Hello, I have downloaded a library containing two files: the .h file and the .c  file: I used drag and drop and dropped the folder into the driver folder of my project. I selected them to be a reference and a relative path. Then I selected the compiler include path:  and the linker pathThe IDE is showing the resource correctly linked to the project: when I build the project I still get the error message: What is wrong with my approach?How do I set the paths correctly?As a suggestion: I have found many users struggling with this. I would like to recommend a dialog for dropping a folder into the project with predefined links to the new folder.Regards Alexander 

Hi, i am trying to connect the nrf54L15 with the VL53L4CD sensor. I am having trouble with library and the code. Struggling with connecting the nrf54L15 to the sensor in the different libraries. Are you able to share the different register adresses for the VL53L4CD sensor? Do you have an examples using the nrf54L15 and or device tree with the VL53L4CD?

In instances where they don't answer the question, or where they answer it incorrectly, I have been reporting these. Should I keep doing so?Does the ST community have a stance on whether or not AI-generated reponses are allowed? Is that stance in the guidelines and if not, can we put it there?For example, clearly this is ChatGPT generated nonsense:Another one, same thread even.At first glance it seems like these answer the question, but they fall apart under inspection. These two are obvious, some are less so.

I am using output compare with TIM3 on a STM32H755 I am able to use Output Compare to generate a single pulse on pin PC7 using TIM3, Channel 2.I am using Active Level on Match.I call HAL_TIM_OC_Start(&htim3, TIM_CHANNEL_2) onceAfter 0.5s, it detects a match (which is good), and my pin drops and stays low (I have negative polarity set).However,  I can find no way to restart the process.I have tried resetting the timer calling HAL_TIM_OC_Stop(&htim3, TIM_CHANNEL_2) and HAL_TIM_OC_Start(&htim3, TIM_CHANNEL_2), but the pin remains low. I've even tried calling the initialisation code again. I assume I am missing something fundamental here? Settings: (see screen shot attached )Auto-reload preload: DisableMode: Active Level on MatchOutput Compare Preload: DisableCH Polarity: Low 

Hello everyone, I am a first-year university student. I am developing a GUI application on the STM32U585 using TouchGFX Designer and FreeRTOS, and I have encountered some issues. Due to my lack of experience, I would like to ask for your advice on how to solve these problems. Here is my GitHub repository for the code(https://github.com/weixuna/GPDMA_AMOLED_). Device information:MCU: STM32U585CIU6RTOS: FreeRTOSGUI: TouchGFXIDE: STM32CubeIDEGPDMA enabledThe display is AMOLED, and the MCU communicates with the screen via QSPI in OCTOSPI mode.Phenomenon:I added two buttons in TouchGFX Designer.When I swipe to switch to a page (Screen) with two buttons, the program sometimes crashes and enters a HardFault.The crash happens during or after the page transition animation.If I add transition animations such as Cover, Wipe, or Block, there will be screen corruption (garbled display).

Is there any information for the STM32H735-DK on how to configure the S70KL128 HyperRAM to work?Unfortunately, there's no source code for the binary demo from ST, so I'm forced to try to get the HyperRAM working somehow.And the forums only provide information about problems when trying to run it in memory-mapped mode.So far, I haven't been able to read or write a single byte because:- The access times, latency times, and the clock in the STM32H7 must be set correctly for the HyperRAM to be accessible at all.- The settings in the HyperRAM itself also need to be configured (DDR/DTR, drive strength, latency, burst length).When creating a new project with the default values ​​in the STM32CubeIDE for the evaluation board, adjust the octospi clock to 100MHz (PLL2R) and attempting to read the hyperram with the debugger, the only output is:Could not halt device (18)Failed to read all registers from targetTarget is not responding, retrying...Target is not responding, retrying...When importing p

I'm trying to move my project from CubeIDE to IAR 9.20.4For some reason I'm gettin Linker Error[Li006] duplicate definitions.With CubeIDE I'm able to compile and debug/download with no issue.I know the error is due to the fact I'm having variables on the .h files included in various .c files that are not set as external. The question is why CubeIDE ignore this issue and the IAR do not?

