A. Download the udev rules file.
    1. 到 Downloads · ytai/ioio Wiki , 下載 Linux 版的檔案: 50-ioio.rules (另存新檔)
       其內容為:
ACTION=="add", SUBSYSTEM=="tty", SUBSYSTEMS=="usb", ATTRS{idVendor}=="1b4f", ATTRS{idProduct}=="0008", SYMLINK+="IOIO%n", MODE="666"
ATTRS{idVendor}=="1b4f", ATTRS{idProduct}=="0008", ENV{ID_MM_DEVICE_IGNORE}="1"

    2.  將 50-ioio.rules 上傳到 pi 裡:
         $ scp 50-ioio.rules pi@192.168.1.24:/home/pi

    3. copy it to your rules directory (one time step)
       $ sudo cp 50-ioio.rules /etc/udev/rules.d

    4. restart udev
       $ sudo restart udev
       (or $ sudo /etc/init.d/udev restart)

-----------------------------------------------------------------------------------------------

B. Check IOIO recognized status
    1. Plug your IOIO into a free USB port on the Raspberry Pi

    2. check if it’s recognized using this command
        $ ls /dev/IOIO*
           /dev/IOIO0

-----------------------------------------------------------------------------------------------

C. Install Java on your Pi
    1. for pi 1:
        $ sudo apt-get install openjdk-7-jre

    2. for pi 2:
       $ sudo apt-get install openjdk-8-jre

    3. 備註:
        切換使用不同版本的 java 方式: (如果有安裝不同的版本)
        $ sudo update-alternatives --config java

-----------------------------------------------------------------------------------------------

D. 安裝 avahi-daemon
    $ sudo apt-get install avahi-daemon

-----------------------------------------------------------------------------------------------

E. Check PIXEL recognized status
    1.Move the toggle switch on the side of PIXEL from the “Bluetooth” position to the “PC” position

    2. Plug PIXEL into a free USB port on your Raspberry Pi using the included USB A-A cable.

    3. Then check if it’s recognized using this command:
        $ ls /dev/ttyACM0*
           /dev/ttyACM0

-----------------------------------------------------------------------------------------------

F. 下載 PIXEL Console App
        http://ledpixelart.com/console/
    1. 在此使用 PIXEL: Console V2.0 版本
    2. 上傳到 pi 裡:
        $ scp pixelc_2_0.jar pi@192.168.1.24:/home/pi

-----------------------------------------------------------------------------------------------

G. 測試:
     先將 pixelc_2_0.jar  更名成: pixelc.jar
     1. $ java -jar -Dioio.SerialPorts=/dev/IOIO0 pixelc.jar --gif=black.gif
     2. $ java -jar -Dioio.SerialPorts=/dev/IOIO0 pixelc.jar --gif=black.gif --write
     3. $ java -jar -Dioio.SerialPorts=/dev/IOIO0 pixelc.jar -–zip=95050
     4. $ java -jar -Dioio.SerialPorts=/dev/ttyACM0 pixelc.jar --gif=black.gif
     5. $ java -jar pixelc.jar --gif=fire.gif
     6. $ java -jar pixelc.jar -–zip=95050 

-----------------------------------------------------------------------------------------------
