  • Apply TI TSC for Various and Multiple Functions
    PDF, 316 Kb, Datei veröffentlicht: Dec 11, 2006
    This application report presents several examples showing how a touch screen controller (TSC) from Texas Instruments provides a variety of functions such as graphs, scroll bars, pressure buttons, and analog dials. A simple resistive TSC can be used to achieve all of these functions as long as they are not activated simultaneously. This application report demonstrates a few simple examples how th
  • Reducing Analog Input Noise in Touch Screen Systems (Rev. A)
    PDF, 535 Kb, Revision: A, Datei veröffentlicht: Sep 15, 2007
    This application report discusses some common methods for reducing noise in the analog input circuitry of a resistive touch screen controller. In terms of hardware design, PCB layout and grounding are critical; the additional noise-decoupling capacitor built into a touch screen controller input pin may also help. On the software side, several simple, widely-applied filtering algorithms are present
