A high-level Java API for interaction with Denon Audio Video receivers via TCP/IP

denon4j Java API

The denon4j project provides a higher level Java API for communicating with a Denon audio video receiver (currently only AVR1912 is tested) via TCP/IP. It hides the complexity of the network receiver and provides generic controls that can be used with every Denon receiver.

The project is intended to be easily extended for those who want to write an API for their own AVR model.

Contributions are welcome!

Prerequisites

• Java 8
• Maven 3.2+ (only for building)
• You must be connected to the same network as your AV receiver
• Your receiver must be either turned on or you have to enable the network standby feature

Basic API Usage

Avr1912 avr = new Avr1912(192.168.0.102, 23);
avr.connect(1000);
Slider masterVolume = avr.masterVolume();
masterVolume.slideUp();
avr.disconnect();

Take a look at the class Demo.java in the test directory to view a complete example.

Command line usage

java -jar denon4j-[version]-cli.jar 192.168.0.12 23
Enter a command ('?' for help, 'q' for quit):
> ?

The following options are available:

?			Prints this help
q			Quits the program
<cmd>		Executes a generic command e.g. PW?
PW?			Returns the power state
PWON		Turns power on

See the Denon AVR receiver for a full list of commands.
> MU?
OFF

About the API

• All packages which have 'internal' in their name are not intended to be used from outside
• Changes to internal packages are made without further notice

Building

This is a maven style project so mvn needs to be on your $PATH. To build from scratch just type:

mvn clean package
