There are two possible solutions for connecting two quad-SPI memories using only one OCTOSPI interface. Solution 1: Use a dedicated bit in the OCTOSPI_CR register for external memory selection: MSEL bit for STM32H5, STM32U5, and STM32L5 series or FS...
Introduction STM32 MCUs users may face an issue with CAN message reception mainly when the CAN2 instance is used. This issue may appear even if the hardware setup is correct, and CAN bit time and filters are configured correctly. If the value of Sta...
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...
While the STLINK-V3 is compliant with USB 2.0 and exhibits reliable USB performance across various platforms since several years, the USB communication may fail between an STLINK-V3 and some recent computers. 1. Root cause The root cause comes from...
After re-programming STM32H7 device, I can’t connect to the device. Connect under reset doesn’t help. Why?There are two possible root causes, that can cause this issue. First one is more probable and is related to power supply misconfiguration. And s...
Summary The STM32 VS Code extension doesn’t natively support OpenOCD, but with some simple configuration, you can integrate it into your debugging workflow. This article covers how to set up OpenOCD (either Streamline or ST’s fork) with the extension...
Introduction On the NUCLEO-WB55RG, we have an embedded ST-LINK/V2-1. However, for several reasons, users may want to use an external ST-LINK for debugging or programming. In this article, I demonstrate a simple use case of programming an STM32WB55RG...
How to use STM32 HAL UART driver API and Callbacks?What are the callbacks involved in UART TX / RX?How are these callbacks called?Why is the callback not called? 1. STM32 HAL UART supports 3 modes for transmitter (TX) / receiver (RX) Polling mode (no...
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...
Summary This article describes tips to prevent or fix errors encountered when connecting the STM32 target board to your computer such as: “No target connected”, “Target not found”, “No ST-LINK detected”, and “ST-LINK connection error”. Software and ...
Introduction In this article, we provide a method to modify TX power levels as available in the STM32CubeWBA using ACI_HAL_SET_TX_POWER_LEVEL and read power levels like HCI_READ_TRANSMIT_POWER_LEVEL. This method is implemented usjng the Zephyr examp...
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...
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 primary objective of this article is to provide a comprehensive step-by-step guide on creating an external flash loader to interface with external memories. This demonstration uses the STM32H7S3L8H6 microcontroller and XSPI to interface ...
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...
Hello and welcome back to the second and last portion! 1. Recap We resume from the point we left off, just to give a brief recap, in part 1 we made all the way up to the code generation with STM32CubeIDE: Among the several files created automatically...
How to configure the MPU of an STM32 using STM32CubeMX1. Introduction The MPU (Memory Protection Unit) is included in the Cortex-M4 and M7 based STM32 Microcontrollers (refer to specific product datasheets to confirm availability). The MPU can be use...
Summary Our STM32Cube_FW_H5 package contains several UDP application examples that can be of great help. This article provides a detailed guide on how to develop an application using NetXDuo and benefit from TrustZone® isolation and security featur...
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 In this article, we explore how to set up and debug a FreeRTOS™ project for the STM32H753 microcontroller using visual studio code (VS Code). We cover the necessary extensions, step-by-step project creation, and debugging processes, inc...
