Embedded Controller
The QVGA Controller is a C-programmable embedded computer with a touchscreen controlled graphical user interface on a 1/4 VGA display. The controller comes with a high contrast 320×240 pixel electroluminescent (EL) or LCD graphics display, a high-resolution analog touchscreen, and a built-in GUI software toolkit. The toolkit designs and implements a complete graphical interface to monitor and control an instrument. It can design a user interface containing controls that, when pressed, execute programmer-defined functions, and the software can also be used to display system status using graphical representations (such as bar graphs) or via text-based messages.
