Mosaic Industries has released a graphical user interface (GUI) software tool kit for its QVGA controller, a touchscreen-controlled embedded computer.
The new GUI toolkit provides an easy way to design and implement a complete graphical interface on the QVGA controller to monitor and control instruments or industrial processes.
"With our new easy-to-use toolkit you can create sophisticated system diagrams and screens that combine buttons, graphics, and text boxes to control your instrument", said David Siu, Mosaic's lead Design Engineer.
"With the GUI toolkit, programmers will be able to build an operator interface using a simple, intuitive syntax".
Display screens and graphics objects are quickly developed using any Windows paint program, such as PC Paintbrush.
The GUI toolkit's object-oriented menu software makes it easy to design an instrument's front panel containing controls that, when pressed, execute programmer-defined functions.
Controls may modify items displayed on the screen, acquire data from the user, or implement hardware actions.
The GUI toolkit can also display system status using graphical representations, such as bar graphs, or text-based messages.
The GUI toolkit is packaged as an operating system extension with a published glossary of programmer accessible functions, and runs on the QVGA controller's 68HC11 processor.
The QVGA controller mates a full-featured embedded computer to a high-contrast 320 x 240 pixel electroluminescent (EL) or LCD graphics display and a high-resolution four-wire analogue touchscreen.
The QVGA controller contains plenty of I/O: it commands eight 12bit analogue input channels, eight 8bit analogue inputs, eight 8bit D/A lines, 26 digital I/Os, four high-current drivers, and two RS232/485 ports.
For projects requiring a unique combination of specialized I/O, the QVGA controller hosts up to eight stackable I/O modules to add dozens more digital and high-resolution analogue signals, isolated I/O, additional high-speed buffered serial lines, and Compact Flash mass memory.
The GUI toolkit is sold as part of the QVGA controller.
The complete product including the hardware and software is available now; the price starts at $799 with substantial volume discounts.
