BREAKING CHANGE: API changed significantly, see doc/Migrating to the new API.md.

Requires Arduino IDE 1.0.6 or above.

ArduinoJson 4.0 beta 1

Changes compared to 3.4:

• Unified parser and generator API (issue #23)
• Updated library layout, now requires Arduino 1.0.6 or newer

BREAKING CHANGE: API changed significantly, see doc/Migrating to the new API.md.

ArduinoJson 3.4

Changes compared to 3.3:

• Fixed escaped char parsing (issue #16)

How to install?

To use this library with the Arduino IDE, you need to unzip the attached file into

<path_to_your_sketches>/libraries/

ArduinoJson 3.3

Changes compared to 3.2:

• Added indented output for the JSON generator, see example bellow.
• Added IndentedPrint, a decorator for Print to allow indented output

Example:

JsonOject<2> json;
json["key"] = "value";
json.prettyPrintTo(Serial);

ArduinoJson 3.2

Changes compared to 3.1:

• Fixed a bug when adding nested object in JsonArray (bug introduced in v3.1).

ArduinoJson 3.1

Changes compared to 3.0:

• Calling Generator::JsonObject::add() twice with the same key now replaces the value
• Added Generator::JsonObject::operator[], see bellow the new API
• Added Generator::JsonObject::remove()

Old generator API:

JsonObject<3> root; 
root.add("sensor", "gps");
root.add("time", 1351824120);
root.add("data", array);

New generator API:

JsonObject<3> root; 
root["sensor"] = "gps";
root["time"] = 1351824120;
root["data"] = array;
