Solved

I’ve noticed that when replying to a post that I had written a lot of text and added images. I expanded (red circle) the text area (blue area) to see everything. I needed to copy some text from the OP so I used the scroll bar (red rectangle) to view the first post.But as you can see in green, it’s just a small area that can be seen and that is all that is seen during scrolling. The edit textbox stays in place and doesn’t scroll. If i expand the edit textbox even further, all of the green area is totally out of frame.  

Hello everyone,Has anyone successfully used the "ST25R95 EMI FILTER CALCULATION.xlsm" spreadsheet?I'm currently trying to use it for tuning the matching network of an ST25R95 design, but it doesn't seem to work correctly on my side. As soon as I modify any parameter or use the reset function, all the graphs disappear and I can no longer obtain any meaningful results.At the moment, this tool would be very useful for optimizing the matching network, and without it I'm having some difficulties proceeding with the tuning process.Has anyone experienced the same issue? Is there a specific Excel version, macro setting, or workaround required to make the spreadsheet work properly?Any suggestions, advice, or alternative methods for tuning the matching network would be greatly appreciated.Thank you in advance for your help.Marco

I wanna implement Master and Slave ethercat protocol on stm32h7 series. Is there any examples available on subject?. Where should i start. Any resources?

HiI am implemented flash write protect on STM32U5 using option byte register FLASH_WRP2AR.Following these steps to write protect page 0x4C and 0x4D page in Bank 2- Unlock flash - Unlock Flash option register(FLASH_OPTR)- Unlock flash page by setting UNLOCK bit(31) in FLASH_WRP2AR- Write WRP2A_PSTRT[6:0] of  FLASH_WRP2AR with value 0x4C- Write WRP2A_PEND[[6:0] of  FLASH_WRP2AR with value 0x4D- Lock flash page by clearing UNLOCK bit(31) in FLASH_WRP2AR - Initiate option byte programming by setting OPTSTRT bit FLASH_NSCR register - Wait for flash operation to complete - Lock FLASH_OPTR register - Lock FlashThis sequence works some times , however most of the time  after option byte programming FLASH_WRP2AR value resets to following value and write protect is disabled. - WRP2A_PSTRT[6:0]: 0x7F - WRP2A_PEND[[6:0]: 0x00OPTWERR bit sets in FLASH_NSSR indicating that invalid configuration, however configuration looks right.Regards,Hareesha 

I need to use embedded STM32H573 bootloader to update customer application using UART1 or uart3.I try to use AN2606, but no success. May you provide correct code to jump from application to the embedded bootloader for specific processor model: STM32H573, please?

Added dual-core to title - may be significant ...Hello.I've tried rename my project in the past, and this always generate a lot of errors due to the dependencies.Which is the properly way?I am working with STM32H755. Yes, dual-core.Thanks!

The Data Brief for the STEVAL-CAM-M0I adapter board references the FH12-24S-0.5SH(55), which is a 24-pin connector. However, the cable pinout appears to be the usual 22 pins. Is this a mistake in the Data Brief, or is there something I'm overlooking?Data brief - STEVAL-CAM-M0I - P-Board: Hardware MIPI CSI-2 kit for the evaluation and integration of promodules on embedded processing platforms

Hello group,I'm a humble hardware guy integrating the LSM6DSV16X into a robotic application.We are going to use it in control loops, between 3kHz and 5kHz sampling.Between the main mode and the OIS mode, there are tons of ODR to choose from.However, is there a way to make the ADC sample at EXACTLY 5kHz?? Like a triggered or synced ODR?Or do I have to set the ODR at 7.68kHz and read the latest value from the FIFO and deal with the small discontinuities?I see the Triggered-ODR section 6.6 in the datasheet. Does it means enabling this will sync the ADC with an external INT2 pulses? Does the new values appears in the FIFO after a defined short delay?Thanks!

Hello,I am evaluating IIS3DWBG1/IIS3DWBG1TR and AIS25BA/AIS25BATR for a data acquisition system where sensor data timestamps need to be aligned with GNSS time.I would like to ask whether these devices support any GNSS-related time synchronization interface or equivalent mechanism, such as GNSS/GPS 1PPS or PPS input, UTC/NMEA time reference input, PTP/IEEE1588 synchronization, external sync input, external reference clock input, FSYNC/CLKIN/EXTCLK, or any pin/register mechanism that can reset, latch, align, or discipline the internal timestamp counter using an external timing signal.Based on my review of the publicly available ST documentation and product pages, IIS3DWBG1/IIS3DWBG1TR appear to provide an internal timestamp counter and FIFO timestamp function, but I have not found any clearly documented pin, register, or configuration mechanism to align this timestamp to GNSS 1PPS/PPS or UTC time.For AIS25BA/AIS25BATR, the publicly available documentation shows TDM interface signals such

Hello, I'm trying to convert a project to vscode the first error I incurred to was this one: I'm trying to convert to cmake using the extension a project for the STM32U585OIYXQ, when I load the source folder and set the output folder then i push on convert and this is the output that I get :   [Error] [ide-project-convert]:Generating project...

I am using a stm32h562agi6 and configured fdcan2. It works!But then I wanted to create a zephyr os project and saw that there the fdcan2 is not available for stm32h562xx in general. I did some investigations and also the datasheet actually states that fdcan2 is not available (features and peripheral counts). I basically read everywhere that it has only one fdcan peripheral. I use PB5 and PB6 which are only listed for FDCAN2.  So what is true now? Is it because it’s a UFBGA169?

