First: you've already asked this question, and gotten answers -- why are you asking again?

Second: are you really, seriously, asking someone on the group to do a bunch of work for free, then send you the answer? There is no one good design for this -- if there was, then it'd be in the data sheet for the control chip you're using, and you wouldn't have to ask here.
