Dear all,
Regarding my first post (https://www.analysir.com/joomla/IRforum ... ?f=5&t=513), I identified the values that match my buttons (horizontal swing, vertical swing, temperature, fan speed and mode) but now i've problem with the checksum of the second frame....
I don't find the correlation between my values and the checksum value.
I've make lots of capture (change mode, change swing, change temperature, change and change speed fan) and i observed that the checksum values that change are among the line 225 to 239 of my excel file.
But when I just change the temperature, checksum values are changing between line 427 and 435.
You can find in attachment an excel file with differents values of temperature ( line 235 to 241) and the checksum at line 427 to 435.
Thanks in advance for your help.
FYI : I tried to emulate section below but it did not work (http://www.analysir.com/blog/2014/12/27 ... d-protocol)
When I have finished my project I would do an article on my remote

Hi psylo24
Normally, we would use the checksum calculator in AnalysIR to figure out the checksum (The reverse engineering tool also helps), which helps in more than 90% of cases, and I would ask users to send me a saved session file from AnalysIR if they needed help.
Unfortunately, as you don't have a copy and cant send me a session file, it would take too much time to work thru it (That is the reason we make the tool available - to save time)
However, if you watch the videos we posted - you might get some hints. https://www.youtube.com/AnalysIR/videos
It is usually an XOR, SUM, CRC-8, CRC-16 or similar on a byte or nibble boundary.
The checksum usually is in the last byte/nibble of a signal (not always) and sometimes if there are 2 parts to the signals - you can have 2 checksums (identical or different).
TIP: The bit order may also be a factor)

Hm ok,...
Well I think I'll buy the software but I would like to know the difference between "Marker" and "MarkerSpace" version ?!!
It's not clear on the following link : https://www.analysir.com/blog/get-analysir.
Thanks.
