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...
What is the STM32 boot process and the system bootloader?Summary This article provides information about the STM32 boot process. In a first part, it gives you an overview of this process and it presents the different boot modes. In a second part, it...
Programming a STM32 with another STM32 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 pag...
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-power...
From a USB specification, a USB device should use VBUS sensing detection: When a host connection is detected by the device, the device connects the pull-up resistor either to D+ or to the D- data signal. This allows the host to detect device presenc...
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 datasheets 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 deliver any...
Introduction This article includes preliminary updates of STM32 MCU errata sheets 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 deliver an...
Introduction It is very common that applications require a periodic interrupt that is used as a time-base for triggering tasks, adding delays, keeping track of elapsed time, etc. While this article shows how to configure an STM32 Timer to generate an...
Introduction ST provides several X-CUBE source packages for STM32 on st.com with STM32CubeIDE project files. To open the projects in STM32CubeIDE, there are several ways. Note: some X-CUBE packages are also provided in STM32CubeMX as installable "pac...
Summary This article provides a step-by-step guide on how to use a FDCAN peripheral to establish communication between two NUCLEO-G0B1RE boards. Also, outlining the process from configuring the hardware connections to developing and testing the firm...
