Topic: ATSAM3X8E Block Diagram and Pins (Read 473 times) previous topic - next topic


Hello everyone,

I am studying the block diagram and the pinout of the ATSAM3X8E of the Arduino Due board, but I am a bit confused. How do the pins match to the I/Os of the block diagram?


You can find all the information you need in the Greynomad pinaout diagram :

That's a pretty awful "block diagram"; the Arduino mostly treats pins as GPIO, which shows up in the block diagram as little blocks (PIOA, PIOB, PIOC) in the upper left-hand corner, not connected to anything.  Sigh.
