A Systematic Approach To Verify An Embedded Capacitive Touchscreen System, Jeffrey Lee Richardson

Boise State University Theses and Dissertations

The conspicuously massive growth in the number of products utilizing capacitive touchscreen technology has raised awareness of the technology. The embedded system used to detect and report finger touches to the host is fairly complex and difficult to verify. An automated verification system is required to systematically test this type of system in a reasonable amount of time. This thesis describes the framework for an automated verification system for embedded capacitive touchscreen systems. The framework includes a Cartesian desktop robot, test instruments, communications bridge, and custom-built test management software. The criteria for selecting a Cartesian desktop robot rather than a …
