STM32CubeMX (MCUs)

Hi,I cannot enable SPI1 interface in CubeMX with STM32F427.I only see the message "I2S1" must be disabled":But I2S is not used in my project.In Pinout view it is possible to select Pins PA4 to PA5 and PB5 for SPI1-sugnals without error messages.Whats wrong here? 

Because I don't want use HAL , but want use the possibility to configure pins with CubeMX

HiI will setup an application on my STM32H743ZI2 which should make a Client socket connection using the LwIP and netconn. When i'm uisng the LwIP HTTP Server Netconn RTOS example i can make it work and the Netonn API functions is working,If i instead of uising the example is starting a project using CubeMX and Enabling the LwIP, activating the FREETOS, enabling the CPU iCache and DCache.In the LwIP settings i activate the LWIP_NETCONN (NETCONN API) and checking that the follwing, described, is set correctly     LWIP_NETCONN (NETCONN API)Diagnostic:Dependency: Use NETCONN API requires NO_SYS=0 and MEMP_NUM_TCPIP_MSG_API>0 if MEMP_MEM_MALLOC is disabled.Parameter Description:When this parameter is enabled, Netconn API is enabled (require to use api_lib.c).   I'm then generating the project to run in Keil and in the main. c i #include the api.h, in lwipopts.h i define the LWIP_NETCONN.

Hello, I get this error can't figure this out. Any ideas?

Hello. I have been dealing with USBx host HID application for a while trying to find a soluction to my problem but despite that I dont know what else to look for to make it work. I'm working with Cube 6.9.2 and with its lastest library STM32Cube_FW_U5_V1.3.0. on a STM32 U575 microcontroller. I do not use USBPD, but I have seen the examples are provided, and in base to that I try to aply ir to my own project not using that specific library. Working with threadx. Clock configuration for USB is correct at 48Mhz, and USB HAL_HCD_IRQHandler is being called if I plug a keyboard.  The problem I have is that no matter what I do, always ends calling "ux_host_error_callback" and logs "UX_DEVICE_ENUMERATION_FAILURE". Any ideas as what to to to solve it are welcome.Thanks

I was wondering if multiple team members are modifying this file,what is the clean way to do a merge this file using Git? I am pretty sure STM Community is using CubeMX and there should be a way to update this file by multiple people and merge the changes without messing up the project.Any suggestions/comments are welcome.Thanks

Hello.To generate a multiplatform code I defined a SW architecture and packaging as follow :Build system :Vendor package can use the cdt project to generate the BSP (cdt builder is the only toolchain supported for system init code generation )Application is created as cmake project created by stmCubeIDE (new in stmcube ide 1.13) and links to the BSP.At first sight the APP would be a complete application and the  LLD a library providing only the HAL calls. That would mean that the APP hosts :Startup codeLinker scriptInterrupt.I am not sure the HAL could work with independently defined interrupt handler so I let those be part of LLD except the linker script (present but not used).The LLD package contains :System init (peripheral and clocks, interrupt handler, startup code)The main() (that can be changed though, but I’m lazy about calling the init function in the right order).Progress summaryIssue to create the HAL as library : it needs to be configured as a full binary.

I feel like I'm missing something basic here. What is the fastest way to configure many pins for GPIO in CubeMX? I have over 100 pins I need to configure and the only way I know how is somewhat tedious.For example, I need to make the entirety of PORT D, E, G, I, and J pins all GPIO_Output. The best way I've found is to use the search bar at the bottom of the Pinout view in CubeMX, search for PG0, then click on the pin in Pinout view, select GPIO_Output, then right-click on the same pin, select Enter User Label, and then type in my label.Is there a way to just get an alphabetical list of all the pins, PA0, PA1, PA2, etc. so I can just multiple-select and configure entire groups as GPIO_Outputs at once? Pins will show up in the GPIO Mode and Configuration table, but only after they are configured, not before. I can't easily just work my way around the package in Pinout view because the pins are never physically in alphabetical order, so that would involve a lot of hunting for the right p

