Hi,
Looking for someone can help me. I’ve recorded with lirc and decoded my Air Conditioner remote, but don’t know how proceed now.
I’m able to output a string of 1 and 0 matching the configuration I want (temp, mode, fan speed, etc). How can i convert this string into a IR signal?
As you know, every time a button is pressed to the remote, all configuration is sent to the main unit, so cannot write a configuration file for lirc (cannot write a raw signal for every combination of configuration variables into the config file, there must be something simple and quick to do).
Also, need to calc the checksum that is the sum of bytes mod 256 (found a matching output here https://www.scadacore.com/tools/programming-calculators/online-checksum-calculator/) in this mode:
reverse the bytes -> appy checksum -> reverse the checksum
Many thanks

Temp: value in celsius -> convert to binary -> reverse -> apply not (negation)
Pos: value from 1 to 5 -> convert to binary -> reverse (000 auto | 111 swing)
OnOff: 1 on 0 off
Fan: value from 1 to 3 -> convert to binary -> reverse (000 auto)
Mode: 110 cool | 010 deum | 111 fan only | 100 heat | 000 auto

then, checksum from the link above (the result Checksum8 mod 256 is 0C = 00001100 wich match the checksum of the decoded signal when reversed to 00110000)