Hello,I'm trying to silently install Atollic TrueSTUDIO for STM32 v9.3.0 for use in a CI/CD pipeline.I'm launching the installer from a .bat file using the following command:Atollic_TrueSTUDIO_for_STM32_windows_x86_v9.3.0_20190212-0734.exe /S /D=C:\Tools\TrueSTUDIOWere:/S = Silent installation (commonly used with NSIS-based installers)/D= = Destination path for installationThe installation does not run in silent mode – the graphical installer still appears. There are no error messages, but also no indication that a background installation is taking place.Does the TrueSTUDIO installer support silent installation at all?Setup Details:TrueSTUDIO Version: 9.3.0 (Build 20190212-0734)Platform: Windows 11Installer Filename: Atollic_TrueSTUDIO_for_STM32_windows_x86_v9.3.0_20190212-0734.exeAny insights or suggestions would be greatly appreciated – thanks in advance!Martin  

Hi all ,I’m currently using the EVSPIN32G development board to run six-step trapezoidal commutation.I’m using Motor Pilot version V1.2.12 with the MC_6STEP GUI.In the ST Motor Control tutorial under '6-step - Optimization and troubleshooting of sensor-less firmware parameters,' I saw several phase voltage (BEMF U/V/W) waveforms. However, in Motor Pilot I can only find 'bus voltage' and 'bemf_ADC_conf'—I don’t see any options related to viewing BEMF U/V/W voltages directly. Could you please advise how I can access these waveforms, or if there’s an additional setting or tool needed to display them?Thanks.

Hello, I am trying to use SPI with the STM32H7A3RGT6 microcontroller to send and receive data. However, I am not sure if I have created my functions correctly, or if I have properly configured the registers to achieve full-duplex SPI functionality.

I'm using an STM32WB5MMGH6 and it's consuming too much current at Stop 2 Mode.The existing BLE connections are closed and advertising is stopped. All unnecessary peripherals, gpios and interrupts are disabled. The system clock is changed to MSI at 1MHz and Systick is disabled.In the current conditions, the system consumes about 1 mA while in Stop Mode 2.We tried using Shutdown Mode and got a consumption of about 100 uA which corresponds to the expected current bleed eliminating a hardware problem. Using Stop Mode 2 we expected about the same consumption.What's missing so that i can achieve a lower consumption?Here is the code snippet: GPIO_InitTypeDef GPIO_InitStruct = { 0 };// Configure the system clockRCC_OscInitTypeDef RCC_OscInitStruct = { 0 };RCC_ClkInitTypeDef RCC_ClkInitStruct = { 0 }; HAL_NVIC_DisableIRQ(ADC1_IRQn); // ADC INTHAL_NVIC_DisableIRQ(EXTI1_IRQn); // GAUGE_NINTHAL_NVIC_DisableIRQ(EXTI15_10_IRQn); // SENS_INT1HAL_NVIC_DisableIRQ(EXTI3_IRQn); // IMU_DRDY

Hi,While learning TouchGFX, I created a fairly extensive UI application using TouchGFX alone (i.e., without any custom code). I also have a separate, larger Vending Machine Controller project, where the rest of the system has already been coded. I now need to join them. 1) What is the best and most reliable way to integrate the TouchGFX project into the Vending Machine Controller project? Is there a detailed guide available for this process? 2) Is there a merge or export/import tool available, or should I simply copy the folders manually? 3) What steps should I take before and after merging them (such as checking or modifying settings in the TouchGFX project and/or the CubeIDE project)? Thank you

Hi all.We are evaluating the use of ST25R3911B on production line in order to communicate with our metering product which embeds STM32U5 and ST25DV.We'd like to customize STSW-ST25R001 firmware for ST25R3911B-DISCO board to our needs but the provided firmware project, part of which was clearly generated through CubeMX, targets the Keil toolchain and lacks the CubeMX .ioc project file, whereas we need to use the GCC toolchain embedded in CubeIDE.Can you provide the CubeMX .ioc project file to speedup our development as soon as possible?Thank you in advance.Best regards.

I'm working on developing product, for that I was going through the documents of AC/DC & DC/DC products for reference but, I'm not able to find any detailed documents. If you have any application notes or design documents regarding these products, it would be very helpful for me. If you know any contact mail IDs whom I can reach out, please provide.

