Hoping someone can help me understand my IR receiver code.
I'm using the example library called IRRemote->SimpleReceiver, and modified it slightly so that I can understand it better.
code here:
/*

* Demonstrates receiving NEC IR codes with IRrecv

I've added my own line in to try and see how to get the bit of code that I want.
unsigned char DECODEDDATA;
......
......
IrReceiver.printIRResultShort(&Serial);
Serial.println(IrReceiver.decodedIRData.decodedRawData,HEX);
DECODEDDATA=IrReceiver.decodedIRData.decodedRawData,HEX;
Serial.println("vvv");
Serial.println(DECODEDDATA);
Serial.println("^^^");
When I use my remote, I receive results in the Serial Monitor as follows:
Protocol=SONY Address=0x1C5A Command=0x39 Repeat gap=12100us Raw-Data=0xE2D39 20 bits LSB first
E2D39
vvv
57
^^^
I really want to return this value in my DECODEDDATA variable:
0xE2D39
Even this value would be OK:
E2D39
But what i get is this:
57
What do I need to do to get either 0xE2D39 or E2D39 into the variable DECODEDDATA?
