[quote:4275ad2dd6]However what happens with the LED at Portb.5?[/quote:4275ad2dd6]
I do not know, if you are receiving a correctly encoded RC-5 bit stream in the first place!
How are you monitoring the received RC-5 bit stream?
Do you own a scope? If so, then do you get transitions out of the decoder? Do you have the correct pre-amble(start bits). Does the scope trace match what you are supposed to be transmitting?
Does RC-5 work without the background feature?
What is transmitting the RC-5 bit stream? Is it correct? Is it the correct modulation rate?
Need to do some debugging to determine what's going on.
