I am learning LFSR, for its application, can it be used as a counter?

e.g. If I want to count from 0000 to 1111, how to use LFSR? I have thought much on it. But I can't find a way to use it. Maybe it can only be applied on some specific counters instead of all kinds of counters. Am I right?
 

Hi

LFSRs are used in generating Psudeo Noise signal, so they have a large period and i think they can not be used in generation of sequentional patterns.

You can use LFSR as a counter if order of count sequence does not matter for you - when there is only one rule that every state should be in count sequence.

But if you need to go strictly in ascending/descending order through all states e.g. 000,001,010, ..., 110, 111, then LFSR is not a choice for you.
