... but surley there is a whooping mistake (or have
i missed something), in his explanation of the Pioneer
IR code.
The problem i have is in the example the two 8 bit words
for the device code and function are reversed?
If you look at the hex code, after the lead in, you get
1 1 1 0 1 0 1 0 which according to his explination is
the complement device code NOT the device code. Or as
i suggested before have I missed something.
You're absolutely right, Barry made a mistake with this one. Basically, he got his ONEs and ZEROs swapped, so the device and function codes that he quotes later on are all complimented (ie, to correct them, subtract his numbers from 255).
Good catch.
If you're into learning about IR signals, there are a couple more articles here (including a copy of Barry's article)
