I suppose you could do a fancy program that does a Checksum of the memory and will serially flash LEDs on all ports to confirm. But then I would have to figure out how to connect 40 LEDs at one time. [I know I could do it in 8 LED banks]. This just fine. Above all keep it simple. We have begineers amongst us. One resistor and one LED is enough. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=85377#m86048 Need assistance?
