Embedded Wizard is Harnessing the Power of Open-CMSIS-Packs

In the rapidly evolving landscape of embedded systems, efficiency and accessibility are crucial factors that drive innovation and product success. The traditional approach often involves writing individual code tailored to a specific platform. However, in today’s dynamic environment, the need for reusability and a rapid software development process has become increasingly apparent.

As engineers strive to develop innovative solutions, they often grapple with the complexities of integrating new functionalities such as graphical user interfaces (GUIs) into microcontroller-based systems. With standardized solutions like the Common Microcontroller Software Interface Standard (CMSIS), interoperability of software components from multiple vendors is enabled and developers gain access to a streamlined workflow that enhances productivity and accelerates innovation. The availability of the GUI solution Embedded Wizard as Open-CMSIS-Packs for a wide range of NXP platforms stands as a prime example of leveraging software reusability and simplifying development processes.

Understanding Open-CMSIS

Open-CMSIS-Packs are comprehensive software packages provided by software companies and hardware manufacturers. These packs include software interfaces for microcontroller peripherals, real-time operating systems as well as middleware components, a delivery mechanism for standardized software components, and in many cases even come with usage examples.

An Open-CMSIS-Pack can contain source code, header files, startup code, software libraries, documentation, and example projects specifically tailored for Arm-based microcontrollers. By offering standardized software components, it simplifies the development process for these systems, thereby facilitating seamless software development.

Arm, the driving force behind the Cortex core designs, recognized the need for cohesive communication among microcontroller manufacturers and third-party software providers. As a result, the Open-CMSIS-Pack concept was born, aiming to standardize the distribution of software components across different platforms and vendors. Designed to assist embedded developers working with Arm Cortex-based devices, the Open-CMSIS-Packs streamline the reusability of software, expedite project builds, debug processes, and minimize time-to-market for new products. With more than 1,100 different Open-CMSIS-Packs offered by over 80 pack vendors and the support for 500 development boards, the Open-CMSIS project caters to a wide range of embedded system development needs.

The Open-CMSIS-Pack initiative aims to establish a robust infrastructure facilitating the integration and management of software components, thereby enhancing code reusability across embedded projects. Spearheaded by Linaro in collaboration with Arm, NXP, and ST, the project is presently incubated and overseen by these key industry players. In the realm of microcontrollers, ensuring software compatibility and component reusability has posed persistent challenges. The Open-CMSIS-Pack initiative seeks to address this issue by simplifying complexities associated with software component packaging. It establishes a standardized framework encompassing essential tools for validation, distribution, integration, management, and maintenance of software components, thereby fostering a more streamlined development process.

The Role of Embedded Wizard

TARA Systems embraces this standardization effort by offering Embedded Wizard, an award-winning solution for GUI development, in the form of easy-to-use Open-CMSIS-Packs. Software developers can leverage TARA Systems’ experience in GUI development by relying on the recently completed Open-CMSIS-Packs for NXP development boards. By offering tailored packs for various NXP development boards, it is ensured that the user experience remains consistent across all platforms, regardless of the underlying microcontroller or used integrated development environment (IDE). With each pack containing project examples for different IDEs, such as Keil µVision and IAR Embedded Workbench for Arm, developers can seamlessly start to use Embedded Wizard in their development workflow.

As quoted by Manuel Melic, Product Manager for Embedded Wizard, “Our extensive experience enables us to provide a high-quality solution tailored to the specific requirements of NXP microcontrollers. Our expertise ensures a reliable software solution that offers regular updates and comprehensive support to assist our customers throughout the entire product lifecycle.”

Benefits of Using Open-CMSIS-Packs

But what does this mean for our customers and the end-users? The benefits are manifold. Open-CMSIS-Packs represent a significant leap forward in software abstraction, offering a repository of pre-built software components for various microcontroller architectures and IDEs. With standardized software components readily available at their fingertips, developers can expedite project timelines, reduce development costs, and enhance overall productivity.

Faster Development

By leveraging Open-CMSIS-Packs, Embedded Wizard users gain access to a treasure trove of functionalities, including optimized device drivers, various IDE project configurations and detailed GUI examples right at their disposal. This means that developers can focus their efforts on crafting intuitive user interfaces, instead of reinventing the wheel for common software functionalities.

In addition, Open-CMSIS-Packs provide an efficient way for developers working with Cortex-based CPUs. The standardized software delivery interface ensures consistency in the user experience across different development boards. For example, downloading “Hello World” for a NXP hardware with display support results in an identical GUI, independently from the display resolution or available hardware accelerator. This enhances the developers’ learning curve and allows them to quickly understand how to start and create a modern GUI, resulting in a productivity boost.

Consider the scenario of an engineer tasked with adding a touchscreen display to a coffee machine. In this case the engineer most likely uses his favorite IDE, for example Keil µVision, and will start to search for examples containing a GUI. With Embedded Wizard’s presence within the IDE, finding a suitable example becomes a straightforward process. The engineer can quickly access project examples tailored for the use of a GUI powered by Embedded Wizard, and start working on the project.


Another advantage of using Embedded Wizard as Open-CMSIS-Pack is the unparalleled level of flexibility it affords developers. Since Open-CMSIS-Packs adhere to a standardized interface for configuring microcontroller peripherals, the packs can act as reference for integrating a GUI into a custom developed hardware. Whether engineers are working with different microcontrollers or prefer other IDEs, Embedded Wizard Open-CMSIS-Packs ensure seamless interoperability, code reusability and portability.

Simplified Accessibility

Moreover, the integration of Embedded Wizard as Open-CMSIS-Pack simplifies the search for GUI software examples and read-to-use IDE projects. By providing a centralized repository, developers can easily find what they need without wading through irrelevant search results. Instead, they can easily locate GUI examples tailored to their specific microcontroller platform. In a landscape cluttered with disparate offerings, Embedded Wizard stands out as a beacon of quality and convenience.
