Hi,I could generate a single pulse to the HRTIM CHA1 by using HRTIM EEV6 (I tried with EEV1, but it did not work). Is it possible to generate a single pulse by using other high-resolution timers or timers? In the CubeMX, timers can be selected as a reset trigger source in the Reset Trigger Sources Selection. I tried it with the HRTIM master timer, but it did not work for me. I read the HRTIM Cookbook, and the "Multiphase buck converter" example describes that single-shot re-triggerable mode is used with the master timer, so I assume that it should work.Is there an example project/code for me to try with?Thanks!

I use CLI for flash F469 and same hex file flashed over SWD without error produce over DFU this. is this know issue ? Seems code is ok after both loads.

I have used MxCube to enable an ISR that is triggered from an external GPIO input pin. MxCube enables this ISR from the autogenerated MX_GPIO_Init() function by calling HAL_NVIC_EnableIRQ(EXTI15_10_IRQn); at the very end of this function. I don't want to enable this ISR until later in the program when the rest of my system is ready and it is safe to do so. How do I properly remove this line of code so that MxCube doesn't undo my change every time I go to update the MxCube file?Thanks!

My EVB NUCLEO-U575ZI-Q is not responding. When trying to run/debug, I get the following message:Target no device foundError in initializing ST-LINK device.Reason: No device found on target.Besides that, LED6 and LED4 are red.How can it be fixed? Is the board ruined?

Hello,I am attempting to add CAN communication to one of my co-worker's boards, who is using the STM32F303RE MCU with an external 30 MHz crystal oscillator. The CAN communication uses the APB1 Peripheral Clock, which is currently using 30 MHz as well. When I attempt to make a specific baud rate (250 kBit/s), I used http://www.bittiming.can-wiki.info/ to get the parameters to achieve that. When I put the values in, it shows the baud rate in a greyed out section that says it's 249.999 kBit/s.What I want to know is if that will cause issues when actually applied? Since it's not "exactly" 250 kBit/s. Has anyone else had this occur and can say whether it works or not?

Hi,I have downloaded en.x-cube-nfc5 project from:st(site)/en/ecosystems/x-nucleo-nfc05a1_htmlI have connected the X-NUCLEO-NFC05A1 Shield to one of my lab boards, based on STM32F103.I managed to make the whole thing work with this example: ndef_example_read.c (see below)I even managed to read one of my tags (NFC type 4A)I have ST25R3911B-DISCO board too as an exampleI run it with "NFC Type 4A - NDEF Message user interface"there are two options in the supplied ST Windows software:Present Read Password for read NDEF messagePresent Write Password for write NDEF message and with those options I can read or write my tags with a 16Bytes password length.I need to do the same with my board (the one with STM32F103), directly connected to the ST25r3911b, and so far I can't find how to define and send those read / write passwords.ndef_example_read.c:#include "utils.h"#include "rfal_nfc.h"#include "ndef_poller.h"#include "ndef_message.h"#include "ndef_types_rtd.h"#include "ndef_types_mime.h"#

Would you be able to provide electrical specifications for the integrated SMPS of STM32U585CIU? Specifically: power efficiency at different loads, output current capability, switching frequency, etc.Thank you,

The errata sheet ES0500 - Rev 4 mentions a workaround for 2.8.3 DMA stream locked when transferring data to/from USART where bit 20 of register DMA_SxCR shall be set. This register is not mentioned in the reference manual and not in the respective header files of STM32CubeWL.Q1: Is the mentioned errata relevant for the STM32WL5x family?If yes:Q2: How is the workaround implemented, e.g. where is register DMA_SxCR?Thanks!Carsten

Hi, I've got an STM32WB15CCU6 on a custom board and am currently trying to get it to boot from Flash memory after programming it with the STM Cube IDE.Debugging a program in the IDE works perfectly fine, but if I flash it to my microcontroller (using SWD) and remove the ST-Link from it and supply it from a different source, my LED blink demo doesn't run anymore. The BOOT0 pin is on GND via a 10kOhm resistor, this is my pinout from the IDE: I looked up the Option Bytes via the STM Programmer and they all seem to be set correct, as described in the boot process FAQ.In the PCC Tools, the configuration looks as follows: Does the Memory Fetch Type have anything to do with from where the MCU boots during a normal boot process and if so, do I have to set it to F_FLASH? It is currently set to SRAM1. If all of the above are correct that way, what else should I check to get the boot process to run correctly? Thanks a lot in advance!Best Regards, Nik

 I have a big project in C that was created by other people, it builds and run well on STM32CubeIDE. I want to create DLL file out of this to expose the functions used inside so that it can be used by other programming languages.

Hello :)Does anyone know what the impedance of the existing antenna matching circuit on the X-NUCLEO-NFC06A1 board is? I can't seem to find that information in any of the datasheets. I need the impedance so that I can design a new custom antenna. Br. Jørgen

Hi,I'm new with RFID technology especially when it comes to designing antennas on boards and calculating matching circuits but... I have successfully designed and manufactured my board with ST25R3918 and I have a few questions.I have a 43x43mm on board antenna with other electronics inside it, I have done 0.5mm spacing between antenna and ground polygon surrounding ST25R, uC and some serial communication ICs. Now I have about 8.5cm range with the 5x5cm tag (ST25TV02KC with ISO15693) from ST25-TAG-BAG-UB but only 3-4cm range with the button tag from that bag. Is there anything that I should do to increase the range? I have thought about two things: Firstly, redesign the "internal" circuitry to increase the spacing between antenna and ground. Secondly, change the RFID reader to ST25R3916B with greater output power (1.6W and ST25R3918 only 0.5W) but I don't know if it is possible to just desolder ST25R3918 and solder ST25R3916B in the same place(Can Auto Tuning circuits be a problem?).Nex

Hello I have two STM32WL55JC2 boards and I would like to run the PingPong DualCore example available in this WL package folder : I run the .project file on the STM32 IDE and I get this: After adding several missing .h files I manage to flash to the boards but I think I am missing a step.In the tutorial it says: " - Open your preferred toolchain - Rebuild all CM4 files and load your image into CM4 target memory - Rebuild all CM0PLUS files, set PWR_CR4_C2BOOT flag via CM4 and load your image into CM0PLUS target memory - Do the same for second board - Reset the two boards - Run the example on two boards - Open two Terminals, each connected to their respective PingPong Device - UART Config = 115200, 8b, 1 stopbit, no parity, no flow control"It's not working from now on and i think i've missed something but i can't find what."Rebuild all CM0PLUS files, set PWR_CR4_C2BOOT flag via CM4 and load your image into CM0PLUS target memory" i don

Creating the project with CubeMX for the STM32H743i_EVAL board and allowing it to generate the Initializing function and call for the SDMMC1 (or 2 for that matter), generates initialization code that attempts to power up the card without checking to see if there is a card present. Obvious failure waiting to happen. And even if there is a card present, the power On function is doomed to fail because the code never exectues the SD_MspInit wich enables all the io for communicating with the card. I am curious to know why that code is not present in the GPIO initialization functions? If that is not bad enough, it gets worse when the BSP code for SD is added to the project, it causes all sorts of compiler errors because of duplicate definitions.
