STM32CubeMX (MCUs)

I’m trying to understand the peripheral current consumption figures generated by the PCC tool in CubeMX for my STM32U031 based project but can’t correlate the generated numbers with the values given in Table 43 of the datasheet, so I’m wondering which is likely to be correct, the PCC values or datasheet values?I’m also struggling to understand what the names used in the PCC ‘Peripheral Selection’ tab tick-boxes refer to; e.g. TIM1 vs TIM1/SYS, PWR/TIM2,  ADC1/SYS vs ADC1 CLK_KER_SYS etc etc, as there’s no help in the tool, or guidance in the UM1718, so any help here would be much appreciated!

Hi @STTwo-32  & Community, This issue was reported a long time ago but I'm seeing something similar again now. In my case it's the definition HAL_UART_MODE_ENABLED for my STM32H755 project, this define being put into stm32h7xx_conf.h after each code re-generation. My project began as one targeting the H755 Nucleo and at that point there was not problem. The problem arose after migrating to my custom H755 PCB, at which point I removed the Nucleo BSP stuff in MX (CubeIDE MX perspective); I also removed some other unwanted things such as Ethernet support (& LWIP) I have no UART/USART in my project and can't think of any reason why the UART definition should be getting into my HAL config. Viewing HAL modules in the MX Project settings does not show any peripherals other than those I'm expecting. My .ioc is attached in case it's helpful. Thanks Edi

Hello,  I'm learning about the STM32N6 LR and XIP examples and want to get hands-on with them. I've already set OTP124 to 0x8000.   If SYSB is configured to 400MHz, the number of memory data lines must be set to 1 line and disable "X_ICACHE_Init()" for the app to function.

This situation arose when working with the Nucleo-G0B1RE board and Cube Version: 1.18.1.It was desired to do per-byte reception over UART channel 5 on PD2/3 with interrupts.  The VAST majority of articles discussing this process state to use the HAL_UART_RxCpltCallback() function to read the byte from the UART buffer, since this function gets called by the ISR chain on UART interrupt.  However, these same articles also frequently fail to mention the following:1) The HAL_UART_RxCpltCallback won't get called unless it gets registered first.  This can be done with the HAL_UART_RegisterCallback() function...2) ...BUT, even if you register functions in this manner, they won't be used unless enabled by internal configuration files. To do that, you have to pull up the IOC file and go to the Project Manager section.  Go to the "Advanced Settings" and you will see that you h

Bug Description:When regenerating a CubeMX Project with the STM32CubeIDE Toolchain selected, CubeMX will change the ".cproject" file and add a "./Startup/" directory to the source locations of the project if the following conditions are present:1. In the root directory of the project (where the .ioc file is located) you need to have a directory with a name that is alphabetically closer to 'A' than the "./Core/" Directory. For example "./Application/"2. In this directory there needs to be a "main.c" file, which would be created by the user. This will cause CubeIDE to output a warning message on each build, stating that "./Startup/" could not be found. If the directory name comes after "Core" alphabetically everything is working like expected and no "Startup" directory is added as a source location to the project configuration. Version:This behaviour

Hello everyone,I'm new to STM32 and currently working on a USB CDC (Virtual COM Port) project using STM32CubeMX with the following setup:MCUs/Boards: STM32F103C8T6 and Nucleo-F334R8Toolchain / IDE: MDK-ARM (Keil µVision)STM32CubeMX versions tested: 6.14.1 and 6.12.1I configured the USB peripheral in Device Only mode and enabled the Communication Device Class (CDC) in the USB Device middleware settings. I also configured the required USB pins (PA11 as USB_DM and PA12 as USB_DP) and set the USB clock source properly to ensure 48 MHz operation.However, after generating the project, several key USB middleware source files are missing, such as:usbd_core.cusbd_ctlreq.cusbd_ioreq.cusbd_cdc.c(and sometimes also usbd_cdc_if.c)

In HAL_DCMI_Init() of stm32f4xx_hal_dcmi.c, HAL_DCMI_MspInit() gets called twice.  The 2nd call should be deleted from the source.  See lines 216 and 218.

