This repository is archived and if you need a similar library you can use the CayenneLPP library.

CayenneLPPDecode

This is an Arduino Library Compatible to Decoder Cayenne Low Power Payload to Json format (ArduinoJson).

Dependences

This library uses the ArduinoJson library.

Installation

Documentation

Examples

The library comes with examples. After installing the library you need to restart the Arduino IDE before they can be found under File > Examples > CayenneLPPDecode.

Quickstart

CayenneLPP Input

lpp.addDigitalInput(1, 0);
lpp.addDigitalOutput(2, 1);
lpp.addAnalogInput(3, 1.23f);
lpp.addAnalogOutput(4, 3.45f);
lpp.addLuminosity(5, 20304);
lpp.addPresence(6, 1);
lpp.addTemperature(7, 26.5f);
lpp.addRelativeHumidity(8, 86.6f);
lpp.addAccelerometer(9, 1.234f, -1.234f, 0.567f);
lpp.addBarometricPressure(10, 1023.4f);
lpp.addGyrometer(1, -12.34f, 45.56f, 89.01f);
lpp.addGPS(1, -12.34f, 45.56f, 9.01f);
