Developed in partnership with the world’s leading chip companies over a 12 year period, FreeRTOS is the market leading real time operating system (or RTOS), and the de-facto standard solution for microcontrollers and small microprocessors.

SAFERTOS is a safety certified Real Time Operating System (RTOS) for embedded processors. It delivers superior performance and pre-certified dependability, whilst utilizing minimal resources.

TouchGFX is a unique software framework that unlocks the graphical user interface (GUI) performance of your low-resource hardware. The revolutionizing technology breaks existing restraints, as it lets you create sophisticated GUIs that fully live up to today’s smartphone standards at a fraction of the cost.

emWin is designed to provide an efficient, processor- and LCD controller-independent graphical user interface (GUI) for any application that operates with a graphical LCD. It is compatible with single-task and multitask environments, with a proprietary operating system or with any commercial RTOS. emWin is shipped as “C” source code. It may be adapted to any size physical and virtual display with any LCD controller and CPU.

Micrium is a global RTOS leader and a top choice of embedded engineers building microprocessor, microcontroller, and DSP-based devices. Micrium’s commercial RTOS components such as the μC/OS product family are the preferred solution at thousands of companies around the globe. Offering unprecedented ease-of-use, μC/OS-III is delivered with complete 100% ANSI C source code and in-depth documentation. μC/OS-III runs on the largest number of processor architectures, with ports available for download from the Micrium Web site. µC/OS-III allows for unlimited tasks, semaphores, mutexes, event flags, message queues, timers and memory partitions. µC/OS-III provides features to allow stack growth of tasks to be monitored. µC/OS-III also supports an unlimited number of priority levels. µC/OS-III’s footprint can also be scaled to contain only the features required for a specific application.

Crank Software
Crank™ Software Inc. is an innovator in embedded user interface (UI) solutions. Compared to traditional electronic design automation tools, Crank’s products and services enable R&D teams to more quickly develop rich graphical displays—also called UIs or HMIs—for resource-constrained embedded devices. Applications include in-car graphical displays, animated GPS systems, and rich user interfaces on factory floors. Crank Software bridges the gap between UI design and embedded systems to deliver competitive advantage because streamlining the development lifecycle enables their customers to get products to market faster, with higher ROI and lower TCO, while delivering a superior customer experience. Crank Storyboard™ Designer enables user interface (UI) designers to easily prototype the look and feel of a product, and then deploy a production-ready interface directly to the embedded target. Designers maintain full control over the UI and user experience (UX) without having to perform a hand off to an embedded systems engineer for implementation.
