Re: OWFS on Raspberry Pi

Nevermind. It just started working well enough for me to see what is going on.

Thanks!

OWFS on Raspberry Pi

Even though this is not Raspberry Pi specific, Im posting here in the hopes someone knows the answer or knows a better place to ask the question. I am using a raspberry pi and One Wire File System (OWFS) to gather sensor data from primarily 1-wire sensors. I have an older Hobby Boards 6 channel hub ...

Re: LIRC GPIO driver for homebrew adapter

I have already dowloaded your files and they do not contain the detail I'd like to see. I'm not changing code for LIRC as mine works as it is. Math to create checksum? What is the formula? (detail) No description of the process, so I will assume you know what all 144 bits mean and you juts create th...

Re: LIRC GPIO driver for homebrew adapter

"hi,, you can attach pdf file by zip. make zip than upload. my code is 144 bit long. and now i can send it. and it works fine.. special thanks to MBA. now ahead..." I am still interested in more details. Have you reverse engineered all 144 bits? If so, can you send me the results? How do you create ...

Re: LIRC GPIO driver for homebrew adapter

I now have Raspberry Pi with LIRC able to send 4 commands to my hangar heat pump:
OFF
AUTO_ON
HEAT_ON
COOL_ON
These are 'captured' streams. I still have not fully reverse engineered the bit stream, in particular the checksum at the end.

Re: LIRC GPIO driver for homebrew adapter

It looks like the YMGI heat pump uses 66 bits in its commands.

Re: LIRC GPIO driver for homebrew adapter

Have not seen any post on controlling a heat pump with raspberry pi LIRC, nor received any responses to my email; but I will go ahead and post anyways. Today I took my Raspberry Pi Test IR setup out to the hangar, made sure the heat pump was off & sent the 1 command stream I had built which should h...

Re: LIRC GPIO driver for homebrew adapter

I cant attach whole file so.. download http://www.ostan.cz/IR_protocol_analyzer/ and load the attached sample.. In looking at your data & spreadsheets, it would appear that Mitsubishi & YMGI heat pumps use the same controllers/protocol; so I am very interested in your status & progress. Last summer...
