Hello, I am using the NUCLEO-h745ziq board. I am using two board for SPI loopbacking.One board as master and one board as SLAVE. Can we use the two debug window at time. Because I launch the one stmcubeIDE window 1.5.1 and another from stmcubeide 1.6.1 because i have only one drive C. When i debugging the two board, one board debugging ic completed when i try to debug second borad i get the error of GDB server failed. I am unable to undestand why it is shown .Becuase my two board independantly working when i debug it one by one.Can someone please helpme?

Hi, I have a strange situation I can't figure out. I'm new at DMA so I just follow directions as  best I can without a full understanding. Right now, my setup is more or less working for a few months. But today I encountered a problem. I am using UCPD with DMA. Somehow UCPD starts sending data that is equivalent to all 0s. Basically, the data being sent to UCPD by the DMA is all 0s. UCPD encodes this and sends it out over the data channel. Its the correct number of bytes. Also, the preamble and header which are made by UCPD are both correct. I've checked with a scope to verify what is going out. And I've checked with a debugger to verify what is going into the DMA.Can you think of any reason why the DMA would transfer just 0s to the peripheral? Or why the peripheral would receive 0s? Does the DMA buffer need to be volatile? Makes sense that it would need to be but following the STM example code for UCPD their DMA buffers were not volatile.. Also I should point out this isn't

Hello,I've discovered the following anomalous behavior when attempting to use the STM32F103 Nucleo board:Pushbutton interrupt code will not execute if the RTC is active with NVIC EXTI13.  I've noticed that the RTC tamper PIN is also assigned to PC13 but I've made sure that the output selection is disabled and RTC tamper is deselected inside CudeIDE/CubeMX window.  If the RTC is activated with NVIC EXTI13, I measure zero volts across the appropriate pushbutton (pushbutton not depressed) pins (without the RTC activated the voltage across the same pins is 3.3V). My initial GUESS is PC13 is being reconfigured as an open drain output and being pulled low when the MX_RTC_Init is executed? I've tried to use the debugger to read the appropriate register and bit but I keep receiving a read error.  If I comment out the MX_RTC_Init function and download the program I receive correct functionality from the pushbutton but only after a computer reboot.I've also tried to execute the MX

I am using the STM32WB55 microcontroller for my product. I want to connect more than one module to my Windows laptop. When I pair one module, it pairs correctly, but when I try to connect another module with the same firmware, it shows the message "Try to connect your device again" and does not connect. I have tried changing many things, but it is still not working. Where do I need to make changes so I can connect both devices with the same firmware to my laptop?

Hi,I am implementing CDC ACM on STM32C0x series with USBX standalone. I searched for many examples but could not find a single example for USBX standalone for CDC ACM. There are examples with USBX standalone for HID Mouse. Wherever, I find example of USBX for CDC ACM, it is always using ThreadX.Can anyone please point me to example for USBX Standalone for CDC ACM?Thanks,Pradeep

Hello STM32 developers,I/m using STM32CubeMX 6.14.1I noticed that in middleware the selection "USB_DEVICE" has disappeared.Instead, "USBX" is listed, however it is for RTOS, and I don't use RTOS, so I'm left with nothing.I think the STMicroelectronics USB stack would still be available, somehow:https://wiki.stmicroelectronics.cn/stm32mcu/index.php?title=USBX_overview&oldid=10172Besides offering STMicroelectronics USB stack, USBX, the Azure RTOS USB embedded stack is currently supported and offered with a set of applications running on STM32 MCUs. How can I use the STMicroelectronics USB stack > "USB_DEVICE" instead?Do I need to install some software for it?

I’m currently working on a project that involves I2C communication using the STM32H750B-DK  but I’m having trouble identifying which I2C peripheral (I2C1, I2C2, etc.) is connected to the Arduino I2C pins (SDA/SCL) on the board.Unfortunately, I couldn’t find the schematic diagram of the board or any clear documentation that specifies this mapping.

