The data lines are from Po and control from P2.
So they are multiplexed. You will have a much better chance interfacing to the LED driver chip inputs. i REALYY dont know how to go about. Then why did you even start? to do anything you must 1) analyze problem if good result go, else say no 2) work out details, if good result go, else say no 3) make a concept design (<1 day), if good result go, else say no 4) accept job, start designing evidently you skipped 1), 2) and 3) Erik |