Hi everyone I have a bit trouble initializing the JPEG peripheral on the N6. See the stack trace:  I feel like this has something to do with the RIF? I don’t know, this chip is very new to me. If anyone can help me, it’d be greatly appreciated. Best regards

Device A is an Ethernet implementation based on the STM32F107VCT6 microcontroller and the LAN9303 Ethernet transceiver. It connects to a host computer via a Layer 3 switch, with Device A and the host computer assigned IP addresses in different network segments.Two batches of STM32F107VCT6 microcontrollers are currently deployed. With the Layer 3 switch properly configured, the following test results are observed:For the older batch of STM32F107VCT6 devices, the host computer can successfully ping Device A, regardless of whether the Layer 3 switch is a Huawei or TP-LINK model. For the newer batch of STM32F107VCT6 devices, the host computer cannot ping Device A when using a Huawei Layer 3 switch; however, ping communication is successful when using a TP-LINK Layer 3 switch.The above observations indicate a batch-specific anomaly in the network functionality of the STM32F107VCT6. What is the specific root cause of this issue?Upon verification, the defective STM32F107VCT6 units have lot co

Hi,I am working with an STM32H7 microcontroller and the EVB-LAN9252-SPI board from Microchip Technology.I would like to establish communication between the STM32H7 MCU and the LAN9252 over the SPI interface. Could you please provide guidance on the hardware interfacing, software setup, and initialization procedure required to bring up the communication?Additionally, please let me know the software packages, drivers, middleware, or example projects that would be needed for this implementation.

Hi everyone,I am developing a custom board using an STM32U5 and the LSM6DSV16BX. I am using MEMS Studio to train and configure the Machine Learning Core (MLC), but I noticed that the generated .h configuration file seems to set INT1_MLC1 bit at MLC_INT1 register by default.Even though I haven't explicitly set up physical pin routing in my project, the exported C array includes bank-switching logic that forces this configuration. I see the following sequence in my generated header:  { .type = MEMS_CONF_OP_TYPE_WRITE, .address = 0x01, .data = 0x80 }, // Switch to Embedded Bank // ... [other configs] ... { .type = MEMS_CONF_OP_TYPE_WRITE, .address = 0x0D, .data = 0x01 }, // MLC_INT1: Route MLC1 to INT1 // ... [other configs] ... { .type = MEMS_CONF_OP_TYPE_WRITE, .address = 0x01, .data = 0x00 }, // Return to Main Bank Because of this, INT1 pin is firing on MLC state changes. Since this is a custom design, I need strict control over my interrupt routing.My questions are:Can s

When will the NUCLEO-C5A3ZG  be available via distributors?The st.com site lists it as available(mass production), but none of the distributors has listed it at all. And the estore lists it as coming soon. Do you have any more concrete dates, will it be available anytime soon?   Best

The “Others: Hardware and Software” forum has over ten thousand entries. That is a lot. IMO, it would make sense to have a separate forum for the STM8; that would make it easier to browse STM8 ports, and declutter the “Others: Hardware and Software” forum. The only thing about STM8 that is still there in the new forums is the “STM8 MCUs” tag. And apparently most existing posts about the STM8 don’t even have that tag. 

Hello,I have provisioned two STEVAL-MKBXPRO Rev A boards using the FP-SNS-BLEMESH1 firmware and the ST BLE Mesh mobile application.My goal is to configure one board as a sensor node and the other as a relay/receiver node. Both nodes have been successfully provisioned and added to the same mesh network.However, I am unable to make them communicate correctly using only the ST BLE Mesh application. I cannot get sensor data to be transmitted from the sensor node to the receiver node.Could you please help me

Hello,  I’m having some problems with regression tool configuration for pedometer.I'm having some issues with the regression tool configuration for the pedometer. I’m using the STEVAL-MKI109D and STEVAL-MKI238A with MEMs Studio tool (FW: 2.10.2).First, I set up the sensor using 'Easy Configuration' and changed the Full Scale to ±4g, the Output Data Rate (ODR) to 25 Hz, enabled High-Performance mode, and set the bandwidth to ODR/2.Quick setup configurationFirst, I recorded and saved different walking types (slow, normal, and fast, with 20 steps each) using the 'Save to file' tab. This only saves the Accelerometer data.Next, I opened the Pedometer tab and ran the regression tool using these three files (fast_steps20.txt, normal_steps20.txt, and slow_steps20.txt). I selected the LIS2DUX12 sensor and tested it with the default settings for error type (Mean) and complexity level (50%). The generated results are in the attached zip file.After that, I went to the debug page to test the result

 I noticed the following in the recent post announcing STM32CubeIDE for Visual Studio Code 3.8.0:CLI tools: A new bundle manager is enabling VS Code to download required CLI tools. This replaces the all-in-one STM32CubeCLT package. ...Now that STM32CubeCLT is no longer required by the VSCode integration, what is the future of STM32CubeCLT?  In particular, will it continue to be updated and supported?

We are seeing a very odd data corruption issue which is highly repeatable, and appears to be related to a configuration setting which we haven't yet identified.In our system (running on an STM32H7S7), we're using the STiROT + OEMuROT secure bootloader to load our application. After a minute or two, the application causes a hard fault.The issue comes down to a POP instruction. I can see in the debugger that a value is being copied from the stack to a register, but one of the bits is flipped. Subsequent instructions do some indirection which ultimately causes the hard fault.It's always the same instruction in the same line of code. It always occurs within the first minute or two of execution.Using the debugger, we can see that the value in the stack (stored in DTCM) is correct. The error occurs when it's copied to the register. And although the error always occurs at the same address, it doesn't appear to be a fault with that location, as when I moved the stack to elsewhere in DTCM,
