The Intel SA-1110 StrongArm processor is a popular platform for development of personal digital assistants (PDAs) and other hand-held computing devices. The human interface for these devices is generally a touch screen. This application report provides information on connecting the TI ADS7846 touch screen controller to an SA-1110, and provides documentation for a Windows CE driver that has been de - Operation Schemes of Touch Screen ControllersPDF, 846 Кб, Файл опубликован: 21 май 2007
- Apply TI TSC for Various and Multiple FunctionsPDF, 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 - 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 - Set Up and Use TSC TimingsPDF, 271 Кб, Файл опубликован: 7 июн 2007
This application report helps users to understand, set up, and use the programming timings in the register-based touch screen controller (TSC) devices. It displays the timings functions and discusses the effect on the system interface traffic and on the system power consumption. - PCB Layout Guideline for TI Resistive TSC DevicesPDF, 144 Кб, Файл опубликован: 4 окт 2012
