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-recognized signals may be saved and re-transmitted as raw data.
- Initial version.
| 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. |
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 can understand them.
See Universal Remotes for more information.
- Initial version.
See Infrared Unit Tests for various examples.
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.
- Initial version.
| 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. |
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. Also used as the expected encoder output. |
| decoder_expected | parsed_array | An array of parsed signals containing the expected decoder output. 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. |
