From a USB specification, a USB device should use VBUS sensing detection: When a host connection is detected by the device, the device connects the pull-up resistor either to D+ or to the D- data signal. This allows the host to detect device presenc...
Introduction Modern processors often make speculative accesses to improve performance. In simple terms, the CPU may start reading instructions or data before it is certain they will be needed. This helps reduce delays and keeps the system running eff...
Introduction This article shows how to build a USB Power Delivery sink application on STM32 using the X-NUCLEO-SNK1M1 shield and the NUCLEO-G0B1RE board, in a bare metal cooperative superloop.The example uses the STM32 USB PD middleware and does not ...

Introduction The STM32H5 microcontroller family integrates hardware HASH peripheral capable of computing MD5, SHA-1, SHA-224, and SHA-256 digests, which can be efficiently supplied with data using DMA. In many real-world applications, input data is n...
Summary This article is an introduction to STM32 MCU development through the VS Code IDE using the updated STM32 Visual Studio Code extension v2.0.0 or newer. In this article, we cover the following: Downloading the updated VS Code ExtensionCreating ...
Introduction When STM32 AES encryption or decryption output doesn't match the expected test vector, the instinct is to immediately question the key, mode, or algorithm. In many cases, the real issue is more simple: the bytes are correct in memory, bu...
This article presents estimated lifetime usage for STM32H7RS series microcontrollers. These estimates are qualified based on the product mission profile, which defines the available lifetime of the product under a specific set of conditions. These c...
Introduction This article describes, in a practical and end-to-end manner, how to create and run a minimal AES-GCM example using DMA on an STM32C5 device configured using STM32CubeMX2. The goal is to provide the source code and document the full wor...
Problem Backup SRAM or normal SRAM content is not preserved after reset or wake up from standby. After a reset, the last few bytes written are not kept. Solution This issue appears on STM32 devices that have ECC (Error Code Correction) on internal ...
1. Cyclic Redundancy Check Cyclic Redundancy Check (CRC) is an error detection method for digital data based on binary division.CRC algorithm generates a fixed checksum code length. 2. How to calculate and generate post-build CRC? Post build CRC ar...
Summary This article provides a step-by-step guide to configure STM32CubeIDE for debugging STM32N6 microcontrollers running TouchGFX applications. It focuses on importing a TouchGFX-generated project into STM32CubeIDE and setting up the necessary de...
1. Question You have an application flashed on the M4 Core of the STM32WB. What happens to this application when you perform a firmware upgrade service (FUS) operation via STM32CubeProgrammer such as a FUS or wireless stack upgrade? 2. Answer There a...
Summary This guide explains how to bring up Ethernet TCP/IP on an STM32H7 board using the lightweight Mongoose networking library, with the NUCLEO-H723ZG used as the reference platform. We walk through creating a STM32CubeMX project, configuring the...
Ultra Librarian is a printed circuit board (PCB) design resource used by electronics engineers to find and download electronic design automation (EDA) symbols, footprints, and 3D models. These resources help developers accelerate the design process....
Introduction STM32CubeIDE 2.0.0 is a major release. In this version, STM32CubeMX is removed from STM32CubeIDE. STM32CubeIDE and STM32CubeMX are now two separate products. This changes the workflow, which we describe and explain in this article. Click...
