Application Notes

  • How to Use TI's 4-Wire TSC to Control an 8-Wire Resistive Touch Screen
    PDF, 271 Кб, Файл опубликован: 27 мар 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 Кб, Файл опубликован: 27 сен 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.

  • Touch Screen Controller Tips
    PDF, 86 Кб, Файл опубликован: 27 сен 2000
    The ADS7843, ADS7845, and the new ADS7846 converters all are designed for specific touch screen applications. Applications using these devices can benefit greatly from the tips presented in this application bulletin. Most of the examples discuss the ADS7843, but the techniques shown are applicable to all of the devices.

  • Reducing Analog Input Noise in Touch Screen Systems (Rev. A)
    PDF, 535 Кб, Версия: A, Файл опубликован: 15 сен 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

    PDF, 316 Кб, Файл опубликован: 11 дек 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
