[I'm cross-posting this from https://www.microchip.com/forums... -- pardon me if this is considered inappropriate practice, but I think this forum is more likely to produce a useful answer!]

 

I've looked over the documentation for the SAM E70 Xplained Ultra User's Guide and, while it mentions the generic EXT connector, it doesn't document EXT1 and EXT2.
 
I need to know exactly which processor pins / functions are connected to each of the EXT1 and EXT2 pins.  I could reverse engineer it by tracing through the schematic, but I'm surprised that it's not documented like all the other Xplained boards.  For example, see Table 5-1 in the SAM E54 Xplained Pro User's Guide.
 
Even stranger, I have this vague recollection of seeing such a table somewhere, but I certainly can't find it now.  Any pointers?

In the schematic on page 32, no tracing needed. But I agree it's strange it is not included in the usual table format.

Agreed:

 

"I could reverse engineer it by tracing through the schematic..."

 

... but the tricky part is finding all the other places that a given external pin connects to.  For example, it's not obvious at first that both EXT1 and EXT2 share SPI0.  And then the question becomes which SS does each one use, and are those signals used anywhere else?  And since the wires have aliased names, can you be certain that you found all their uses?

 

Honestly, I'm just grumpy about having presbyopia: either I have to squint at tiny text, or blow the PDF up so large that navigating is a pain.  A table would be nice...

Would also be nice if manufacturers (not just  Atmel  Microchip) would provide this information in an easily machine-readable form - so we don't have to keep manually transcribing it from what are, essentially, still just "printed" documents.

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
