I'm playing around with recording and transmitting Infra Red signals from my tv remote. I'm using Arduino Mega. I found one program that records a received IR signal, and outputs the received array in the serial monitor. I then copy this array and paste it into a different program that transmits the IR signal. Both work, and are shown below.
IR receiver code:
// IR Receiver code. (WORKING ON MEGA)
//When you press a button on your remote control the code records it and prints the signal into the serial monitor, you copy this and paste it to be used in the transmitter code
#include <IRLibRecvPCI.h>
IRrecvPCI myReceiver(2); //IR Receiver on pin 2
void setup() {
Serial.begin(9600);
myReceiver.enableIRIn();
Serial.println("Ready to receive IR signals");
Serial.println("Point the remote controller to the IR receiver and press!");
}
void loop() {
if (myReceiver.getResults()) {
Serial.println("\n\n-------------------------");
Serial.println("Received IR signal:");
Serial.print(F("\n#define RAW_DATA_LEN "));
Serial.println(recvGlobal.recvLength, DEC);
Serial.print(F("uint16_t rawData[RAW_DATA_LEN]={\n"));
for (bufIndex_t i = 1; i < recvGlobal.recvLength; i++) {
Serial.print(recvGlobal.recvBuffer[i], DEC);
Serial.print(F(", "));
if ((i % 8) == 0) {
Serial.print(F("\n"));
}
}
Serial.println(F("1000};"));
Serial.println("-------------------------");
myReceiver.enableIRIn();
}
}
//------FOR EXAMPLE, I PUSHED THE "POWER ON" BUTTON ON MY TV REMOTE, IT OUTPUTS THIS (below) IN THE SERIAL MONITOR, COPY AND PASTE THIS INTO THE TRANSMITTER CODE-----------------

IRsendRaw mySender;

digitalWrite(9,LOW);

What I want to do is join the 2 codes together. So I can record and store an IR signal (multiple in the future) and then transmit it later on. I attempted some code (below), it stores the received signal on a temporary array, and then attempts to transmit it but it doesn't turn my tv on or off. I don't know where it goes wrong, or if it is possible, or if i should try a different approach. My thoughts are commented in the code below.
IR Transceiver code:
//IR Transceiver code, (NOT WORKING - Not sure if signal is being transmitted)
// Trying to add both reciever and transmitter code into one piece of code.
// I added 2 push button to allow for receiver mode, and transmitter mode.
// Note, the signal/array length (RAW_DATA_LEN) is differnt for each remote manufacturer you are using (from 20 to 68 in my case)
// My plan is to record the IR signal, and place it in a Temp Array of length 100 (to act as a "catch all")
// I will then be able to determine the length of the signal, and store that value at the end of the array, Temp Array [99]
// When i want to transmit the signal, I will create a New Array with length TempArray[99]
// Then i will transmit this signal
#include <IRLibRecvPCI.h>
IRrecvPCI myReceiver(2); //IR Receiver on pin 2
#include <IRLibSendBase.h>
#include <IRLib_HashRaw.h>
IRsendRaw mySender;
#define tempArrayLength 100 //100 in length
uint16_t tempArray[tempArrayLength]={0}; // Starts will all zero's
int NewArrayLength; // New Array varies in length
int ButtonRec = 8; // When pushed it will be in Receiver mode
int ButtonTrans = A3; // When pushed it will transmit the signal in the New Array (made using data from the tempArray)
int ListenFlag=1; // not sure if i need this, it just stops the serial monitor from repeating ("Listening....")
void setup() {
pinMode(9,OUTPUT);
pinMode(ButtonRec,INPUT); // pulled UP, LOW when pushed
pinMode(ButtonTrans,INPUT);// pulled UP, LOW when pushed
digitalWrite(9,LOW);
Serial.begin(9600);
Serial.println("\n\n Record a signal first..., nothing in temp array to transmit \n Hold down rec button while sending the signal");
}
void loop() {
if(digitalRead(ButtonRec)==LOW){
if(ListenFlag==1){Serial.println("Listetning... "); ListenFlag=0;myReceiver.enableIRIn();} //enables IR Receiver
if (myReceiver.getResults()) { //a signal has been stored in the buffer array
for (int i = 1; i < tempArrayLength; i++) {
tempArray[i]=recvGlobal.recvBuffer[i], DEC; //start copying the buffer array into the temp array
if(tempArray[i] >0){ //If i'th value is still above zero then carry on the for loop
}
else { //If i'th value is zero, then we have reached the end of the recorded signal
tempArray[i]=1000; // note all signals must end with a value of 1000, this is for the "sender" program to know??
NewArrayLength=i; // we now know the length of the signal
tempArray[99]=NewArrayLength;//store "length of signal" value in the 99th/last cell of the tempArray
