Hi! A while back I started writing Rust driver for st25r3911b chip. Currently, it works and can read 14443A chip. The issue is that compared to official software (Discovery GUI) the read distance is about half. So if official software reads at 8-9cm then with rust driver it would just 5-6 cm.I feel like I have messed up some register configurations. My knowledge of RF is very limited. Could someone point me in the right direction of what I should look into?https://github.com/xpresshd/st25r3911b/blob/master/src/lib.rs#L168Thanks!  

Dear Mr MartinIn touchGFX I can generate the code but I can´t simulate with this error:Compiling generated/gui_generated/src/screen_screen/screenViewBase.cppgui/src/model/Model.cpp:4:10: fatal error: stm32f4XX_hal.h: No such file or directory#include "stm32f4XX_hal.h"//obrigado declarar^~~~~~~~~~~~~~~~~compilation terminated.I already reinstall TouchGFX, I already rebuilt all my project in STM32CUBEIDE and nothing.This library is present in the Stm32cubeIDE path project.Do you have any idea of what is causing this error: thanks, Best regards.PS:TouchGFX 4.22.0-STM32F429

I have program for CAN bus and NFC08a1 but when i combine i get several errors. All i want to do is get the reading from the nfc reader and send them on can. does anyone know how to do that?

Hello,STM32CubeProgrammer 2.13 has some bugs:See attached picture, the Target information does not report the correct flash size, although it is reading the memory size correctly at 0x1FFF75E0Why does it have to read multiple times in a row the same information ?When using an external loader, the "Deselect all" button does not work, clicking on it does nothing.Also with the external loader for an I2C EEPROM, you can't fill memory (of any size) at an unaligned address, even though nothing in the EEPROM prevents it.Best regards,Kraal

I bought ST25RU3993-HPEV kit to make my project. I try to program the programming board STM32L476RGT6 MCU in CUBE IDE (Not showing board). Then I try STSW-ST25RU001 (ST25RU3993 Reader suite), But not working as well, not reading and writing tags. My aim is to make a project using RFID with my own code. Does it possible to write my C program in this MCU board ? Please help to solve this issue. Thank you

I think RM0456, section 33.4.7 may be wrong describing ADC differential input polarity:"When channel “i” is configured in differential input mode, its negative input voltage is connected to VINN[i-1]."According to Figure 218 and my tests the opposite seems to be correct: negative input voltage is connected to VINN[i+1].  

I am trying to create a new inverter board for a Motor Control Workbench 6.1.2 project. I have tried several methods :1. Create clone of B-G431B-ESC1 in STMC Board Manager at choose Inverter stage of project wizard.2. Create new board in BM and save as required inverter name.3. Create new board in BM and save as required inverter name. Edit entry in BM to show correct "name" entry.Method (1) produces an entry in the "choose Inverter" part of the wizard, obviously without image. If I later try to create a new project, I choose general info and motor OK, but when I come to the choose inverter stage, my new board has disappeared, although it is still shown in board manager list, and is accessible for editing, etc. In fact all 3 methods above produce that same result, inverter is in BM list but not in project wizard choice. I noticed that the wizard says it is showing 12 of 12 inverters, the board manager shows a list of 14 inverters.If I search my whole PC for one of the inverters, say EV

Hi, the user loses a part of the screen:

Hi,I developed an application using the STM32G030 having UART working with interrupts. The UART initialization is done by the STM32CubeMX (attached). In addition, I have added code to enable the RXNE and Error interrupts using the LL functions "LL_USART_EnableIT_RXNE_RXFNE(USART1)" and "LL_USART_EnableIT_ERROR(USART1)".  Everything works fine except that as soon as the UART is enabled, the CMF, RXNE and FE flags are set and an interrupt is generated (since I have previously enabled the RXNE and Error interrupts). Is there any reason why the CMF, RXNE and FE flags are set as soon as the UART peripheral is enabled?Thanks

in ISO808 I have connected +5V at VDD and +28V at VCC. In my application isolation is not required so is it ok if I short GNDDD and GNDCC with filter?

For a project i need to add the sensor VL53L0X to a program, i've found the Library for the sensor ( STSW-IMG005 ) i can compil the program with no error , but don't work , i'm pretty sure it's from the adaptation from the library to my STM32, if you have a similar case or can help me it will be appreciated !

