SPC58EC has one Interrupt Controller which supports two processors. You can give different vector tables for each core. Let's say two cores are active and one external interrupt (ADC, Timer) happened, what will be the process after this? Which core will run the interrupt handler? Thanks in advance.

Hi everyone,I'm trying to convert our IoT Sigfox sensor from EFM32 to STM32 architecture.As a beguinner on STM32, I'm using an LSM100A eval board based on STM32WLE5CC.Can anybody explain me how to create a simple Sigfox project ? I just want to send a simple Sigfox message.I try to start from the PushButton skeleton available on project configuration but there is alway something missing in the generated source code. First build give errors like these :../Core/Src/timer_if.c:337:51: error: 'RTC_N_PREDIV_S' undeclared (first use in this function); did you mean 'RTC_PRER_PREDIV_S'?../Core/Src/timer_if.c:415:30: error: 'RTC_PREDIV_S' undeclared (first use in this function); did you mean 'RCC_PLLDIV_3'?Any help would be greatly appreciated !Thanks,Johann

The STM32F401xD has 384Kbytes FLASH and the STM32F401xE has 512Kbytes FLASH.Is there a mistake in the reference manual?3.3 Embedded Flash memory in STM32F401xB/C and STM32F401xD/EAccording to the manual STM32F401xD/E have the same number of sectors. I would expect that only STM32F401xE has an additional sector 7.

Hi all,In STM32H7A3 reference manual section 27.4.33 internal temperature sensor equation Temperature in °C = TS_CAL2_TEMP - TS_CAL1_TEMP / TS_CAL2 - TS_CAL1*( TS_DATA - TS_CAL1) + TS_CAL1in Last TS_CAL1 i have doubt because all other H7 family like (STM32H742,STM32H745) datasheet show like below equation Temperature in °C = 110 °C 30 °C / TS_CAL2 -TS_CAL1 * ( TS_DATA TS_CAL1) + 30 °C.so when i put TS_CAL1 then it give output higher value because in TS_CAL1 = 12344 value so overall output value is 12389 °C something.but when i put +30 °C at the last then its give reasonable temperature value (30 to 35°C)so i need to confirm is that any written mistake in datasheet or i doing wrong anything please help me. Any help is very much appreciated! thank you.

Hello, i would like to integrate ​st25dv04k nfc dynamic tag to my pcb design, my question is: could i use it without any configuration or initialization?As I'm planning to not connect it to a i2c device.​​If yes, should i connect the harvesting power pin to VCC?​​The component datasheet:https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.st.com/resource/en/datasheet/st25dv04k.pdf&ved=2ahUKEwjf6dmlv-P2AhXQ-KQKHbHmAIwQFnoECAQQAQ&usg=AOvVaw1VPzvL4lIjIgv1-XrpOp-J​

Hi,so a few months ago I wrote a program to read values from LIS3DSH sensor. It was working good until last week Z axis stopped working, and this week Y axis also. It always sends back 0x8080 values, while X axis is still working great. I have a custom PCB board with STM32F407VG and LIS3DSH (and more :) ) and this problem only occures on this board - when I put the same program to STM32F407VG - DISC board it works great, thats why I don't think there is a problem with my program or my SPI configuration. So, I decided to change LIS3DSH to a new one (I can do that because it's changeable on my board). The problem is that new LIS always responds 0xFF to whatever I send to him. To be fair with you, I don't remember now if I had to anything special at the first start up of the old LIS3DSH, but the one doesnt wont to work with the same program that DISC works.Does anyone had this kind of problem? Or maybe, there is a special config to put at the first start up (but I cant find it)?Thank you

My UART example works very well.  But, I want to do with the UART interrupt.  Currently it does not work because it always jumps to an infinite loop in the start up assembly code.Infinite_Loop:  // startup_stm32f411retx.s b Infinite_LoopHere is my source code. It works great without USART receive interrupt enabled.  USART2_IRQHandler is never executed. I have put a breakpoint inside it. Instead, it always jumps to the Infinit_loop line. What did I do wrong? Why your HAL / LL examples work?  I looked into the HAL / LL code.  It is very similar to my source code.Thank you for any help you can provide.Michael//#include "my_stm32f4_uart_driver.h" // No NVIC_SetPriority, NVIC_EnableIRQ#include <ctype.h>#include "string.h"#include "stm32f4xx.h" // I need to use this library for NVIC_SetPriority, NVIC_EnableIRQint main(void){RCC->AHB1ENR |= 1; //Enable GPIOA clockRC

I just created a project in STMCubeIDE for STM32MP157A-DK1 and am trying to run MCU debugging in ENGINEERING MODE and PRODUCTION MODE. I use an ST-LINK wire and an Ethernet Over USB connection. SSH and the UART command line work well. In engineering mode, I get the hardware breakpoints error. In production mode, all breakpoints that are set to an infinite loop do not work...this is very strange. What did I miss?

