说明：  r61505w 的液晶数据手册，以及测试用的驱动程序(LCD Data Manual of r61505w and Driver for Testing)

说明：  使用2个ZigBee节点组网，A做协调器，B做终端节点，PC机通过串口连接A,A协调器通过串口（发送命令）操控B终端节点写入和读取NV数据，NV数据为B终端节点指示灯的闪烁的时间间隔。(Two ZigBee nodes are used to form a network, A is used as coordinator, B is used as terminal node, PC is connected to A through serial port, A coordinator controls B terminal node to write and read NV data through serial port (sending commands). NV data is the flashing time interval of B terminal node indicator.)
