I just wanted to echo what someone said higher up - the default sending example, using delay(100), does not work with my Sony receiver. Changing it to delay(50) works perfectly. Lower than delay(50) seems to cause issues.

Hello Ken, i am trying to work with your library in one Arduino MEGA 2560. The sendRaw function is not working. I tested all PWM ports, from 2 to 13 on board, and i could not see the IR Led blinking with my camera. Any ideas ? Thanks a lot!!!!

I plan on using multiple infrared sensors. How would the library support that?

Hi,
sorry for my bad english.
I want create a bluetooth remote infrared with Arduino and Android.
I find a java parser for lirc conf file and I want test it.
It is possible create a most generic send function on arduino for codes parsed by Android?
I have all info and data from lirc file and i think it is possible compute a raw send data with Android and send it to arduino via bluetooth. The arduino decode it to IR Led.

2011-10-10T04:34:54.796-07:00

I am setting up an Arduino Uno to control remote control lights. IRRecord seems perfect to get the data I need. I modified IRRecord to output codelen and to output rawCodes after the irsend.sendRaw command.

Serial output:
Received unknown code, saving as raw

This does not activate the lights. However, if I cut/paste the codes into an array as per Luckylarry's example, it works.

Any idea why IRRecord does not?

Thanks for the library. I am using IRHashdecode for another application with no problems.

2011-08-09T20:21:15.646-07:00

Thanks for the library Ken. Question: will your examples work with an UNO? I think I have everything right and the codes I recorded match a work lirc configuration but I just don't seem to be able to get the stereo device to recognize the output. Any help is greatly appreciated.

2011-06-26T19:23:06.786-07:00

Ken, this library is awesome, thanks a bunch. Anyway, I was playing around with sending multiple codes with a single button press. I have one button to turn on the TV and the AV receiver, another button that selects the audio mode on the receiver, etc. This library is so powerful that with macros you can build a serious universal remote rivaling some of the commercial ones available.

I was just stringing commands together with a delay of (40) between each transmission and it seems to work ok. Just wondering if you have a different way of creating macros or if you could recommend optimum delay values, etc.

According to my camera phone, the IR LED stays on after the code has been sent - making for short battery life.

Has anyone else noticed this? Anyone have a fix?

It's using RAW, I don't know if that means anything in relation to the problem.

Thanks

2011-05-19T06:40:59.266-07:00

I'm trying to run this with a 56KBaud signal (TSOP1156 Receiver) but getting nowhere. As I'm new to Arduino can somebody tell me if I need to change anything anywhere please?

I have no idea of the signal format as it's not a domestic equipment remote that I'm trying to 'grab' and emulate - all I know is that the original equipment uses a TSOP1156 and (according to the info sheet) "The address is encoded into the IR sequence with 5 hamming code bits
and then manchester encoded to give a 32 bit complete code. Since manchester encoded then every transmitter sends 16 high and 16 low pulses. Giving an equal power on the beam. any erroroneous data is ignored by a recevier."
Tham eans absolutely nothing to me bot hopefully it may do to somebody...
Any assistance would be very welcome.

2011-04-11T08:38:37.415-07:00

After a bit of searching and experimenting I stumbled upon this side: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1176970454.

So the solution to the tune() imcompatibility is simply this code:
void freqout(int freq, int t)
{
int hperiod; //calculate 1/2 period in us
long cycles, i;
hperiod = (500000 / freq) - 7; // subtract 7 us to make up for digitalWrite overhead - determined empirically
// calculate cycles
cycles = ((long)freq * (long)t) / 1000; // calculate cycles

/* Serial.print(freq);
Serial.print((char)9); // ascii 9 is tab - you have to coerce it to a char to work
Serial.print(hperiod);
Serial.print((char)9);
Serial.println(cycles); */

for (i=0; i<= cycles; i++){ // play note for t ms
digitalWrite(outpin, HIGH);
delayMicroseconds(hperiod);
digitalWrite(outpin, LOW);
delayMicroseconds(hperiod - 1); // - 1 to make up for fractional microsecond in digitaWrite overhead
}
}

It works like charm with IRremote...

2011-03-30T01:58:30.560-07:00

Thanks for the great library! Unfortunately IRremote has
side effects on the build-in tone() library. Either sounds are
crippled or - after playing a tone - the receive library stops
working and returns 0 for any IR event.

Is there a way to fix this problem?
Or a workaround?

I found the error! Yes!! The answer is in this comment: "Hi reconnnn: I'm in the process of writing an explanation of LIRC data, but for your case LG usually uses 32-bit NEC protocol. Take the pre_data bytes in the LIRC file and join them to the bytes for the button you want to control to make a 4-byte hex number, and use sendNEC. Power on is probably 0x20df10ef; some LG devices use 0x897641be or 0x34347887. If you have an IR detector, you can read out what your remote sends, rather than looking in the LIRC files.

2011-02-09T11:06:03.112-08:00

I have no success with this. Trying to use it with a Creative DDTS-100. I've used values from http://lirc.sourceforge.net/remotes/creative/DDTS-100 and changed IrremoteInt.h like this:
// pulse parameters in usec

#define NEC_HDR_MARK 8973

#define NEC_HDR_SPACE 4760

#define NEC_BIT_MARK 591

#define NEC_ONE_SPACE 1675

#define NEC_ZERO_SPACE 567

#define NEC_RPT_SPACE 2308

I then use IRsendDemo and change the send command:

irsend.sendNEC(0x15EA, 16);

The DDTS doesn't react. I see the IR-beam in my digital camera and have placed the transmitter Led really close to the DDTS.
