I created a project in TouchGFX Designer and then I opened the project in CubeMX. It compiles successfully. But then I want to add UART function to my project. So I go to CubeMX and add UART function but when compiling it gives an error because the stm32h7xx_hal_uart.c and stm32h7xx_hal_uart_ex.c files were not added to Drivers\STM32H7xx_HAL_Driver folder. So I had to manually import them and it compiles fine.CubeMX should have a functionality to automatically add the corresponding files for each functionality.Now I have added FreeRTOS functionality and it's giving me the same type of error message, except I do not know what files to add since I am not too familiar with RTOS.The error message is so long that I had to take 2 separate screenshots, I hope you guys can read it and help me out.I suspect the problem have to do with missing files for FreeRTOS.

According to AN4144, page 14/28, the coefficient 'ke' is measured by turning the stepper and measure the phase voltage with a oscilloscope. For the coefficient 'ke' in V/Hz, which voltage normation should be used:Peak-to Peak, Peak or RMS?.

Hi, I have an application where the device must respond to another device as a part of UART communication @ 1 sec. However, at the same time to log 200 bytes of data upon update of a variable, I need to log it into Flash at Sector 11 of STM32F205RGYX_FLASH MCU so reprogramming Flash takes 1-2 sec of blocking erase cycle as stated in the datasheet, and then by it missed to respond to messages from another device also observed timeout at another end. ​Can we have any mechanism that reduces the erase cycle time for Sector 11 or any optimized way out to manage communication and reprogramming flash simultaneously?Thanks,

Hello there, STM32 community!I am new to the STM32 family and I am currently working on a project to read and write Mifare Classic and Desfire tags. For this, I am using an STM32G071-NUCLEO64 microcontroller and a X-NUCLEO-NFC05A1 (ST25R3911B) board connected via SPI. I have been trying to establish the SPI connection between the two devices and send/receive data, but so far, I have not been successful.Initially, I tried to use the SPI example provided in STM32CubeIDE, but I was not able to receive data correctly. Then, I followed a post on the ST community website to use the RFAL/NDEF libraries for my project. However, the post was for the 32f070RB board, and I had to make some modifications to make it work with my hardware.Unfortunately, after copying the RFAL and NDEF libraries into my project, modifying the platform.h file, and adding the necessary modules, I am still unable to get it working. The error I am receiving is:#define ERR_HW_MISMATCH ((ReturnCode)36U) /*!< expected hw

I have ported the NxWebServer example from the STM32H735-DK project over to the STM32H743i-eval. All the bugs seem to be worked out and connection is being made. I can see get requests coming in to the call back but after the second or third file for the main webpage the callbacks stop. I have tried slowing the SDMMC clock, Disabling Cache, to no avail. I have tried using the debugger to pause the code when the callbacks stop and the the code is always in the RTOS idle state with all the tasks either suspended or completed with the exception of the remaining sleeping thread that checks for connection status once every 10 seconds. On occation I will get the whole web page but that is very rare. Not sure where else to look.

Hi,I'm having some trouble with trying to correct the RTC drift on a STM32F439NIHx. I've enabled the REF_IN and provided a 50Hz signal on the pin, but the RTC still drifts by around 1s per day.I've also tested that the 50Hz signal is correctly received by changing the pin to an external interrupt and correctly generated 50 interrupts per seconds.Am I missing something or doing something wrong in the setup:Enabling the RTC and the ref in : RTC_HandleTypeDef hrtc = RTC_HandleTypeDef(); hrtc.Instance = RTC; hrtc.Init.HourFormat = RTC_HOURFORMAT_24; hrtc.Init.AsynchPrediv = RTC_ASYNCH_PREDIV; hrtc.Init.SynchPrediv = RTC_SYNCH_PREDIV; hrtc.Init.OutPut = RTC_OUTPUT_DISABLE; hrtc.Init.OutPutPolarity = RTC_OUTPUT_POLARITY_HIGH; hrtc.Init.OutPutType = RTC_OUTPUT_TYPE_OPENDRAIN;   if (HAL_RTC_Init(hrtc) != HAL_OK) { Error_Handler(); } if (HAL_RTCEx_EnableBypassShadow(hrtc) != HAL_OK) { Error_Handler(); }   if (HAL_RTCEx_SetRefClock(hrtc) != HAL_OK) { Error_Handler(

Hello,I’m using an ST MP1 Development Kit STM32MP157C-DK2 to develop and deploy projects involving Machine Learning on an SoC.I need to perform some pre-processing operations on data coming from different sensors and to do so I have at my disposal Python scripts with dependencies from libraries like NumPy, Pandas, SciPy, and Librosa.While the first ones can be easily resolved by installing them via apt, (python3-numpy and python3-pandas), I’m encountering difficulties with the other ones (scipy and librosa), which are not available on ST repositories.I tried installing them via pip3, but it requires a compiler to build both libraries and dependencies from scratch, and the current Linux image I’m using doesn’t include it.Do you have any ideas on how to proceed, to help me?Thank you,Andrea.

