I/O-Rich Embedded Computer Sports Advanced Graphical User Interface
The QVGA ControllerTM is a state-of-the-art real time embedded
computer with an advanced operator interface. It's an ideal "brain" and a front panel for instruments that need a highly visible graphical user interface (GUI), touchscreen
monitor, computational power, I/O, and serial communications - all in one compact
package. 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 scientific
instruments, machine or process control, or as an advanced operator interface for existing products. Its real-time multitasking operating system (rtos) facilitates concurrent functioning of its user interface, I/O, and application software. You may
use this compact, integrated device as the core hardware, software and user interface
for your new products - wherever you need an I/O-rich computer and an instrument front panel with advanced user interface.
Embedded dynamic web server
Turn your instrument into an embedded webserver by adding Mosaic's EtherSmart Wildcard, or a WiFi Wildcard - 2x2.5" modular boards which stack directly onto the QVGA Controller board. These Wildcards enable communications between your instrument and other computers or peripherals on the network. The EtherSmart/WiFi Wildcards implement a dynamic webserver that accepts connections from your web browser, serving out static or dynamic web pages. Your application program can send emails to alert other computers on the network when significant events occur. You can even "browse into" your instrument using a browser running on an online PC to monitor the status of your instrument.
Advanced graphical user interface
The QVGA Controller features a touchscreen controlled graphical user interface.
Combining a high-contrast 6" diagonal 1/4-VGA display and high resolution analog
touchscreen, it comes complete with object-oriented menuing software that makes it
easy to control your application using buttons, menus, graphs, and bitmapped
Display your own custom graphics on a bright white-on-blue cold-cathode fluorescent (CCFL) backlit LCD. 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.
Your application's startup screen executes automatically on power-up.
Use the QVGA Controller as your instrument front panel boasting hundreds of screens, each with software configurable buttons and menus. A precoded menu manager simplifies menu-driven control, making it easy to define buttons, menus, icons, and their associated actions. With the touch or release of a button, the menu manager 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 focus on your application.
C-programmable and customizable
You can program the QVGA Controller using either the ANSI-standard C language or
Mosaic's QED-Forth language for real-time control. Its embedded firmware reduces
your time time-to-market - it comes loaded with a real-time multitasking operating
system, object oriented GUI Toolkit, and hundreds of precoded device drivers for all
I/O. 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 already preprogrammed for you. The GUI Builder program allows you to quickly design and place your buttons and graphics in a menu-based system, while generating the GUI source code for you. The real-time operating system in onboard FLASH memory manages all required initializations and automatically initializes and starts your application code.
Mix and match embedded I/O
Control dozens of analog and digital I/O lines in real time. The QVGA 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 channels, 4 high
current drivers, and two RS232/485 ports. Pre-coded I/O drivers make it easy to do
data acquisition, pulse width modulation, motor control, frequency measurement, data
analysis, analog control, PID control, and communications.
Need even more I/O? The QVGA Controller hosts Mosaic's WildcardsTM, small I/O modules for sophisticated and dedicated I/O. Stack up to eight Wildcards for: Ethernet or wireless control, GPS tracking, 16- or 24-bit resolution programmable gain A/D; 12-bit D/A; compact flash mass memory; AC or DC solid state relays; configurable digital I/O; additional RS232, RS422 or RS485; or high-voltage, high-current DC inputs and outputs.
Plenty of memory
384K Flash and 256K RAM provides plenty of room for your application code and
graphic screens. Custom controllers with 768K Flash and 640K RAM are also available.
For those really extensive applications that require lots of memory or removable data
storage, the QVGA Controller hosts compact flash cards at 64 Megabytes and greater.
Need Protection from Aggressive Environment?
Consider our Environmental Gasket to provide a tight, chemically resistant seal between your touchscreen and bezel and to prevent infiltration of dust or liquids.
