Question/Request: Pioneer IR decode from previous project #4

Closed irakhlin closed 4 years ago

irakhlin commented 4 years ago

Hello, I apologize in advanced about opening an issue under your repo not directly related to the source. I came across a older forum post of yours: https://www.eevblog.com/forum/projects/48-bit-(6-byte)-ir-remote-protocol-and-checksum/ in which you linked to https://github.com/kpishere/GetRawIRData. I am currently working on essentially the same thing and was hoping you may have migrated this into another repo. Please feel free to obviously close this issue.

Thank you very much,

Hmm. I think you found were it ended up irakhlin. I've split it apart a little bit in a way to make it more generic. As of right now, you see two different IR protocols supported, an HAVAC heatpump one and a quite common NEC one.

Hi,

Thank you for responding! For lack of a better place I will leave this here, I have decoded the majority of the message for my mini split (Pioneer mini split). Its composed of two "messages" each 6 bytes each. The second message is easy, its an exact binary invert of the first (flip each one for 0, 0 for 1). From the first message I seem to have worked out the mode, temperature, commands, ect and it seems the checksum is the last 8 bit section but I cant seem to apply the same algorithm you used ( sum of the inverses of each byte minus 1 all inverted).

I've attached a big list ive been referencing the sequences if you have some time to take a look. full_binary_list.txt
