The QScreen controller is a C-programmable embedded computer with a built-in graphical user interface.

Powered by an HC11 Motorola microprocessor, the QScreen is ideal for OEM applications such as embedded systems, scientific instruments, robotics, and portable data acquisition.

The QScreen controller sports a touchscreen-operated graphical user interface on a high-contrast 128 x 240 pixel display with a 5 x 4 touchscreen overlay.

It also features a real-time multitasking operating system, hundreds of precoded device drivers, and up to 1Mbyte Flash and 512Kbyte RAM.

The QScreen controller commands eight 8bit A/D lines, eight digital I/O lines including timer-controlled and PWM channels, and two RS232/485 ports.

Precoded I/O drivers are provided for all I/O, and make it easy to perform data acquisition, pulsewidth modulation, motor control, frequency measurement, data analysis, analogue control, PID control and communications.

Highly expandable, the QScreen can host up to seven Wildcards, small stackable I/O modules for sophisticated and dedicated I/O.

Available Wildcards include octal 12bit D/A and 16bit A/D convertors, a 24bit-resolution analogue data acquisition subsystem, CompactFlash card mass memory interface, fast buffered RS232/485 dual UART, high-voltage/high-current isolated I/O, and AC or DC solid-state relays.

The QScreen controller is priced at $359.00 in hundreds.
