Introduction A library is a collection of reusable, compiled, and tested code that can facilitate the coding of application functionalities. It is designed to support both the code developer and code compiler during the build process and the running...
Introduction Some external USB HS PHYs compatible through the ULPI interface are detailed in Table 12, compatible USB HS PHY in AN4879. However, not all transceivers could be listed in the application note. Compatibility checking is necessary before...
In our example here, we will use the Nucleo-H742ZI as our STM32 board to show you how to use the STM32CubeProgrammer to access the target’s USB-DFU bootloader.Every STM32 MCU comes pre-programmed from our factory with a system memory bootloader store...
In this example, we will use the Nucleo-H743ZI as our STM32 reference board to show you how to leverage the STM32CubeProgrammer GUI to access the target’s USART bootloader.Every STM32 MCU comes pre-programmed with a system memory bootloader stored in...
Introduction In the field of embedded systems, it is very common to migrate an existing design from one STM32 microcontroller to another in response to changing application requirements. These changes can be dependent on, for example, flash memory, S...
Software updates can be tricky. They often bring new features and fixes, but they can also introduce complications, particularly with migrating projects. Some users like automatic updates, but other users want to remain on a specific version that the...
SMPS (Switched-Mode Power Supply) Theory In packages with an integrated SMPS, the STM32 embeds two regulators that can be selected when the application runs, depending on the application requirements: one LDO (Linear Voltage Regulator) and one SMPS s...
Introduction It is very common for HMI-of-Things applications to have the capability to control and display data between a user and the machine. Such applications require the ability to interface with external memory such as non-volatile memories tha...
This is part 2 of an article, if you would like to read part 1 click here. Coding your application using STM32CubeIDE: 3.1 Generate your source files and edit Note: the full completed project with the source code is attached in the link section [3]....
Introduction The main objective of this article is to provide a step-by-step guide on how to improve DCMI frame rate. This demo uses a STM32U575I-EV that is mounted to a ov5640 camera module, but it can be easily tailored for other microcontrollers...
Within the Cube firmware packages, there are examples of in-application USB DFU that were originally created for use with the DFuse software utility. DFuse is now not recommended for new designs, so the purpose of this article is to show how these ex...
Introduction In some applications, specifically battery-powered ones, it is common for the supply voltage to drop as the battery discharges. Sometimes, both VDDA and VREF+ is powered directly by the battery. The problem with this is if the VDDA is b...
Introduction This article discusses the theory behind making a bit-bang driver as efficient as possible. In the bottom of this article, I have attached a single header file based bit-bang SPI controller mode 0 driver. 1. Pros and cons of a bit-bang ...
1. Introduction STMicroelectronics offers BSPs (Board Support Packages) for all STM32 Evaluation and Nucleo boards as well as Discovery Kits. In this article we will see how to add a BSP to your STM32CubeIDE project. 2. Prerequisites Hardware: Min...
This article is a continuation of Part 1: Introduction to the STM32 microcontroller clock system.We recommend reading part 1 of the article before reading this article. 1. Clock security system (CSS) 1.1 Clock security system on HSE If a failure is ...
Introduction In this article, you are introduced to the basics of the STM32 clock system. Furthermore, the tools that are used to easily configure the STM32 clock system. We split the article into two parts. Part two will discuss additional features...
Introduction The main objective of this article is to provide a step-by-step guide on how to develop and add your own external loader to manage external memories. This demo implementation uses a STM32U5A9J-DK and octo-SPI interface, but it can be ea...
Common causes for issues during the install and activation process, are network communication problems. 1. Checklist, in order of importance Antivirus silently blocking network connectionsProxy with incorrect settings (try with no proxy first)VPN bl...
Summary This article presents a quick guidance on how to clone an existing dual core project for any STM32 dual core MCU. Introduction In this article, a few steps are presented as guidance to copy/clone an existing dual core project for the STM32H7...
The usual free offer for a LoRaWAN server usually consists of only one network with up to 10 devices per registration. So the purpose of this tutorial is to show, that the Network server of the LoRaWAN network can be quite simple and running on a loc...
