. Do you have found something similar? Is there a project where is possible to have the FILEX working with this demoboard?Thank you

I'm working on a design that involves using an STM32F04 acting as a USB-CDC to RS232 bridge to communicate with the main logic of the system, in preference to dedicated RS232 USB chips that require dedicated drivers. In addition to this, the STM32 is also driving an I2C device and bridging it over SPI to the main logic. All of this works well. The I2C is also connected both to the CPU and the main logic, though the main logic does nothing with this interface normally, but allows me to test the issue below.When I came to investigate having the main logic update the firmware of the STM32, I identified an issue - though I was able to boot the STM32 into its ROM bootloader, I can't actually access it - it doesn't respond on the I2C or the UART.Having consulted AN2606, it lists the following ports as used by the bootloader in the STM32F04:- PA11 (USB-)- PA12 (USB+)- PA9 (USART1 TX)- PA10 (USART1 RX)- PA14 (USART2 TX)- PA15 (USART2 RX)- PB7 (I2C1_SD)- PB6 (I2C1_SCL)However, the TSSOP20 packa

I am triggering adc every 100us in dma and getting data in adc callback. I am triggering adc with hrtim compare 3. //hrtim cmp3 event call back{//reset a pin.} //adc conversion call back{//set a pin} for some reason the reset pin is working every cycle but set pin skips its cycle.It means adc call back not working every cycle?What can cause this kind of behavior?

Hi,I am using built-in usart bootloader on stm32g0. And I am also using the same usart for communication in my user app. I enabled the bootloader via boot option bits. When I start the debug session, I can see the flow stepping over through the program flow, going over HAL_Init(), SystemClock_Config(),  MX_GPIO_Init() and MX_USART1_UART_Init(), and then the program flow comes to my first "HAL_UART_Receive(..." function. It is at this function that the program jumps to the Bootloader and the bootloader starts to respond to my uasrt commands. After I exit the bootloader, via the "Go command(I use address 0x08000000)", the program flow stops at breakpoint I have at "HAL_Init()" and then when I step over again, I see that as soon as I hit the "HAL_UART_Receive(..." function again, it goes back into bootloader. So, my thinking now is that after I exit the bootloader, I should modify the boot bit (nBOOT0) in my user code, to disable it and then enabling it again
