Does not appear to be an appropriate label for my question. I can't find schematic for this board so I can map pins.  I read that this info is in user guide, but don't see it listed in user guide for the board here: https://www.st.com/en/evaluation-tools/nucleo-wb55rg.html#documentation     What am I missing?  The development board will be hard to use without board documentation.   -John

Hi,I've ran into an issue which is about start address of an application. I'm using an own bootloader to switch between two different applications. For the application I changed the start address in FLASH.id file to 0x08040000. That works perfectly fine.My problem occurs when I try to jump to the second application at 0x080a0000. It works too but the first application at 0x08040000 will be ran again.I figured out that it is because of the start address which is in both cases the same, 0x08040000. So probably the bootloader jumps to reset vector of 0x080a0000 and from there it jumps back to 0x08040000. If I change the start addres of the second application to 0x080a0000 everything works fine and I can jump from one to the other.Is there any way to provide an offset or so to keep the second application running in 0x080a0000 even if their start address is 0x08040000?I'd like to keep only two parts of the flash for the applications instead of three and copiing the data

Using STM32CubeIDE 1.15.1.  Running LwIP_Server_socket_RTOS on a Nucleo-H723ZG board.When I change #define LWIP_DHCP to zero my DHCP stuff is not grayed out.  It definitely starts using static IP, I'm able to connect and see the web pages.  I'm used to IDE's responding to #define changes, should I not expect this with CubeIDE? 

From the application schematics of VNF9Q20F, seperating my ground planes for CReg and DVcc but wouldnt DEV_GND (straight from the VNF9Q20F at the bottom) be connected as well instead of to battery ground? Shown as the drawn orange connection. Or both? 

Hi, I have an issue with CubeIDE and ST-LINK.I'm trying USART communication with STM32F0F4, I write code and debug but I don't get COM Port. In device manager there is no port showing. I installed st-link009.In CubeIDE, i tried both St-Link GDB Server and OpenOCD for debug probe but didn't work.I using Tera Term for COM Port connection, ST-Link not showing.

So as these things go I have an, two actually, ST NUCLEO-H503RB dev board that I cannot get the debugger to work with it.  My colleague on the other side of the country has the same boards and a similar setup and he is having no problems debugging.  We have also verified that the zero ohm jumpers on his board match my board (in case there was an install error at the factory). This is the error I get in Windows / Linux and different versions of the IDE: Error in final launch sequence:Failed to start GDB serverFailed to start GDB serverError in initializing ST-LINK device.Reason: (255) Unknown. Please check power and cabling to target. Here is what we have checked. Our jumpers are the same are in the same configuration and in the recommended positions for on-board ST-Link debugging (JP2/JP6 installed, 5V_STLN installed, JP1 not installed)We are using the same project.The firmware on the on-board ST-Link's have been updated to the latest version (that the IDE prog

Hello.I would use a static graph to display data. In the handletickevent function, I update the addDataPoint(x data, y data) function for the given page, but nothing appears on the graph, the scale is fine, but no line or change in the x direction can be seen on the display. I am currently using the tickcounter++ variable value for X data, which also increases in debug. For X data, I entered 0min, 200max data in the touchgfx program. I also tried the dynamic graph.Thanks if anyone can help.

Will there be any input impedence for the gpio's of stm32f429 If yes what is the value.

Hi all,I write to you because I would like to understand if it is really necessary to use an RTOS. I always develop projects with different ST processors (F4 and F7) without using RTOS. In those projects the F4/F7 processors communicate with many hardware components using SPI, I2C, RS232, GPIO and PWM. Now I need to increase the communication speed on the RS232, because I need do send few mega bytes of data every second and for that reason I need to integrate the USB with Full Speed or High Speed. Then in another new project I have to handle also a small OLED display. For all these reasons I'm thinking about the possibility to use Azure RTOS that seems well integrated with CubeMX, but I do not know which benefits I could obtain and if I could have some side effects both from performance point of view and also from developing time point of view.In this situation is it really necessary a RTOS?Which advantages and disadvantages could I have using a RTOS? Let me know!Thank you very mu

Hello,The chip I am currently using is SPC560P50L3, I need a unique MCU ID for calculation, but I checked the MCU ID registers of the two chips and found that the information is the same, MIDR1=0x56042416, MIDR2=0xA8005011. is this normal?Or if there is any other unique ID for this chip, please let me know, Thanks. 

Hello, I am trying to use STM32g071rb to control ST25DV16 chip. I found out that we can use middleware X-CUBE-NFC4 to code on stm32cubeIDE better. Question 1 is that when l tried to use I2C1 to connect with ST25DV16, l found out that I2C1 will no longer be automatically initialized in the code, and l wondered why. The second question is that after l configured X-CUBE-NFC4, why won't it initialize in the code as well and l can't initialize it myself because when it tries to do ST25DV_ReadReg() in ST25DV_Init(), the debugger will jump to HardFault_Handler(). The pictures below are my configurations. Thanks.      

