Solved

I am configuring to support Stop mode 2 in the stm32_wpan configuration section in the STM32CubeMX.The following lines are generated in stm32_lpm_if.cSYSTEM_DEBUG_SIGNAL_SET(LOW_POWER_STOP2_MODE_ENTER); SYSTEM_DEBUG_SIGNAL_SET(LOW_POWER_STOP2_MODE_ACTIVE); SYSTEM_DEBUG_SIGNAL_SET(LOW_POWER_STOP2_MODE_EXIT);However, the definitions of LOW_POWER_STOP2_MODE_ENTER, LOW_POWER_STOP2_MODE_ACTIVE and LOW_POWER_STOP2_MODE_EXIT don't get generated, which are causing undefined compilation errors.I checked the expected types for these definitions, and see that these should be defined as part of the system_debug_signal_t enum inside debug_signals.h. I have tried looking for additional configurations that might generate the missing definitions but I haven't had any success so far.What should I look into or how can I generate these missing definitions? I could try to manually add these definitions to system_debug_signal_t. but then any time I re-generate with new configurations it

Dear forumI need to update a board that uses BMO055 9 axis IMU and I need to know what is the preferred ST solution that best fit this obsoleted part.I need the 3 axis gyro + 3axis accelerometer + 3 axis magnetometerIf there is a single chip solution its okay, but a dual chip solution can work as well. Thanks in advanceIgnacio

hello, I'm programming a UWB DWM1001 on stm32cubeide with a h755zi-q board.I would need the libraries for this device, do you happen to know where I can find them?

Hi all, Previously, I've been adding all paths with the used header files in the Project->Properties->C/C++ Build->Settings->MCU GCC Compiler->Include paths->Include paths (-I), like this:It has been working pretty well, until it just stopped. The last thing that I've tried to add is "${workspace_loc:/${ProjName}/Firmware/MCU/Processor/FPU/FPU_Reg}" path and the compiler doesn't see header files stored there anymore. So, if I write #include "Cortex_M4_FPU_Reg.h" in source files, the build console throws out this error:but when I write #include <FPU/FPU_Reg/Cortex_M4_FPU_Reg.h>, everything is ok.Does anyone know why Include paths (-I) worked previously, but now it stopped accepting new paths?

Hello, please, can I put the power antenna configuration to the maximum 8dBm? and how? thanks

I used the N6 to run the mobilenet_v1_0.25_224_fft_int8.tflite, input is correctly put into the input buffer, memory map activated, NPU RAM enabled, AXICACHE enabled, everything seems to be right, the input I also test the input inside the PC in python, and the model can output things right.I dot know why, but in some steps it either jumps in to HardFault_Handler (if I directly start the debugging process without any break point)or runs everything right (using some breakpoints inside the runtime and network.c) but outputs are all Nansdo you have any ideas how I can fix them ?

Hi,I have designed a custom board using STM32G431CB and TCPP03. I am trying to make as a sink device. I followed this video : https://youtu.be/cbdFHmMOMwk?si=GqcDTJeDxTsrFDiGI have successfully generated and compiled the code. Also, i enabled the GUI interface and TRACE. I am able to get the trace messages in STM32CubeMonUCPD. But unable to see the GUI interface board port, I tried refreshing it several times but no luck . Please help.Thanks in advance.

I try to get the CAN working. But currently I'm not sure what I'm missing.I use the STM32CubeIDE v1.18.0. The boards I use is own hardware with SN65HVD232.The hardware seems to work well. on the picture you see the screenshot from my oscilloscope, CANTX, CANRX, CANL, CANH after calling:HAL_CAN_AddTxMessage(&hcan1, &TxHeader, &TxData[0], &TxMailbox)The complete code is here:/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2025 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. * ***************************************************************************

Hello Anyone did ever you use the MC34063ACD-TR for to power on a "MCU" at 3.3V? From datasheet it seems it needs change R1 and R2 for to obtain the goal but the figure 15 shows until 5V so..I ask you if i can use it for my application. My application is to convert  from 24V to 3.3V.

Hi there!I've created a custom STM32F411CEU6 Board with external HSE und LSE. While the HSE works when running my user program, the Bootloader hangs within boot phase (i think).When starting bootloader, BOOT0=1 und BOOT1=0. I powered direcly on VDD, no USB. I received no answer on both uarts after sending 0x7F. I also can't connect via stmcubeprogrammer. Only can only connect with stlinkv2.I think it may be a hardware issue, but I can't find a solution.Crystal 25Mhz: https://atta.szlcsc.com/upload/public/pdf/source/20240329/19D5F850207469550BEB00D7DFEDBC7A.pdfLSE:https://atta.szlcsc.com/upload/public/pdf/source/20240418/0E0FF5F0356BA3753F616001439D1416.pdf 

 I'm using the STM32H753ZI Nucleo board with USB_OTG_FS communication,and I have enabled VBUS_SENSING. I would like to detect when the physical connection is lost,but I am not sure how to do it.Could you kindly provide any reference materials or guidance on the best approach?

Hi,I am trying to minimise the error between the I2S sampling rate.You can do this pretty well in the STM32F4 because it has an independent I2SPLL (0.02% error between target sampling rate and actual rate is excellent), this is done by changing the PLLI2S N and R values. However, I do not understand why the 48kHz sample rate needs "I2S clocks (MHz)" to be around 49 MHz. Can someone explain that?

