 		 #133269 - Dont count bits until you have the sentinel!
Responding to: ???'s previous message
You're still counting bits before checking the sentinel! You won't necesarily have the first 5 bits being the sentinel - thats where your code fails.

Think carefully about the problem - you have a sequence of bits - there may be garbage bits before and after the data. So you have to look for a known bit sequence - the sentinel. Only then can you count off bits!
