Solved

Hello, I have two Nucleo-STM32F746ZG development boards daisy-chained together via their JTAG pins (refer to below diagram). When connecting a JLink Plus debug probe to the microcontrollers and attempting to debug the second development board in the daisy chain (Device #1), the connection fails and times out; I am only able to debug the first development board (Device #0) since JTAG assumes a single device to be connected by default, if not configured otherwise. Furthermore, when attempting to run the JLink Commander software, I cannot connect to either development board. I am using Visual Studio as my IDE/debug interface.I've tried:Adaptive clockingSlowing down the clock speed (from 4000 kHz down to 100 kHz)Running "-jtagconf 4, 1" in the JLink Commander software to program/debug Device #1. The programs responds with "Cannot connect to target".Setting "-jtagconf 4, 1" in my launch.json file for Visual Studio to program/debug Device #1. This yields a connection timeout.Setting "-jtagco

Which ST25R reader would you recommend for the MB89R118C Fujitsu Tag which has FRAM of 256 memory blocks/ 2048 bytes and uses ISO/IEC15693? For some reasons I could not write or read from this NFC type 5 tag with the NFC Tap app? Please advise.

hi,is ther a way to run Utility_timer and calendar simultaneously.if i set rtc on mixt mode or BCD mode, i do not receive alarm interruption ti manage Utility_timer

Hi,i am working on a Project right now where i need to send some data via LoRa. I'm using a STM32WL55 and i had some trouble with the radio setup, so to check the basic functionality of my radioi rebuilt the SUBGHZ_Tx_Mode example for my board and compared the actual example running on a Nucleo-WL55JC1 with my rebuild running on my board. The MXsetup is identical for both. I noticed that even before i start the code, i can see in the debugger, that on the nucleo the RFBUSYS Bit is set and on my board it isn't.Reading the documentation, i found out that if the radio resets, the RFBUSYS flag goes high, so it makes sense that at the very start the RFBUSYS flag is set on the Nucleo, as the whole board does a power on reset.But why doesn't the radio on my board perform a reset (or at least set the RFBUSYS bit)?How can there be a difference if no line of code has been executed yet and the Mx setup is the same?I'm completely lost on this issue, so any help is greatly apprechiated.

I'm trying to use the UNICO Pedometer Regression tool in offline mode to analyze accelerometer data from the LSM6DSO32 accelerometer. I have followed the instructions from the UNICO user manual regarding data format:-file name data_steps138.txt-data sampled at 26Hz-+/-8g full scale-data formatted to mg and tab separated, with x, y, and z axis data in that order on each line. Every time I try to run the tool I get a popup error at 1% completion saying "cannot open regression_tool.config". After closing that pop-up, the main window says "error: cannot generate configuration file". I have check the root UNICO folder and find no evidence of either file. Help debugging this issue would be much appreciated.

Hi,I just updated the CubeMonitor/CubeIDE/CubeProgrammer to the latest versions.After doing this my old version of Transparrent Mode (for STM32WB10) does not compile anymore.After creating a new project, and getting it to compile and run. I can now connect to my device through CubeMonitor-RF... sort of.It reads the version information and reports "Command Complet" but it says Unknown device CM4 version: No information CM0 version: No informationand when I try to read the HCI_READ_RSSI, the program freezes completely.The following screenshot is just after connecting.I can debug the code and pause the execution, but it is not in any fault handler.What can be wrong??? It was working under the last version CubeMonitor-RF V2.8.1last version of CubeIDE (before 1.9.0)

Hi All,Got it turning. Now need a guidance on where / what file and how I can control the speed. SDK 5.4.8.6S_STEVAL3202_SL_VM example.Monitor connects well.I can start the motor.Final ramp speed does not work. The only use - setting the direction of rotation.Measured speed raises from 0 to 4000rpm and motor stops with Fault over "Start-up failure". Motor power indicator jumps to max and stays there.My application is simple. I need an open loop control. 2 speeds forward, 2 speeds reverse. Stop. Preferably hardware control -3 pin. The only feedback - hardware Fault output.Questions are: Where (what settings) can be an error.Where can I find the code where I can control the speed.How I can control the speed (what variables are responsible for speed and acceleration?). I assume that it can be done in main.c in while(1) loop.Could you please direct me to some manual or documentation on 6S_STEVAL3202_SL_VM package.Thanks in advance for your answers.Regards,Edward.

The "AN5276" application note says we should measure the antenna at 1MHz.I don't understand why we couldn't measure it directly at 13.56MHz.

