Actually I have to use 96 LEDs , i.e. thrice of the I/O lines(32) of yhe controller. And the challenge is that, I have to glow them turn by turn, not simultaneously. So, I am confused about how to do that in both hardware connections and software. Waiting for help…. Thanks. Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