Hi all,I am using CubeMX 6.14 to generate an OpenAMP project for the STM32H747I-DISCO board. When I build the project, I receive the following warnings, and it results in an 'OpenAMP create endpoint' error at runtime. I used the same code and project created with CubeMX 6.12, and it works fine. Therefore, I suspect there might be an issue with CubeMX 6.14. Could someone please advise me on how to generate a working OpenAMP project using CubeMX?arm-none-eabi-gcc "D:/TouchGFXProjects/STM32H7_TUT/Drivers/STM32H7xx_HAL_Driver/Src/stm32h7xx_hal_rcc.c" -mcpu=cortex-m4 -std=gnu11 -g3 -DDEBUG -DCORE_CM4 -DUSE_HAL_DRIVER -DSTM32H747xx -DUSE_PWR_DIRECT_SMPS_SUPPLY -DMETAL_INTERNAL -DMETAL_MAX_DEVICE_REGIONS=2 -DRPMSG_BUFFER_SIZE=512 -DVIRTIO_SLAVE_ONLY -DRPMSG_BUFFER_SIZE -DNO_ATOMIC_64_SUPPORT -c -I../../../CM4/Core/Inc -I../../../Drivers/BSP/Components -I../../../Drivers/STM32H7xx_HAL_Driver/Inc -I../../../Drivers/STM32H7xx_HAL_Driver/Inc/Legacy -I../../../Drivers/CMSIS/Device/ST/STM32H7xx/Inc

Hi,I'm using STM32CubeIDE 1.18.1v, which includes STM32CubeMX 6.14.1v, and I'm seeing unexpected behavior when working with GPDMA1 on an STM32H5 device.When I configure a DMA channel with Request set to "Software", CubeMX generates full initialization code.However, as soon as I change the Request to any other peripheral trigger, for example TIM2_CH1, all of the DMA configuration disappears from the generated code. Only the RCC clock enable and interrupt configuration remain. Example 1 — Request = Software:static void MX_GPDMA1_Init(void) { /* USER CODE BEGIN GPDMA1_Init 0 */ /* USER CODE END GPDMA1_Init 0 */ DMA_NodeConfTypeDef NodeConfig = {0}; /* Peripheral clock enable */ __HAL_RCC_GPDMA1_CLK_ENABLE(); /* GPDMA1 interrupt Init */ HAL_NVIC_SetPriority(GPDMA1_Channel0_IRQn, 0, 0); HAL_NVIC_EnableIRQ(GPDMA1_Channel0_IRQn); /* USER CODE BEGIN GPDMA1_Init 1 */ /* USER CODE END GPDMA1_Init 1 */ NodeConfig.NodeType = DMA_GPDMA_LINEAR_NODE; NodeConfig.Init.Request =

Hello,Is there support for PAwR with BLE on the STM32WB10CCU5 chip? Additionally, I would like to know what methods I can use to send different data to multiple devices using BLE with this chip. If this chip does not provide the necessary functionality, could you recommend another STM32 BLE chip suitable for such an application?Thank you for your assistance.Best regards,Teoman

Hello,I purchased a set of Wireless charging evaluation boards (RX & TX) on Mouser.com for $160.The 2 board names are STEVAL-WBC86TX and STEVAL-WLC38RX. I use STSW-WPSTUDIO V1.8.4 software to try to connect to the board from my PC and get access to the register setting. But every time I click on the Connect button, there is the same error message appearing: "Unable to find any [RX]WLC38 device. Please check your connection again."  The issue is the same with both boards.But it seems the boards are working, because when I place STWLC38 on top of STWBC86, the boards are charging, because I can see the red LED on the receiver board, and Vout is 5V. So the main issue is the GUI.I cannot use the ST GUI to connect to any of the ST boards that I paid $200 for ! (with shipping + fee cost) My computer is Windows 11. And the board is properly connected through a USB-A to USB-C cable.I followed the steps from the user manual. The 2nd USB-C connector of

I would like to implement a HID composite device (e.g., mouse + keyboard) using USBX on an STM32U5.However, calling ux_device_stack_class_register() twice (once for the mouse and once for the keyboard) returns an error. I assume this is because USBX supports only a single instance of the HID class by default.Our existing product is recognized by the host as a composite HID device (with separate interfaces for mouse and keyboard), and I would like to replicate the same structure.My environment:STM32CubeIDE Version 1.17.0STM32Cube MCU Package for STM32U5 Series 1.7.0Board: NUCLEO-U5A5ZJ-QCreated via:Project Explorer -> New -> STM32 project -> Board Selector -> NUCLEO-U5A5ZJ-Q -> FinishUSBX middleware enabledChecked all HID class options in the middleware configurationIs there a recommended way to create a HID composite device (multiple HID interfaces) with USBX?Should I modify the report descriptor to include multiple Report IDs, or is there a way to register multiple HID

 Hello,I'm facing an issue while performing OTA firmware updates using the ST BLE Toolbox app. The image file uploads successfully in most cases, but quite often, the final confirmation pop-up (indicating completion or prompting for reboot) does not appear. Additionally, the BLE connection does not disconnect automatically after the upload finishes.As a result, the firmware gets stuck, and it seems the device is not transitioning out of the OTA mode properly. I suspect the problem might be related to BLE service handling in the firmware, possibly missing a disconnection trigger or final response from the app.Has anyone else faced a similar issue or can suggest what part of the BLE service code should be checked for proper OTA completion and BLE disconnection?Any guidance would be appreciated.Thanks in advance.

