总结下总体的流程

1.系统初始化

2.外设时钟使能:IOCON,GPIO0

3.看门狗初始化,启动看门狗

4.读取ip,电话号码,节点信息

4.按键.LED,串口,定时器.ZigBee初始化

5.喂狗

6.EM310复位,喂狗,等待EM310初始化完成.

7.EM310初始化完成

8死循环:

1. 分支1: 按键事件:----------------处理按键,然后喂狗.
2. 分支2:响铃事件---------------------处理短信|电话,然后喂狗.
3. 分支3:GPRS连接-----------------------串口:来自ZigBee|GPRS发到ZigBee
4. 分支4:定时器中断----------------保存节点信息.
5. 喂狗

究竟有哪些事情要做?

按键---->复位LPC

短信|电话---->配置网关

定时器中断--->保存节点信息

==>重点是: PRS

在GPRS分支里,所有数据放到Gprs_Buf.Buffer里

从串口FIFO里接收到数据

从GprsRevData接收数据

从GprsRevLeftData接收数据.

//问题是:这里的GPRS有两个方向?GprsRevData,GprsRevLeftData什么意思?
