Multiplexing query? Answered
Hi, I am having a problem with multiplexing. I have my grid set up with 60 leds all connected in rows and columns as per usual and my eventual goal is to have each led come on one after another. Sorry I can't think of a single term to describe this action at the moment. This is for a clock, in particular the seconds but the way I see it, when row 1 (my cathodes) is high ie to ground and after each column (my anodes) is lit sequentially (found my single term) when I get to the next row of LED's, it seems that as columns 1-8 are already high, when row 2 goes high then all the LED's in that row will light simultaneously.
If I could have some pointers, that would be great.
Additional information: My set of LED's will be run off a PIC 28X2 with DS1307 RTC in case anyone needs to know.
