TouchPanel Controller PROTO-Karte
TouchPanel Controller PROTO-Karte
Overview
Mit dem TouchPanel Controller PROTO Board können Sie Ihr Prototypgerät an ein Touch Panel anschließen. Auf dem Board befindet sich außerdem ein Touch Panel Controller mit Anschluss.
Resistive Touch-Screen Concept
A resistive touch screen is fabricated with two transparent, flexible sheets coated with a conductive material stacked on top of each other, separated by an air gap. When pressure is applied by a finger or a stylus on the screen, the top layer makes contact with the lower layer. When a voltage is applied across one of the layers, a voltage divider is created. The coordinates of a touch can be found by applying a voltage across one layer in the Y-direction and reading the voltage created by the voltage divider to find the Y-coordinate, and then applying a voltage across the other layer in the X-direction and reading the voltage generated by the voltage divider to find the X-coordinate.
Board Connections
Using a 1x6 connector CN1, the TouchPanel Controller PROTO can be connected to a port of the development system. On the other hand, the connection between a touch panel and the TouchPanel Controller PROTO is established using the connector CN2.
