【WirelessSersorMS - 物联网环境监测项目】
树莓派开发系列文章
项目名称
中文名称：基于 Zigbee 协议的物联网环境监测项目
英文名称：Wireless Sensor Monitoring System
简称：WirelessSersorMS
项目介绍
项目以 Zigbee 为通讯协议，基于 CC2530 开发的协调器和多个终端节点进行组网，并将接收到的环境传感器数据通过串口发送到树莓派 Linux 主控。
用户可通过其他 Linux 客户端、安卓 APP 访问树莓派主控，下发指令给协调器，远程控制终端节点硬件，采集环境信息，监控视频画面；同时，树莓派主控支持用户远程注册、登录、查询数据库，以及通过 socket 连接下载日志和数据文件。
应用技术
Zigbee 通讯协议（IEEE 802.15.4 低速率无线个域网（LR-WPAN）协议）
Linux系统编程，多线程开发，串口传输，socket编程，客户端、服务端开发
CC2530 驱动开发

PC识别串口方法
如果该串口被PC获取，名字为COMn【n为某整数】。
Ubuntu识别串口方法
首先需要vmware抓取串口【串口在同一时刻要么被windows抓取要么被vmware抓取】，按下图所示，点击连接即可。
但是往往ubuntu中没有ch340的驱动，经过实际测试，ubuntu14及之前的版本都没有这个驱动，ubuntu16以上的版本有这个驱动。
如果没有ch340驱动可以用以下方法安装对应的驱动：
make
sudo make load
ls /dev/ttyUSB0
按照上述步骤，会生成设备文件/dev/ttyUSB0。
ls /dev/ttyUSB0 -l
crw-rw---- 1 root dialout 188, 0 Jan 15 05:45 /dev/ttyUSB0
项目模块设计（以串口模块为例）
1. 信令
上位机和下位机的通信往往都是通过串口，linux下往往生成字符设备ttyUSB0【有的是ttyS0】，操作串口设备就只需要操作该字符设备即可。
设计上位机，首先需要设计上位机下发给下位机的指令格式，上位机按照该指令格式发送命令给下位机，下位需严格按照该指令格式进行解析指令。
含义如下：
- device：要操作的设备
- data ：对应的设备及其额外的数据
- CRC ：校验码
- # :信令终止符
信令格式可以根据需要扩展或者精简。
其中device定义如下【可以根据实际情况进行扩展】：
#define DEV_ID_LED_ON 0X1
#define DEV_ID_LED_OFF 0X2
#define DEV_ID_DELAY 0X3
#define DEV_ID_GAS 0X4
2. 上传数据
下位机需要采集传感器的数据并通过串口上传，数据结构定义如下：
struct data{
unsigned char device;
unsigned char crc;
unsigned short data;
};
- device 设备
- data 采集的数据
- crc 校验码
3. 功能模块
下位机
下位机主要任务就是循环接收上位机通过串口下发的数据，然后解析该指令内容，操作对应的硬件。
上位机
上位机主要任务是打印菜单，由用户针对菜单做出选择，然后按照指令格式封装命令，并通过串口将该命令下发给下位机。

ADCCON3 = 0x87;
/* Wait for the conversion to be done */
while (!(ADCCON1 & 0x80));
/* Disable channel after done conversion */
ADCCFG &= (0x80 ^ 0xFF);

reading = ADCH;
