X-Board v2 and Pachube data on LCD

/*
 Demonstration sketch for X-Board by DFRobot ( http://www.dfrobot.com/index.php?route=product/product&filter_name=dfr0162&product_id=564 ) and Adafruit i2c/SPI LCD backpack
 using MCP23008 I2C expander( http://www.ladyada.net/products/i2cspilcdbackpack/index.html )

  The circuit:
 *  5V to X-Board 5V pin
 * GND to X-Board GND pin
 * CLK to X-Board #5
 * DAT to X-Board #4
