Hello everyone, I want to obtain the relevant sample program through AutoDevKitStudio-2.4.0. How can I obtain this License?

Moved from MPUs forum: STM32C0 is an MCU - not an MPU. Hi, I am not sure if STM32 cryptographic firmware library can run on STM32C071 because this microcontroller does not have embedded Crypto (Hardware) ?   Thanks   Gregory Saint-Jean

Hello all, for STM32H757xI in package WLCSP156, I didn't find a clear explanation about connecting capacitors for power supply. According to the schematic from STM32H757xI  kit, it looks like all VDD_MCU pins need to connect 100 nf capacitors, Only in my case, I can do that, since not enough place on the PCBI wanted to ask, does it have any opportunity to connect VDD_MCU pins to each other and connect to more powerful capacitors. If yes, how can I calculate nominal for capacitors in this case I want to do like here

Hello, I have a STM32WBA55G-DK1 board, and i'm trying to build the example code for the Unicast server (BLE_Audio_TMAP_Central example project). I'm importing it using the GUI (new project, example, then i select the example).  I haven't modified anything in the code, but when i try to build it, i have the following error (see image bellow)  I tried to compile another example code (using the same steps as with the one giving errors), and it is working as intended. Can you help me please? Thank you.OS: Windows 11, last version CubeIDE: last version 

I'm trying to get a USB virtial COM Port working on the STM32 Nucleo-H745ZI-Q. I've generated some minimal code to initialize the device on PA11 and PA12 and have tried connecting a four pin USB-C breakout board to wire GND, DP, DM, and U5V, as well as simply using the provided user usb port, but no luck. My configurations are as follows in the screenshots and code.My expected result is to view all COM ports connected to my computer and see this pop up, currently that is not happening.- USB set to device only on CM7- USB Clock source is from RC48- USB device set to CDC with default settingsAny help would be appreciated, I am sure I am missing something minor hereint main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* USER CODE BEGIN Boot_Mode_Sequence_0 */ int32_t timeout; /* USER CODE END Boot_Mode_Sequence_0 */ /* MPU Configuration--------------------------------------------------------*/ MPU_Config(); /* USER CODE BEGIN Boot_Mode_Sequence_1 */ /* Wait until CPU

I am running into a difficult bug when trying to use the SVG and vector fonts on the STM32U5G9NJH6Q that may be related to this specific variant of the chip, or to the dimensions of the RGB LCD that is being driven (or both).  The problem is that SVG images (even a single basic rectangle) end up having a "shattered" look where there are many holes/tears and random lines and shapes that almost make it look like shattered glass.  It also tends to be more prominent on the top left of the image (regardless of size).  A basic square also showed an 'X' shape like it is split into four parts by a fine line (even following rotations).  The strange thing is that animations and rotations of even large SVG images work well (despite the rendering issues).I also have an STM32U5G9J-DK2 where the SVG feature works perfectly fine.  I have built and debugged the demo 7 project in STM32CubeIDE, so my tools appear to be fine (unless this is a hardware issue with the NJH6Q package

Hi. I have worked on a project for a long time but had to swap CPU because of lack of memory. Before my device was STM32h743VG6 and I switched to STM32h743VIT6. Since i couldn´t just swap the CPU in mx without starting a new project, I swaped CPU and imported the files into a new project. It compiled and could run after some changes in the  FLASH.ld file. When generating new changes from touchgfx and programming to the flash I got memory issues. Some of them depended on path locations of files which i fixed. But one of them gave me this right before entering MemManage_HandlerNo source available for "<signal handler called>() at 0xffffffe9Somehow I can´t find the address. Any advice on what can be wrong ? 

Hi,I am designing an NFC reader based on the ST25R3916B for a payment interface, ensuring compliance with EMVCo standards. For hardware development, I am using the ST25R3916B-EMVCO reference design as my baseline.Queries:Custom NFC Antenna Design:I plan to use the same NFC antenna dimensions (51mm × 27mm) and trace length as the reference board but will design it myself.How should I approach designing the coil to ensure proper inductance and matching network?If I change the coil shape but maintain the same number of turns and total trace length, will the matching network also need to be adjusted, or can I use the same network as the reference board?Impact of Display on NFC Performance:My design includes a display on the surface of the reader. Will the display impact NFC coil performance?Should I place the NFC antenna under the display, or is it better to design a ring-shaped PCB antenna around the display to avoid interference?Using a Third-Party NFC Antenna:Since EMVCo certification i

