Description

Filename extension: .ir

This file format is used to store an infrared remote that consists of an arbitrary number of buttons. Each button is separated from others by a comment character (#) for better readability.

Known protocols are represented in the parsed form, whereas non-recognised signals may be saved and re-transmitted as raw data.

Version history:

1. Initial version.

Format fields

Name	Use	Type	Description
name	both	string	Name of the button. Only printable ASCII characters are allowed.
type	both	string	Type of the signal. Must be parsed or raw.
protocol	parsed	string	Name of the infrared protocol. Refer to ir console command for the complete list of supported protocols.
address	parsed	hex	Payload address. Must be 4 bytes long.
command	parsed	hex	Payload command. Must be 4 bytes long.
frequency	raw	uint32	Carrier frequency, in Hertz, usually 38000 Hz.
duty_cycle	raw	float	Carrier duty cycle, usually 0.33.
data	raw	uint32	Raw signal timings, in microseconds between logic level changes. Individual elements must be space-separated. Maximum timings amount is 1024.

Infrared Library File Format

Examples

• TV Universal Library
• A/C Universal Library
• Audio Universal Library

Description

Filename extension: .ir

This file format is used to store universal remote libraries. It is identical to the previous format, differing only in the Filetype field.
It also has predefined button names for each universal library type, so that the universal remote application could understand them. See Universal Remotes for more information.

Version history:

1. Initial version.

Infrared Test File Format

Examples

See Infrared Unit Tests for various examples.

Description

Filename extension: .irtest

This file format is used to store technical test data that is too large to keep directly in the firmware. It is mostly similar to the two previous formats, with the main difference being the addition of the parsed signal arrays.

Each infrared protocol must have corresponding unit tests complete with an .irtest file.

Known protocols are represented in the parsed_array form, whereas raw data has the raw type.
Note: a single parsed signal must be represented as an array of size 1.

Version history:

1. Initial version.

Format fields

Name	Use	Type	Description
name	both	string	Name of the signal. Only printable ASCII characters are allowed.
type	both	string	Type of the signal. Must be parsed_array or raw.
count	parsed_array	uint32	The number of parsed signals in an array. Must be at least 1.
protocol	parsed_array	string	Same as in previous formats.
address	parsed_array	hex	Ditto.
command	parsed_array	hex	Ditto.
repeat	parsed_array	bool	Indicates whether the signal is a repeated button press.
frequency	raw	uint32	Same as in previous formats.
duty_cycle	raw	float	Ditto.
data	raw	uint32	Ditto.

Signal names

The signal names in an .irtest file follow a convention <name><test_number>, where the name is one of:

• decoder_input
• decoder_expected
• encoder_decoder_input,

and the number is a sequential integer: 1, 2, 3...etc, which produces names like decoder_input1, encoder_decoder_input3, and so on.

Name	Type	Description
decoder_input	raw	A raw signal containing the decoder input. Is also used as the expected encoder output.
decoder_expected	parsed_array	An array of parsed signals containing the expected decoder output. Is also used as the encoder input.
encoder_decoder_input	parsed_array	An array of parsed signals containing both the encoder-decoder input and expected output.

See Unit Tests for more info.
