Is there something I should check? I did notice that if I modify the COL.4 = 0 to something like COL.2 = 0 ... I got some "rounded" display which might be the form of the smiley face circle. For example if the display has the following look where [b]X was off[/b] and O was on: XXOOOOO[b]XXX[/b]OOOOXX XXOO[b]XX[/b]OOOO[b]XX[/b]OOXX XXO[b]X[/b]OOOOOOOO[b]X[/b]OXX XXOOOOOOOOOOOOXX XXOOOOOOOOOOOOXX XXOOOOOOOOOOOOXX XXOOOOOOOOOOOOXX XXOOOOOOOOOOOOXX XXOOOOOOOOOOOOXX XXOOOOOOOOOOOOXX XXOOOOOOOOOOOOXX XXOOOOOOOOOOOOXX XXOOOOOOOOOOOOXX XXOOOOOOOOOOOOXX XXOOOOOOOOOOOOXX XXOOOOOOOOOOOOXX [b]Otherwise[/b] [b][/b] when col.4 = 0 I get all LEDs on like this: OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOO ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=176818#m178882 Need assistance?
