I'm migrating from ST25R3911B to ST25R3916B and i find that rfalTransceiveBlockingTxRx used with 3916B doesn't work with 15693-3 custom command. I get error=0x9 (framing error)I'm using the addressed mode on 3911B and 3916B, the message buffer is the same, the tag is the same (NTAG5). The custom command format is: FLAG - CMD_CODE - MFG_CODE - UID - BLOCK_ADDR - BLOCK_NUMBER - CRCFLAG is 0x22CMD_CODE: 0xC0MFG_CODE: 0x04The same function used in a custom write operation (CMD_CODE 0xC1) works, and it works for all standard write and read commands called before the custom read register wich fails.Thanks for any help

I'd like to use my own server instead of HSM card. I can't find any information how the license file is generated except the fact that it is possible as mentioned in AN5054.Slawek

What are the benefits of using OpenStLinux on STM32MP15 and how does it differ from other operating systems?Thank you in advance for your response :)

I'm just starting to learn microcontrollers, so I have a question.I have STM32F103C8T6 and STLINK V2 programmer.Connected lines SWDIO, SWCLK, SWO(PB3) and RESET In CUBE MX I choose "No Debug" or "Serial Wire" or "Trace Asynchrone SW" and in CUBE IDE with any choice (after flashing), there is debugging by registers and SWOWhy is it so done that debugging goes on, even if it is turned off in CUBE MXIn STM32 Utility also works, with debugging disabledPic

Hi! I am working currently on a stm32 F407, I am implementing USB Communication Device Class with the microcontroller being a device. The microcontroller is powered via the STLink but I wanted to change that and supply it through the usb I am using for virtual communication. On the data brief, it says that the board has a Flexible power-supply options: ST-LINK, USB VBUS, or external sources. I assume that I have to use the USB Vbus.The reference manual says that :On-chip 5 V VBUS generation is not supported. For this reason, a charge pump or, if 5 V are available on the application board, a basic power switch must be added externally to drive the 5 V VBUS line. The external charge pump can be driven by any GPIO output. This is required for the OTG A-host, A-device and host-only configurations. The VBUS input ensures that valid VBUS levels are supplied by the charge pump during USB operations while the charge pump overcurrent output can be input to any GPIO pin configured to genera

We are looking for a replacement of NXP microcontroller LPC1764FBD100. Can you please suggest a suitable ST Microcontroller?

I am having trouble with USB-FS communication with STM32F107RCT7.When the board is connected to the PC via microUSB, the PC does not even detect something is connected to the PC.I know that the PC detects a new device via a pull-up resistor on either DP or DM lines. In my case there needs to be 3.3V on DP pin via an Internal Resistor inside the MCU.Checked the voltage on DP, it is zero.Tried to debug the issue in STMCubeIDE:I found the function responsible for USB initialization: HAL_PCD_MspInitBut there were no pin initialization for DP or DM pins.Throughout the whole project I could'tn find any initialization on DP or DM pins.Added the following code in HAL_PCD_Mspinit__HAL_RCC_GPIOA_CLK_ENABLE(); GPIO_InitStruct.Pin = USB_FS_DP_Pin|USB_FS_DM_Pin; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH; GPIO_InitStruct.Pull = GPIO_NOPULL; HAL_GPIO_Init(USB_FS_DP_GPIO_Port, &GPIO_InitStruct);Still no 3.3V on DP pin.I cheked the DP pin on nucleo F767ZI

1. Terminal setting: classic can, silent mode, 250kbps, commercial vehicle, stm32g4742. Symptom: There is no problem during the test, but sometimes a problem occurs with the vehicle, probably because of a can error. Symptoms not reproduced.3. Inquiries: -. Can our terminal affect the external can bus in silent mode? -. How to perform recovery in firmware when can bus off occurs?

im debugging an LTDC project for the stm32f429zit6 on the disc board and in the sfr tab under rcc apb2enr it stops at tim11 and doesnt show ltdcen why is that and it seems my configurations in the ltdc registers arnt being set . im looking in the .svd file on from what i can see LTDCEN isnt in there im attempting to add it but im not sure what all i have to do

Hello, we are working on new release of STM32WL "STM32Cube_FW_WL_V1.3.0". release which has introduced changes in RTC driver which we believe is fixed for the issue (RTC loosing time issue STMicroelectronics/STM32CubeH7#24 )But, after running RTC overnight we have seen RTC issue is still persist in different manner this time RTC is increasing timeTest Start time : 17:55:56, UTC time 1670415956Test End Time: 9:48:00, UTC time 1670473080, (57124 Seconds)Difference of UTC time should be : 57124 (1670473080 - 1670415956)But, From attached logs we can see Test End time is 9:48:00 and total seconds are 57135s837 (check last line in logs).RTC had generated 57135s837 seconds instead of 57124 Seconds.So, 57135 - 57124 = 11 Seconds are increased in actual timeRTCTestLogs.txtRTC Driver.zipDriver files are also attached for more details.Can someone please explain how to fix this?

