Takehiko Shimojima / AmbientLib

Ambient library. It provides "set" function to set data to a packet and "send" function to send the packet to the Ambient server. It also provides "bulk_send" function to send multiple data.

Detailed Description

Ambient class to send data to Ambient service.

Exsample: 

 #include "mbed.h"
 #include "EthernetInterface.h"
 #include "Ambient.h"
 #include "HDC1000.h"
 
 unsigned int channelId = 100;
 const char* writeKey = "ライトキー";
 Ambient ambient;
 
 HDC1000      hdc1000(p9,p10);
 
 int main() {
     printf("start\r\n");
 
     EthernetInterface eth;
     eth.init(); //Use DHCP
     eth.connect();
 
     TCPSocketConnection socket;
     ambient.init(channelId, writeKey, &socket);
 
     printf("Ambient send to ch: %d\r\n", channelId);
 
     while (true) {
         float temp, humid;
         char tempbuf[12], humidbuf[12];
 
         hdc1000.get();
         temp = hdc1000.temperature();
         humid = hdc1000.humidity();
 
         sprintf(tempbuf, "%2.1f", temp);
         ambient.set(1, tempbuf);
         sprintf(humidbuf, "%2.0f", humid);
         ambient.set(2, humidbuf);
         printf("Temp: %s C, Humid: %s %%\r\n", tempbuf, humidbuf);
         
         ambient.send();
         
         wait(30.0);
     }
 }
