# IRext Win32 Example

A Windows desktop example demonstrating the IRext infrared decoder library.

## Overview

IRext is an open-source infrared remote control library. This example provides a command-line application to test IR decoding functionality on Windows.

## Features

- Decode IR binary files for air conditioners (AC)
- Decode IR binary files for TV devices
- Query supported AC modes, wind speeds, swing options, and temperature ranges
- Generate IR timing data for remote control signals

## Requirements

- **Operating System**: Windows 10 or later
- **IDE**: Visual Studio 2019 or later
- **Build Tools**: MSVC v142 (VS2019) or v143 (VS2022)

## Building

1. Open `IRextWin32Example.sln` in Visual Studio.

2. If you encounter build error `MSB8020` (Platform Toolset not found), retarget the solution:
   - Right-click the solution in Solution Explorer
   - Select **Retarget solution**
   - Choose an installed Windows SDK and Platform Toolset

3. Select the desired configuration (`Debug` or `Release`) and platform (`x86` or `x64`).

4. Build the solution (`Ctrl+Shift+B` or **Build > Build Solution**).

## Usage

1. Run the compiled executable from the command line.
2. The program will prompt you to input key codes to simulate remote control actions.
3. Key code reference: https://site.irext.net/doc#keymap
4. Enter `99` to exit the program.

### Example Key Codes

| Key Code | Function                    |
|----------|-----------------------------|
| 14       | Query supported modes       |
| 15       | Query supported wind speeds |
| 16       | Query temperature range     |
| 99       | Exit program                |
