* SendRawDemo.cpp - demonstrates sending IR codes with sendRaw
|
|
*
|
|
* This example shows how to send a RAW signal using the IRremote library.
|
|
* The example signal is actually a 32 bit NEC signal.
|
|
* Remote Control button: LGTV Power On/Off.
|
|
* Hex Value: 0x20DF10EF, 32 bits
|
|
*
|
|
* If it is a supported protocol, it is more efficient to use the protocol send function
|
|
* (here sendNEC) to send the signal.
