Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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...
Hello, I’m currently working on an application using the STM32G031xx MCU and need to ensure IEC 60730 Class B compliance for safety-critical software. I found the X-CUBE-CLASSB-G0 (v4.0.0) library and have a few questions: Is X-CUBE-CLASSB-G0 v4.0.0...
I want to send and receive data using the USBX library with the STM32U073 as a COM port. Can I use bare metal (without RTOS)?
BackgroundWe have a battery-powered device using:MCU: STM32 (STM32L4series)Modem: Quectel BG95 (cellular)Communication: UART with Idle Line Interrupt (HAL_UARTEx_ReceiveToIdle_IT)Power mode: Device goes to sleep periodically, wakes up to communicate ...
Hi everyone,I'm currently working with the DMA concept on an STM32H7. I'm reading data from an FIFO via SPI. My goal is to trigger the SPI DMA transfer using TIM12 TRGO, but I’m not sure where to start or how to properly configure this connection.I’m...
Spend full week trying to get NOTIFY response during mxwifi_init() Hope that accurately reproduced main steps of demo for Wi-Fi Web Server for the U585 board that is by miracle working Accurately Removed all code related to Web ServerFailed to imple...
Hi everyone, I’m currently working with an STM32H747 and trying to perform SD card write operations using core M4. The SMMC1 peripheral is connected to the D1 domain, which (as far as I understand) means that the M4 core (D2 domain) doesn’t have di...
I am implementing custom CAN bootloaders for H725, G491, and H563. I would like to use the same bootloader across all MCUs.Are the flash interfaces across these MCUs close enough that a common bootloader is feasible? [I haven't compared the reference...
I have setup a Nucleo-F103RB as a USB composite device by (CDC + HID) by modifying a STM32CubeMX CDC project. The device enumerates correctly and everything works initially, however I am encountering a strange bug where if I open a COM port to read ...
Hello,I am trying to get the USB HID working on STM32U073 with ZephyrOS.I took the sample code from https://github.com/zephyrproject-rtos/zephyr/tree/v4.2.0/samples/subsys/usb/hid-mouseAnd tried both the NEXT and legacy USB stack. However, when I boo...
Dear STM32 Advisor, I'll design a system based on Nucleo 64 H533RE. The system will act as USB CDC and USB HID Keyboard at the same time. The idea is when the CDC receive a character, here for example "F" then the Nucleo H533RE will output a high g...
