Hello
I need help with this EEPROM. i need to store the value from ir receiver so when the arduino power off and on it will remember the last ir code.
The project is "universal IR decoder and Encoder" with one push button. i'm not soo good with programming. I need yours help please...THANKS!!!
The sketch:
MODERATOR EDIT - Auto formatted code and added code tags
#include <IRremote.h>
int RECV_PIN = 11;
int BUTTON_PIN = 12;
int STATUS_PIN = 13;
IRrecv irrecv(RECV_PIN);
IRsend irsend;
decode_results results;

{
Serial.begin(9600);
irrecv.enableIRIn(); // Start the receiver
pinMode(BUTTON_PIN, INPUT);
pinMode(STATUS_PIN, OUTPUT);
}
// Storage for the recorded code
int codeType = -1; // The type of code
unsigned long codeValue; // The code value if not raw
unsigned int rawCodes[RAWBUF]; // The durations if raw
int codeLen; // The length of the code
int toggle = 0; // The RC5/6 toggle state
// Stores the code for later playback
// Most of this code is just logging
void storeCode(decode_results *results)
{
codeType = results->decode_type;
int count = results->rawlen;
if (codeType == UNKNOWN)
{
Serial.println("Received unknown code, saving as raw");
codeLen = results->rawlen - 1;
// To store raw codes:
// Drop first value (gap)
// Convert from ticks to microseconds
// Tweak marks shorter, and spaces longer to cancel out IR receiver distortion
for (int i = 1; i <= codeLen; i++)

if (i % 2)

// Mark
rawCodes[i - 1] = results->rawbuf[i] * USECPERTICK - MARK_EXCESS;
