1. Kit Contents
TheCP2501 Evaluation Kit contains the following items:
2. Introduction
The CP2501 is a programmable, 8051-based bridge device that adds a HID-compliant USB touch-screen interface
to multi-touch devices such as digitizers, touch screens and pens. The CP2501 devices are pre-programmed with
an easy-to-use firmware API, called the System Firmware, to perform USB communication and interface to touch
modules using UART, SPI, or SMBus.
The purpose of the CP2501 evaluation board is to demonstrate the interface capabilities of the CP2501 devices.
The CP2501 evaluation board enumerates as a touch-screen device on Windows machines and supports two-
finger multi-touch operation. The CP2501 evaluation board is shown in Figure 1.
2.1. How To Use The Evaluation Board
Connect the USB cable to the bottom-left USB connector (P2) and then to a Windows PC that supports touch-
screens. The touch-screen is mapped directly to the desktop. Placing a finger on a location on the evaluation board
screen translates to touching the same point on your desktop. Since the evaluation board touch-screen is a
different size than your monitor and not directly overlayed, it might take some time to get adjusted. Applications
such as Internet Explorer that support gestures for scrolling the page are good for testing the evaluation board. The
evaluation board is meant to show how a CP2501 can provide an HID touch-screen interface for any touch-screen
module. See Section 6 for a listing of Windows operating system versions that support touch-screens.
