[QUOTE="troky, post: 169276, member: 54237"] Timecode is array of pulses/spaces in 85.3us steps. Documentation says that the last element of timecode array is SPACE but from my experience (when timecode.lenght is odd) that is not true. First element is aways PULSE. Problem is that I use IgorUSB with 90s2323 uC that has max. timecode length limted to 36. That should be enough for RC5,6, SONY... but not for NEC protocol (AFAIK)... But NEC code can be extracted because we have LAST 36 timecodes. Since time resolution is 85.3us some time margins must be used. Currently, I have finished RC5 decoding only and trying to do SONY/NEC(partial). I would really like to see IR protocol detection routines because I am having problems with it. My detection algo is pretty primitive: if there are long pulses and long spaces in timecode then it is RC5, if there are only long pulses it is SONY and if only long spaces it is NEC :D Another issue is key repeating... but later about that ;) [/QUOTE]
