hello!
so here is my problem. i have a pushbutton (controlling power on/ off toggle circuit using ltc2951) with the following led arrangement:
from my understanding this is called "charlie plexing". this would be simple enough to drive with a micro controller, but i have no idea how to control it without one "simply" (i started working out a design but it was overly complex, so i thought there must be a better way).
essentially the led's need to be controlled by 1 pin that when it is high turns led 1 on (2 off), and when low turns led 2 on (1 off). this pin is the EN pin on the ltc2951.
any suggestions for how this might be done?
