==Modes and protocols==
This is a summary of the USB IR Toy modes and protocols.

===IRman-compatible decoder===
The IR Toy default mode is a simple [http://www.raphnet.net/divers/documentation/irman_protocol.txt IRman compatible] USB remote control decoder. Command your PC from a remote control with [http://www.lirc.org/ lirc]/[http://winlirc.sourceforge.net/ WinLIRC], [http://www.eventghost.org/ Event Ghost], [http://www.pcremotecontrol.com/software/pcrcsoft.htm PC Remote Control], [http://www.promixis.com/ Girder], etc. The LED will blink very briefly each time it decodes an IR signal.

===Infrared sampling mode===
Infrared sampling mode times the duration of infrared pulses and sends the measurements to the computer. It's used by the custom IR Toy [http://winlirc.sourceforge.net/ WinLIRC] plugin. Includes a transmit function.

===Logic analyzer mode (SUMP)===
The IR Toy captures and displays remote control waveforms with the [http://www.sump.org/projects/analyzer/client/ SUMP open source logic analyzer client]. Sampling is triggered by a change on the IR receiver, it won't start capturing until it gets a valid IR source. The logic analyzer mode currently operates at 10kHz with a fixed 1024 sample buffer.

===Raw infrared transmit/receive (IRIO) mode===
''IRIO mode has been abandoned in favor of IR sampling mode. It still works, but it will not be enhanced in the future.'' 

IRIO is a raw infrared input/output mode, it sends and receives raw IR waveforms. This mode can clone remote controls, and playback the signals to operate devices from a computer.

===USB to serial bridge mode===
Firmware v08+ includes a USB to serial bridge mode. Serial IO on the UART header pins is converted to USB. The virtual serial port configuration determines the speed and settings.

===Self-test===

The IR Toy has a self-test that can help determine if everything is working correctly.
