At ST we offer a lot of Expansion Packages also known as X-CUBE for our STM32.You can download and import these software packages using STM32CubeMX.Let me show you how. 1. Import drivers In STM32CubeMX I have created a project for a STM32G071RBTxLet'...
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...
Summary The first stage bootloader (FSBL) requires a header signature for the boot ROM to load the code from the external memory into the internal RAM. This allows the application’s code to begin execution. Creating this header involves the STM32Sig...
Summary The main objective of this article is to present the STM32H7 spread-spectrum clock generation (SSCG) feature. STM32H7 differs from other series by using PLL fractional with Timer/DMA. For an overall introduction to spread-spectrum clock gen...
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...
Introduction This article presents a quick guidance on how to prevent HardFault occurrences when the ICACHE is enabled on the STM32H5 MCU. 1. Summary and description This article explains why a HardFault may occur when accessing the following: Int...
