I fear there is an error in the new Nucleo-U031R8 board. The D13 pin is labeled as the SPI1 SCK pin on the boards' silkscreen. However, the board schematic shows that this is connected to PA5. STM32CubeMX reports pin PA1 as the actual SPI1 SCK pin.Source: https://www.st.com/resource/en/schematic_pack/mb1932-u031r8-b01-schematic.pdfSource: STM32CubeMX configuration starting from the Nucleo-U031R8Tx board. I've confirmed A1 (Connected to PA1) to be the actual SCK pin with both a logic analyzer and functioning SPI sensor (which was not the case with SCK -> D13).  

HI I need to know the pin names for motor controller PWM out  PWM High and PWM LOW i can not directly PWM out function for pins Also need capture control pin details to measure the PWM. As i have to assign these pins for controller

Good morning,I work actualy with the LIS344LH accelererometer and I was informed it will not be available anymore.Do you know any other devices that would substituate it ? I need it for measuring the movement of a tuning fork with a resonnance frequency of 1.8kHz.Thank you everyone :)

Hi all,I realized my custom external loader for STM32CubeProgrammer and it works fine when used from the Programmer GUI.I can program, erase ad read external flash.Now I'd like to use the command line interface but I cannot find how to mass erase the external flash from CLI.If I load a .HEX file for the external flash the affected sectors are erased and programmed perfectly, but issuing the -e all command anly erases the internal flash.Since my .hex file contains only used external flash areas, I'd like to do a mass erase before writing so I'm sure that flash is clean before writing.External mass erase is possible from GUI so I suppose it is also possibel from command line...Any suggestion?Thanks,Davide

Hello ST Community!Please help with resolving issue with WHO_AM_I register!Firmware that I'm using on MKI109V3 board is V3.65.5. 

(mildly off topic) To power the STM32WL5EJC, we need to make a custom board incorporating the charging and protection circuit since 30mAh Li ion cell does not have build-in protection board. Appreciate circuit diagram, for or similar to, the popular Li ion cell charging board using TP4056 and protection chip DW01A.  Many thanks 

Is the STM32WL5JC has TCXO oscillator for the LoRa transceiver?   What is ppm frequency accuracy?I would like to send 20 bytes to maximum distance using maximum spread factor, SF12.  On air time is about 1.2 seconds.  From reading, standard bandwidth seems 125 kHz.  I may have to reduce bandwidth to, says 30 kHz, to increase receiver sensitivity. 1. How is the oscillator frequency tolerance between two boards?  Presumably, I should not reduce bandwidth too narrow toward the freq tolerance limit.  Any idea on a safe value? Twice crystal ppm plus some margin, plus some for sensor at motion (says 3 to 5 miles per hour)?2. The packet tx time is "long" at 1.2 seconds.  Will the oscillator drift within the tx time become significant?  Seem read 'automatic frequency correction/tracking/compensation' some where?  Does this chip has such facility?  Is it turn on "low data rate optimization"?  I can heat up the AC powered base stat

Hi, I have a B-L475E-IOT01A2 board and I would like to implement an USB HID application on it. I use the example project found in the Github repository [1]. The application compiles and the USB device is detected on my computer as an input device. The problem is that upon a USB disconnect, the PC seems to jump to 0x0. When plugging the USB cable in again, the application runs again, but it seems I cannot run any code (in, e.g., the main while loop) after a USB disconnect interrupt while the cable is disconnected.I see this problem both with STM32CubeIDE with ST-Link as well as with SEGGER j-link and Ozone.In Ozone, I can set a breakpoint in the PCD Interrupt Handler for disconnect events (using USB_OTG_GINTSTS_OTGINT), which will trip upon disconnect. If I step through, I can finish HAL_PCD_IRQHandler to get back to OTG_FS_IRQHandler. As far as I can see, the PC clears to 0x0 after the POP {R7, PC} instruction which returns from the exception handler "OTG_FS_IRQHandler".It can also be

Hi Looking at the PD55015 it has a declared output power of 15W. The evaluation board STEVAL-TDR016V1 on the other hand is rated at 30W output power? How can the evaluation boar be rated at twice the output power of the device it is demonstrating without running multiple devices in parallel? @Peter BENSCH?   Which is the proper group and label for RF power amplifiers/transistors? I found no match

HelloLast week I received the ST25RU3993-HPEV devlopment kit. I have already downloaded the SDK and tried it out. Unfortunately, I have not found any information on how to write firmware for the board myself. Is that even possible? Or is there a way to communicate with the board via UART using AT commands, for example?

I am doing a USB HID project and have followed a lot of the setting up of this YouTube video. I have set it up to send a string when I press a button. Using Device Monitoring Studio, I can see that when the device is plugged in, it reads the descriptor, checks the PID and VID and responds to the button press and receives the string.If I leave it for roughly 5 seconds (DMS measured 5.0087 & 5.0013 seconds) then it goes into a suspended state. Once this has happened, any button presses are ignored, and I am unable to get the USB to respond to anything, unless I unplug it and plug it in again. If I do this, it works fine until it is left for another 5 seconds. I have even removed the code inside the HAL_PCD_SuspendCallback in usbd_conf.c to try and stop it getting suspended but it still goes unresponsive. I'm at a bit of a loss as to what to do now!

