Try to use STM32G0 LQFP32 MCU do accuracy frequency measurement, but there is no HSE crystal interface, so internal HSI RC will be for system clock, the accuracy of the system clock will affect the frequency, how accuracy is internal HSI RC clock

Hi,for my application I need to set RDP regression from my application code :1) Is it possible in RDP2 to provide OEM Key (for regression) from application code in order to restore JTAG access (and perform a regression whith a user intervention)2) Is it possible to do RDP 2 => RDP 1 from application code (using DBGMCU_DBG_AUTH_DEVICE or other way) ? if yes what is the correct process3) is it possible to go from RDP 1 to RDP 0 or RDP 0_5?for this part I try the following code without success (no error but no RDP Regression)  FLASH_OBProgramInitTypeDef obConfig = {0};  HAL_FLASH_Unlock();  HAL_FLASH_OB_Unlock();  obConfig.RDPKey1 = 0x11111111;  obConfig.RDPKey2 = 0x11111111;  obConfig.RDPKeyType = OB_RDP_KEY_OEM1;  obConfig.OptionType = OPTIONBYTE_RDPKEY;  HAL_FLASHEx_OBProgram(&obConfig);  obConfig.RDPLevel= OB_RDP_LEVEL_0_5;  obConfig.OptionType = OPTIONBYTE_RDP;  HAL_FLASHEx_OBProgram(&obConfig);  obConfig.RDPLeve

Hello, I'm able to connect the STM32CubeMonitor-UCPD with NUCLEO-G071RB and X-NUCLEO-SNK1M after following the instructions in AN5418. I only changed port 0 Sink PDO1 to 0x020641F4.I want to use the setup as a sink and always want to get the maximum power the source can deliver.But when I request a Power Profile, the Message gets rejected. Maybe someone could give me a hint what I'm doing wrong?Thank you and best regards

Good day I am currently trying to get a st25dv04k running on an nrf9160dk using i2c. At the moment i'm having trouble 'waking' up the slave as i'm not sure what address to send the startup condition to. Please assist if possible.Thank you

I'm trying to send udp data from stm to server. But when i observe in Wireshark, the protocol shown as ECHO, not UDP. What is the reason?

Hi,I use STM32CubeMX to configure a STM32H743 device. I enabled global DCMI interrupts.But I see no HAL functions to start the DCMI and enable specific interrupts.I hoped to find suitable functions in stm32h7xx_hal_dcmi.c. But there aren't.There is a HAL_DCMI_Stop() but not a start equivalent.There is a HAL_DCMI_Start_DMA() which is strange because I did not enable DMA in STM32CubeMX. (Well, I did first, but then I disabled it)I see the interrupt functions like HAL_DCMI_VsyncEventCallback() which I can overload, but I see no functions to enable each specific interrupt.What am I doing wrong?

Using STM32H735, Can I play any video clip?TouchGFX has video clip play example for STM32H735-DK EVB.But It is not working.

I want to disassemble the ADC function and BLE data transmission asynchronously.So, I want to program the microcontroller using multi-thread.When I coded BLE, It look already used multi-thread but I couldn't understand it exactly.Is there any example of this?

I'm developing a custom board with STM32WB55.Because there is some error during debugging, I'm trying to solve it.To check what is problem in the microcontroller, I tried Fault Analyzer in the STM32CubeProgrammer and the program found such an error below."MemManage fault detected in instruction located at 0x6414AA00"Here is the question.How can I understand what's this error and how can I fix it?

Hello,I'm working with blueVoice over sensorTile.I downloaded FP-SNS-ALLMEMS2 project version 2.1.0 and also project FP-SNS-ALLMEMS1 in version 4.2.0 and 4.1.0On Android side i'm using ST Ble Sensor app from Play StoreAll of them give me a very bad audio, with a cracking noise in background.I have good result only using a second SensorTile with preinstalled FP-SNS-ALLMEMS1 in version 3.1.0.Unfortunately I not able to find source project related to this version (3.1.0).Are they available in some way?Thanks to all and regards

Hello,I have a project working on the F303-re Nucleo board. I want to run it now on the F303-ze Nucleo board. Apparently virtual com port doesn't work the same on the ZE as it does on the RE. I can take a new RE board, copy the binary file to the RE board and the app starts communicating on the virtual comm port. I do the same thing on the ZE board and I get no virtual comm port communications. I assume I'm missing a jumper or solder bridge configuration that will allow the ZE to start virtual comm port communications. What am I missing?Thanks,Dave

HiRegarding Scan command.I never get ACI_GAP_PROC_COMPLETE_EVENT after 10 sec. (AN5270 says I should get one)I do get all the updates, but never the complete .Can you check if I need to terminate it myself?

