Description

The Panel-Touch Controller is a C-programmable controller with a built-in graphical user interface. It's an ideal "brain" for products that need a smart user interface, computational power, analog and digital I/O and serial communications. Commanded remotely from a PC, or used stand-alone, it provides real-time control of dozens of analog and digital I/O lines. Use it for machine control, embedded systems, scientific instruments, and OEM applications - wherever you need an I/O-rich computer and a smart user interface.

A Ready-Made Graphical User Interface

The Panel-Touch Controller features a touchscreen controlled graphical user interface. Combining a high contrast 128 x 240 pixel display and a 5 x 4 touchscreen, it comes complete with menuing software that makes it easy to control your application using buttons, menus, graphs, and bitmapped pictures.

Display your own user-defined graphics on a bright white-on-blue cold-cathode fluorescent (CCFL) backlit screen. Display screens and graphics objects are quickly developed with most Windows paint programs, such as PC Paintbrush, allowing you to create sophisticated displays including your company logo, system diagrams, and icon-based control panels. Real-time data plotting routines are precoded for you, so the user can see what your instrument is doing. Startup screens and your application program execute automatically on power-up.

You can use hundreds of screens, each with software configurable buttons. A precoded menu manager simplifies menu-driven control, making it easy to define buttons, menus, and their associated actions. With the touch or release of a button, the menu manager software responds, sending an appropriate command to your application program. Onboard software draws the screen graphics and responds to button presses for you, so you can concentrate on your application.

A Powerful Controller and Operating System

The Panel-Touch Controller includes a powerful microcontroller programmed in Control C™ or QED-Forth™. It comes loaded with a real-time multitasking operating system and hundreds of precoded device drivers. Programming is a snap using the interactive debugger and multitasking executive. Libraries of hardware control routines including drawing and plotting functions for the display are preprogrammed for you. Program in ANSI C by compiling your application on your PC and downloading the code to the Panel-Touch Controller where it's automatically executed. The real-time operating system in onboard FLASH memory manages all required initializations and autostarts your application code.

All the I/O You Need

Control dozens of analog and digital I/O lines in real time. The Panel-Touch Controller commands eight 12-bit analog input channels, eight 8-bit analog inputs, eight 8-bit D/A lines, 24 digital I/O lines including timer-controlled and PWM channels, 4 high current drivers, and two RS232/485 ports. Pre-coded I/O drivers are provided for all I/O, and make it easy to do data acquisition, pulse width modulation, motor control, frequency measurement, data analysis, analog control, PID control, and communications.

Plenty of Memory

256K Flash and 128K RAM memory provides plenty of room for your application code and graphic screens. For those really extensive applications that require lots of memory and removable data storage, the Panel-Touch Controller directly mates to the QED Memory Interface Board™, providing an additional 256K Flash and 128K battery-backed RAM and a complete hardware/software interface to Flash or RAM PCMCIA Cards (also called PC Cards) of 64 or 128 Megabytes.

Get a Fast Start with the Panel-Touch Starter Kit

This development package includes everything you need to develop an instrument with a state of the art touchscreen front panel interface, including documentation, battery backed 128K memory, power supply and all cables. For a sleek look you can add a black anodized aluminum bezel. The Panel-Touch Controller can either be flush mounted using the bezel or directly mounted to a panel with a cutout.

Our free technical phone support and comprehensive documentation will help you get the most from this powerful computer.