I'm working on a state machine for a console application, and I would like to use std::strings in C++, as they are much nicer to work with than C-style strings.Including the string library does not result in errors, but when I call string objects in the code I start to get errors.  Here's an example of the code I am using://const char* output; //No errors in c-style strings std::string(output); //Compiles, but results in linker error switch(mState) { case MAIN_STATE: output = "\r\nmain->"; break; case CAN_STATE: output = "\r\ncan->"; break; case UART_STATE: output = "\r\nuart->"; break; case GPIO_STATE: output = "\r\ngpio->"; break; default: output = "\r\nMAIN->"; break; } //Print(output); //No errors with C-style Strings Print(output.c_str()); //Compiles, but results in linker error As I indicated in the code comments, any time I call a function from the <string> library, I get the following linker error:07:41:57 **** Increment

During compilation with IAR, I ran into an error. Please refer to the picture below. Upon checking the source size via the map file, it appears as follows: After examining the RAM size, it seems that the capacity of SRAM1 is less than 12K. I believe this shouldn't cause a compilation error. What could be the cause of the compilation error? 

i'm using stm32c011f4u6 mcu's DK(stm32c0116dk), and i generate the file as mdk-arm and it's running with keil5.i tried erase to test the flash memory, but it doesn't work. i even used the SDK example file, and i get the same error. Below is the main.c file. /* USER CODE BEGIN Header *//********************************************************************************* @file FLASH/FLASH_EraseProgram/Src/main.c* @author MCD Application Team* @brief This example provides a description of how to erase and program the* STM32C0xx FLASH.******************************************************************************* @attention** Copyright (c) 2022 STMicroelectronics.* All rights reserved.** This software is licensed under terms that can be found in the LICENSE file* in the root directory of this software component.* If no LICENSE file comes with this software, it is provided AS-IS.********************************************************************************//* USER CODE END Header *

I'm tring implement IAP on NUCLEO-H745ZI-Q.So. I seen STM32h743-eval IAP Example.But I have two bank and two core for cm7 and cm4.I don't know how to implement the bootloader.And should I create and transfer bin files for cm4 and cm7 respectively?

I have the following questions and need help:1. Can this transistor be used at a frequency of 900kHz? Can it only be used in frequency bands above 1MHz?2. The data sheet provides a test circuit under 30MHz conditions. We do not fully understand the functions and principles of the FB2 and T2 components. Can you explain it to us? We guess that the function of this component should be for impedance conversion. Can the FB2 and T2 components be replaced with a simple and easy-to-understand transformer impedance conversion form (FT-43 core) like the previous stage?3. Is the output of the 30MHz test circuit given by the data sheet sine wave? L1, L2 should play a low-pass filter, but I see its winding method did not understand, can you explain?4. We want to imitate the 30MHz test circuit and apply it directly to the production environment. Are there any other issues worth noting during this process?

Hi, everybody. I am repairing a machine that uses the IC TH2008-01 from STMicroelectronics, but I need the data sheet. Can you please send it to me? Thank you.

I'm looking for some instructions on how to develop firmware for the Portenta H7 using the Portenta Breakout Board with the STM32CubeIDE. Before ST Microelectronics comes back and says they can't help because the H7 is not their product, that is unacceptable. If this is the case, it may be time to look at other vendors (Nvidia). STM can only benefit from helping developers write software for the Portenta H7 using the STM32 suite of development tools.

Posted on September 13, 2017 at 08:24If I configure one GPIO pin to output. Is there a function in HAL to read back the current output status of it?

I'm using a custom board with the STM32WL5MOC. I've noticed that the last three 32-bit words of the OTP have been written to the values: FF FF FF FF FE FF FF FF 02 00 10 38 D1 DB AF 46This makes the OTP 16 bytes shorter. Is this intentional, or is it a bug? 

I am pretty new to STM32CubeIDE and am trying to build the example project for I3C_Controller_Direct_Command_DMA using the STM32Cube_FW_H5_V1.2.0>Projects>NUCLEO-H563ZI>Examples>I3C>I3C_Controller_Direct_Command_DMA project example and following this example document.Following the document, i needed to have this code in the desc_target1.h so i started there.At first, this header was not in my project, or i couldn't access it, so i imported it manually which fixed that problem and this is the code that was in it by default. The problem I'm facing is the errors I am getting. "unknown type name 'TargetDesc_TypeDef'" "'DEVICE_ID1' undeclared here (not in a function)" "excess elements in scalar initializer" etc.Am i not including this header file correctly? Am i missing more files for my project? Am i not following the example correctly? Please if anyone has any insight i would greatly appreciate it.

Hello everybody, in the latest CubeMX ver 6.11.0 I found that it's possible to generate a CMake project. What are the steps to run the build of the code from Windows shell or VS Code ? Is there a tutorial ? If I open the CMake project from CubeIde (v 1.15.0) then I'm not able to build the code, the Build command is disabled. Instead, if I follow the doc AN5952 I'm able to build the code also from CubeIde, it seems that the CMake generated files are different if I generate the CMake project files from scratch by using the AN5952 and if I generate the CMake project files from CubeMX 6.11.0   Thanks   Max    

Hello,According to the datasheet PB7 can be used as  ADC_IN11.Is this an error in datasheet? ADC_IN11 is already used by PB10 and cubeMX doesn't seem to allow me to use PB7 or to remap this pin. How can I use ADC_IN11 on pin PB7 as mentioned in datasheet?Thanks
