Dear ST,I am trying to configure a simple zigbee centralized network with one coordinator and one endpoint, but I can't manage to correctly configure a rejoin request.As I understand it, a rejoin can be used to join a network as well. As per the documentation, the proper way is using the ZbStartup function with a startup control of 0x02 ZbTypeRejoin and setting the ExtendedPANId correctly (I have set one to this experiment). However, this results in a ZB_NWK_STATUS_INVALID_REQUEST. Using a ZbStartupRejoin after restarting the end device results in a ZB_APS_STATUS_SECURITY_FAIL from the aps layer, but the network keys are preset in both devices and operate on the default security level. I can't seem to comprehend why the procedures fails, I am definitely missing something. I would really appreciate it if someone could shed some light on joining, rejoining and its required configuration or point me to any material on this subject.Lastly. The devices will be part of a persistent netw

Hello,I am wondering if the presence of gel in the LPS28DFW makes it more susceptible to vibration than LPS22DF. These sensors will be in a vibration environment, and I'm concerned that the vibrating gel in the sensor will negatively affect the pressure readings. Is this a valid concern, or will the gel have negligible affects compared to the LPS22DF?Thank you.

Fault handlers that work on M4 and M7's aren't being executed on an M33.  The Usage Fault I'm creating (via an undefined instruction) appears to be escalated to a Hard Fault.  The Core stops executing instructions before ever reaching a handler.  Is this an artifact of some M33 security BS and if so, how can it be corrected?Thanks very much for any insight.

I am releasing my first product using a dual core STM32H745.  Our board manufacturer is using Segger J-Flash to load our application hex files.  The process for flashing our released firmware is to load a Segger project setup for the M4 core and our supplied hex file for the M4 core and program that memory address range.  Then repeat with a Segger M7 core project and our supplied M7 core hex file.Problem is that frequently I get a board that has only one core programmed which of course makes the board not fully functional.  Am I going about this the hard way?  Is it normal to combine the M4 core hex file and M7 core hex fie outputs into one and program the flash memory with a combined single pass?  Or is programming a dual core just a two step process and this will get better after we have built some more of them?  My compiler is IAR if that makes any difference.

Dear Community,I looking for some help - I need to be able to read a gamepad controller (in this case logitech wireless F710) with a H723ZG board.  I tried to adapt the mouse and keyboard examples without any success.With the HID_standalone example, I get the following output when I connect the wireless dongle:**** USB OTG HS in FS MSC Host **** USB Host library started.

Hey ST Community!I've been exploring the capabilities of the STM32H7B3I-DK development board, specifically its built-in WiFi module with the Inventek ISM43340-M4G-L44-10CF chipset. While I've successfully implemented HTTPS functionality using existing examples like the Clock and Weather application, I'm now looking to extend my project to include MQTT protocol support.I discovered that the network interface implementation provided in the Paho MQTT C client library is not directly compatible with the STM32 Network Library, which I am utilizing for network communication in my project.I've searched through available resources and examples but haven't been able to find a suitable MQTT implementation tailored for this specific hardware configuration. Has anyone in the community had success implementing MQTT on the STM32H7B3I-DK with the built-in WiFi module? I'm currently investigating how to adapt the Paho MQTT library to integrate with the STM32 Network Library.Any pointers, code sni

Is it possible to use the DTR/RTS pins of a UART bridge (such as FT232RL) to automate entering the bootloader in system memory for flashing firmware using STM32CubeProgrammer? Has anybody achieved this?

Hello, I just came accross the STM32WL series and I was wondering if I can implement a different modulation other than the ones included (FSK, PSK). I need to acquire an analog signal, convert it to digital and then modulate it with a frequency modulation and up-convert it and send it trough the PA. Can I do that using one of the STM32WL? Thanks.

