CC2530远程控制灯亮灭程序 -

/***********************************************************************************
网蜂ZigBee-无线点灯实验代码详细解释请参考《ZigBee实战演练》中无线电灯相关内容
实验操作：
第一步：找到下面内容，把appLight(); 注释掉，下载到发射模块。
appSwitch(); //节点为按键S1 P1_2
// appLight(); //节点为指示灯LED1 P1_0
第二步：找到相同位置，这次把appSwitch();注释掉，下载到接收模块。
//appSwitch(); //节点为按键S1 P0_4
appLight(); //节点为指示灯LED1 P1_0
完成烧写后上电，按下发射模块的S1按键，可以看到接收模块的LED1被点亮。
*********************************************************************************
Filename: light_switch.c
Description: This application function either as a light or a
switch toggling the ligh. The role of the
application is chosen in the menu with the joystick at initialisation.
Push S1 to enter the menu. Choose either switch or
light and confirm choice with S1.
Joystick Up: Sends data from switch to light
