Summary This guide details the process of configuring the STM32H573ZIT3Q microcontroller project in STM32CubeMX to assign the TouchGFX middleware to the nonsecure TrustZone® application domain. This is crucial to leverage TrustZone® security feature...
Introduction Some STM32CubeMX users have noticed that the DIRECT_SMPS_SUPPLY option is not displayed when using certain STM32H7 dual-core part numbers, such as STM32H7x5 or STM32H7x7. This article addresses the question: Why is the DIRECT_SMPS_SUPPL...
Summary This article explains how to connect STM32N6 devices using STLINK (JTAG/SWD) and boot ROM (USB/UART) interfaces. It details two methods to program the external flash memory: via STLINK using an external flash loader, and via boot ROM using ST...
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 is applicable for STM32H74x, STM32H75x, STM32H72x, or STM32H73x microcontrollers. We often see developers facing issues with these microcontrollers when they need to use BDMA, or DMA to transfer data to/from the RAM, but no transfer is...
Introduction It can be especially useful during code development to display messages in a terminal window about various system parameters to help with debugging. An easy way to do that is to use the printf function and redirect the output to a UART f...
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...
If your connection is protected by your company's network security protocols, you likely need to configure a proxy or a certificate to be able to access servers and download packages. This is how you succeed in having full server access with our STM...
Introduction Timing aspects are crucial in a CAN bus system design. The designer of the CAN bus system must study it carefully to prevent any communication issues on the CAN network.This article does not cover the CAN protocol description and its fra...