I'm new to fiddling with MCUs, so I'm looking for some advice, I'm working on a project for my class and I'm trying to emulate a keyboard using the nucleo-F103rb. I have my code written out, I have a usb cable with D+ Connected to PA12 and D- to PA11, GND to GND and VCC to E5V all within CN5. Despite having all the headers in place, my computer doesn't detect any connection whatsoever. If anyone could suggest anything that may help it'd be really appreciated. 

Hello everyone, I tried to put Canopen node for stm32 into operation. I used the standard pinning from STMCubeIde, i.e. pa 11 and 12. But this does not seem to work. void FDCAN1_IT1_IRQHandler(void) { /* USER CODE BEGIN FDCAN1_IT1_IRQn 0 */ /* USER CODE END FDCAN1_IT1_IRQn 0 */ HAL_FDCAN_IRQHandler(&hfdcan1); is not called. Is something known here? Solution was to change the pins to PB9 and PB8. Now the function was called and the stack ran. Is there a workaround to use pa11 and 12 anyway ? Thanks for your support.

How can I generate the sfu_se_mpu.s file for the STM32H753ZI and STM32H733 controllers in SBSFU? 

Hello,I went through all the SWO related topics, and it was a bit confusing for me to get it running, so I summarized the steps to have it working on a Nucleo H755.In my project I have the main clock set at 400MHz, Timer2 running at 1Hz and Debug set as "Trace Asyncronous Sw"In my main.c I have added just this:    /* USER CODE BEGIN 2 */ #define SWO_BASE (0x5C003000UL) #define SWTF_BASE (0x5C004000UL) uint32_t SWOSpeed = 2000000; // [Hz] we have 2 Mbps SWO speed in ST-Link SWV viewer uint32_t SWOPrescaler = (SystemCoreClock / SWOSpeed) - 1; /* divider value */ //enable debug clocks DBGMCU->CR = 0x00700000; //enable debug clocks //UNLOCK FUNNEL //SWTF->LAR unlock *((__IO uint32_t *)(SWTF_BASE + 0xFB0)) = 0xC5ACCE55; //unlock SWTF //SWO->LAR unlock *((uint32_t *)(SWO_BASE + 0xFB0)) = 0xC5ACCE55; //unlock SWO //SWO divider setting //This divider value (0x000000C7) corresponds to 400Mhz core clock //SWO->CODR = PRESCALER[12:0] *((__IO uint32_t *

@Tesla DeLorean Hello,It looks like the https://github.com/cturvey (I believe it is user's Tesla Delorean's) is gone? I have tried to access it yesterday and today and I am getting a page not found error. Any ideas as to why?Thanks. 

Hello Everyone,We have a requirement to flash firmware from One STM32G0B1 MCU1 to Second STM32G0B1 MCU2 via UART.The STM32_Programmer_CLI will be connected to MCU1 via UART. The MCU1 and MCU2 will be connected together via a different UART for flashing. The MCU1 should act as a mediator between STM32 Programmer and MCU2 for flashing.Is it possible to achieve the above requirement? If It is possible, could anyone share the reference documents or reference software for the same.We really appreciate your support. Thanks in Advance,Best Regards,Naveen

Hi,I'm currently working on a project using multiple B-WB1M-WPAN devices:one acts as BLE Central;the others act as BLE Peripherals.I'm using the STM32_WPAN software package in CubeMX 6.14.My question is: how do I create a Central that is able to interact with Custom services and Characteristics defined on my peripherals?I've already started using the Server profile "Custom Template" on the Peripheral devices; for the Central (Client profile), CubeMX forces me to use the "Custom P2P Client", and both CubeMX and the code don't allow for a great deal of customization.Thank you!

I'm trying to interface the STM32F446RET6 with M95P32-IXCST/EF, a QuadSPI EEPROM. For the 64 pin STM32F446RET6 pin PB2 (pin 28) is used both as BOOT1 and QUADSPI_CLKI don't see any other pins that can be used as QUADSPI_CLK for the 64 pin package. Is there a way to interface with the EEPROM?

Hi, I am searching for any documentation or tutorial on how to use debug tools i.e FreeRTOS, SWV etc. Thanks & Regards, YashJ    

Currently I am just trying to share some data between cores, and right now I'm just trying to send a constant value to confirm operation.I have this code located in a file called share.h,typedef struct {   // shared data goes here   int16_t data;   }shared_data_t;and then I havevolatile shared_data_t * const shared_data = (shared_data_t *)0x30040000;saved in each core's main.c file.The location is SRAM3 and according to the RM this is an optimal place to share values. It updates properly in M7, but when I check the struct in M4 it's not the same value. When googling, this was the number 1 answer, the second was the linker. I don't know where to begin with the linker, so if that is the option is there any good guides? Thank you for reading this

Started using PA2 pin as a ADC input and found that the input voltage get corrupted with LSCO output. Happens not always, but very often. Powering board down and up sometimes fixes the problem, sometimes not.The LSCO output enable control bit LSCOEN is 0. Calling HAL_RCCEx_DisableLSCO() doesn't help.Thanks,George

I'm developing an app that writes and reads settings from an STM32 over NFC. I can write settings to the ST25DV mailbox and poll the RF_PUT_MSG register to detect when data has been written. Which register should I poll to know if the app has requested to read data?
