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...
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...

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 ...

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 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...
Problem formulation Examples provided by ST may not fit your specific STM32WL or other STM32 family chips in a given package. As a result, you may be in a situation where you cannot use the full potential of the STM32CubeMX software with your chip. ...
Summary Step-by-step tutorial on how to implement the AzureRTOS's USBX package for CDC host class based on the NUCLEO-H723ZG board. Introduction This article shows how to implement the USB host CDC in the STM32 using the Azure USBX package. USBX is ...
Introduction The STEVAL-IDB012V1 includes a CMSIS-DAP debugger and programmer. It has support for USB to UART I/O communication, virtual COM port, and drag and drop programming functionality. For quick and easy application prototyping and debugging,...
Introduction The STEVAL-IDB011V1/V2 includes a CMSIS-DAP debugger and programmer with support for USB to UART I/O communication. It also includes a virtual COM port, and drag and drop programming functionality. For quick and easy application prototy...
