1. System (ROM) bootloader The system bootloader is present on all STM32 MCUs. As the name suggests, it is located on the system memory (ROM) area of the MCU. The system bootloader is located on the read only portion of the memory and is programmed ...
The STM32WB as a server can be connected to 8 clients max for the STM32WB3x and STM32WB5x.In contrast, 5 clients max for the STM32WB1x using the stm32wbxx_BLE_Stack_full_fw.bin stack (from STM32CubeWB version 1.21.0). To achieve this, the server nod...
Introduction This article is a step-by-step guide on how to implement an STM32 application as a USB device. This device should combine human interface device (HID) and device firmware upgrade (DFU) functionalities into a composite USB device. This al...
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 ...
Introduction Sharing a MCU board between multiple users may be sometimes challenging when someone makes a modification on the board or in the MCU option bytes and doesn’t notify about it. Additionally, the board owner might forget the changes applie...
Summary This article is a step-by-step guide on how to use the half and interleaved modes of the STM32G4 HRTIM (high-resolution timer). The examples in this article are demonstrated using the B-G474E-DPOW1 board but can be tailored to any other STM32...
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...
Summary The STM32N6 boot ROM is a critical component that initiates the boot process for the STM32N6 microcontroller. It performs various functions such as system initialization, reset source detection, and boot memory device selection. It supports ...
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...
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...
