射频芯片cc2420的使用例程

/*******************************************************************************************************
 一对运行此程序的节点之间建立起一个使用通道26的点对点的RF连接。
 使用下面的节点地址：
 * - PAN ID: 0x2420 (both nodes)                                                                       *
 * - Short address:                                                                                    *
 *		0x1234
 *		0x5678
 * INSTRUCTIONS:                                                                                       *
 * Data packets containing a 5-byte payload will be transmitted when the pot meter is turned, or S2 is *
 * held down. The first byte of the payload contains the pot meter value, which is used to control the *
 * PWM duty cycle on the receiving node. The other bytes are random (never initialized).               *
 *                                                                                                     *
 * LED indicators:                                                                                     *
 *     - Red:    Transmission failed (acknowledgment not received)                                     *
 *     - Yellow: Transmission OK (acknowledgment received)                                             *
 *     - Orange: Remote controlled dimmer															   *
 *     - Green:  Packet received                                                                       *
