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...
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 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 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 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 ...
Summary This article provides practical steps showing how to inject and check single and double ECC errors in STM32H7 flash memory. Find attached to the article a ECC Flash project for testing purposes. Introduction In the STM32H7 microcontrollers, ...
Introduction VCONN is a dedicated power supply pin in the USB Type-C® connector. It provides power to the cables electronics, such as e-markers (EMC), long cables with data repeaters, and VCONN-powered USB devices. It ensures proper power supply ...
Introduction The STM32H5 microcontroller series has been observed to exhibit issues when using the GO command to start user code after entering the bootloader via a hardware reset. This article aims to explain the problem in detail and provide possi...
Introduction The delay block is an independent peripheral integrated within an STM32 MCU, for example, an STM32U5. Its role is to introduce a phase shift relative to the input clock. The user application configures the phase of the output clock. This...
Introduction The goal of this article is to help readers make sense out of the RTC_SSR register, the RTC’s sub second value (SS), and the second fraction equation. This article uses the STM32L476xx MCU and its reference manual RM0351 as an example, b...
Introduction The USB Type-C® and USB PD specifications revolutionized device connectivity by merging data transfer and power delivery for up to 240 W (with EPR in USB PD 3.1). A key feature, fast role swap (FRS), allows a power supplying device quic...
Introduction Many STM32 users start their development based on one of ST boards either to evaluate the STM32 MCU or to get the proof of concept of their application. One of the first steps to do in the evaluation process is to look at the board schem...
