Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Dear STMicroelectronics Support Team,I previously submitted a request on [ Auguest 26, 2025] (case #[00242096]) and have not received a reply.I am evaluating STM32 MCUs for an LwM2M client implementation and need clarification on ST’s official suppor...
HiI have implemented TCP/IP with LWIP, but after enabling the freeRTOS, I'm facing lot of issues, ping is not happening, flash overflow errors , internal flash is very less need to use external flash(how to configure?). Mainly I need to enable freeRT...
I'm already achieved a USBX-MSC class, and also a FileX in MCU local.I know that using two file systems at the same time is not recommended, but still have some questions. 1. I implement the ux_deveice_msc.c as followed. Use PC-Windows to create a f...
To get my first sensor project done and after selecting my board, I enabled I2C1 which triggered pins PB6 and PB7 as shown below: Then used code below (in main.c) with the purpose that the LED is on when the temperature is higher than 40 degrees and ...
I'm using the STM32F401RE in a new design and trying connect the USB CDC device interface to FreeRTOS_CLI. I modified its _write function to call CDC_Transmit_FS, but I don't see a received data callback where I can add a xTaskNotifyFromISRfor to sen...

Hello,I am developing an embedded project using the STM32H7 microcontroller, integrating FreeRTOS, FatFs file system, USB mass storage device (USB flash drive) functionality, SD card reading/writing,UART communication, and ADC sampling. My system use...
Hello there, I'm using a STM32G431KBU and programming it using STM32 Cube IDE.There are 2 pins, PB4 and PB6, both digital inputs, I'm having problem with. On both, I apply 5V with a 10K pull-up resistor, while the MCU is working is at 3V3, this shoul...
Hello ST Community,I'm working on an STM32N6570-DK project where I've merged two example codes from the STM32CubeN6 repository:1 . DCMIPP_ContinuousModehttps://github.com/STMicroelectronics/STM32CubeN6/tree/main/Projects/STM32N6570-DK/Applications/DC...
Hi, just looking to learn the best way to do this. We're aiming to create a system for STM32H7R/S where the bootloader acts as USB MSC device to store a number of different app binaries to a permanently-mounted SD card. At system restart, the booload...