Hi all, I am working in uart2 which is connected to the usb port in nucleo -g431rb but I want to communicate not through usb but through PA2 and PA3 pins assigned to uart2 by default. Tx line work properly but Rx not. There is a good signal on PA3 input (I checked with oscilloscope) but MCU is not receiving data. I thought there was some collision with usb virtual port so I unsoldered solder bridges SB1 and SB12 - doesn't work. Rx uart2 works if I send data to usb port and not to PA3. Does anyone have any idea?

I have a characteristic1 as a write and I want to add a second characteristic as a read, but when I add this second I can't fint the device with the App?

I am currently working on a project to develop a zigbee module using the "STM32WB30CEU5A" MCU.I currently have "Zigbee" enabled with "STM32_WPAN" middleware via "STM32CubeIDE".I have several questions about it.1. In the UM2550 documentation, I am looking at section 4.2.4 "Installing and running the STM32CubeUpdater program". Here it says to install "STM32CubeUpdater", but I can't find this file. Has this been replaced by "STM32_Programmer_CLI"?2. if I buy the STM32WB30CE chip, does it come with firmware on the coprocessor by default or do I have to write the firmware.3. i am trying to build a module to replace the Digi Xbee S2C (IEEE 802.15.4 Function Set). Is there an example that I can refer to for this?4. can I read the memory of the coprocessor (Cortex M0) in STM32Cube Programmer ?Translated with DeepL

HiI would like to use STM32WB5MMG-DK.1) I tried to program 1.15 software packages for stack-ble + FUS + SAFEBOOT.The stack ble file size is 149KB, according to the release note it suppose to be programmed at address 0x080C5000 (or 0x080CE000).The FUS is suppose to be programmed at 0x080EC000 and the safeboot at 0x080F0000,but the stack-ble is so big (149KB) so its end is on 0x080F3000.How can I have all of them ?2) During my tries I erased all the sections between 0x080C5000-0x080F3000.Now, any combination of stack/FUS I tried, I don't have ADVERTISE (the code does not get to ADV_Request - but there are RX_IPCC interrupts)Is there something important that being erased ?Thanks

Hi,Can you tell me if STiD135 is EOL for now?Is there any alternative from ST?Thanks,Christie

I have a stm32f429 discovery board, can I use its 3V/5V pin as power supply?Image below is from mb1705c, I'm not sure the meaning of "EXT_5V, Input only".I would appreciate it if you could answer my question.

i am trying to measure the power consumption of the MCU in my custom board with different sleep modes, while measuring the stop2 mode i am getting consumption of 110 uA in the datasheet its showing of 2 uA ,even for shutdown and standby mode also its consuming that current.in sleep and active mode am getting proper value as mention in the data sheet.to get into stop2 mode am using,while (1){/* USER CODE END WHILE *//* USER CODE BEGIN 3 */ HAL_Delay(1000); HAL_SuspendTick(); HAL_PWREx_EnterSTOP2Mode(PWR_SLEEPENTRY_WFI); HAL_ResumeTick();}/* USER CODE END 3 *apart from this step do i need to do anything extra for enabling the stop2 mode.(am using lpm01a ST power measurement module.)

I'm building a project around the B-G431B-ESC1 board, that claims to support hall sensored 6-step control, but in motor bench there are no example files for this (only sensorless electric speed control files). I know you are supposed to generate files in motor bench and then set six step control method in CubeMX. But when I do that, I get bunch of errors in CubeIDE that I'm missing many necessary library files. When I link them in project options for compiler files from different project (that is FOC and does have them), I get the same errors. When I go back to Motor Control and update the same project (which theoretically should add those needed libraries) it rewrites the code and sets the control method to FOC (like it would ignore anything you'd set inside CubeMX). So my question is how to set up six step control?I've spent enormous amount of time trying to resolve this, but to no avail.
