Solved

Hello guys, how are you?​I'm investigating some .bss overflows i'm facing and i ended up on some weird question. Linker file for STM32WB generated by CubeMX is as follows:RAM1 (xrw) : ORIGIN = 0x20000008, LENGTH = 0x2FFF8RAM_SHARED (xrw) : ORIGIN = 0x20030000, LENGTH = 10K​The sum of this two portions is around ~206K. The STM32WB datasheet says that this MCU has 256K of S-RAM, so.. where are the other 50K of RAM?:face_with_tears_of_joy:

Hi,I was wondering what the TouchGFX porting process is like for development across different MCUs.I'm thinking of starting development for a GUI on an STM32 Discovery Board, and then when the actual hardware gets produced, switch over to developing on that. I was wondering what the porting processes for that would entail.It seems like you can easily port over a TouchGFX version on the same MCU. https://support.touchgfx.com/4.20/docs/miscellaneous/updating-to-a-new-touchgfx-versionBut I was wondering if there was a similar process across different MCUs other than just re-generating the MCU specific code and then copy and pasting the user code into the new project.Thanks!

​Hello, I am developing Arduino using CR95HF.I succeeded in reading the Tag ID using Cr95HFIf you read it with mifareCard 1K, you can read the Tag ID, but it does not read/write the memory sector.I need to go through the authentication method to read, but I would appreciate it if you could tell me how to use it because there is no description. Can you provide the data informally?Thank you.

I'm working on a new IOT device. I'm using your BLUENRG-232N device with STM32L496AGI6 microcontroller, and I'm using your STMicroelectronics.X-CUBE-BLE2 version 3.2.2 stack for the firmware and the application. but unfortunately the mcu goes into the Infinite_Loop: during the call of the MX_BlueNRG_2_Init function. Find attached the demo_project and schematic.

Hi, do the STM32WB support Bluetooth 5.2 LE isochronous channels?Thanks!

I am looking for example code for PFC and voltage source inverter control.I was scanning through the example list from IDE but could not find any.Could anyone direct me to them if they do exist?

Hello guys,I've been researching over the internet and in this forum about creating a composite device on STM32WB5M. I need to create a device that has a HID and a mass storage over the same USB. I saw some old posts saying it was not possible but at the same time i saw another posts saying it is possible in some ST microcontrollers. I really would prefer to do that using ST Library, or modifying ST Library if needed. Could anyone give me any hint, examples or a user manual of how i could begin this development?

I'm currently using STM32l431cc and I want double or triple the size of flash, keeping the pinout constant. I want to order large number of pieces in the future, so i looked in the table and found that one version stm32l451ce is present. So my question, is stm32l451ce can be a perfect replacement for stm32l431cc, just with bigger flash?I just need some confirmation before doing this..Thanks in advance. regards,vmere.

I'm designing a power line for the STM32WB55 microcontroller.I'm checking the power system on the Nucleo-68 board but I found that the microcontroller cannot send a Bluetooth signal if I connect Vsmps only when booting the microcontroller.I also found that it successfully work after removing VDD_MCU and VRF after finishing booting.Is it correct? It would mean I have to supply power to VDD also.I also found that connecting VRF makes Bluetooth signal better.

Hi,i try to write the OTP area lock bytes using the ST-LINK/V2 programmer with the ST STM_Programmer_CLI tool included in the STM32CubeProgrammer software package.I can successfully write to the OTP area blocks using the -w32 command but if i try to also write the according Lock byte it will fail with the following error message:Command: STM32_Programmer_CLI.exe -c port=SWD -w32 0x1FFF7AC 0xFFFFFF00Error: Failed to download data!If it's a Flash memory, it may be not erased or protectedAny idea why the write fails for the Lock bytes while OTP blocks are successfully written ?

I am currently working on a motor control project development using STSPIN32F0251.Six-step control using HALL sensor, 48V power supply, working phase current is 11A. Then now running at 10A, the smartSD protection with the built-in gate drive is triggered, and the built-in FAULT pin outputs a low level. But I have grounded CIN directly, and observed VCC with an oscilloscope, there is no voltage abrupt change in VCC below VULO.So I would like to ask what else will trigger the smartSD protection and cause the FAULT pin to output a low level, thank you!

Hi all, I'm trying to write a simple code to read a Tag NFC type 2. I have a EVK NUCLEO stm32F446 and X-nucleo-NFC06A1, I want connet they with I2C. and write a simple code to wake up st25 when I send a high signal and read eeprom of tag and show this information via UART.

Due to hardware limitations, I must run MotorControl Workbench through the command line. However, running the executable WB_Console.exe fails to open valid projects.Command issued:"C:\Program Files (x86)\STMicroelectronics\MC_SDK_5.Y.4\Utilities\PC_Software\STMCWB\WB_Console.exe" -f example.stmcx -generate -QThis command ideally begins generation without the GUI. However, I immediately get this error:The project was created with a legacy Workbench release 0.0.0. Please use that version to load the project. Generation with error.Given that the example.stmcx is a perfectly valid file (and functions on other hardware), this error is problematic. However, the bigger problem is that the generation will succeed occasionally. I cannot isolate why and have run several tests, including shutting down the system, introducing new (both valid and invalid) files, resetting the software, closing the console.Regards,DS

Hi,​ I have tried many times to get a trace using STM32CubeMonitor-UCPD 1.2.0 with my board without success. I have tried with both RTOS and without. The USAR1 is connected to an FTDI usb serial cable but the board doesn't show up In the monitor. I have noticed that USBPD_PE_StateMachine_SRC returns -1 which prevents it from ever being called again since the return value is used as a waiting time. Find attached my main.c (initialization of the board and peripherals)

Hi,I'm trying to configure a project in STM32CubeIDE with EMW3080 Wi-Fi driver following an example form STM32CubeU5 and Introduction to NETXDUO article. I add NetXDuo files for Wi-Fi driver and configure mx_wifi_conf.h file but I get the following console errors:make: *** [Middlewares/ST/netxduo/common/drivers/wifi/mxchip/subdir.mk:25: Middlewares/ST/netxduo/common/drivers/wifi/mxchip/nx_driver_framework.o] Error 1 make: *** Waiting for unfinished jobs....And errors like this on nx_driver_framework.c file:'NX_DRIVER_ERROR' undeclared (first use in this function); did you mean 'NX_CALLER_ERROR'?but NX_DRIVER_ERROR is defined in nx_driver_framework.h file in the same path of nx_driver_framework.c file.Thanks

For performing the conversion do I just have to convert degrees to millidegrees?Because this conversion does not output a perfectly comparable result.Racelogic IMU datasheet: Overview (racelogic.co.uk)
