After referring to this thread from last June:
[Link: remotecentral.com]I have a couple of questions about panasonic ir codes that I hope someone can help me with.
The power toggle switch from my tv remote looks like this:
0000 0071 0000 0032 0080 003f 0010 0010 0010 0030 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 002f 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 002f 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0030 0010 0010 0010 002f 0010 0030 0010 002f 0010 0030 0010 0010 0010 0010 0010 002f 0010 0010 0010 002f 0010 002f 0010 0030 0010 002f 0010 0010 0010 002f 0010 0aaf
After reading the above thread, and Prontoedit Learned IR Code Display document, I understand that the first 0000 means the code is learned, the 0071 is the frequency (in this case approx. 37 khz), then the 0000 means that there are no codes in the burst pair sequence #1, and the 0032 means that there are 50 pairs in the burst pair sequence #2. Then the 0080 003f is the lead in burst pair, and the final 0010 0aaf is the lead out burst pair in the sequence.
Looking at the ir codes for discrete on and off in the files section for a panasonic television, the middle data section contains pairs of 0010 0010 and 0010 0030, which represent binary 0 and binary 1 respectively. Decoding the binary 6 bytes then from the posted discrete ON would yield 2,32,128,0,62,190 and the discrete OFF would yield 2,32,128,0,63,191. To this point, I think I understand what's going on.
Looking at the hex code from my power button, though, is confusing me. In addition to the 0010 0010 and the 0010 0030 pairs is 0010 002f. I know that 0030 and 002f are very close in decimal value (48 vs 47). If I assume that 002f is interchangeable for 0030 in the code representing the binary 1, it would decode to 2,32,128,0,61,189. But I don't know if that's a correct assumption to make. If it's not interchangeable, then I'm very confused how there can be 3 different pairs in a binary system.
The discrete on and off codes don't work for my panasonic tv, so I'm trying to determine what the difference between my power toggle and the discrete codes is to see if the discrete codes can be tweaked to make them work on my tv. Can anyone shed some light on this for me?
Thanks,
Mark
