/*
|
|
* Sony is backwards from most protocols. It uses a variable length mark and a fixed length
|
|
* space rather than a fixed mark and a variable space. Our generic send will still work
|
|
* however we need a custom decoding routine because it's difficult to get the generic
|
|
* decoder to handle a variable length mark without cluttering up the code to much.
|
|
* According to the protocol you must send Sony commands at least three times so we
|
|
* automatically do it here. Sony can be 8, 12, 15, or 20 bits in length.
|
|
* The 8 bit version uses a shorter trailing space at the end. The signal is modulated
|
|
* at 40 kHz however most 38 kHz receivers are broad enough to receive it.