Hi,here I am trying to Communicate with two x-NUCLEO-NFC05A1 Board For P2P Communication.STM32G071RB Nucleo Kit Board using for this Main MCU. Getting the demo.c file from this below LinkConnect two X-NUCLEO-NFC05A1 with Peer to Peer (p2p) connection. (st.com)using this Example demo.c. i can read Passive NFCA type tags . But Not to see any NFCF Passive P2P device found.Here our application is data File Transfer from one Controller to Another by NFC P2P Mode.  Pls Give the guidance how to data Exchange from one to another.?

Hello. I work in CubeIDE 1.9.0 with the stm32f429i-disco device. The problem arises about firmware and debugging. I made a simple example to check. During debugging, strange behavior was noticed when executing HAL_Delay (line 95). When executing Step Over on this line, Debug Current Instruction Pointer remains on the same line. If you put a breakpoint on this line and Resume, the LEDs are reset to the initial (off) after each iteration, although they should change their state every 250 ms. Previously, I worked with bootloader on this board. I also noticed that the user USB LED lights up when power is applied in the absence of firmware in the memory of the microcontroller. Keil faced the same problems that were described above. Tell me, please, can this be the result of mechanical damage to the board or is it something else and how to fix it?/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main

Hello everyone,I am trying to upload a program via the Cube Programmer to my STM32f647g_Disco board.When using CubeIDE it works flawlessly, but when I try to flash the HEX files with CubeProgrammer, it is showing the following message: " 18:10:01 : Error: Data mismatch found at address 0x900002F3 (byte = 0x00 instead of 0x04) 18:10:01 : Error: Download verification failed"I think it does not save the new software to the external flash memory of the board.Do you know a workaround for this?In the appendix there are two logs, one from CubeIDE (with functioning flashing), one from cubeProgrammer.Until now, I was using the HEX file that get´s generated in (ProjectName\CubeIDE\Debux\ProjectName.HEX)Do I have to use a different one, or a second one for the external memory?I also noticed that the BIN File (in the same folder directory) has more than two GB. IS that normal?Thanks for the Help!

I'm using the Nucleo-32 on another project and have found the schematics in UM1956 helpful in certain debugging scenarios, as well as a kind of reference design to help me get started on my own board design.

As noted on the documentation the VL53L5CX could integrate a microcontroller with an internal oscillator/PLL clock source. This could have a high frequency value in order to handle the ns-scale timing of the FlightSense technology and the histograms processing.I am investigating the EMI spectrum of a product integrating a VL53L5CX and I should consider all the possible noise contributions.Thank you

So the question is: Whats the best way to import an example project into CUBEIDE and have access to the CUBEMX view?Background:I want to use one of the STM32 examples with CUBEIDE. Specifically the example is "LwIP_HTTP_Server_Netconn_RTOS". Anyways I am able to import the project into cube IDE and run the project in the debugger with a couple of really minor fixes. This does not produce the IOC file that can be opened in the CUBEMX view.Thanks!!

We've just changed the way our system is powered: Previously the accelerometer was powered from a 1.8V regulator, now it's powered directly from a 3V coin cell (schematic part attached).With the change, we have started to observe a strange ramping which is visible from about 2V upwards and increases with an increase in VDD. Attached is an image of the current ramping, with VDD set to approx 2.9V. The larger thin spikes belong to a BLE module, the very tiny spikes are all I would expect to see of the accelerometer in operation - in fact that is the case when running at 1.8V.The accelerometer is configured to capture in FIFO mode, the gyro is off. The IRQ is used to notify FIFO events and to flush the buffer. Same ramp is visible, regardless of power mode (ultra low, normal, high-perf). We are only ever capturing at 12.5Hz. No extended functionality is enabled (motion event, etc). We use SPI Mode 1 to communicate with the device, both IRQ pins are connected to our Micro. Is this expected

I've just tried on an 'L031 - after writing LSEDRV to 0b00 (using debugger), I can rewrite it freely to any other value, and the oscillator's behaviour follows the value written.Can ST please comment.JW
