Hi all I am having problems trying to divide the freq of a square wave. I want to feed in a 50/50 square wave a varying frequencies and get out of the other end a divided 50/50 square wave. Ideally I need to be able to hard wire the division /2 /4 or /8 to be decide after some tests. I had though I could do it with a 4017 but while I can set up the division OK I cannot make it 50/50 duty. Can any body point me in the right direction.
