Introduction
WiseSnail is the short name of Wise Sensor Network Abstract Interactive Layer. It is a layer to define the topology and behavior of sensor network. A complete device represented in WiseSnail includes one virtual gateway, one sensor connectivity interface and several sensor hubs. WiseSnail provides a form-like array which we call it infospec array to define tha parameters of sensor hub. And a form-like data array updates your real time data. So, you can easy to represent your device by creating several arrays.
OS
- Ubuntu 14.04
- OpenWRT
Requirements
Configure
This library uses autoconf and automake to handle the makefile system.
Optional
| --disable-paho: | Disable Paho support. |
| --disable-mosquitto: | Disable Mosquitto support. |
Compile
You can perform the following steps to build this library.
./configure Or ./configure --host=<your cross compiler> --prefix=<install path> make make install
Structures
Infospec
| Description
The infospec structure defines your parameters in sensor hub. Those parameter structures will represented in Wise-Paas like a tag. this structure includes two callback functions. You can use the callbacks to define your own get and set function. The parameter button on Wise-Paas will different by whether the set function is defined or not. If the set function is defined, the value is writeable by users on Wise-Paas. |
struct WiseSnail_InfoSpec{
WiseSnail_DataType type;
char *name;
char *unit;
union {
float value;
char *string;
};
float min;
float max;
char *resourcetype;
WiseSnail_SetValue setValue;
WiseSnail_GetValue getValue;
};
|
| Example |
{
WISE_VALUE, //WiseSnail_DataType
"Temperature", //name
"Cel", //unit
0, //value or string
-100, //min
200, //max
"ucum.Cel", //resourcetype, optional
NULL, //set function
NULL //get function
}
|
Data
| Description
The data structure defines your value you want to update in sensor hub. the cliendId and info is for internal used and will be assigned while your callback function(like set) is called. |
struct WiseSnail_Data{
WiseSnail_DataType type;
char *name;
union {
float value;
char *string;
};
char *clientId; //internal
WiseSnail_InfoSpec *info; //internal
}
|
| Example |
{
WISE_VALUE, //WiseSnail_DataType
"Temperature", //name
100 //value or string
}
|
Callbacks
| Set Callback |
typedef int (*WiseSnail_SetValue)(WiseSnail_Data *data); |
| Get Callback |
typedef int (*WiseSnail_GetValue)(WiseSnail_Data *data); |
