Freescale EVBCRTOUCH Touch Sensing Platform Evaluation Board

Touch Sensing Platform Eval Board

Freescale EVBCRTOUCH Touch Sensing Platform Evaluation Board is a low cost development board that allows quick connection between any standard 4- and 5-wire resistive screen. This Freescale evaluation board also features four capacitive electrodes, enabling a quick ramp up. The EVBCRTOUCH board also provides a USB to Serial bridge to allow a connection to any host Processor or PC via USB. The integrated CRTOUCH resistive touch screen controller enables 4-wire resistive touch screens to handle basic gesture recognition. CRTOUCH also allows the addition of up to 4 capacitive electrodes to your system. It supports 4-wire and 5-wire touch screens and communicates over UART and IIC communication protocols.

  • Standard X,Y resistive touch screen detection with optional calibration
  • Pressure detection on 4 and 5 wires
  • 16 samples FIFO with watermark
  • Gesture detection:
    • Slide
    • Two touch pinch and expand
    • Two touch rotate
  • 4 capacitive electrodes independent from touch screen:
    • 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
  • Wake by single touch, double touch, gestures or capacitive electrodes activity
  • Low power consumption
  • Linux and Android integration example code available
