map decoded signals

[nielsgisbertz]

How do I use the decoded signals in a case structere? I tried to use the stored integeres from the library but without succes.

Not quite sure what you are asking for, but I guess it is something like this:

void loop() {
    receiver->receive();

    if (receiver->isEmpty())
        return; // timeout

    Nec1Decoder decoder(*receiver);
    if (decoder) {
           if (decoder.getD() != 12 || decoder.getS() != 34) // check device & subdevice (optional)
               return;
           switch (decoder.getF()) {
                case 0:
                     zero();
                     break;
                case 1:
                     one();
                     break;
               // ....
               default:
                    unknown();
           }
    } else {
         // not a NEC
    }
}

No, I don't know how that line works. but normaly "!" is inverted.
Quit new to programming and somtimes I struggle to find the correct search terms to lookup the syntax and code structure.
Thanks already fro the help!

Ah, I see I've indeed forgotten some breaks
Will give that try. and let you know
edit:
The program prints the code it received, and doesn't loops each time trough the "default" and "else" structure.
I only don't get any output from the case structure.

FYI:
Goal is to use the LG remote from my TV to control some basics of my Marantz PM7000.
The source select is to give a pulse to my Raspberry Streamer/DAC to switch sources. This is not tested yet because I'm waiting for the extra board from Audiophonics.

A NEC decode is characterized by three (8-bit) parameters D, S and F. Normally, you require all three to match in order to trigger an action. The if (...) line checks that the D and the S parameters are 12 and 34 respectively. If they do not match, no further processing is made. This was intended as an example. It appears that you should change 12 to 4 and 34 to 251 (=255 - 4).

Hope this helps!

Now I get a output on the led.
But no reaction from the PM 7000

these are the values from the Multidecode example.
The 1/0 is the toggle for each sequential button press

// Command #1: MAIN VOLUME UP
// Protocol: rc5, Parameters: D=16U F=16U (output on the Serial Monitor: RC5 16 16 1/0)

// Command #2: MAIN VOLUME DOWN
// Protocol: rc5, Parameters: D=16U F=17U (output on the Serial Monitor: RC5 16 17 1/0)

// Command #4: MUTE
// Protocol: rc5, Parameters: D=16U F=13U (output on the Serial Monitor: RC5 16 13 1/0)

Led blinks: check bij Phone camera, visible red led in series and has reacted, by chance, once on a IRRemote program.

Seems that the original problem is solved.

But no reaction from the PM 7000

Sorry not enough information. Possibly the signal parameters are wrong?

I'll set up some experiments and come back to you.
Let's finish this, then document it and use it as example to help others to use your library.
