After reprogramming the STM32H7 device, I can’t connect to the device. Connect under reset doesn’t help. Why? There are two possible root causes for this issue. The first root cause is more probable and is related to power supply misconfiguration. Th...
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...
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...
Introduction This tutorial begins with STM32CubeMX and demonstrates an AI application for the STM32N6-DK board. This example explains how to load an application from external flash memory, execute an AI model inference stored in external flash, and d...
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 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...
Summary This article provides a step-by-step guide on how to configure your STM32H7R/S to transfer ADC converted values in DMA circular mode using STM32CubeMX (version 6.12 is used). For a complete firmware example, refer to the attached project a...
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 In this article, we go through the necessary steps to create a working UDP echo server for the STM32F767 MCU. This demo is applicable to other F7 series microcontrollers with some minor differences in memory addresses depending on the m...
Summary This article allows the process to regress from RDP 2 to RDP 0 on the STM32U5 series. This example uses the STM32U5 Nucleo board with STM32U5A5ZJT6Q and STM32CubeProgrammer V2.13.Note:To regress from RDP2 to RDP0, you must be sure that your ...
Summary This article is intended for users who would like to integrate STM32CubeIDE and GitHub. It covers the entire process from GitHub account creation to integration with STM32CubeIDE. Introduction STM32CubeIDE is an integrated development envir...
Summary and problem description The STM32WL55 is a dual-core, low-power microcontroller with a sub-GHz radio that is connected internally through SPI. Note that whenever "radio" is mentioned in this article, it relates to "sub-GHz radio". To enhanc...
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...
Introduction Since CMSIS V 5.8.0, the CMSIS-DSP libraries are supplied as an individual package. The advantage is to decouple the release cycles of DSP from the CMSIS-Core stuff. As a side-effect, the DSP libraries structure was changed and the step...
Introduction STM32CubeIDE 2.0.0 is a major release. In this version, STM32CubeMX is removed from STM32CubeIDE. STM32CubeIDE and STM32CubeMX are now two separate products. This changes the workflow, which we describe and explain in this article. Click...
Summary This article continues the practical guide on integrating and debugging external memory with STM32 MCUs, focusing on firmware configuration, initialization, and comprehensive validation techniques. It highlights key firmware settings, middle...
Summary This article addresses the critical process of integrating and debugging external memory on STM32 microcontrollers, emphasizing a systematic approach that integrates hardware verification, firmware configuration, and validation. It highlight...
What is the ST product longevity commitment program? The ST product longevity program is a formal commitment by STMicroelectronics to ensure the long-term availability of ST products for a defined period of 7, 10, 15 or 20 years. STM32 product longev...
Summary In the STM32H7 dual core series (STM32H745/755 and STM32H747/757), some resources are shared and must be initialized only once. This is notably the case for the clock tree. For this purpose, one core waits while the other performs the necessa...
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...
