How to implement custom data processing in STM32CubeMonitor using the function node
Summary This article aims to familiarize readers with STM32CubeMonitor by focusing on understanding its message structure and using the function node to create custom functionalities. The knowledge gained is applied in an example that implements a si...
How to jump to system bootloader from application code on STM32 microcontrollers
Introduction There are many possible ways to access the System Bootloader in STM32 devices and, in this tutorial, we will cover how to easily perform this jump directly from application code for all our families and product series, except for the STM...
How to enable FreeRTOS™ Run Time and Stack Usage view
In this article, we explore the FreeRTOS™ debugging viewers using STM32CubeIDE and how to enable "Min Free Stack" and "Run Time usage" in each task. Introduction To enhance the analysis and validation of the application running on FreeRTOS™, STM32C...
Guide to CAN (bxCAN/CAN2.0) configuration in Loop back mode on STM32 MCUs
Introduction Many STM32 MCUs feature a CAN2.0 interface named bxCAN. The Loop back mode is one of the modes implemented in this peripheral. It is mainly used to test and debug transmit and receive CAN messages and mainly to validate the filter config...
How to enable RDP-like product state flash protection in STM32H5 microcontrollers
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...
FAQ: Troubleshooting a USB core soft reset stuck on an STM32
1. Issue description USB_CoreReset() the USB_OTG_GESTCTL_CSRST bit is never reset and hence a timeout occurs.Here is the call stack: The CSRST bit in the GRSTCTL register is not cleared, resulting in a timeout. do { count++; if (count...
How to configure the linked list mode in STM32CubeMX
Introduction This article provides a step-by-step guide on configuring the GPDMA linked list in STM32CubeMX. It does not cover the legacy standard DMA approach, which is described in the article "How to configure the GPDMA." 1. Software prerequisite...
Getting started with Smart Asset Tracking on ST AIoT Craft
Introduction The "Smart Asset Tracking" project on ST AIoT Craft enables precise monitoring of a physical item's condition. An example could be a package, to determine whether it’s stationary, moving, or experiencing excessive shaking. This rapid cl...
How to create a bare metal HAL Ethernet application on STM32H563/STM32H723
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...
Jump to bootloader from application on STM32H7 devices
In STM32H7, the base address of system memory is different from the entry point of the bootloader. Thus, in order to jump to the bootloader, address "0x1FF09800" should be used instead of "0x1FFF0000". Below, you find a sample code permitting the j...