Hi,I'd like to integrate calypso protocol (Calypso Networks Association) in a terminal based on STM32 + ST25R3911.The STM32 will run a SW package which implements Calypso (taken from https://keyple.org/learn/build-your-first-app/cpp-app/).My question: Do I need a Calypso SAM additional to ST25R3911 (or ST25R3911 + SW package is just enough)?Thanks,Aviv

I want my code to pick up a value set in the ioc project file, specifically:<project>.ioc | Pinout & Configuration | Software Packs | AZRTOS(M7) | ThreadX | Core | TX_TIMER_TICKS_PER_SECONDIs this possible? I see I can override this in tx_user.h, but I would rather have "one truth" for this value.Is this possible?

UART2 bootloader is not work.Should I flash a bootloader program to enable usart2 booloader.Which uart has default bootloader program.

When I'm working on configuring devicetree for a new board, adding new nodes and tweaking values, I often run into a un-bootable system. What I would like is that there is a bit more information of what goes wrong.Like now it just quits booting if some node in the references some unitialized hardware. like if vrefbuf perihperal is not activated, and I reference a voltage from there *Crash*.Is there any ways to make the workflow more tolerable?

Hello everybody. I need to share external and software RESET between two different electronic boards. I designed a circuit based on transistors and optocouplers. The soft reset ground the NRST pin, this way I would like to trigger an optocoupler, but I couldn't find information about the current that the CMOS supports. Can I consider it as a common IO? Here are images of the circuit I drew and the information I found. Thanks.

I use this code to switch to bank2 after downloaded fw image in bank2. I have verified that the first address is (stack pointer) is pointing to the SRAM. But still it starts the code in bank1.Is there any example that I can follow?       /* Unlock option bytes */        HAL_FLASH_Unlock();        HAL_FLASH_OB_Unlock();        /* Read option bytes */        HAL_FLASHEx_OBGetConfig(&opb);        /* Modify */        if ((opb.USERConfig & OB_USER_DUALBANK_SWAP_DISABLE) == OB_USER_DUALBANK_SWAP_DISABLE) {                /* Switch to bank 2 */                LOG_INF("Switch to bank 2");                opb.USERConfig = OB_USER_DUALBANK_SWAP_ENABLE;        } else {             &nbs

Hello,I am following a course on Udemy ("Mastering Microcontroller and Embedded Driver Development" if that matters) and I try to set my Nucleo as SPI master.I set up the SPI but the NSS pin does not want to go high when I enable the peripheral.A workaround is to set a pullup on that pin but I don't like the manual idea because as I understood that should happened automatically.I don't want to bloat you with my code but if needed I can share it.In general what I do is:-Setup the USER button as input so when it is pressed to trigger the data send.-Initialize the MOSI, CLK,NSS pins at GPIO alt fun, No pull ups, push pull, speed low(tried all 4 speeds).-Initialize SPI2. BUS=Full duplex, Mode=Master, Speed (tried all), DFF=8, CHA=0,CPOL=0,SSM=0,SSOE=1.This is the lesson's code actuallyAlso other students had the same problem as I saw in comments.I hope some more experience could help!Thank you in advance

Hi, I am working with the Nucleo-F401RE board and I am trying to implement the printf function to work with UART2. I can load and run the example project, but implementing the same code does not work in a separate project.  I have had zero luck getting this work after having read and implementing everything that I can find. I have the following code in the main function taken from the example. I am missing something crucial here and could use some insight. Thanks,D /* USER CODE END PFP */#ifdef __GNUC__ /* With GCC, small printf (option LD Linker->Libraries->Small printf   set to 'Yes') calls __io_putchar() */ #define PUTCHAR_PROTOTYPE int __io_putchar(int ch)#else #define PUTCHAR_PROTOTYPE int fputc(int ch, FILE *f)#endif /* __GNUC__ *//* USER CODE BEGIN 0 */PUTCHAR_PROTOTYPE{ /* Place your implementation of fputc here */ /* e.g. write a character to the EVAL_COM1 and Loop until the end of transmission */

Hello, Is there any tip or reference code to implement WRP? I need to prevent changing original codes and adding any other codes from malicious third parties.I use stm32f303k8 and CubeIDE.I appreciate any help you can provide.

Hi,I have integrated with lwIP and freeRTOS a VNC server on a STM32H757-EVAL.A VNC client works fine and I can see on it the first frame buffer drawn by the application; according to the VNC standard, the server should send a "new tile" (a square of pixel) to re-draw the frame buffer changed (if something happens and change it - i.e. slider, button clicked, etc..).Is there any function or method to understand which pixel (or pixelS) has changed (in term of X and Y coordinates) from the previous frame buffer?In this way, I can recreate a new tile and send it to the VNC client without re-send every time the whole frame buffer using less bandwidth.Thanks for your help.Regards.