Hi,I use STM32CubeMX v6.13.0 to generate a CMake project for STM32U5 devices. While code generation the process aborts with following error message:"The Code is successfully generated under: /home/user/projects/stm32u5_firmware Project language : C but CMakeproject generation have a problem." After looking in the generated CMake files, I spot various template artifacts:  cmake_minimum_required(VERSION 3.22) project(stm32cubemx) add_library(stm32cubemx INTERFACE) {{sr:Enable_CMake_lanuages}} target_compile_definitions(stm32cubemx INTERFACE{{sr:symbols_c_SYMB}} $<$<CONFIG:Debug>:DEBUG> ) target_include_directories(stm32cubemx INTERFACE{{sr:include_c_DIRS}} ) target_sources(stm32cubemx INTERFACE{{sr:sources_SRCS}} ) target_link_directories(stm32cubemx INTERFACE{{sr:link_DIRS}} ) target_link_libraries(stm32cube

Title edited for length - please keep titles short, but descriptive.Original title: "SPI callback interrupt does not work for SPI, but works if I switch to other SPI with identical settings, same for timers and other peripherals"Hello,There I have problem with callbacks, not only with SPI, but at this moment trying to solve there, I use SPI5 for communicate with sensor, worked well until I changed some completely unrelated settings elsewhere in cubeMX, after code generation I found what I do not getting data from sensor, in my code SPI DMA transfer was initiated by timer callback, timer simply calls HAL_SPI_Receive_DMA function at specified intervals, I noticed what tim

Translated content. 我在cubemx中同时使能usart1和usb发现有个警告 I enabled usart1 and usb in cubemx and found a warning usart1的流控被usb的dp和dm复用，但是实际上我是没有开流控的 The flow control of usart1 is multiplexed by dp and dm of usb, but I actually didn't turn on the flow control

Can I use Nexus as proxy server for STM32CubeIDE & STM32CubeMX?What is URL of ST repository?Any experience of proxy server is welcome, thanks

When you change  for example the clock in .ioc (like from 48 MHz to 20 MHz) and even change it back to 48 MHz, your display stops working properly (colors not showing). TFT st7789v display and stm32h753vit6 microcontroller please solve my issue.

I'm using the STM32F405RGT6 board in a controller project. I wanted to use PA0 as PWM and PA1 as RX. For some reason, when configuring the .ioc, even though I configure UART4 as receiver only, it doesn't allow me to use PA0 as PWM. Is there any other way to configure this in the code?

I don't see the wrapper listed in the package for H5 although its listed in this documenten.stm32h5-cube-firmware.pdfwhere can I get it? Is it possible to download and add the package to STM32CubeMX?

We are having a similar issue as this person here:https://community.st.com/t5/stm32cubemx-mcus/why-does-the-ioc-file-show-warnings-on-disabled-peripherals/m-p/144500/highlight/true#M5600One of the responses was that this is just a warning message and is okay.  But I think this is causing us to have an issue with using a CICD pipeline to handle project generation. When I use a build script with project generate I would expect the whole process to be done without interacting with the GUI but an empty warning message actually comes up for me to click 'yes' to before it will go any further.  I tried an .ioc file that I found online to test to see if it would also generate this error and it does not.   I am hoping ther

When I generate a new project in CubeMx 5.3.0 for the STM32H745I-DISCO board for IAR toolchain, I get the following code:HAL_PWREx_ConfigSupply(PWR_LDO_SUPPLY);The example projects in CubeH7 package use this code instead:HAL_PWREx_ConfigSupply(PWR_DIRECT_SMPS_SUPPLY);With the code generated by CubeMx, when I unplug the USB cable (which supplies power to the board) from the STLK port, plugging it back in causes the code not to run.With the code from the examples, the code runs ok.I believe the code generated by CubeMx misconfigures the FW for the STM32H745I-DISCO board.Anyone else have this issue?

