SparkFun Spark Phant Library

A Phant library for the Spark Core and Photon.

Create a Phant Stream

Visit data.sparkfun.com to create a Phant stream of your own. You'll be given public and private keys, don't lose them!

If you want to set up Phant on a server of your own, visit phant.io.

Include & Constructor

Make sure you include "SparkFun-Spark-Phant/SparkFun-Spark-Phant.h":

// Include the Phant library:

#include "SparkFun-Spark-Phant/SparkFun-Spark-Phant.h":

Then create a Phant object, which requires a server, public key and private key:

const char server[] = "data.sparkfun.com"; // Phant destination server const char publicKey[] = "DJjNowwjgxFR9ogvr45Q"; // Phant public key const char privateKey[] = "P4eKwGGek5tJVz9Ar84n"; // Phant private key Phant phant(server, publicKey, privateKey); // Create a Phant object

Adding Fields/Data

Before posting, update every field in the stream using the add([field], [value]) function. The [field] variable will always be a String (or const char array), [value] can be just about any basic data type -- int, byte, long, float, double, String, const char, etc.

For example:

phant.add("myByte", 127); phant.add("myInt", -42); phant.add("myString", "Hello, world"); phant.add("myFloat", 3.1415);

POSTing

After you've phant.add()'ed, you can call phant.post() to create a Phant POST string. phant.post() returns a string, which you can send straight to a print function.

Most of the time, you'll want to send your phant.post() string straight out of a TCPClient print. For example:

TCPClient client; if (client.connect(server, 80)) // Connect to the server { client.print(phant.post()); }

After calling phant.post() all of the field/value parameters are erased. You'll need to make all of your phant.add() calls before calling post again.
