Decode/Encode IR-Signals from LG Air Condition Remote ( AKB73315611 )
##Why? Wanted the automate my LG AC a bit, using a RPI and IR-Emitter/-Receivers and LIRC - unfortunately there was no template for the remote present - so i tried to reverse engineer it a bit :)
##Contents encoded_values.txt is a file with the encoded binary signals raw folder contains all the readings from the IR receiver bundled per mode-fan operation scripts folder contains all php files I used to decypher the IR-signals and the write it back
###encoded_values.txt contains the encoded values (raw->binary) for ON/OFF, SWING ON/OFF, AC LOW,MED,HIGH,CHAOS 18-30, AI L,M,H,C 18-30, HEAT L,M,H,C 16-30, DEHUM L,M,H,C - if you find something missing, tell me - but that's basically all the functions I use - feel free to contribute
###scripts/config.php a few "static" vars and settings - might need a bit of tuning depending on your IR - easiest way to do it, open mode2 -d /dev/lirc0 -m and write down the values - you should get a list like 400-500, 1450-1550 and two single values like 4000 and 8000 - define what's the average for every value, define a offset and you are fine :)
###scripts/analyze.php Use: php analyze.php FILENAME Feed it a Raw-File created by using mode2 -d /dev/lirc0 -m - examples are in the RAW folder - also multiple button presses are treated accordingly - just use a meaningful sequence ;)
###scripts/decode.php Use: php decode.php INPUTFILE OUTPUTFILE uses an INPUTFILE with a list similar to encoded_values which has to has the format KEY_NAME;BINARY and creates a config OUTPUTFILE with these keys in it
