How to find the RAM ECC failing address? How to access to the right RAMECC monitor to get the RAM failing address when an ECC error occurs?How to translate the content of the failing address register to the actual RAM address (e.g. FADD= 0x2004)? No...
Ethernet reference clock affecting ADC values in STM32 microcontrollers In various STM32 microcontroller applications, the Ethernet reference clock (ETH_REF_CLK) has been observed to introduce noise into ADC (analog-to-digital converter) measurements...
Summary In this article, we guide the users of the Azure NetX Duo middleware to handle multiple TCP clients on the STM32H563 microcontroller as an example. This guide is divided into two parts: Handling multiple clients on the same portHandling mult...
1. Introduction Optimizing power consumption is one of the biggest challenges when designing an MCU based application.In this article we selected the STM32F401 MCU that can be configured in four different modes: Run mode, Sleep mode, Stop mode and St...
Introduction For those developing applications that use low power modes, trying to achieve the current consumption numbers listed in the datasheet and performing general debugging can be troublesome. The purpose of this article is to give an overall...
Maximum FIFO size with the OCTOSPI interface The FIFO is sized into the targeted product, typically either 32 or 64 bytes depending on the product. Refer to the reference manual to check the maximum size in the "FIFO and data management" section. Co...
The STM32H7 MCU family clock reaches up to 600MHz and thermal management matters due to power dissipation, see details in the AN5036 Guidelines for thermal management on STM32 applications. https://www.st.com/resource/en/application_note/an5036-guid...
How to create a Thread using AzureRTOS and STM32CubeIDE? Using the software package available in the STM32Cube ecosystem is straight forward, all steps and a demo code are provided in this article. Goal: The purpose of this article is to give you ...
Introduction STM32 MCUs users may face an issue with CAN message reception mainly when the CAN2 instance is used. This issue may appear even if the hardware setup is correct, and CAN bit time and filters are configured correctly. If the value of Sta...
Summary To understand how middleware like NetXDuo and LwIP use the STM32 HAL Ethernet driver, this article demonstrates a bare metal application to send and receive Ethernet frames. If you are not interested in following the step-by-step tutorial you...
Introduction Debug authentication is a critical security feature of the system considering that with a debugger the user can access a large part of the system. To control a reopening of the debug port, the device imposes a debug authentication proto...
How to configure and use the DTS (Digital Temperature Sensor) on the STM32H71. Introduction The DTS (Digital Temperature Sensor) was introduced in our high performance STM32H7 family. In this article we will see how to configure and use this peripher...
Introduction In this article, we discuss some debugging tips when the Ethernet is not working as expected. When working with the Ethernet peripheral on an STM32 either through a costume board and firmware or with one of ST provided boards and middle...
Summary This article offers a quick guide on how to implement anomaly detection using NanoEdge. It provides a step-by-step tutorial accessible to AI novices on how to use the tool. The demo implemented is based on a simple orientation detection appl...
Summary This article presents a comprehensive guide on utilizing NanoEdge AI Studio to develop a data logger for embedded projects on Arm® Cortex® -M MCUs. It addresses the essential prerequisites, initiates a project with data logger generation, an...
Introduction The debugger is a tool that permit the programmer to monitor and track its code. It is very useful to execute the code step by step and see how it responds, it also helps to indicate the source of an error in case of malfunction.The debu...
Introduction CAN bus is a robust protocol to transmit/receive data. It can be very sensitive to any issue that could lead to communication errors or even halt communication. STM32 users need to have a basic knowledge of the CAN bus (protocol + hardwa...
