Hey Kevin, cool down. I am trying to help here.
You may know little, much or everything, I don't argue about that.
I am pointing out some cases that I susspect or have opposed during my experiments and would like someone have pointed me when I was awake all night to spot them...
Anyway, seeing a matrix, one guesses that scanning is needed. I did not quite understood from the beggining that finally only one element should stay on at a time.
The programm in C was writen to scan the matrix. For a completely different application than yours.
For your case, yes, if you want to just light one element at the time, only the col and row that corresponds to must be ON. There is no need for scanning resulting the flickering you see.
So the programm should only set the corresponding bits at proper level (0 or 1) and wait for a few seconds. At C I don't know how though.
