Arduino IR Remote library not working

[ahdavidson]

Yes. I understand.

1. The routine does not wait forever with a zero value for the parameter; I still get -1 returns. There is some discussion about this earlier in this thread, but I don't think the library has been updated.

2. In any case, I can't afford to wait for even 1 second. I have other timings in the loop that need to be checked at least every 50 milliseconds, if not less.

there is no other option in the library - there is no interrupt-based IR reading code in there and we have no plans to write an interrupt-based system nor do we have a tutorial on how to write that kind of code, or know of any code that can do what you're looking for

I don't think an interrupt driven reader is all that hard if you are using a receiver like one of the Vishay TSOP devices. Basically, it's just taking an interrupt, reading the time, determining if it's a mark or space (based on rising or falling edge) and saving it away. The main loop can know to retrieve the sequence if the current "space" is longer than some predetermined period.

Have a look at this. It works quite nicely and is pin-change interrupt based. No protocol decoding, just comparing raw data.

I think I found the problem for the adafruit mini remote control. It does not properly follow the NEC protocol.
It sends "0 191" instead of "0 255" for address and checksum followed by correctly coded command and checksum.
I attached my C source that runs on an arduino.