I configured USB_OTG_FS on STM32H745I-DISCO board using STM32CubeIDE.Here are my settings:My `MX_USB_HOST_Init()` function is called in `DefaultTask`.It completes without errors.`USBH_UserProcess()` is called whenever a USB disk is inserted to the port, with `HOST_USER_CONNECTION`.Then, in only one of like 10 different pendrives - I get `HOST_USER_CLASS_ACTIVE` state, then everything works, I can use any format on the USB disk. Via FatFs library. I tested it with FAT32 and ExFAT. Both seem to work perfectly without any issues.But I just can't buy another pendrive that works with that. 10 other pendrives don't work. I get `HOST_USER_CONNECTION` and that's it. Nothing. The device is not detected as mass storage device. What's especially infuriating, that it happens also with exactly the same looking pendrives. They have the same capacity, same speed, even the same look, branding and all. TBH: I have 3 pendrives that work with H745. 2 of them were bought together, in one batch, the other

Hi, I have tried programming and resetting this discovery Board but all I now get is this fuzzy grey screen as shown in the image is there anyway to do a hardware reset or is it a programming error? I just either want to reset the board back to its default state with a touchscreen menu, or a simple TouchFX example to work... Thanks

Hello, could you let me know which is the ST 3D Accelerometer chip with the highest accuracy? There is no need for gyroscope, neither for magnetometer. Thank you,Dimitris

Hi everybody, I need to integrate the ST25R3911B NFC reader (X-NUCLEO-NFC05A1 a.t.m.) into a project with STM32H735G running FreeRTOS (with a TouchGFX task and another peripheral task running ). https://community.st.com/t5/st25-nfc-rfid-tags-and-readers/interfacing-st25r3911b-with-stm32f072-using-freertos/m-p/570845#M8893 following this old thread: I integrated https://www.st.com/en/embedded-software/stsw-st25r-lib.html library (latest release v1.5), put NFC ndef r/w demo inside a task with st25r3911Isr called inside EXTI0_IRQHandler and actually it works! But, of course, the SPI reading executed inside an IRQ is not efficient, in fact, other tasks don't work properly. So now I'm trying to integrate the FreeRTOS_polling example, located in ST25R3916B / X-NUCLEO-NFC06A1 folder... it looks good to me but I can't get it working correctly, it instantly fails on the demoIni() where rfalNfcInitialize() returns 0x8 System Error. Has

I successfully ran the BLDC hub motor with sensorless method (sensorless + PLL) with EVSPIN32G4 hardware. My motor have the inbuilt hall sensor with 60 degree placement. Now, I am trying to configure with hall sensor. I get the speed feedback error in pilot software. I want to know some parameters in st mc wb software. Doubt no 1: In motor parameter in st mc wb have the placement electrical angle feature. I need to give the hall sensor electrical angle value of motor electrical value. if hall sensor electrical angle value means, how can I  calculate that angle. Refer the below picture. Doubt no 2: In speed position feedback management in st mc wb software, have the parameters of Average speed FIFO depth, input capture filter duration and use MTPA. Explain that parameters and how can I use. Kindly refer the below picture. Doubt no 3: If am enabling the hall sensor as main feature and enabling sensorless + PLL as auxiliary feature. If the main sensor fails, how c

In your document AN5766 Migrating within STM32U5 series microcontrollers.You mention that the JPEG Codec will be available in STM32U5Fx/5Gx. i try find this microcontroller in the Cube IDE but cant.do u have info about it or datasheet for it?RegardsM.Salem

Hi ST Team,I am using STM32U575 MCU. I want to create signed binary. I want to upload signed firmware in MCU and also update only new signed firmware via Native bootloader and want to restrict unknown firmware updates.How can I create signed firmware for STM32U5 MCU?Does ST's native bootloader verify signature firmware before updating new firmware or I need to add custom bootloader to restrict unknown firmware updates by verifying signature?If ST's native bootloader verify signature then when should I need to do configuration for that?Can you please guide me.Thanks in advance,VIJAY.

I have a very simple ADC setup for one-time conversion, only one Vrefint channel enabled, no DMA, ADC clock is 16MHz, MX_ADC4_Init() called with no error.HAL_ADC_Start() fails due to a timeout internally waiting for ADC_FLAG_RDY to be set in ADC_Enable() function.I am clueless, identical setup on STM32H7A3 works with not problems.CubeMX is the latest 6.8.1, hardware package STM32Cube FW_U5 V1.2.0

Hello ST Community,There was a thread by Aurelien about this topic, but I did not understand the answer. So let me rephrase the question with my own words.I have a STM32U5 based device with high security settings (TZEN=1, RDP=2). Is there any other means to regress to TZEN=0, RDP=0 than OEM2KEY provisioning and JTAG/SWD communication? By software?Regards.

Hi,I'm working on creating a simple soundcard with a simple codec called pcm5102a which is a part of the kernel source. My board is the STM32MP135F-DK. I2S seems to be enough for this purpose however if you think that SAI will work better, then I'll take advice on that happily as well.The current configuration is as in the attached audio_test.zip with I2S1 enabled and SPI1 Clock Mux set to PLL3Q instead of the default PLL4P (all set in the STM32CubeMX). The configuration is inserted into the build with a new machine and it does build without any problems. It's only after the boot that aplay -l doesn't list any soundcards, moreover below message is visible in the dmesg output:  [ 3.600504] st,stm32-i2s 44004000.audio-controller: Could not get x8k parent clock: -2 [ 3.607136] st,stm32-i2s: probe of 44004000.audio-controller failed with error -2  I read that the x8k is one of the clocks necessary for audio handling, however can't figure out how to fix that.Below are th