On the website, in the databrief it is not stated how to connect the jumpers on the steval-mki227ka, I would like to know how to enable SPI mode 1 on the evaluation kit for testing.The problem that I'm getting is that even reading the who am I address it gives back the wrong answer.All help will be appreciated.

hey there! in a recent video posted to the ST youtube channel about STM32WL rf layout, there's a reference to the existence and availability of four separate reference designs - MB1720, MB1842, MB1791, and MB1792 using STM32WL parts, but it seems none of these are available for access on the ST website yet. I'm interested to see them, because they seem much closer to the cut down approach to the design I'd like to do, as compared to the nucleo reference design which is available.Normally I'd just be doing my own cut down design/layout based on the nucleo design I have been evaluating right now, but if more work is already done on ST's side, it would be really nice if I could get the files to look at and start from there. Also the existence but unavailability of those designs is a little worrying.. are they unavailable because of a problem with the basic approach they follow? if so I'd love to know before I waste a bunch of time prototyping my own similar approach.

Hi, I have a STM32F767 project I recently updated to new software release: CubeIDE 1.12, CubeMX6.8 (both from previous versions 1.11.x and 6.7). CubeMX code generator now adds a check for flag VOSRDY after setting regulator voltage scaling in SystemClock_Config():LL_PWR_SetRegulVoltageScaling(LL_PWR_REGU_VOLTAGE_SCALE1); while (LL_PWR_IsActiveFlag_VOS() == 0) { }Before CubeMX 6.8 this was only the set function:LL_PWR_SetRegulVoltageScaling(LL_PWR_REGU_VOLTAGE_SCALE1);But the flag is never set at this stage. When I remove the check, my program runs fine again.I also created an emtpy project based on my .ioc (just deactivated ETH, USB, FreeRTOS, TouchGFX, USB and lwIP). No additional code, just the CubeMX generated code: Same behaviour! I can provide the project when needed.My observation of the PWR->CSR1->VOSRDY flag: It starts as 0 and gets only set to 1 later in the SystemClock_Config() function when calling LL_RCC_PLL_Enable();Can someone have a look at this please? ;)

I'm really uncomfortable keeping track of such small icons, which are also almost the same color as the background.I tried to find the brkp_obj.png file in the /opt/st/ directory (as suggested on stackoverflow), but did not find anything similar.Is it possible to change the size and color of this icon?

I am working on controlling of a stepper motor with STM32F446 and want to generate a PWM with variable frequency (trapezoidal) and stop it after some specified (n) pulses. I want to do this with register programming not HAL functions. So I want to know three steps bellow:How can I generate a PWM pulse with registers?How I can change its frequency?How I can count generated pulses and stop generating after som pulses?could someone help me in register programming?

There doesn't seem to be any documentation on whether the optional battery holder CN15 can be used on the unit, nor what it's specs should be if it is populated with a battery. I need constant RTC backup from the time the unit is first configured.

Hello,I am trying to use an LCD display on my custom board. I am utilizing the Rocktech RK043FN66HS-CTG display with the STM32H7B3IIT6 MCU. When I first initialize the firmware (in debugging mode), the screen flickers once or twice (showing signs of life), but then immediately goes to a black screen and stays like that.

I have sufficient RAM space internally)480 x 272 RGB565 display (hardware can handle up to RGB888, but to reduce RAM size, I am only using RGB565). Using FreeRTOS to do the TouchGFX taskI used this video as a general guide to make sure I got the right idea, but there are differences. However, he has the same issue during debugging that I am seeing. The screen flickers then goes black. https://www.youtube.com/watch?v=SRQD8JMeg_kIn that video, he notes that it was due to improper

I am using ST25DV64KC and ST25PC-NFC v 2.61 on my pc with windows 10. The software opens just for few seconds and then closes by itself. I have installed it thrice. I tried restarting my pc as well but nothing helped. Kindly let me know what can i do to use the software. Thank you.