I wonder if there are any discovery or evaluation boards that directly support connection to a 10.1" screen, and please do respond with something other than Riverdi. It would be nice if one could develop its own hardware without being overly dependent on third parties such as Riverdi. Has anyone managed to use the STM32747I-DISCO board (or any other board for that matter) with a bare 10.1" screen that has a 40-pin LVDS connector? So far I have only seen examples using the DISCO board with smaller screens. The 60-pin connector on the DISC board seems to carry a number of differential clock and data signals, so this looks like LVDS. Is it just a question of making a mechanical adapter from one connector to another? 

like the following code:   int ANDresult = i&j;   The value of ANDresult is 0x20022002. In our assignment our professor asked us to write down the address of the variable ANDresult, I tried to add ANDresult as an expression in the Memory monitor but the CubeIDE redirected to the address 0x20022002, which obviously is not the address of ANDresult.Thanks!Debugger: STLink V2MCU:STM32F103VET6

Hi Everyone,I'm trying to port LwIP to STM32H573I-DK and has referenced to:1. GitHub - STMicroelectronics/stm32h5-classic-coremw-apps at v1.0.0 2. GitHub - stm32-hotspot/STM32H7-LwIP-Examples: Ethernet examples using LwIP + FreeRTOS for STM32H7 Discovery and Nucleo boardsBut it still cannot work. The problems is that HAL_ETH_ReadData cannot receive any data after initialized.The attachment is my ethernetif.c and eth.c which including MX_ETH_Init and HAL_ETH_MspInitAnd STM32H573I-DK configuration is also attached.Thanks for everyone.

Dear STM32 team,I am a bit confused about the OCTALSPI device (using it as QuadSPI):Why is it not possible (not supported) to use OCTALSPI also as a regular SPI?Datasheet states that "Single-SPI" is possible - but it means actually: "Single-Lane-SPI": still in half-duplex mode (not possible to send and receive at the same time). Not regular SPI!BTW:It would be "cool" if the pin assignments (and ALT functions) would allow to use some QSPI signals also as regular (full-duplex) SPI signals. Why we, for instance, this mapping?OCTALSPI1_NCS = SPI1_NS    - nice: matchingOCTALSPI1_IO3   = SPI1_MISO - bad: map it to OCTALSPI1_IO1 - mismatchingOCTALSPI1_IO2   = SPI1_MOSI - bad: map it to OCTALSPI1_IO0 - mismatrchingand the SCK signal is on different pins: mismatchingIt is obvious for me, why OCTALSPI cannot work as "regular" SPI:It is NOT possible to configure an indirect read plus an indirect write at the same time (even the DIO1 signal turns properly to an input,

Hey,I tried to activate the HDP feature / secure software area on H753 following this documentation HDP secure area for STM32H7B3xx microcontrollers - Application note. I did only activate the security option byte not the secure software area itself. But I cannot connect via ST32 Cube Programmer anymore .- Error: No STM32 target found.My procedure so far:- Clear Flash- Activate Security option byte to get access to the RSS code- Implement jump in Bootloader via RSS_exitSecureArea - 0x1FF0 9514 (controller dependent)- Flashed Bootloader and Application- Cannot connect via Debugger Hot plug (and under reset as well)- Did not activate secure software areas yet Whats strange is, my display shows, that the application is started. Means, the jump via exitSecureArea does work. The application itself does as well works as expected. My understanding of the security option is, that it - forces the boot through RSS (therefore the need to connect as hot plug)- gives you access

I have a timer (TIM15) setup in trigger slave mode which uses CH1 for edge detect, and output compare on CH2. I have it working nicely to have the output low during the initial delay until the CNT reaches autoreload ARR. Then the output goes high as the output compare is 'Active level on match'. I then keep the oc in this state for some period of time (much longer than the resolution of timer can allow). At the end of this long period, I would like to be able to use the same delay triggered by an edge from CH1. I can get the final delay using 'inactive on match', but it doesn't wait for an edge on CH1, it just starts immediately. My main question is how can you reset the timer back into a state where it is waiting for an edge on CH1, without affecting the output on CH2? I want to hold the output high throughout the long delay and the also during the delay once the final edge is detected, until the output compare matches. If there are better strategies for timer setup, I'd like to hear

Hi!I am somewhat unclear on how to handle variable length transmissions using the STM32F4xx HAL. I have looked at other solutions, and suggestions have been made to use HAL_UARTEx_ReceiveToIdle_DMA() or the ISR equivalent.My situation however, involves a continuous non stopping transmission from a NEOM8N GPS Module. The GPS has a default baud rate of 9600, which I have observed in my code. It uses the NMEA0183 protocol, which has a max sentence length of 83 characters. Any suggestions on how to implement the receive function for this GPS?

