Hello,When I create a new project in CubeMX for the STM32H747I-DISCO board, I cannot see the X-CUBE-AI package when I click on "Additional Software". Is it because this board has 2 cores Cortex-M7 and M4? Somehow we need to specify on which core the network should run?In the user manual of FP-AI-VISION1 (UM2611: https://my.st.com/content/ccc/resource/technical/document/user_manual/group1/a0/53/9b/b7/f9/b5/4a/6f/DM00630755/files/DM00630755.pdf/jcr:content/translations/en.DM00630755.pdf), it is written that:"For users having selected dual-core MCUs for their application but running it on the Cortex®-M7 core only: when dual-core MCUs like the STM32H747 are not supported by the STM32CubeMX tool, they must select a single core MCU like the STM32H743 to be able to generate the code for the Cortex®-M7 core."So, if I generate an X-CUBE-AI project in CubeMX for, let's say, the STM32H743I-EVAL2 or STM32H743I-EVAL board, would that project compile and work on the STM32H747I-DISCO as well, without

I am using STM32 Cube MX to generate 32L443RCTx code.In function HAL_I2C_Master_Transmit always returns != HAL_OKAny ideas why?

I've been developing motor control code on a Nucleo-64 G431 board (64-pin) but the target product will use a 48-pin G431. I'm trying to wrap my head around how I migrate my project from 64-pin to 48-pin.Unfortunately, the existing project is implemented using the STM32CubeIDE V1.2, which I understand may make the transition more difficult.Any and all insights appreciated!

Microcontroller may be; STM32L0 or L4Required; 5% worst case over -5 to 50'C​The microcontrollers are quoted 1% accurate at 25'C but I can not find how accurate they over the ICs temperature range. I want to avoid trimming or fitting a crystal.​​The application does not require a lot of processing and includes battery power and charging so an Fxxx variant or other may be suitable if temperature range is specified?

Hi Problem. There are two screens, S1 and S2. The S1 has two buttons. GO to change screen to S2 and ON to set output pin. The ON button state is sent to main.c. I want to change the screen after pressing GO, but also the state of the ON button. How to do it? best regardsAndrzej

I am trying to call rtc alarm at regular interval and want to call some code in non polling mode at every rtc alarm is fired. I know this can be done with RTC alarm callback function. But when we are in standby mode this call back function is not fired i think. I have tried it callback function doesnt work in standby mode but it does work in run mode. Kindly help me to solve this issue. MCU: STM32L412RBUsing CubeMX HAL

Hi,If we have multiple versions of HMI software developed using TouchGFX framework then how can I upgrade it from version 1 to version2 using USB drive?What steps are involved in this implementation?BR,Shree

Hello guys good day. May I ask for your advise regarding the code to interface a slave bluetooth to STM32F103C8. I bought this HC05 module and connected to the UART lines of the MCU. Baud of communication set to 9600. I am trying to enable an LED connected to the MCU output PA0 through the mobile Bluetooth. However I could not activate the LED. Appreciate if you could give me some advice. Attached is my code below. I use CubeMX to generate the code. Thank you.  /* Includes ------------------------------------------------------------------*/ #include "main.h"   /* Private includes ----------------------------------------------------------*/ /* USER CODE BEGIN Includes */   /* USER CODE END Includes */   /* Private typedef -----------------------------------------------------------*/ /* USER CODE BEGIN PTD */   /* USER CODE END PTD */   /* Private define ------------------------------------------------------------*/ /* USER CODE BEGIN PD */ /* USER CODE END

Hi, I set the sensor to 1G scale, data rate 104 Hz, while tilting from 0 to 20-25 degrees it gives sensible readings. Over that it just always shows 1G acceleration, so 45 degree angle shows as 89.Any hints on how to fix that, or my copy might be defective?

My controller can be waked up from Standby mode by Alarm A or Alarm B: Alarm A every day and Alarm B every minute. Are there any flags (or another means) to know, what event (Alarm A or B) was cause of the waking? That is the problem, because all registers (excluded PWR_CSR and RTC Backup) "dying" after MCU entering in Standby mode...

I'm not able to connect the NUCLEO-STM32WL55JC1 board (Updated FW today to V3.J7) to the STM32CubeMonitor V.1.1.0 ​Fun facts: Blink connection test works and the firmware is reported correctly in the connection config box.​Error message reads: "not connected | JTAG/SWD error/f5) In addition: Please fix the copy & paste bug of the Mac version (1.1.0). Known for at least 8 months.