Hello,I am experiencing the following issue and would appreciate your help in resolving it:When I create a new STM32 project for STM32G474CEU6 in STM32CubeIDE, main.c and other source files are not generated.The .ioc file loads correctly and the GUI opens as expected, but a message saying “Code generation could not be done..” appears, and only the BSD_License.ftl file is generated.When I press Alt+K to regenerate the code, only two files — common.ftl and mw_common.ftl — are added, and no error messages are shown.In the Problems tab of the IDE, a warning appears: “Project '*' has no explicit encoding set**”, but this can be resolved by pressing Ctrl+1. However, even after fixing this and regenerating the code, nothing changes.Under STWindow > Preferences > STM32Cube > Firmware Updater > Check Conn

I have set HAL_IncTick timer (tim6) to not interfere with systick when using thread and RTOS, the new callback was created by cubeMX and I got error about second declaration, I moved my timers settings to newly created callback, later I decided to change to tim18, after code upload I found what some functions do not work like expected, by debugging I found what everything what was in this callback is gone and there is newly created fresh callback just with newly created tim18 settings, everything else is gone ! CubeMX do not checks previously created callback by cubeMX and just deletes it !

Hello,I'm trying to run a ML model (miniresnet from modelzoo) to a NUCLEO-N627X0-Q starting from STM32CubeMX (initialization of device, model & code generation). Everything is OK when i select STM32Cube.AI MCU runtime, the model is created and runs smoothly, however, when i select STM32Cube.AI Neural-ART runtime (with n6-noextmem profile since i have various problems with external flash and the model is small enough to fit in SRAM) the code is generated fine, but an extra .raw file ([modelname]_atonbuf.AXISRAM5.raw) is created.I noticed the the compiled .bin file  (In STM32CubeIDE) is rather small (~62Kb) so i am pretty confident that it does not contain the full model (~122kb). I suspect that somehow i have to load this raw file to memory for the NPU to read.When i run the model through NPU the output is constantly zero (uninitialized or zeroed weights maybe?).I am using the nucleo in n DEV_BOOT Mode

I would like to filter available products by the following specific peripherals, but those types of filters do not seem to be available.PSSIDMAMUXMDMALPDMAGPDMAHPDMASDRAM support andMinimum #of pins sized package to actually support 1 or 2+ SDRAM chips at 16, 24, or 32 bit Did I miss something or are there maybe future plans to support that kind of filtering ?Are there alternative papers/docs listing the products (and which are kept up to date) ? 

Sometimes CubeMX do not generate code correctly, not always, but sometimes in initialization codes generated by CubeMX is missing declarations in peripheral settings for DMA with error "undeclared",  currently I got this problem after clocks configurations and code regeneration, there is missing TRANSFERALLOCATEDPORTSRC_GPDMACH1, TRANSFERALLOCATEDPORTSRC_GPDMACH2, TRANSFERALLOCATEDPORTSRC_GPDMACH3.... declarations:

Hi , allI am currently working on a project using the STSPIN32G4 together with the STM32 Motor Control SDK (MCSDK). I would like to add the internal Temperature Sensor to monitor the MCU temperature.In STM32CubeMX, I have already enabled both the Temperature Sensor and VREFINT channels on ADC1, and generated the initialization code. Then, I configured the Temperature Sensor and VREFINT using the RDivider_Handle_t structure, and used the related APIs to read the ADC values.However, no matter whether I read the Temperature Sensor or VREFINT, the ADC values are always very close to zero, as if the sampling is not working correctly or is misconfigured.My questions are:Within the MCSDK framework, is it possible to directly use RDivider_Handle_t to read the Temperature Sensor and VREFINT channels?If not, what is the correct way to configure and ac

I cant get faster SPI performance, in every SPI DMA request mcu receiving 164 bytes of data, the maximum request rate what I got is about 1KHz, total number of bytes is only ~ 164 * 1000 = 164KB, I need to reach 8KHz rate, MCU and other clocks is set to almost maximum values, on STM32H7 MCU with many other tasks I reached without any problems 12KHz rate, with N6 I cant get event near of required transfer speed in any configurations, If I rising request rate I getting SPI busy error, where can be the problem ? What peripherals or other settings is responsible for SPI transfer and interfere there ? I can attach .IOC file or more info.In my setup SPI requests is controlled by HAL_TIM_PeriodElapsedCallback(), sometimes I need to stop requests in case when synchronization is lost, timer fires function for next SPI DMA transfer and in case of error (in my case I getting SPI busy error) the timer for request is stopped, timer fires simple function:void nextPacket(){
