Sziasztok,
Egy Samsung TV távirányítót szeretnék helyettesíteni arduinóval. Innen letöltöttem az IRLib könyvtárat, és az IRrecord példát szeretném kipróbálni.
A TV távirányító jelét veszi is, de nem világos, hogy az adó LED -et hova kell kötni. Kell módosítani a kódot?Ez a példaprogram:
/* Example program for from IRLib – an Arduino library for infrared encoding and decoding
* Version 1.5 June 2014
* Copyright 2014 by Chris Young http://cyborg5.com
* Based on original example sketch for IRremote library
* Version 0.11 September, 2009
* Copyright 2009 Ken Shirriff
* http://www.righto.com/
*/
/*
* IRrecord: record and play back IR signals
* An IR detector/demodulator must be connected to the input RECV_PIN.
* An IR LED must be connected to the appropriate pin.(See IRLibTimer.h) for your
* machine's timers and erupts.
* Record a value by pointing your remote at the device then send any character
* from the serial monitor to send the recorded value.
* Also demonstrates how to use toggle bits which must be controlled outside
* the library routines.
* The logic is:
* If an IR code is received, record it.
* If a serial character is received, send the IR code.
*/
#include <IRLib.h>
int RECV_PIN = 11;
IRrecv My_Receiver(RECV_PIN);
IRdecode My_Decoder;
IRsend My_Sender;
/*
* Because this version of the library separated the receiver from the decoder,
* technically you would not need to "store" the code outside the decoder object
* for this overly simple example. All of the details would remain in the object.
* However we are going to go ahead and store them just to show you how.
