##ROS driver for power

How to use xpkg_XXX(XXX is your device) ros driver
=====================================================================
        1) Clone this ros package folder(xpkg_XXX) to your catkin's workspace src folder
        2) Run catkin_make to build
        3) Add path of setup.bash to ~/.bashrc like: echo "source ~/workspace/devel/setup.bash">> ~/.bashrc	source ~/.bashrc
        4) Change parameters in xnode_XXX_test.launch(xpkg_XXX/launch/xnode_XXX_test.launch)
        6) prepare xpkg_comm and Roslaunch xnode_comm.launch(xpkg_comm/launch/xnode_comm.launch)
        7) Roslaunch xnode_XXX_test.launch(xpkg_XXX/launch/xnode_XXX_test.launch)
        8) Use topic /xpkg_XXX/ctrl_json to control sensor function

Note
=====================================================================
        1) When device connect successfully,ros will print out:"xnode_XXX: device online"
        2) When device enable successfully,ros will print out:"xnode_XXX: device enable"
        3) When device ready,ros will print out:"xnode_XXX: device init finish"
        4) Don't Change parameter of "ini_path"
        5) This node will publish message "/xtopic_XXX/device_state_json" and "/xtopic_comm/com_send_xstd"
        6) Must run with xpkg_comm

Special note: please use include/LIB_JSON/ArduinoJson.h,view < https://arduinojson.org > for details
