• 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)