Hello,We currently use diode 1N5711 in an array. It would be beneficial to have matched batches as mentioned on the website 1N5711 - 70 V, 15 mA RF and Ultrafast Switching Signal Schottky Diode - STMicroelectronics.I'd like to know more about the matching process and what the deliverables look like.

Hi.I was in the middle of a debug session in a simple application for the STM32F429I-DISC1 in Keil uVision. I disconnected my board from the computer without ending the debugging session. When I reconnected my board, it wasn't detected anymore and it enters debug mode (I know it because the LED1 blinks) as soon as I connect it. Now I can't flash or debug anything. Anyone can help? 

I am trying to configure TIM3 to reset on incoming PWM pulses and call IRQ on overflow, when pulses not coming. The prescaler and ARR are set for 150% of the PWM period. TIM3 in slave reset mode on trigger from CH2 input. MCU is STM32G051F8P.For some reason IRQ is called all the time, even when pulses coming.

I am having trouble displaying more than the first 6 lines of the display on my initial draw. As near as I can tell the touchgfxDisplayDriverTransmitBlock is called only three times and as a result only the first 6 lines of pixels are displaying correctly. Can't understand why is is just stopping and not being called again? SPI are in polling mode and no interrupts are being used. Any suggestions would be appreciated.Code is below: (Displ_SpiAvailable is set when SPI transmission is happening and reset when it is not) touchgfxDisplayDriverTransmitActive is only called three times as well. The application is set to use a partial buffer.  /* Private function prototypes -----------------------------------------------*/ /********************************************************** @brief TouchGFX integration: returns status of* communication to the display* @return 1 = there is a transmission running* 0 = no transmission***********************************************

I used the sample code of "en.stm32cubef4-v1-28-0\STM32Cube_FW_F4_V1.28.0\Projects\STM32F401RE-Nucleo\Examples\UART\UART_Printf"I just printed the "test" in the while(1) loop. but the display of my computer is werid, and I checked the clock and hal level code, the clock frequency and data transfer is correct.there are data tranferred on the serial port. I captured from SB63 test point and use the PICOscope The USART2 frequency was set to 9600. And I think the USART2 use the APB1 bus frequency: 42MHzGPIO groupA connected to AHB1. I uploaded the modified code on the github: https://github.com/amazingHH/STM32_UART/tree/main/UART_PrintfI have two boards, and I tested each of them, they have same problem. So, is it a USART clock problem?BTW, I used the KEIL project in the sample code.

Good Morning,I am working with an engineer that needs to asses the current based on the states of the STM32WB.  Is the simplest approach to use the Nucleo Board with the part and then, reviewing the schematic, place a current meter in line with the jumper between VDD and the MCU?  For clarification i have attached the schematic of the Nucleo board and on page 5, JP3?  I realize this is a sort of nebulous question but I had thought you could use the power monitor with one of the nucleo/DK boards.  I believe I was wrong.  Thank you!

Hello,I'm curious if I am going through the correct procedure to put th H753I eval board in DFU mode. I have the power jumper JP10 on PSU. I then put a jumper on JP3 which is labeled BL_BOOT0 (which as far as I know puts the H7 in DFU mode when pulled high). I then plug in the PSU and then plug in usb cable to my pc and to the eval board. I've tried all three OTG ports, but I get no activity on my pc. When I check device manager, nothing new shows up at all. I've seen other see STM32 BOOTLOADER and STM32 in DFU mode, but I don't see either of these.Any help or insight would be appreciated. Thank you.

For the last few days I have tried to download STM32CubeIDE.Often the download page simply ends in an eternal spinner or a page fault.I see others reported the same december 2023 and it appears it just sorted itself.Others see the same now?I have tried a few different browsers/machines, cleared cashes and cookies. nothing seems to help.A different account didn't help either.

Good day.I'm working with a NUCLEO-U5A5ZJ-Q and I'm looking for the schematic - but it does not seem to be on the product page.The user manual contains some indication regarding connector usage and high level soler-link configs, but I would like to see the full schematic.Any help would be appreciated.Thanks
