Introduction Many STM32 MCUs feature a CAN2.0 interface named bxCAN. The Loop back mode is one of the modes implemented in this peripheral. It is mainly used to test and debug transmit and receive CAN messages and mainly to validate the filter config...
Introduction For various reasons, developers may need to deactivate booting of a core in the STM32H7 dual core product. This article shows how to disable the Cortex®-M7 and Cortex®-M4 cores and enable them again. 1. Disabling a core in a dual-core co...
Summary This article provides a step-by-step guide on how to calibrate the precision of a real-time clock (RTC). The examples in this guide are provided using the NUCLEO-U575ZI-Q board, but can be tailored to any other STM32. Introduction The real-t...
Summary The first stage bootloader (FSBL) is a key component in the boot process of STM32N6 microcontrollers. It is responsible for initializing the system, configuring the hardware, and loading the application code from external memory into the int...
Summary This article provides a quick guide on what the STM32N6’s OTP bits are and how to program them. It includes step-by-step instructions and explanation on configuring the OTP124, responsible for changing the VDDIOs' voltage to 1.8 V instead of...
Defining HSLV HSLV is a characteristic of certain I/O ports that allows them to operate at higher speeds while using lower voltage levels. This feature is particularly useful for applications that require fast data transfer rates without the higher ...

Summary This article provides a step-by-step method to test the ECC single and double errors in the STM32H7 series. Find attached to the article a ECC RAM project for testing purposes. Introduction In STM32H7 microcontrollers, RAM ECC (Error Correc...
Summary This article is an introduction to STM32 MCU development through the VS Code IDE. In this article, we cover the following: Setting up your VS Code environment to interface with STM32 MCUsCreating a new project through the embedded CubeMX plat...
At ST we offer a lot of Expansion Packages also known as X-CUBE for our STM32.You can download and import these software packages using STM32CubeMX.Let me show you how. 1. Import drivers In STM32CubeMX I have created a project for a STM32G071RBTxLet'...
This article demonstrates how to implement a webserver application using the AzureRTOS ecosystem, relying on the NetXDuo stack for Ethernet communication. We also use FileX for hosting the pages in the MCU’s embedded flash and ThreadX as RTOS. The d...
Summary The first stage bootloader (FSBL) requires a header signature for the boot ROM to load the code from the external memory into the internal RAM. This allows the application’s code to begin execution. Creating this header involves the STM32Sig...
Summary This article provides a step-by-step guide on how to use the LwIP with the STM32H5 series. A simple DHCP connection is made using the NUCLEO-H563ZI board, outlining the process from configuring the basic hardware connections up to the firmwar...
Summary The main objective of this article is to present the STM32H7 spread-spectrum clock generation (SSCG) feature. STM32H7 differs from other series by using PLL fractional with Timer/DMA. For an overall introduction to spread-spectrum clock gen...
1. GPDMA module setup The new DMA module (which includes the GPDMA and the LPDMA) available in series such as the STM32U5 are slightly different than the regular DMA. In this article, we’ll discuss the setup for using GPDMA in a similar way as the st...
Introduction This article presents a quick guidance on how to prevent HardFault occurrences when the ICACHE is enabled on the STM32H5 MCU. 1. Summary and description This article explains why a HardFault may occur when accessing the following: Int...
Summary This article guides you on how to use FileX, a fully compliant FAT library for media storage and file system management with eMMC. In this example, the selected hardware is an STM32U5A9-DK board featuring anintegrated eMMC card readily avail...
1. System (ROM) bootloader The system bootloader is present on all STM32 MCUs. As the name suggests, it is located on the system memory (ROM) area of the MCU. The system bootloader is located on the read only portion of the memory and is programmed ...
The STM32WB as a server can be connected to 8 clients max for the STM32WB3x and STM32WB5x.In contrast, 5 clients max for the STM32WB1x using the stm32wbxx_BLE_Stack_full_fw.bin stack (from STM32CubeWB version 1.21.0). To achieve this, the server nod...
Introduction This article is a step-by-step guide on how to implement an STM32 application as a USB device. This device should combine human interface device (HID) and device firmware upgrade (DFU) functionalities into a composite USB device. This al...
