AndroidInfrared
Android Infrared is a infrared library drives IR LED built in Samsung devices, such as S4, Note 3.
Protocol Supported
Android Infrared supports most of popular protocols avaiable nowadays, including:
- NEC
- Sony
- RC5
- RC6
- DISH
- Sharp
- Panasonic
- JVC
Code Sample
// Create ConsumerIrManager instance, which provides the unified and enhanced API across Samsung private API and KitKat API.
ConsumerIrManager manager = ConsumerIrManager.getSupportConsumerIrManager(context);
// Check whether IrEmitter is avaiable on the device.
if (!manager.hasIrEmitter()) {
Log.e("AndroidInfraredDemo", "Cannot found IR Emitter on the device");
}
// Build IR Command with predefined schemes.
IrCommand necCommand = IrCommand.NEC.buildNEC(32, 0x723F);
manager.transmit(necCommand);
// Build IR Command from Pronto code
IrCommand prontoCommand = IrCommand.Pronto.buildPronto("0000 0067 0000 0015 0060 0018 0018 0018 0030 0018 0030 0018 0030 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 0018 0030 0018 0030 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 03f6");

int FREQUENCY = 38028; // T = 26.296 us
int HDR_MARK = 342;
int HDR_SPACE = 171;
int BIT_MARK = 21;
int ONE_SPACE = 60;
int ZERO_SPACE = 21;
// Build IR Command with Builder

// Simplify Sequence building process by using Sqeuence Definition

.pair(HDR_MARK, HDR_SPACE) // Lead-in sequence
.sequence(necSequence, 8, 0xFC000000) // As same as previous one
.mark(BIT_MARK) // lead-out sequence
.build();
// Build IR Command from Raw Data
int[] sequence = IrCommandBuilder.buildRawSequence(

BIT_MARK, ONE_SPACE, // 1
BIT_MARK, ONE_SPACE, // 1

);
manager.transmit(40000, sequence);
Sister Project
To decode and record the ir code from a existing remote control, such as TV remote or AirCon Remote, you can try IRRecorder.
Known Issue
Android Infrared uses the Samsung customized IR Blast API, and doesn't compatible with Android 4.4 KitKat standard
ConsumerIrManager
. The Adpoting to support KitKat standard API process is already in progress.
