Human Machine Interfaces more popularly referred as HMI Systems are the faces of modern machinery. Also called as Man Machine Interface, HMIs are nowadays the primary mechanism with which the operators interact with the machines which in turn calls for a capable mechanism for visual communication. Sparklet LCD graphics library and Flint hmi interface design tool are the answers for need for such a HMI Graphics library.
For any kind of industrial applications - manufacturing, process control, environment monitoring, fleet management etc the Man Machine Interfaces/HMI's provide a one-point interface through which the operators/users communicate with the overall system. Based on the exact application, the HMI could be very complex. It may be supporting functionality equivalent to hundreds of selectors, push buttons, LEDs etc. Alarms and warnings have to be notified visually and effectively. Multiple connectivity options might also be supported and more than one machinery might be managed by a single operator interfaces. Such a device needs innovative design with enhanced look and feel that calls for a specialized HMI Graphics library.
Sparklet GUI library helps develop next generation HMIs with reduced foot prints and development time. The path-breaking design lowers processing requirements there by leading to more processing power used for core functionality. Faster response time can be achieved easily. Advanced simulation tools and development framework lead to faster development of such a system. Dynamic configuration is possible to quickly reconfigure on-screen display as per need/emergency conditions.
Sparklet aids in responsive design of the display customized to the aesthetics of the physical design. Clarity offered by the widgets leads to efficient and uniform design. Other features like zooming/scaling and orientation changes are also possible with Sparklet.
All these can be achieved even without using an Operating System or a simple basic RTOS. Such is the power of the LCD graphics library! For many basic HMI systems, there are few interfaces like RS485, Ethernet and limited storage/functionalities that may not need full-fledged OS like Linux, rather a simple scheduling routine or at max a RTOS. Many open source HMI software libraries need Linux/other OS for seamless operation. But with Sparklet Embedded GUI library, it is perfectly possible to achieve premium graphics performance.
If the HMI functionality is larger and in need of OS like Linux, Sparklet could again the preferred Linux HMI graphics Library.
