Application Notes

  • Set Up and Use TSC Timings
    PDF, 271 Kb, File published: Jun 7, 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.
  • Evaluating the ADS7846E: Using the DEM-ADS7843E/45E Evaluation Fixture
    PDF, 44 Kb, File published: Sep 27, 2000
    The ADS7846 is the next-generation version to the industry standard ADS7843 4-wire touch-screen controller. The ADS7846 is 100% pin-compatible with the existing ADS7843, and will drop into the same socket. This allows for easy upgrade of current applications to the new version.
  • Using the ADS7846 Touch Screen Ctrl. with the Intel SA-1110 StrongArm Processor
    PDF, 81 Kb, File published: Sep 19, 2001
    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
  • Using a touch-screen controller’s auxiliary inputs

  • Reducing Analog Input Noise in Touch Screen Systems (Rev. A)
    PDF, 535 Kb, Revision: A, File published: 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
