Summary This article explains how to add post build commands in VS Code with CMake for STM32 projects. Introduction When developing STM32 firmware using Visual Studio Code with the CMake extension, the build process often involves more than simply c...
Summary This article explains how to debug an external *.elf file in Visual Studio Code (VS Code) using the STM32CubeExtension, without requiring a CMake project or a full development environment. Introduction Debugging embedded applications on STM3...
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...
Summary The following article is a tutorial on how to implement the USB device, HID mouse class, using the Azure RTOS USBX package in standalone mode (without the RTOS). 1. Introduction Hello developer and welcome to this article! For this tutorial,...
Introduction This article provides a step-by-step guide to implementing a composite USB device that combines mass storage class (MSC) and human interface device (HID) functionalities on an STM32 platform. Such a device is ideal for applications requi...
Summary This article presents a tutorial for importing and using the legacy STMicroelectronics USB middleware in the new lines of STM32 to implement a CDC class to open a virtual COM port. The STM32H5 series was selected for this tutorial, but the st...
Summary This article provides a quick guide on how to enable and add real-time clock (RTC) on STM32N6 MCUs and configure it accordingly. This tutorial uses the STM32N6570-DK for the demonstration. Introduction The real-time clock (RTC) is an indepen...
Summary There exist a few helpful examples of UDP applications in our X-CUBE-AZRTOS-H7 package. However, you may find that these examples are not helpful in understanding the steps needed to bring up a similar application on your custom hardware. Th...
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...
1. GPDMA module setup The new DMA module (which includes the GPDMA and the LPDMA) available in series such as the STM32U5 are slightly different than the regular DMA. In this article, we’ll discuss the setup for using GPDMA in a similar way as the st...