If I realize it is true, is it needed to solder SB12 in NUCLEO-WBA52CG board for using SWO as ITM_SendChar in printf debug? Thank you for helping!

Hello; I am very new to STM32 products. I have been working with the P2P_Server and P2P_client examples using the STM32WB05KZV6TR MCU.As I use the P2P_clent example in both the Nucleo board WB05KZ and a custom board and load the built image, the next time I try to download a new image I need to put the nucleo board into Bootloader mode(BOOT0 jumped to Vcc) and download the new image that way. The custom board that I am working with currently has no hardware way of putting it into bootloader mode therefore I cannot load a new image.My question is, why do I need to put the nucleo board into bootloader mode to load an P2P_Client image?, The P2P_server does not have this issue Is there a way to prevent this? thanks Fernando

My linked-list object's base address in memory is 0x200bffbc.   How can I save this address in GPDMA_CxLBAR register (that holds "the linked-list base address of the memory region, for a given channel x, from which the LLIs describing the programmed sequence of the GPDMA transfers, are conditionally and automatically updated")  when GPDMA_CxLBAR designated region for the address (LBA[31:16]) is only 16 bits long? Anyone can help please? 

Hello everyone,We constantly receive orders from our customers that they got some motors which their nominal speed, nominal voltage, and etc. are approximately similar to each other, but their Rs, Ls, Ke, and pole pairs may differ.They want us to design an inverter board in such a way that it can get these motors running, providing the capability to see if their motors are damaged or not, just by using a single board without the need to customize the firmware or the hardware for each motor. So, we need to somehow get pole pairs of the motor from the user, change it in the firmware and run the profiling process.For such purposes,What can we do by using ST motor control workbench?What are the related APIs to achieve this goal?Is this even possible?Thank you!

Hello everyone. Question about synchronous launch of three timers.Given:- CPU F0 or F4 or G4 (of course F103 is possible - I just don't like it, personal dislike);- three timers, each with its own operating frequency, Timers work via DMA, each with its own buffer for PWM generation;Task:- simultaneous launch of all three timers;Limits:- interrupts are prohibited, no interrupts;With the same frequency - there are no problems, they start at the same time, but with different frequencies, everything diverges. Tell me if there is a solution.

I feel duped right now.  I bought the P-NUCLEO-LRWAN3 kit yesterday from st.com directly as my starting point into embedded stuff. Today I installed CubeIDE and went to generate a new project for the NUCLEO-F746ZG included in the kit, and I get a message telling me the board is obsolete. The kit says the marketing status is "active", but when I look up the NUCLEO-F746ZG directly, sure enough it says it's obsolete and I should use the NUCLEO-F756ZG instead.Why is this package marked as active and still in circulation? I feel this is just a way to sell obsolete boards to people don't know any better. Yeah I should have looked up the each board in the kit individually before buying, but I guess I was just burned out from researching all these different boards and I decided to trust that the kit is legit. edit: Maybe the wrong board is listed in the kit description?  I hope that's the case.  It's due to arrive on Monday, so I guess I'll see then.

Hi there,I have the following setup duplicated thrice in my project - to select three distinct parameters to define an object.Each listLayout is programmatically populated with a number of items (buttons). One screen has 5 items, the other two have 6. Five items fit perfectly on a screen and don't require a scrollbar, while six items require scrolling to see the final item. However, none of the scrollableContainer display their scrollbar until I touch the screen, despite me configuring it to do so (at least, that's what I think "Show scrollbars" means):What am I doing wrong? How can I ensure that the vertical scroll bar is shown, by default, when I open a screen with more items than fit on a screen?Thanks,Julia 

Hey everyone, I'm working with the STM32H747I-DISCO board and trying to get it into USB DFU mode to flash firmware using STM32CubeProgrammer. However, the board isn't being detected, and I couldn’t find clear instructions in the documentation about how to properly enter DFU mode. If anyone has managed to get this working or knows the correct steps, I'd really appreciate your guidance. Thanks in advance!