Hi,I am implementing the st25r3916 firmware to be used in my reader. I have taken the code of "X-NUCLEO NFC06A1".To make the authentication, I am able to send the command 0x60 + block number; I receive the answer and I send the next message with the key and I receive an answer from the card with length 4 bytes, but I have the status of the reader  "RFAL_ERR_PAR". But when I check the received 4 bytes, they are the right ones. I am using the flags:RFAL_TXRX_FLAGS_CRC_TX_MANUAL|RFAL_TXRX_FLAGS_CRC_RX_KEEP|RFAL_TXRX_FLAGS_NFCIP1_OFF |RFAL_TXRX_FLAGS_AGC_ON|RFAL_TXRX_FLAGS_PAR_RX_REMV|RFAL_TXRX_FLAGS_PAR_TX_NONE|RFAL_TXRX_FLAGS_CRC_RX_MANUALIn order to continue with the reading, I was ommiting this error, and I am sending the command 0x30 to read, with the encryption (I know this part is well done due I have it already running in the st25r3911), in this case I am using next flags:RFAL_TXRX_FLAGS_CRC_TX_MANUAL | RFAL_TXRX_FLAGS_CRC_RX_KEEP | RFAL_TXRX_FLAGS_NFCIP1_OFF | RFAL_TXRX_FLAGS

Hi, i create a pipeline to compile a cubeide project with the cubeide in a docker container. on azure.the docker container is linux based as i found no solution to do a headless cubeide installation on windows(or is there a way?)in my project settings one of the build steps is to call a batch file for some code generation stuff. (this is needed during development so it does not get forgotten) normal development happens on a windows system.(it would not be necessary to do the codegeneration step if the project is compiled on the buildserver)as expected this does not work if i start the batch file in the linux headless build environment and it throws a error codeis there a way to skip this buildstep somehow? because at the moment this steps generates an error exit code which fails my complete build pipeline.to discard every errorcode is not an option because i cannot distinguish between a compile error and a buildstep error (or am i missing sth?)regards

Posted on December 13, 2017 at 17:32In Cortex-M3, M4, etc, we can just check the DEBUGEN bit in DHCSR (the Debug Halting Control and Status Register)http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0337e/CEGCJAHJ.htmlBut in Cortex-M0, that register is not accessible to the user code.:(So - is there any other way on an STM32L0 to detect when the debugger is connected? #stm32l0 #debug

Does anyone have, or know where I could find, a Radio Test / Radiated Emissions report for the ST25?  It appears to have the appropriate approvals so the report should be available somewhere, but I just can't find it. 

I'm working on emulating multiple USB devices using an STM32F4xx microcontroller. My goal is to dynamically change the USB controller's address at each SOF to cover the addresses of all my devices. However, I've encountered an issue: when I read the address from the hpcd_OTG structure, from hUsbDeviceFS and the DAD field, it differs from the address shown in Wireshark. Additionally, when I attempt to change the address, I don't receive any requests. The only way I can receive USB packets intended for that address is by resetting the address to 0. Any insights on why this might be happening?I am using "(void)USBD_LL_SetUSBAddress(pdev, dev_addr);" to set the address in the DCFG register and DAD fields.I have seen the Wrong software-read OTG_FS_DCFG register values erratum but the real problem is that only address 0 work.

Hallo ST Community, Which Part Marking has H3LIS331DL ? Thanks RegardsBadis

Hello everyone,  I am designing a PCB and I want a power path selector which can change the source between USB and Battery.Can I do this with STMPS2141STR ? I cannot find a circuit or an application note. This is my design is that correct ? Can somebody explain to me please

In STM32H503 USB device mode, I found that SOF interrupts are periodically lost, SOF interrupts trigger normally in about 300ms,then SOF interrupts does not trigger in the next 300ms,and so on, if ESOF interrupt are enabled, ESOF interrupt will trigger periodcally, I have checkd usb bus with logic analyzer, and the SOF signal always appers within 1ms ,there is no SUSPEND or RESET signal, What's wrong?

How can i add multiple charts to the dashboard? I want to use at least 2-charts in the dashboard, and monitor some variables (not an array) on a chart while some other variables (not an array) on a different chart. I have seen one chart + gauge(s) examples a lot. But all I need is to use two or more charts in the dashboard.

When Debugging the code in STM32 Cube IDE, the program execution flow directly goes into the HardFault Handler. The Debugging starts at HardFault Handler and I don't know why? Also this happened when I am trying to interface Sx1262 LoRa Module with STM32L496ZGTP. If anyone have come across similar issues please help me in this concern.Thank You

Hello everyone,I have a stm32h573. I want to get 24 bit resolution. There were those who said I could do it in dual mode. Can I get 24 bit adc resolution using dual mode? There is a 36 bit CDR register. But I really want to know if it will give 24 bit resolution. Can you help? Thank you.

i'm using the AC6.16 compiler and keil 5.34.i'd like to use DMA in UART,and the file dma.c occured in both CM4 and CM7 folder(UART is attached to cortex-m4).but when i want to compile CM4 and CM7 project,both have said that "multiply defined".how can i do to resolve?thx.
