Azure RTOS GUIX

Azure RTOS GUIX is a professional-quality package, created to meet the needs of embedded systems developers. Unlike alternative GUI solutions Azure RTOS GUIX is small, fast, and easily ported to virtually any hardware configuration that’s capable of supporting graphical output. Azure RTOS GUIX also delivers exceptional visual appeal and an intuitive and powerful API for application-level user interface development.

Azure RTOS GUIX Studio provides a complete, embedded graphical user interface (GUI) application design environment, facilitating the creation and maintenance of all graphical elements in the application’s GUI. Azure RTOS GUIX Studio automatically generates C code that’s compatible with the Azure RTOS GUIX library, ready to be compiled and run on the target.

The Azure RTOS GUIX Studio installer is available here: https://aka.ms/azrtos-guix-installer.

Here are the key features and modules of GUIX:

GUIX Key Features

Getting Started

Azure RTOS GUIX as part of Azure RTOS has been integrated to the semiconductor's SDKs and development environment. You can develop using the tools of choice from NXP, Renesas and Microchip.

We also samples using hero development boards from semiconductors you can build and test with.

See Overview of Azure RTOS GUIX for the high-level overview, and all documentation and APIs can be found in: Azure RTOS GUIX documentation.

Branches & Releases

The master branch has the most recent code with all new features and bug fixes. It does not represent the latest General Availability (GA) release of the library. Each official release (preview or GA) will be tagged to mark the commit and push it into the Github releases tab, e.g. v6.2-rel.

When you see xx-xx-xxxx, 6.x or x.x in function header, this means the file is not officially released yet. They will be updated in the next release. See example below.

Component dependencies

The main components of Azure RTOS are each provided in their own repository, but there are dependencies between them, as shown in the following graph. This is important to understand when setting up your builds.

dependency graph

You will have to take the dependency graph above into account when building anything other than ThreadX itself.

Building and using the library

Instruction for building the GUIX as static library using Arm GNU Toolchain and CMake. If you are using toolchain and IDE from semiconductor, you might follow its own instructions to use Azure RTOS components as explained in the Getting Started section.

  1. Install the following tools:

  2. Build the ThreadX library as the dependency.

  3. Cloning the repo.

    $ git clone https://github.com/azure-rtos/guix.git
  4. Define the features and addons you need in gx_user.h and build together with the component source code. You can refer to gx_user_sample.h as an example.

  5. Building as a static library

    Each component of Azure RTOS comes with a composable CMake-based build system that supports many different MCUs and host systems. Integrating any of these components into your device app code is as simple as adding a git submodule and then including it in your build using the CMake add_subdirectory().

    While the typical usage pattern is to include GUIX into your device code source tree to be built & linked with your code, you can compile this project as a standalone static library to confirm your build is set up correctly.

    An example of building the library for Cortex-M4:

    $ cmake -Bbuild -GNinja -DCMAKE_TOOLCHAIN_FILE=cmake/cortex_m4.cmake .
    
    $ cmake --build ./build

You can also check previous questions or ask new ones on StackOverflow using the azure-rtos and guix tags.

Security

Azure RTOS provides OEMs with components to secure communication and to create code and data isolation using underlying MCU/MPU hardware protection mechanisms. It is ultimately the responsibility of the device builder to ensure the device fully meets the evolving security requirements associated with its specific use case.