I am attempting to use blockCopy to copy a block of memory. I have used it in the past, but with latest version of TouchGFX, for some reason I am now getting a compile error on the following generated function:bool TouchGFXGeneratedHAL::blockCopy(void* RESTRICT dest, const void* RESTRICT src, uint32_t numBytes) { return HAL::blockCopy(dest, src, numBytes); }Below is the error I am getting on the line HAL:blockCopy(dest, src, numBytes);../TouchGFX/target/generated/TouchGFXGeneratedHAL.cpp:85:15: error: 'blockCopy' is not a member of 'touchgfx::HAL'Any ideas?

I modified some functionalities using the MX interface in the STM32CubeIDE, saved and generated a new code and my core/src folder is gone.I've seen people complaining about this problem on older releases.Tested in another project (modifying settings in the MX interface and generating code) and the problem did not happen. What might be wrong with this specific project? I've been working on it for a long time and never had any problem.Right now I have Version: 1.4.2 Build: 7643_20200813_1322 (UTC), tried to update but no updates available.

I made a UART project in STM32CubeIDE. Cube generated the necessary UART initialisation code and created UART_INIT() function (or something like that) in main(). The project worked.Then I decided to add DMA. I regenerated the code and couldn't find DMA initialisation in UART_INIT(). I found out that this code was generated in another file in UART_MSP_INIT() function (or something like that). My questions are:Why does Cube generate this code in another file? Why not in UART_INIT() or DMA_INIT() in main()?Do I have to explicitly call UART_MSP_INIT() in main() by myself? And why doesn't Cube do it automatically?I found out that GPIO alternate function configuration (for UART) was also made in UART_MSP_INIT(). But I did't explicitly call UART_MSP_INIT() before using DMA. So why did UART work if the pins were not configurated?

I just received an STM32L4P5 Discovery board to evaluate eMMC for the STM32L4. In the firmware package for the STM32L4 there is an example project, "FatFs_eMMC_Standalone". I have built the example, however, when I try to run it the application halts in "initialize_monitor_handles". (SIGTRAP Trace/Breakpoint Trap)Seems there is perhaps an option missing in the project, can anyone help me to resolve this please.

I can't reach the site to download open stm32 system workbench. My emergency!

Hi!.I'm developing an Android app to read and write info into ST25DV64K.For the moment, I'm using the folowing functions of ST25SDK: com.st.st25sdk.NFCTag readBytes() and writeBytes() and they work properly.Now, I need to protect the reading and writting in ST25DV64K with password and I need to know which ST25SDK functions I can use.If possible, I would like to have a piece of code where I can see how the functions work.Thanks in advance!.

When i open an example project everything works OK. When i create a project using CUBEMX or the IDE i see a limited number of drivers. Working with STM32F411RE. I don't see any LL Drivers.

using Nuleo-401RE EVAL and x-cube-spn3-Stepper Motor sample project for expansion board. want to use UART2 and change FLAG pin to PA0. In STM32 Cube IDE I am not able edit back the pin configuration (.ioc not visible in sample project), how to change or re-assign the pins and re-generate code, need to go back Cube Mx? or can we do with Cube IDE we can modify pin assignement?

I haven't looked at the forum for a few weeks but just noticed that my full name is being displayed in a question I just posted, rather than my nickname.I would prefer that my nickname were displayed instead - could we revert to doing that please?Also, when I look at my profile, I can't find how to change my real name anywhere, although I can see where to change my nickname. Is it possible to modify my real name?

Hello everyone,I am using STM32L4R9AII with my custom board. When i start to develop my project, cubemx didn't support my MCU. So, I got discovery board project from Touchgfx and changed a lots of things to adapt it to my custom board.Now cubemx supports my MCU. I started to pass my project to cubemx project. My screen resolution is 400x400px via MIPI dsi. When i established my project from cubemx, it didnt work well. I put a box on screen, i could see the box color but every lines were different places. I digged down deep:I passed display width as 400px to cubemx. So, Touchgfx passed BlitOp.nSteps=400 to DMA2D.But GFXMMU module knows evey line has 1024px, but display is 400px. BlitOp.nSteps must be 1024. When i check my old project and discovery board project from new version of cubemx, i found code below to fix it:#define BSP_LCD_IMAGE_WIDTH (3072 / 2) #ifndef GUI_FRAME_BUFFER_WIDTH #define GUI_FRAME_BUFFER_WIDTH BSP_LCD_IMAGE_WIDTH   void TouchGFXHAL::setFrameBufferStartAddress