Hello again, dear STMicroelectronics team,While reviewing the schematic sheets of the STEVAL-IPM10B Evaluation Board, I came across a connector pin labeled 'PWM_Vref' (highlighted with a green circle in the image below). However, I couldn't find this pin mentioned in any of the other schematic sheets.I would like to ask: What is the purpose or function of this pin?Thank you in advance for your support.Best regards, 

Hello,I have an application which I would like to build on to of cubeMX generated HAL driver, but I came across strange issue that I am unable to keep RTC value on reset. Drivers part is as generated with cube using freeRTOS. system reset is triggered with `NVIC_SystemReset()`, MX_RTC_Init is as follows:/* RTC init function */ void MX_RTC_Init(void) { /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ RTC_TimeTypeDef sTime = {0}; RTC_DateTypeDef sDate = {0}; RTC_AlarmTypeDef sAlarm = {0}; /* USER CODE BEGIN RTC_Init 1 */ /* USER CODE END RTC_Init 1 */ /** Initialize RTC Only */ hrtc.Instance = RTC; hrtc.Init.HourFormat = RTC_HOURFORMAT_24; hrtc.Init.AsynchPrediv = 127; hrtc.Init.SynchPrediv = 255; hrtc.Init.OutPut = RTC_OUTPUT_DISABLE; hrtc.Init.OutPutRemap = RTC_OUTPUT_REMAP_NONE; hrtc.Init.OutPutPolarity = RTC_OUTPUT_POLARITY_HIGH; hrtc.Init.OutPutType = RTC_OUTPUT_TYPE_OPENDRAIN; hrtc.Init.OutPutPullUp = RTC_OUTPUT_PULLUP_NONE; if (HAL_RTC_

I have been using SPC5-UDESTK with a STM58 evaluation board. I now need to start working with multiple cores, but it appears that the starter kit license does not support this functionality. Will the SPC5-UDEDEBG license allow for multi-core debugging? The documentation for SPC5-UDEDEBG specifies core 2 only, while PLS mentions multi-core support for the SPC58 family. If SPC5-UDEDEBG does not support multi-core debugging, what other tools have users successfully used for this purpose?

I try to combine the enocer mode of TIM1 with a encoder clock period measument using TIM8. The RM0456 (for U5) mentions this in the end of chapter 54.3.25 under the heading "Encoder clock output". TIM1 works fine and counts up and down according to the encoder signals. Now I want to measure very low speeds where encoder pulses happen only "now and then". My settings: * TIM1 CR2 MMS set to 0b1000: tim_trgo = Ecoder Clock Out* TIM8: Internal clock scaled down to 1Mhz (works fine, it counts as expected)* TIM8 CCMR1 CC1S set to 0b11 = TRC* TIM8 SMCR TS = 0000 = tim_itr0 = TIM1 trgoafter enabling TIM8 and TIM1 I never get an actual capture - somehow the trgo - TSC - CC1 signal chain seems not to work. Does anyone have an idea what I am missing? 

I urgently need to get USB High Speed working on USB1 of the STM32N6570-DK. I have attached the .ioc file I am using.I am able to get the GPIO_IOToggle project working on the board. I am able to put breakpoints step through the code.I am using  STM32CubeIDE version 1.18.0 (Build: 24413_20250227_1633 (UTC)).As a second step, I need ThreadX working on the board. 

I have RFID reading with ST25R3911 working now with RFAL and  I would like to sense if there is a RFID tag nearby before starting RFID reading. I did not find any example code in RFAL. I looked into data sheet and tried to read the registers:st25r3911ReadRegister(0x3C, &c); printf("CapA %d\n\r", c); st25r3911ReadRegister(0x3D, &c); printf("Cap %d\n\r", c); st25r3911ReadRegister(0x2B, &c); printf("Volt %d\n\r", c);but I just get zeros:CapA 0Cap 0Volt 176 How shall this be done?

I am trying to use the bootloader of the STM32G474QET6 with USART to program my microcontroller. I have multiple questions regarding this but the first one is more about hardware. I have found in AN2606 that for the bootloader I can only use one of three USART, as listed under :So after this info, I can use either USART1, 2 or 3 but when I look at the pins attached and at the datasheet of my microcontroller, pins for USART3 on the MCU are not PC11 and PC10. The thing is on my PCB I've decided to use PB10 and PB11, and according to the datasheet, they are the pins of USART3.So my question is pretty simple, which document is right and which should I follow ? Am I going to need to change anything ? Thanks for the answers !

