Quick Start Guide EVBCRTOUCH Xtrinsic CRTouch Capacitive and Resistive Touch-Sensing Platform Evaluation Board Xtrinsic READY PLAY SOLUTIONS Quick Start Guide Get to Know the EVBCRTOUCH Evaluation Board USB2SER Power On/Off 2 CRTouch Communication Ports Four Capacitive Electrodes Four- and Five-Wire Connectors READY PLAY SOLUTIONS Xtrinsic CRTouch EVBCRTOUCH The Xtrinsic capacitive and resistive touch-sensing platform (CRTouch) enables resistive touch screens to handle two-touch gesture recognition and allows the addition of up to four capacitive electrodes to your system, all packaged on a 5 x 5 mm 32-pin QFN. It supports four- and five-wire touch screens and communicates over UART and I2C communication protocols. The implementation of these technologies enables the CRTouch to help reduce space, cut software development costs and speed time to market. Features • Standard X, Y resistive touch screen detection with optional calibration • Pressure detection on four-wire resistive touch screens • 1 6-sample FIFO with watermark to generate an asynchronous event • Slide gesture detection for single touch • Two-touch gesture detection for resistive four-wire screens Zoom in/out Rotate • F our capacitive electrodes independent from touch screen may be configured as: Keypad Rotary Slider • I²C and UART communication Two selectable I²C slave addresses UART baud rate auto detection mechanism • Event and touch indicators for main host processor • W ake up by resistive touch, capacitive electrode touch, external pin and serial communications • N ormal run, sleep and shutdown modes for reduced power consumption • Linux® and Android™ integration example code available 3 Quick Start Guide Step-by-Step Installation Instructions In this quick start guide, you will learn how to set up the EVBCRTOUCH board. 1 Unpack and Verify Package Contents Ensure the EVBCRTOUCH touchsensing platform evaluation board package includes: • • • • • • 2 Xtrinsic CRTouch board Resistive screen Quick start guide Four-wire cable extension USB cable Stylus Install the GUI Setup Software Go to freescale.com/CRTouch and download the latest GUI software version. Follow the on-screen instructions to install the communication driver for the tool. Check back occasionally for software updates. 4 3 Connect the USB Cable and the Resistive Screen Connect your computer to the evaluation board via the included USB cable. Connect the resistive screen to the board. Power-up the board using the power switch. READY PLAY SOLUTIONS 4 Run the GUI Software and Verify Communication Open and run the GUI software. From the port settings window, select the COM port assigned to the evaluation board on your computer. Press the resistive screen and then click on the Read button. If the X and Y coordinates registers are updated in the CRTOUCH Settings window, you are ready to use the EVBCRTOUCH evaluation board. 5 Quick Start Guide EVBCRTOUCH Jumper Options The following is a list of all jumper options.
