* TinySender.cpp
|
|
*
|
|
* Example for sending FAST or NEC protocol using TinyIR.
|
|
*
|
|
* NEC protocol codes are sent in standard format with 8bit address and 8 bit command as in SimpleSender example.
|
|
* Saves 780 bytes program memory and 26 bytes RAM compared to SimpleSender, which does the same, but uses the IRRemote library (and is therefore much more flexible).
|
|
*
|
|
* The FAST protocol is a proprietary modified JVC protocol without address, with parity and with a shorter header.
|
|
* FAST Protocol characteristics:
|
|
* - Bit timing is like NEC or JVC
|
|
* - The header is shorter, 3156 vs. 12500
|
|
* - No address and 16 bit data, interpreted as 8 bit command and 8 bit inverted command,
|
|
* leading to a fixed protocol length of (6 + (16 * 3) + 1) * 526 = 55 * 526 = 28930 microseconds or 29 ms.
|
|
* - Repeats are sent as complete frames but in a 50 ms period / with a 21 ms distance.
