I found this: http://forum.arduino.cc/index.php?topic=49649.0
I do not claim to understand it, but he says that what I am doing is super slow. Maybe that is what is gumming up the works. I will try his suggestion (blindly) and see what happens. I note that the post is almost 6 years old, so maybe it no longer applies, but I can give it a try. I had assumed that my code used the buffer on the card, but he says that print does not. -Denis _______________________________________________ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
