Introduction This article provides a step-by-step guide on configuring the GPDMA linked list in STM32CubeMX. It does not cover the legacy standard DMA approach, which is described in the article "How to configure the GPDMA." 1. Software prerequisite...
Summary The first stage bootloader (FSBL) is a key component in the boot process of STM32N6 microcontrollers. It’s responsible for initializing the system, configuring the hardware, and loading the application code from external memory into the inte...
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 This guide explains the steps to connect STM32WB, STM32WBA, or STM32WB0 series devices to the STM32CubeMonitor-RF tool. STM32CubeMonitor-RF is a software utility designed to monitor and analyze wireless communication, particularly...
Summary This article summarizes a method to remove the external 32.768 LSE crystal and replace its functionality with a clock reference sourcing from the 32MHz HSE. It also describes the necessary configuration modifications to implement a Bluetooth...
Summary This article presents a tutorial on how to implement the USB Device CDC in the STM32 using the Azure USBX package. Azure USBX is an RTOS USB embedded stack developed by Microsoft® that offers a wide range of classes to be implemented both fo...
Summary In this article, we implement the host side using one STM32 to program another STM32 via the USART interface by leveraging the native system bootloader. The entire project is available at our GitHub page. However, all the steps needed are ex...
Introduction This article provides a detailed, step-by-step guide to implementing a USB mass storage class (MSC) device using the USBX middleware in standalone mode (without an RTOS) on the STM32U5 microcontroller. The example is developed and tested...
Summary This tutorial is a comprehensive guide for debugging code from external serial flash on the STM32N6. It covers: setting up the environment, configuring the debugger, and validating the setup. Introduction To debug the code running from the e...
The voltage reference buffer embedded in most STM32 devices serve two main purposes: 1. used as a voltage reference for ADCs, and DACs 2. used as a voltage reference for external components through the VREF+ pin Note that as each product family is un...
Introduction Some STM32 MCUs embed two unique identifiers: a unique 96-bit unique identifier and device ID. This article shows how to both obtain these values in your code, and describe some possible use cases for them. 1. 96-bit unique ID This 96-b...
Introduction Following the knowledge article on configuring USB FIFO over USB OTG, this article focuses on practical FIFO memory allocation and configuration examples for different USB device applications on an STM32. 1. Memory allocation parameters...
Introduction This article provides an in-depth explanation of the FIFO (First-In First-Out) architecture implemented in USB OTG controllers operating in device mode on STM32 microcontrollers. The USB system features up to 4 Kbytes of dedicated RAM w...
Introduction The readout protection (RDP) is a security feature that protects flash memory from any unauthorized access. This protection notably prevents an external debugger from reading or modifying the memory content, which is crucial for safegu...
Introduction to CK_INT clock The STM32 products include a flexible clock system for timers, enabling each timer to operate with a specific kernel clock. The RCC configuration determines the kernel clock source for each timer.Timers can utilize vari...
