Perhaps I just haven't RTFMd enough yet.

 

Is there a unique ID in each of the chips? I've found where you can tell what kind of chip it is. I'm thinking of the xMega where it has 11 bytes uniquely identifying each chip by lot number, wafer number, x and y position on the wafer...

The SAM4S Series datasheet happens to be in my Adobe Reader's recently used list:

Quote:

8.1.3.7 Unique Identifier
Each device integrates its own 128-bit unique identifier. These bits are factory-configured and cannot be changed
by the user. The ERASE pin has no effect on the unique identifier.

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
