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...
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 with the Zephyr exampl...
1. 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 used to make an embedded system more robust and more secu...
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 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...
Summary This article highlights some tips on using VS Code with STM32. In this article, we cover the following: Performing a clean build of your project and deleting the cacheAdding source files, directories, and include files to your VS Code project...
This article covers how to create a custom build setup to allow users to customize, modify, and add specific build settings for each file, folder, or project. Introduction Creating a custom build in STM32CubeIDE can be a powerful tool for developers...
This article will show you how wake up the STM32U5 MCU from Stop 2 Low Power mode using the LPUART1 supplied by LSE or HSI Clock Source. By the end of this article, you will know the needed steps to properly set the LPUART, RCC and PWR peripheral reg...
Summary X-CUBE-EEPROM is an EEPROM emulation software package that works on a variety of STM32 MCUs. Upon downloading the package, there are premade examples that work with STMicroelectronics development kits. However, it is not obvious how you can...
Summary This article provides a step-by-step guide on how to create a memory section in the linker script. Additionally, how to allocate a variable in that specific memory address region using two different IDEs: STM32CubeIDE and IAR EWARM. Introdu...
Introduction There is an embedded terminal available in the STM32CubeIDE that can be used to send and receive data. This is a very easy to use feature that can be used with most of our evaluation boards that open a VCOM, such as the NUCLEO boards. In...
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 It is very common for HMI-of-Things applications to have the capability to control and display data between a user and the machine. Such applications require the ability to interface with external memory such as SDRAM that is used as fra...
Summary This article shows how to implement inter-processor communication between CM7 and CM4 cores on the STM32H7 series through hardware resources. This article uses the bare metal OpenAMP method.If you're looking for inter-processor communication...
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 The NRST pin can be configured in GPIO mode and this is handy for small packages such as STM32C011 8-pin package. In this article, we explain the constraints and potential workaround of using NRST pin in GPIO mode. STM32C011D6Yx 8pin pa...
Introduction As many know, CAN test mode is used for debug or test. One of the test modes is the CAN Loop back mode which is mainly used when only one CAN node is available, and the user needs to test the CAN functionality with no need to establish ...
