I'll start with the high digital outs and work my way down. :)<div><br><br><div class="gmail_quote">On Sun, Aug 7, 2011 at 1:54 PM, Andrew O'Malley <span dir="ltr"><<a href="mailto:aomalley@gmail.com">aomalley@gmail.com</a>></span> wrote:<br>

(I forget which) while uploading new code. It has to do w/ loading on<br>
the serial port. Slightly annoying for sure, so yes, if you can get<br>
away with not using D0 and D1, that's the easiest way to work around<br>
it.<br>