When generating code that uses the CMSIS OS V2, it appears that a template directory gets included in the generated code. causing massive linker errors. The offending directory is Drivers/CMSIS/Device/ST/DEM32WL3X/Source/Templates. Removing it gets rid of the errors.While we are at it, the LICENSE.txt file in the same directory is spelled incorrectly, it should be LICENCE.txt, as it is not a verb.  

Hello there,I am currently working with the STEVAL-PROTEUS1 evaluation board.To supply power, I have connected the board to my computer via micro USB (alternatively, a battery could have been used, but it should not make a difference).For data acquisition through USB using NanoEdge Studio, I established the STLINK-V3MINIE connection as shown in the attached picture.Although NanoEdge Studio detects "STMicroelectronics" on COM7, I am unable to receive any data.Additionally, I have noticed that the STEVAL-PROTEUS1 board itself does not appear separately in the Windows Device Manager. Only the STLINK-V3MINIE appears, even though both the STEVAL-PROTEUS1 micro USB and the STLINK-V3MINIE USB are connected to the PC simultaneously.Is this behavior normal, or could it indicate an issue with the setup?For reference, I recently flashed the firmware file Proteus_HS_Datalog_FUOTA_reference.bin.Firmware updates via STLINK-V3MINIE complete successfully, but NanoEdge Studio still fails to acquire any

Hi, Is it possible to obtain more information regarding the typical performance characteristics of MEMS accelerometers? We are currently evaluating the LSM6DSO32 sensor, and the datasheet is mostly just +/- in terms of accuracy. We would like to see the performance graphs over a range of frequency / temperature / etc.  

Dear Community, I am currently facing an issue related to locking an NFC tag after writing data to it. By "locking," I mean making the tag's data read-only, so that once the data is written, it cannot be modified or overwritten. The contents of the tag should be permanently locked after the initial write. This functionality is intended for use in a fintech application, where data integrity is crucial. Could you please guide me on how to implement this lock feature after writing to the tag? Thank you in advance for your support.My Write Function is working perfect private async void WriteDataToNfcCard(ICardReader reader, string data) { try { // Validate UPI link if (!data.StartsWith("upi://pay?")) { lblJustaSec.Invoke(new Action(() => { lblJustaSec.Text = "Input is not a valid UPI link."; AppendToTextConsole("Input is not a valid UPI link."); })); MessageBox.Show("Input is not a valid UPI link.", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); progressBar1.Visible =

Dear experts, I am facing an issue when measuring a pack of 14 batteries Fenix ARB-L18-2600. When fully charge 4.23 Volt, the BMS63EN return around 4.0x Volt. When the batteries reduce to 4.12 Volt, the BMS63EN return ~3.98 Volt. Could experts tell me where and how to modify or calibrate the BMS63EN Board?. (I used the Autodevkitstudio-2.4 with both SPC58EC - AEK_POW_BMS63EN_SOC_Estimation_14Cells_GUI application for discovery and SPC58EC - AEK_POW_BMS63EN_SOC_Estimation_Single application for discovery example to measure but they still return same measurement error). I am really appreciating for your help. Best regards, Tri Huynh.

Hi All,I have a system with 2 SPI masters and a single slave very similar to this post from 2014:https://community.st.com/t5/stm32-mcus-products/spi-multi-master-mode-with-stm32f050/td-p/502107What I would like to do is to temporarily isolate the STM32 SPI master from the bus when the second SPI master is in control.  I don't want to re-init the STM32 SPI between Master and Slave as it might affect the DMA setup so I was thinking of simply changing the CLK and MOSI lines temporarily to input, will this work? Something like this: Enable Master: LL_GPIO_SetPinMode(GPIOA, LL_GPIO_PIN_5, LL_GPIO_MODE_ALTERNATE); LL_GPIO_SetPinMode(GPIOA, LL_GPIO_PIN_7, LL_GPIO_MODE_ALTERNATE);  Isolate Master: LL_GPIO_SetPinMode(GPIOA, LL_GPIO_PIN_5, LL_GPIO_MODE_INPUT); LL_GPIO_SetPinMode(GPIOA, LL_GPIO_PIN_7, LL_GPIO_MODE_INPUT); Thanks,Hans.
