# ArduinoCIR: Communication using consumer IR "remote" signals

(Send/receive "TV remote" (+satbox +...) commands)



## Description

ArduinoCIR provides the `ir_messaging` library, a ready-to-use solution for sending/receiving consumer IR (remote-control) signals on Arduino platforms.



## Features

 - **Simultaneously** transmit & receive IR messages.

 - **(Untested)**: Build solutions supporting 2+ receivers or 2+ transmitters (Speed & hardware permitting).

 - User-selectable hardware units for timers (not hard-coded in library).



### Supported Protocols

The list of supported protocols is listed below.

- **NEC**: (tx/rx).

- **RC-MM**: (tx only).

- **RC-5**: (untested tx/untested rx).

- **Sony SIRC**: (untested tx/rx).

Note:

 - Certain protocols might only be implemented for *either* transmit (tx) or receive (rx).

 - New protocols can be added to [libraries/ir\_messaging/ir\_protocol.cpp](libraries/ir_messaging/ir_protocol.cpp)/[.h](libraries/ir_messaging/ir_protocol.h).

### Supported Hardware

ArduinoCIR was designed to support easily multiple Atmel platforms.  At the moment, only a few are actually implemented:

 - Atmel ATmega328/328P

   - Arduino Uno

   - Arduino Redboard (✅ Tested)

   - Arduino Pro

   - Arduino Fio

   - Arduino Mini

   - Arduino Nano

   - Arduino LilyPad

   - Arduino BT

   - Arduino Ethernet

 - Atmel ATmega1280

   - Arduino Mega

 - Atmel ATmega2560

   - Arduino Mega 2560 (✅ Tested)

   - Arduino Mega ADK (✅ Tested)



## Known Limitations

 - IR receiver currently only works using a 16-bit timer (`IRCtrl::Timer16b::RxHw`).

 - IR transmitter currently supports two resource allocations:

   - System clock (Timer0) + an 8-bit timer (`IRCtrl::Timer8b::TxHw`),

   - or *two* 16-bit timers (`IRCtrl::Timer16b::TxHw`).

### Compatibility

The `ir_messaging` library was tested on version 1.0.5+dfsg2-2 (Linux) of the Arduino IDE.
