  • How to Use TI's 4-Wire TSC to Control an 8-Wire Resistive Touch Screen
    PDF, 271 Kb, Datei veröffentlicht: Mar 27, 2006
    This application report implements a Texas Instruments 4-wire touch screen controller (TSC) to control an 8-wire touch screen and discusses features and performances for such applications.Texas Instruments (TI) provides various TSC devices for the 4-wire or 5-wire touch screens (TS). A TI 4-wire TSC device, such as the ADS7843, TSC2003, or TSC2046, is ideal for controlling a 4-wire TS, but it
  • ADS7843 Pen Interrupt
    PDF, 48 Kb, Datei veröffentlicht: Sep 27, 2000
    The ADS7843 is a 12-bit sampling analog-to-digital converter (ADC) used to drive 4-wire touch-screens to serial interfaces by ratiometrically converting two differential input signals. The ADS7843 also produces an accurate output with the first conversion cycle once powered up.

  • 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

  • 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
