I am playing working with an IR detector and as may remote controls as I can find. I am having some trouble with a couple and was wondering if anyone has any help.
First, AT&T U-verse TV/Cable controller. I can press the same button several times and I seem to get a different data streams each time. And it is not just a "toggle" bit.
Second, ReQuest multimedia controller. I found this one at a pawn shop. What I like about it is that it has 64 button with all 26 letters, 10 digits, and the usual buttons you would find on a TV/VCR/DVD/DVR controller. This one seems to have a time unit of about 800us. Does not use a "Manchester" or "Pulse Distance" encoding. It appears that the data is directly encoded with the presence or absence of the carrier. I think I have found an 8 bit ASCII byte in the middle of the data but there are more fields with unknown data.