I have a new STM32U5G9J-DK2 board. I have to port an application running on STM32H747I-DiSCO board.I have a big problem with setting brightness in the new board. In STM32H747I-DiSCO app I used:extern "C" { void LCD_SetBrightness(int value); }The LCD_SetBrightness() function is implemented in TouchGFXHAL.cpp file for the H7 processor. The same thing does not work with U5 processor because the TouchGFXHAL.cpp file does not contain the LCD_SetBrightness() function.So, the question is how I can set the LCD brightness in STM32U5G9J-DK2 board.I tried using the brightness control implemented in Board Support Package but calling BSP_LCD_SetBrightness(0, 50)  (50% brightness) causes Hard_Fault() interrupt... Nice!Can somebody help? Thanks,Louis 

Hi Everyone,I interfaced Nucleo F767ZI with W25Q256JV using SPI and everything was working fine. But due to time and speed requirements, now I have to shift it to QSPI. I have used example code of STM Document named "QSPI_F769_discovery_flashloader" and developed a code for QSPI. But whenever I try to run the code and write/read the memory, nothing happens. I started to run code in debug on STMCube IDE and found that when try to send command to enable write and read status register, the register value doesn't change to write enable (0x02).Always fail here and Error LED turns ON.if (HAL_QSPI_AutoPolling(&hqspi, &sCommand, &sConfig, HAL_QPSI_TIMEOUT_DEFAULT_VALUE) != HAL_OK) { HAL_GPIO_WritePin(GPIOB, GPIO_PIN_7, GPIO_PIN_SET); return QSPI_ERROR; }The Write Enable function is here.uint8_t QSPI_WriteEnable(void) { QSPI_CommandTypeDef sCommand; QSPI_AutoPollingTypeDef sConfig; memset(&sCommand, 0, sizeof(sCommand)); memset(&sConfig, 0, sizeof(sConfig)); /* Enab

Hi all,I'd just like to report an error on the reference manual for RMSTM32F411 (RM 0383 Rev 3).The error is located on page 471, on section RTC Register Map.The table showcase all registers for the RCC and miss the entry for RTC_SHIFTR (located at address offset 0x2C) and also for RTC_TSDR (located at address offset 0x34). Here, 0x2C and 0x34 are missing from the register map. 

When temperature below -15℃ , STM32WLE5CCU6 UART can't  receive any data from uart, But it can send data out from UART.,and The LoRa Unit worked well,It seems the TXCO is working. What's the problem? How can solve this problem?

Hello, ST experts The temperature sensor in STM32U595 is used for a mesurement. As datasheet said TS_CAL1 can be read at address 0x0BFA0710~0x0BFA0711. But this value is for 3.0V VREF, how is the situation if VREF and VDDA is 3.3V? How can I get the true temperature. E.g. for a chip I have the TS_CAL1 is 4130. What does that mean for 3.3V VREF? BRYang

Hello, would it cause any issues if 'PWR_GND' (highlighted in green) and 'SGN_GND' (highlighted in pink) are not referenced to the same ground?Thank you in advance. Best regards.

Hi to all.I'm testing the Nucleo U031R8. To avoid the Package issue i switch also to the old package firmware version (1.0.0), but same error.The example is UART_HyperTerminal_IT  and i simple cloned (or compiled directly in the repository), then execute without cars sending on the virtual comm port.The progran stuck in function "UART_CheckIdleState", because the timeout of function "UART_WaitOnFlagUntilTimeout" is set to 0x1FFFFFFU via macro.Is my new board damaged or similar? I've tried to rebuild the project via CubeMX (even in the recent 1.2.0 libs). No way. Thanks.

Hi,So I have been trying for last few days to port a library from Arduino and I am using STM32CubeIDE to generate code for the peripherals as it would be quick for my work and I do not want to change the Arduino code much other than the required things. The library is purely written in C++.I have created a C++ project in CubeIDE but it is generating main.c file. One solution that I found after searching on the internet was to rename the main.c to main.cpp. I did that and it worked, the compiler compiled ran the main.cpp successfully but whenever I change some settings through .ioc file it regenerates the main.c file and I have to move the changes from main.c to main.cpp. I am pretty sure that there have to be  a proper way to create c++ projects for stm32 boards. Suggest me whatever is the proper way to do this. Another solution that I found was to use main.c some how and call .cpp in main.c but I an unable to use that method because lack of understanding how that would work.Kindl

Hi.In AN5593, How to use the GPDMA for STM32 MCUs, on page 31, it says:"For some application needs, a timer request to GPDMA can be used to initiate a data transfer not involving timerregisters read/write, but other memory-mapped location, like for memory‑to‑memory transfers."How exactly do I do this?My precise use case: I have an 8*3 LED matrix, with the 8 rows connected to PA0:7. I have a uint8_t[3] of the data I want displayed and TIM8 configured at the frequency I want to update the columns at.Thanks for the help!
