Get decoder instance:

IRDecode irDecoder = IRDecode.getInstance();

Load AC binary file:

irDecode.openACBinary(binFileName);

Load TV binary file:

irDecode.openTVBinary(binFileName, subCategory);
// subCategory is 'sub_cate' property of your downloaded remote index

Decode AC control command:

irDecode.decodeACBinary(acStatus, acFunction);
// ACStatus refers to the current state of Air conditioner, please check ACStatus.java for information

Decode TV control command:

irDecode.decodeTVBinary(keyCode)
// For key definition, please refer to http://irext.net/doc/index.html

Close AC binary file:

irDecode.closeACBinary();

Close TV binary file:

irDecode.closeTVBinary();

Get AC supported modes:

int []supportedModes = irDecode.getACSupportedMode();

Get AC supported temperature range in a certain mode:

TemperatureRange tr = irDecode.getTemperatureRange(mode);

Get AC supported wind speed levels in a certain mode:

int []windLevels = irDecode.getACSupportedWindSpeed(mode);
