For this demo, you need to use the:
Xadow Main Board
Connect them with FFC Cables, then you need to do some preparations that refer to the first Demo's steps. Differ from the demo1, you need to download the library:Smile and directly open SMILE INO file.
This demo functions: In normal circumstances, the OLED displays the current barometric pressure value. When you shake the Xadow Accelerometer, there will appear a smile face on the screen.
Before uploading the code：smile to Xadow main board, please make sure there are the library:OLED_Display12864 and DigitalAccelerometer_ADX345 in the Arduino Library. If not, please download them and put them on the libraries file of Arduino IDE by the path: ..\arduino-1.0.1\libraries after unzipping. Do not forget to select Seeed Xadow from the Tools | Board menu of the Arduino environment._