Hi,May i know which pin on SPC57S-Eval kit board use for serial clock and serial data?I want to connect the gyroscope sensor to the board.

I ran stm32 with cubemx and iar to execute the project, but I have to remove the st-link line and execute itIf I take out the line, the project can't be executed, so how can I only connect the board and power to run the project?download active application -> download fileI tried it the above way, but it doesn't work when I turn it off and on

I am currently working on a STM32F767ZI-Nucleo board and a little security chip (microchip atecc508a), that is connected via i2c connection. For this chip is a library available CryptoAuthLib (https://github.com/MicrochipTech/cryptoauthlib), that I want to use in my project. I'm also using STM32CubeMX to generate my C-Files and Atollic TrueStudio to write my implementations.C programming language is relatively new to me, so I have no idea how to include my library folder to my project (either in cubemx or in trustudio?) to get it work.I think the include statement "#include "cryptoauthlib.h"should be in the main.cinclude section, but in a certain way I have to tell the IDE to use this library.I appreciate any help, thank you very much.

Hi.For accelerometer LIS3DHTR, the output signals INT1 and INT2, pins 11 and 9, they are both push-pull (CMOS) outputs? or one of them, or both, have open-drain configuration?For my projects it is better that both INT1 and INT2 be CMOS outputs.Regards,Jeferson Pehls.

There are several options. The chip I normally work on is this: STM32F469NI...In the quoted video, the author works with pa1 on stm32f407vgt6. What would be the equivalent on the stm32f469 disk kit?:

Hello, I'm working on a few designs that use the ST25R3916B. I've implemented the antenna match that incorporates 5 variable capacitors based on X-Nucleo-NFC08A1. In one reference design I see that you use the LXRW0YV201-059 but in a different reference design the LXRW0YV600-054 is used. Which is correct?

Hi there, I'm following all the steps described in Distribution-package to compile the yocto build for STM32MP157F-DK2 (stm32mp1). And at the beginning of the compilation (bitbake st-image-weston) I am getting the message : .....openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15/layers/meta-st/meta-st-openstlinux/recipes-st/images/st-image-resize-initrd.bb: ENABLE_PARTITIONS_IMAGE not enabled is it a problem? Did I miss something? Thanks Simone

I've been working with a LPS28DFWTR pressure sensor and noticed it's pretty sensitive to sunlight. As in, the pressure will climb significantly when the sun shines on it. Because the membrane appears to heat much faster than the temperature sensor it, the reported pressure isn't temperature compensated. This isn't really a problem but I'm curious what material is used to make the membrane?

Hello,I admit that I feel like I'm missing something obvious here, but I am using the STM32H7B3I-EVAL evaluation board and they have 0.05" pitch header pins for some of their connectors (CN5/CN6). I am trying to source a single position connector that can connect to their header pins (P/N: FTR-130-53-L-D-LC). I am looking for something similar to the image below, but 1.27mm (or 0.05") pitch and female. I want single-position so I can send various GPIO signals to different boards. Is anyone aware of a product that can do this?

I wrote a Bootloader for my STM32F042k6 board that functions pretty well. On System Reset the Bootloader is launched and can later jump to the Application. That was great:). Now I wish to do the opposite in my Flash. I wish Launch my Bootloader at a start address other than 0x08000000 lets say at 0x08007000. When I do the modifications in the Linker Script the Programm cannot be debugged. In simple words I wish to place my bootloader at the end of my Flash. Without forget that the Bootloader is always the first Code to run after Reset. Thanks in advance for your help and comments Here is my Linker Script:/* Entry Point */ ENTRY(Boot_Reset_Handler)   /* Highest address of the user mode stack */ _estack = 0x20001800; /* end of 6K RAM */   /* Generate a link error if heap and stack don't fit into RAM */ _Min_Heap_Size = 0; /* required amount of heap */ _Min_Stack_Size = 0x80; /* required amount of stack */   /* Specify the memory areas */ MEMORY { BOOTLOADER (rx) : ORIGIN