Hello,With CubeMX V6.8 (I did not check with latest update), there is a bug in the USART clock source selection, for chip STM32L451VETWhen selecting SYSCLK for USART2 or USART3 (did not check with UART4), in the function HAL_UART_MspInit() the clock is init with :PeriphClkInit.Usart2ClockSelection = RCC_USART1CLKSOURCE_SYSCLK;instead of PeriphClkInit.Usart2ClockSelection = RCC_USART2CLKSOURCE_SYSCLK;That results in an incorrect initialisation !I don't know if it is related to the fact that in my project USART1 is also clocked by RCC_USART1CLKSOURCE_SYSCLKAurelien 

Hey there, at the moment I am stuck with the following problem: I need to trigger a SPI DMA Transfer precisely at each Timer overflow. NVIC Timer interrupts are not an option, because the jitter is way too high when I have to jump into code each time (I managed to trigger SPI-DMA transfer using the Timers NVIC global interrupt, but as I said, jitter is way too high). So now I am looking for a solution that involves the Cube MX, I want to configure the Timer in a way so that it directly triggers the DMA of the SPI? Or is there anything I can once declare in code that will do the job for me? In the end the solution should work without the CPU at all. I am using a NUCLEO-F446RE Board here, running at 180MHz. If someone has a quick solution (In Cube MX or Code, doesn’t matter as long as it works) I would be very thankful!Greetings Julius

Hi, I ran into a bug a while back where some ADC reads I had set up weren't working. In the course of debugging I found that the ADCs only worked after I changed the order in which some automatically generated startup functions were called in order to initialize the DMA controller before the ADCs. However, whenever I make changes to my .ioc and generate code it regenerates these startup functions in the wrong order. Why is this happening and how do I fix it?This is the incorrect order they are generated in:This is the order I have to change it to for the ADCs to work: 

I am trying to follow the "Getting started with X-CUBE-AI Expansion Package for Artificial Intelligence (AI)" document (User Manual UM2526), but I cannot validate the model on target.  Note that I'm using the STM32F746-DISCO instead of the recommended NUCLEO-F746ZG, but that's a minor difference.I can sucessfully validate the model on desktop (using random numbers and real data), but get an error when trying to validate on target using the "automatic compilation and download" option.CubeMX reports "Automatic build and run failed".Consulting the STM32CubeMX.log file I see the following error:2023-09-19 11:57:49,034 [ERROR] STM32CubeIDEBuilder:207 - !MESSAGE The project description file (.project) for 'mxAI1803873821400' is missing.

Hi All,I am new on STM32 and want to use printf on UART.I could run the printf on uart in the example folder.But couldnt find how does it work, actually couldnt find any comment in it about enabling printf on uart.I am useing STM32CubeMx and want to enable printf on its projects.I have tried some suggestion like adding following function that didnt work:void __io_putchar(uint8_t ch) { /** * \brief __io_putchar - A routine to transmit a single character out the serial port * \return void * \param[in] ch - uint8_t the character to transmit * \author andreichichak * \date Oct 16, 2015 * \details This routine assumes that we will be using UART2. A timeout value of 1ms (4th parameter) * gives a retry if the transmit buffer is full when back to back characters are transmitted, * avoiding dropping characters. */ HAL_UART_Transmit(&huart2, &ch, 1, 1);}Could someone help me on this issue? I am using NUCLEO-L011K4 board.Mostafa

Hi, I'm getting "ai_platform.h" file missing when doing "analyze" under the X-CUBE-AI section.I was following the steps from a contest, I have followed the same steps on a different desktop computer and I didn't have this issue on that system. I don't know why I'm getting this error on my personal computer. For the same ".onnx" file, I'm getting this error on my PC, and the output from analyze shows the size as ~45KB, whereas, the output on the other system (on which I didn't get this error) shows size of ~22KB. Please help me out.

