Hi,For production I don't want to use AAT_A and AAT_B features on ST25R3916 device. Can I leave these pins unconnected? What part of rfal should I remove to do this?regards,gaston

I know that there are a lot of questions and request for graph widget, yet there is no dependeble answer has been provided. It seems that there was a graph widget in previous versions, unfortunately not available now. I wonder if there is any ready to use graph widget that I can add to my project. The most needed feature is the ability to be updated and be able to shift the graph to the left side. The rival product (STEMWIN) has this feature.

The STM32F0Discovery board comes with accompanying example source code, traditionally. However, now, the relevant download page advises that this is all provided by STM32Cube, but it is not. There is NO example code in the STM32CubeMX / IDE for this board.What to do? How can I get the example source code for this board in the age of STM32Cube?Thanks.

We want to develop our own Boot-Loader for STM32H725/735 , is there an Written Example User Specific Boot-loader Source code from ST for STM32H725/735 to work with USART and CAN protocol

Helo.I have a Nucleo-32 development board with STM32L432KC MCU. In RM0394 , chapter "Real-time clock (RTC) applied to STM32L43x/44x/45x/46x devices only" I found this: "Output functions: RTC_OUT which selects one of the following two outputs:– RTC_CALIB: 512 Hz or 1Hz clock output (with an LSE frequency of 32.768 kHz)......RTC_OUT, RTC_TS and RTC_TAMP1 are mapped on the same pin (PC13).......In addition, it is possible to remap RTC_OUT on PB2 pin..."But in STM32L432KC datasheet ,chapter Pinouts and pin description, I can't found pins PC13, PB2. Moreover, in CUbeMX when I select STM32L432KC MCU ,on RTC tab in Pinout & confiruation, I found no anything about RTC_CALIB output. Where is my mistake or datashhet missunderstanding ?Best regards, Volodymir.

Can you help me with fft? I don't know exactly how to use it. my goal is to separate the different frequencies.can you share sample code.

I have used NUCLEO-F072RB EVK <==> STUSB4500 and tried to execute below git code.https://github.com/usb-c/STUSB4500/tree/master/FirmwareI received below logs when source device attached:########################################################################=================== USB PD Sink Firmware v1.00 ===================STUSB4500 detected.

If I need to change memory areas in project (for example for Read-only memory I need 0x8080000 start, 0x40000 size), how can I do in in CubeIDE ? (addition) I have found Build analyzer, but the fields are not changeable, only view.

The board was working fine and then after some time i tried to connect again to flash via CUBE IDE but it didn't connect. I am getting the following error when i try to connect using STM32 CUBE PROGRAMMER.i am able to get EVA_H757XI mass storage when i connect the micro USB and also able to upgrade the firmware. I am powering the board using the power brick given along with the board. also attaching the board for your reference. please guide me through in solving this issue. Thanks.

The connections are quite simple Master-CLK , Master->MOSI to Slave->MISO and we only have one Slave so, we aren't using CS. We're only trying to receive simple data but, we're only getting various trash. We have experienced crashing and the clock signal being distorted before but, this went away as soon as we disabled the nss pulse. However, we're still unable to receive useful data. In debug and monitoring the the rxreceive buffer, it's as if there is no connections at all. Just trash. The master clock and mosi signals are doing what we expected though.This is usually a simple fix but, if anyone has insight where we should start looking to fix the issue it would be greatly appreciated!Our test code is below:#include "main.h"/* Private variables ---------------------------------------------------------*/SPI_HandleTypeDef hspi1;/* Private function prototypes -----------------------------------------------*/void SystemClock_Config(void);static void MX_GPIO_Init(void);static void M

Hello everybody!In my company We decided to use ST brand for our "NFC projects". Anyway, now I have Nucleo board 32f070RB and x-nucleo-NFC05a1 with ST25R3911B chip.For now We have a simple project, just to read and write to/from the Tag (some of the classical tags, probably ISO14443A).Unfortunately, there is no official Excample for x-nucleo-05a1 and 32F070RB. For now I just established SPI communication with microcontroller and 25R3911B chip(basic read/ write into a register).Now I need a help because I confused about 2 things and If It's possible to answer me: + What is the steps to Initialize ST25R3911B and start communicate with Tag (I read a datasheet but it's a bit confusing for me)?+ Is it necessary to use rfal and/or st25r3911 libraries or at list which is really necessary?All the best,Domen

In addition neither the datasheet nor the reference manual mention how to access it but the older (pre HAL era) driver versions did support this. The backup registers are even missing in the RTC register map of the reference manual even though these registers are clearly available on all F0 MCUs.

Hallo everyone.I am evaluating this platform and I got it to work with the UDE STK debugger env.unfortunatley when I shutdown my laptop at the end of the day, it seems to loose all the driver settings.The morning after when I try to connect to the boar dit gives me this error message:Message from component 'PpcJtagTargIntf' :Can't connect target !Message from component 'PpcJtagTargIntf' :No JTAG client found !Please check:- target power supply- JTAG cable connection- target configurationI am on W10 Pro x64. I connect the eval board USB cable to the dock (but it has same behavior even if I use the laptop's own ports)The drivers for FTDI and PLS USB JTAG adapter are installed and configured in device manager settings:I don't like having to reinstall the UDE STK 5.0 every day...Has anyone faced the same problem? how did you fix it (if ever)?Thanks in advanceMaurizio

Hi ,all.I wanted to understand where the 16 in this equation comes from, cna anyone epxlain?

I am working on a custom LCD project using STM32h753 Eval 2. Currently i dont have a tremendous knowledge in LCD. I tried to follow the example codes and some tutorial but not able to make it work. can you suggest any resource or steps to get started?i am using a custom 1024*768 LCD. This LCD receives signals through LCDT. the config given by the manufacturer is #define PanelHSyncWidth      43 #define PanelHSyncBackPorch   29 #define PanelVSyncWidth      6 #define PanelVSyncBackPorch   34 #define PanelHStart      (PanelHSyncWidth+PanelHSyncBackPorch) #define PanelVStart      (PanelVSyncWidth+PanelVSyncBackPorch) #define PanelWidth      1024 #define PanelHeight      768 #define PanelHTotal      1344 #define PanelVTotal     &nb

I'm Using the Cube Programmer, I get an Error reading the Location 0x1FFF1E80-8B ( unique MCU ID ) on the STM32H750ZB. I can read the Code memory and connect . correctly.

I am selecting the microcontroller for an application that needs to implement an USB dual virtual com port (composite device with two vcom port). I would like to use the STM32F411 but i see that other people got problems trying to do it, maybe because of the few endpoints of this microcontroller. Can anybody explain me what is the situation?

Hi,I don't want to use the ST25R3916 capacitive card detection that involves CSI and CSO pins. Can I leave this pins unconnected? What part of rfal should I remove to do this?Thanks in advance,gaston

Hi,Where's the ST25R3916-EMVCO documentation? Schematics, BOM, gebers, User Manual.It is an available product? I'm not able to order it through any distributor.regards,gaston

I want to know how to specify the address to load Cortex-M4 firmware when U-Boot or Linux Kernel load the firmware of Cortex-M4 in Retention RAM.​And, how to specify the address to load Cortex-M4 firmware if I load the firmware of Cortex-M4 in Retention RAM and MCUSRAM separately?​In addition, if I load the firmware of Cortex-M4 in Retention RAM and MCUSRAM separately, is the swithing of RetentionRAM and MCUSRAM done by MPU without the programmer being aware of it?
