/*
|
||
|
|
* NECx is a variation of NEC protocol. The only difference is in the timing of the
|
||
|
|
* header. There are two variations NECx1 and NECx2. They differ only in the way in
|
||
|
|
* which they handle repeat codes. If you hold a button using NECx1 it does not repeat
|
||
|
|
* the same sequence. Rather it sends a special sequence consisting of the usual header
|
||
|
|
* followed by a normal mark, a "1" bit, and then a long space with a 108ms extent. Note
|
||
|
|
* this so-called "ditto" repeat code is slightly different than the one for regular NEC.
|
||
|
|
* When IRLib receives one of these special repeat sequences, it returns the
|
||
|
|
* value REPEAT_CODE which is defined in IRLibProtocols.h as the value 0xffffffff. If you
|
||
|
|
* send REPEAT_CODE, the send routine will create a special sequence for you.
|
||
|
|
* Whether it is a normal code or a repeat code the entire frame has a 108ms extent.
|
||
|
|
* The IRP notation for these protocols are:
|
||
|
|
* NECx1: {38k,564}<1,-1|1,-3>(8,-8,D:8,S:8,F:8,~F:8,1,^108,(8,-8,D:1,1,^108m)*)
|
||
|
|
* NECx2: {38k,564}<1,-1|1,-3>(8,-8,D:8,S:8,F:8,~F:8,1,^108)+
