Problem Backup SRAM or normal SRAM content is not preserved after reset or wake up from standby. After a reset, the last few bytes written are not kept. Solution This issue appears on STM32 devices that have ECC (Error Code Correction) on internal ...
Introduction The quad-SPI (QUADSPI), Octo-SPI (OCTOSPI), hexadeca-SPI (HSPI), and XSPI interfaces can operate in two different low level protocols: Regular-command and HyperBus. The Regular-command protocol is the classical frame format where the QUA...
Introduction Many users have questions about the relationship between the FDCAN registers: FDCAN_IE, FDCAN_ILS, and FDCAN_ILE in certain STM32 microcontrollers such as the STM32H5 and STM32G4 series etc. This article explains how interrupt grouping ...
Introduction The CAN-FD protocol implements a robust error management mechanism, which is fully implemented in hardware. It is reported mainly by two counters in the same way as CAN2.0 (bxCAN in STM32): Transmit error counter (TEC)Receive error count...
Introduction There are different ways to supply the USB transceivers on STM32H7 products, depending on VDD33USB and VDD50USB availability. 1. VDD33USB pin configuration According to STM32H7 datasheets, when USB is not used, the VDD33USB pin should...
Some applications require periodic sampling of analog signals using an ADC (Analog to Digital Converter) for digital signal processing. The objective of this article is to explain how to configure an STM32 Timer to trigger ADC conversions at a config...
Summary This article presents a step-by-step tutorial on how to develop a USB device with more than a class in the STM32H5 microcontroller using the classical USB library. The tutorial is based on NUCLEO-H503RB and can be easily tailored to any other...
Summary The first stage bootloader (FSBL) is a key component in the boot process of STM32N6 microcontrollers. It is responsible for initializing the system, configuring the hardware, and loading the application code from external memory into the int...
Introduction RCC clocks can be internally connected to timers. The points addressed here are the following: Finding which clock is connected to which timer.Finding how the clock is connected to a timer.Implementing this connection in STM32CubeMX. Thi...
Introduction In this article, we cover the needed steps to use the FreeRTOS™ in tickless mode, specifically entering in STOP2 low-power mode with the STM32U5. In this example, we use the X-CUBE-FREERTOS™ pack with the LPUART and EXTI as the wake up ...
Introduction Many customers requested to have FDCAN communicating at 8 Mb/s. We provide a GitHub hotspot that contains a simple project on several STM32 part numbers. The project allows for FDCAN to reach a bit rate of 8 Mb/s in the data phase. The ...
Introduction ST Open Bootloader is example application code for STM32 microcontrollers providing In-Application programming (IAP) and is offered in the STM32Cube MCU Packages and GitHub. It is fully compatible with the STM32 System Bootloader and sup...
Introduction This article provides a step-by-step guide on how to use the Instrumentation Trace Macrocell (ITM) console to redirect print statements and LWIP debug messages in STM32CubeIDE. These tools are valuable for debugging and optimizing your ...
Introduction In this guide, we explore how to integrate and use the FreeRTOS+ command-line interface (CLI) library to enhance your embedded applications. Designed for ease of use and flexibility, the FreeRTOS+ CLI allows developers to create robust c...
Summary This article includes SPI characteristics and clarification of maximum clock frequency when using PB13 and PB14. They are applicable for STM32H523xx, STM32H533xx, STM32H573, STM32H562xx, and STM32H563xx microcontrollers. The purpose of the a...
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...
