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...
im looking in the main.h file for this example and wondering where __BUFFER__ is defined thats used in this line #define COUNTOF(__BUFFER__) (sizeof(__BUFFER__) / sizeof(*(__BUFFER__))) thanks for the help
TL;DR - adding USBX and the USB CDC device class to my STM32U5 TouchGFX project causes it to fail during initialization, because the default memory settings are woefully inadequate.I have a TouchGFX project running on an STM32U5G9J-DK2 using ThreadX....
Hi all,I'm currently working on a project using a STM32H753 in combination with the Azure RTOS UsbX to create a composite class USB device (CDC ACM + MSC). As a starting point for the MSC support, I'm using this STM github example:https://github.com/...
Hi,I am not able to output per I2S properly.1. I changed from a properly working driver for STM32F407 to this STM32H7A3VGTI had to learn, that the master clock is different as for the 407; here is always running (?) and the DMA did not work properly ...
Hi all,I’m testing MP3 playback on a Nucleo-WB55RG.Setup:SD card via FATFSHelix MP3 decoder (libhelix-mp3)PCM out via SAI1_A (I²S) → external DACDMA in circular mode, 2× half-buffer callbacksWhat works:A test sine wave buffer played via SAI+DMA works...
I'm a USB newbie and am trying to use the STM32F411CEU6 as a USB mic. I'm currently using FreeRTOS (cmsisV1) and the Cubemax USB library. My device currently enumerates normally, but when the host sends a URB_ISOCHRONOUS_IN request, my MCU won't hand...
I’m encountering an issue with XSPI1 in my application. I boot the application via XSPI2 in an LRUN configuration, and this part works perfectly. However, within the application, I need to use XSPI1 to write data to a different flash.During MX_XSPI1...
Hello,I am trying to set up a UPD communication with a nucleo-H755ZI-Q board.Now I have the effect, that the lwip stack sends out an arp request for its own IP address.I double-checked the IP address and destination address to make sure they were co...
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...
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 ...
