Our Life With The Due

Just a little blog post dealing with our recent Arduino Due experiences..

Hope you enjoy it. And if there is any expert that can tell me why GPIO pin 53 is always high?

And if there is any expert that can tell me why GPIO pin 53 is always high?

Note that after reset, all of the pull-ups are enabled (from the datasheet).
Then, in variant.cpp, it's initialized as CAN pin (CANTX1) which is an output.
CANTX0 (labeled CANTX on the Due) is also always high.

They work as regular GPIO after configuring with pinMode().

Hhmm.. I thought I did use the pinMode().. Will check again, when I get round to it..
