Introduction
This manual has been written for users of the Microchip Devil Ray touch screen micro-controller board. The
TSHARC touch screen controller boards and software described within this document are assumed to be used with
four, five or eight wire analog resistive touch screen products manufactured by a variety of touch screen
manufacturers. Touch screens between manufacturers vary with regards to light transmission, sensitivity, contact
resistance, capacitance and other electrical characteristics. Because touch screen quality and electrical
characteristics may vary between touch screen technologies and manufacturers the actual, overall performance may
vary between touch screen overlay manufacturers’ products.
A great deal of attention has been paid to eliminate potential problems with various touch screen manufacturers. We
have identified substantial specification variance within each manufacturer and between manufacturers touch
screens. While most of the manufactures we tested did fall within a functional specification, it is important to request
electrical and mechanical specifications from your touch screen overlay manufacturer to insure uniform quality and
performance. The specification details that should be provided by your touch screen overlay supplier include lead to
lead resistance, sheet resistance, and linearity of ITO.
Product Description
Standard TSHARC Devil Ray controller board auto-detects and configures for RS-232 and USB communications and
manufacturers’ 4, 5 or 8 wire analog resistive touch screens.
Firmware revision may be specified as a “Special Order”. If firmware is not specified, the latest firmware revision will
be supplied with all TSHARC? Devil-Ray controller boards ordered.
