Re: IR Toggles

IR codes typically have prefixes or suffixes which define the which device you are talking to. Using the code you already know, you can factor these parts out and search a much smaller space. For example, a Sony TV has only 7 bits (128 codes) to search.

According to the IR table commonly found on the internet (which I have now added to the site - see the link below), Kenwood codes 32 bits as follows:

GROUP * 10000h + (Code * 100h) + (Code XOR FFh)

To me this says there are 16 group bits, only 8 bits for the code and then an inverted version of the code. So you only have 256 possibilities to check.
