System Block Diagram for First Touch Multifunction Card Ambient Light Detector Blue LED Programming and Interface Connector PSoC CY8C21434 CapSense Slider RGB Clusters CapSense Proximity Sensor Thermistor FTPC Bridge (First Touch PC Bridge) The PC bridge consists of the CY8C24894 Hub. It contains a 16-pin connector to connect to the MultiFunction Board for application data exchange.The FTPC Bridge is the interface bridge between the expansion card, your PC, and the various applications.

  • Page 21: Led Usage

    Hardware 4.2.1 LED Usage Blue LED The blue LED blinks fast when the bridge is first connected to the USB port of a PC. After hot plug and play is established, it blinks at a periodic interval to indicate that the hub is enumerated and functioning normally.
  • Page 22 Hardware Note that the CY8C24894 PSoC device is the only active component in the entire circuit. This single PSoC handles all communications between the applications, USB, and expansion card interfaces. The FirstTouch expansion card connects to the FTPC bridge through the 8×2 expansion port (this is a built-in port on the bridge).

  • Page 23: Expansion Card Overview

    Hardware Expansion Card Overview The FirstTouch expansion card is designed to plug and play with the FTPC bridge. All power for the included expansion cards is provided by the FTPC bridge directly from the USB bus. No other power supply is necessary when an expansion card is connected to the FTPC bridge. Connection to the FTPC expansion port is through the 8×2 pin header on the expansion card.
  • Page 24 Hardware The FTMF expansion card uses a standard FirstTouch expansion header to connect to the First- Touch RF expansion board or other target hardware. Figure 4-5. FTMF Expansion Card Expansion Header Signals Note that the 8×2 pin expansion header also includes four GPIO connections labeled P02 to P05. These are hard wired to four unused Port 0 I/O pins on the CY8C21434 host and allow you to easily connect the FTMF expansion card to your specific hardware or sensors.
