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: Prerequisites This project utilizes the following so...
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...
Introduction The DTS (digital temperature sensor) was introduced in the high-performance STM32H7 series (STM32H72x/H73x). This temperature sensor is intended to measure in °C the die temperature called junction temperature (Tj) and not the ambient te...
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 custom board and firmware or with one of ST provided boards and middlew...
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...
No. This is only possible if the communication bitrate does not exceed 1 Mb/s. A CAN2.0A/B transceiver cannot pass through bitrates > 1 Mb/s and transmitting higher bitrates could lead to communication errors due to distortions in bits. Find below...
Yes, it is possible. The transceiver does not have the intelligence to differentiate between CANFD and CAN2.0A/B and filter the CAN frame accordingly. It is just an active component that transforms digital signals to differential signals. The most i...
All STM32 have options and even though the functionalities may vary among the different families and series, they are all meant to allow the user a way to customize the general settings of the microcontroller. Option Bytes are mostly used to pre-conf...
STM32CubeMX is a graphical tool that allows users to configure STM32 MCUs (microcontrollers) and MPUs (microprocessors) quickly and simply. In addition, the tool also assists in generating the corresponding initialization C code for the Arm Cortex-M...
Power consumption in low power mode is higher than expected. Problem remains after reset, but is solved by power cycling the MCU. What is the problem? Issue can be caused by debug in low power mode option. When developers debug their code in low-powe...
Introduction Some of the STM32 microcontrollers have backup registers. These registers can be written/read and protected and have the option of being preserved in VBAT mode when the VDD domain is powered off. In this article we will learn how write, ...
Introduction This article includes preliminary updates of STM32 MCU reference manuals reported since 1st January 2024. It highlights the current description requiring update and the expected one if available. The purpose of this article is to delive...