Hallo, according to RM0433 6.4.1 "System supply startup" at point 5. "The software shall then initialize the system including supply configurationprogramming in PWR control register 3 (PWR_CR3). Once the supply configurationhas been configured, the ACTVOSRDY bit in PWR control status register 1 (PWR_CSR1) shall be checked to guarantee valid voltage levels" How should I understand it? Should the software always wait for ACTVOSRDY bit or should it only if PWR_CR3 is modified? Early start-up in Reset_Handler routine delivered by Cube-MX in /Startup/startup_stm32h7xx.s writes already to SRAM without checking the ACTVOSRDY bit. Quite late initialization in Cube-MX inside SystemClock_Config() does wait for ACTVOSRDY bit with help of: " while(!__HAL_PWR_GET_FLAG(PWR_FLAG_VOSRDY)) {} " but there are no writes to PWR_CSR1 at this place. Moreover, two lines befere there is SRAM access what should not work if exactly ACTVOSRDY is not set as stated in RM0433 in 6.4.1.5.a):"As long as ACTVOSRDY ind

Hello. I examined similar questions and answers. Since I'm a newbie, I couldn't find an answer to my problem.In the documentation of the STM32F756ZG development board, it is said that up to 24 channels of ADC measurements can be usable with 3 ADCs. When I want to assign pins in the CubeIDE, warning says that some pins cannot be used due to conflict.There are 2 different conflicts for ADC1, and only one for ADC3. I don't need to use ETH, but even if I set to ETH "disabled", the conflict does not disappear.I wonder if I can make 24 measurements with other available pins. Is it possible?Or does the dev card not allow using all the capabilities of the MCU? 

Hello,I am using Cube32MX for STM32H743bi IO multiplexing. first i added USB HS phy ULPI interface then see FDCAN2 not allowed in the tool and error message says it is in conflict with USB ULPI. However i manually checked there were certain pins for CAN2 classic and even FD available.I want to know whether it s some bug or there is some internal MCU sharing between these two that i am unaware of. Else several options are available for FDCAN2 after consuming USB ULPI.thnx

HelloIn glass LCD display configuration (for STM32L152RB in my case), for static display, in Cube we can see segment numbers SEG[0-31]. Meanwhile, SEG[31:28] are double numbered, also to SEG[43:40]. To use [31:28] designators there must be MUX_SEG bit in LCD_CR set.After code generation MUX_SEG is still disabled (0). I found the line in MX_LCD_Init function: hlcd.Init.MuxSegment = LCD_MUXSEGMENT_DISABLE;And i can't find proper setting in Cube to enable this MUX, i has to do it manually after code generation.This problem is misleading, because segments 31-28 are located in ROM[0] register, 43-40 in ROM[1] register. Cube shows numbers 31-28, we try to write ROM[0] register, what is not working, because this segments has numbers 43-30 and we should write other register (ROM[1]). And this is because of wrong MUX_SEG bit settings.Could you check this somehow?

I'm going to use CubeMX, is there a way to measure the voltage input through STM32F401CCU6 and ST-LINK? I'd like to know an example code or method if there is

I can't get my board to detect the WiFi chip over SDIO. I configured my boot SD card with a custom Linux install and everything is working except WiFi. It seems the WiFi chip is not recognized at all over the SDIO bus.  dir listing of /sys/bus/sdio/devices shows nothing, so the kernel isn't even detecting the chip. I tried using STM32CubeMX to generate a device tree, but this didn't work, and in fact the resulting dts file has references to headers that don't even exist like stm32mp15xf.dtsi. However, the OpenSTLinux that shipped with the board works, and the WiFi chip is seen by the kernel. I have configured everything properly with my kernel config, so I'm not sure where the problem is. I suspect it is with the device tree, but as I mentioned I can't generate a new one due to the missing headers. What should I do?
