Summary This article provides a step-by-step description of a lightweight algorithm to write and retrieve data from flash using virtual addresses. The key aspect is the low footprint and overall simplicity. The code example in this guide is provided...
There are two possible solutions for connecting two quad-SPI memories using only one OCTOSPI interface. Solution 1: Use a dedicated bit in the OCTOSPI_CR register for external memory selection: MSEL bit for STM32H5, STM32U5, and STM32L5 series or FS...
Users experiencing connection issues with the NUCLEO-WB05KZ, NUCLEO-WB07CC, and NUCLEO-WB09KE boards should check if the problem is due to the low-power mode. The low-power mode is activated by the BLE_p2pserver demo, which is pre-programmed on the ...
Introduction This tutorial begins with STM32CubeMX and demonstrates an AI application for the NUCLEO-N657X0-Q board. This example explains how to load an application from external flash memory, execute an AI model inference stored in external flash,...
The low power wakeup radio (LPAWUR) feature is not enabled by default on NUCLEO-WL33CCx boards. It has been designed for the reception of a specific frame to trigger the wake up of a system. To enable and use the LPAWUR feature on the NUCLEO-WL33CCx ...
Hello and welcome back to the second and last portion! 1. Recap We resume from the point we left off, just to give a brief recap, in part 1 we made all the way up to the code generation with STM32CubeIDE: Among the several files created automatically...
Summary This article provides a detailed guide on using VS Code to debug code running from external serial flash on the STM32N6. It covers setting up the development environment, setting up the project with CMake, configuring the debugger within VS ...
Introduction In this guide, we explore how to integrate and use the FreeRTOS+ command-line interface (CLI) library to enhance your embedded applications. Designed for ease of use and flexibility, the FreeRTOS+ CLI allows developers to create robust c...
The NUCLEO-WBA55CG with MB1801-NoUSB-D02 has a different configuration for reset management compared to earlier versions. In the default configuration, the reset via mass storage and the reset via debugging tools are disabled, which may cause issues...
Summary This article provides a comprehensive guide on running AI models from the STM32 model zoo on STM32N6 microcontrollers. It includes step by step instructions on selecting a model, preparing the development environment, and converting the mode...
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...
To add TraceX support to a STM32CubeIDE project and properly use it you’ll need to follow a few steps, described in detail in this article. Goal: Add TraceX support to STM32CubeIDE using X-CUBE-AZRTOS-H7Although the example is using the NUCLEO-H723ZG...
Introduction This article explains how to set up Sigfox connectivity on the STM32WL3x microcontroller. Sigfox is a low-power wide-area network (LPWAN) technology designed for IoT applications requiring long-range and low-energy communication. By fol...
While the STLINK-V3 is compliant with USB 2.0 and exhibits reliable USB performance across various platforms since several years, the USB communication may fail between an STLINK-V3 and some recent computers. 1. Root cause The root cause comes from...
The USB device is detected by the PC (USB host), but the device initialization reports an error, like. "error code 10" on Windows. What is the problem?When using the HAL libraries, the source of this problem can be a too small heap configured in the ...
This article explores the methods of safeguarding your code from unauthorized external access in the STM32H5 series. It delves into the new "Product State" feature, which functions similar to the readout protection (RDP) feature available in other ST...
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...
Introduction As with many microcontrollers, STM32 MCUs could be clocked by an external source like crystals (XTAL) or crystal oscillators (XO). This is in addition to internal clocks such as LSI, HSI, MSI, CSI etc. For crystals, a preliminary calcula...
Introduction The break feature is embedded only in timer peripherals that include complementary outputs. Specifically, it is available in timers that have at least one channel with two complementary outputs. This makes it suitable for: Advanced ti...
