Go to the documentation of this file.

/*
 Assuming the protocol we are adding is for the (imaginary) manufacturer:  Shuzu
 
 Our fantasy protocol is a standard protocol, so we can use this standard
 template without too much work. Some protocols are quite unique and will require
 considerably more work in this file! It is way beyond the scope of this text to
 explain how to reverse engineer "unusual" IR protocols. But, unless you own an
 oscilloscope, the starting point is probably to use the ReceiveDump.ino sketch and
 try to spot the pattern!
 
 Before you start, make sure the IR library is working OK:
 # Open up the Arduino IDE
 # Load up the ReceiveDump.ino example sketch
 # Run it
 # Analyze your data to have an idea, what is the header timing, the bit timing, the address, the command and the checksum of your protocol.
 
 Now we can start to add our new protocol...
 
 1. Copy this file to : ir_<YourProtocolName>.hpp
 
 2. Replace all occurrences of "SHUZU" with the name of your protocol.
 
 3. Tweak the #defines to suit your protocol.
 
 4. If you're lucky, tweaking the #defines will make the decode and send() function
 work.
 
 You have now written the code to support your new protocol!
 
 To integrate it into the IRremote library, you must search for "BOSEWAVE"
 and add your protocol in the same way as it is already done for BOSEWAVE.
 
 You have to change the following files:
 IRSend.hpp     IRsend::write(IRData *aIRSendData + int_fast8_t aNumberOfRepeats)
 IRProtocol.h   Add it to decode_type_t
 IRReceive.hpp  IRrecv::decode() + printActiveIRProtocols(Print *aSerial) + getProtocolString(decode_type_t aProtocol)
 IRremote.hpp   At 3 occurrences of DECODE_XXX
 IRremoteInt.h  Add the declaration of the decode and send function
 
 Now open the Arduino IDE, load up the ReceiveDump.ino sketch, and run it.
 Hopefully it will compile and upload.
 If it doesn't, you've done something wrong. Check your work and look carefully at the error messages.
 
 If you get this far, I will assume you have successfully added your new protocol
 
 At last, delete this giant instructional comment.
 
 If you want us to include your work in the library so others may benefit
 from your hard work, you have to extend the examples
 IRremoteInfo, SmallReceiver, simple Receiver, SendDemo and UnitTest too
 as well as the Readme.md
 It is not an act, but required for completeness.
 
 Thanks
 The maintainer
