Error in Nano board pin definitions in Wiring 1.0

[cver65]

Just found some lackind PIN definitions for Arduino :

Nano has 8 Analog Ins (from 0-7), while standard Uno etc using DIP only have 6.

Result is that A6 and A7 are "undefined" in Wiring while they should be defined (apparently as 6 and 7) in the "c:\Program Files\Wiring\hardware\Arduino\DuemilanoveUno\BoardDefs.h"

I also saw #define TOTAL_ANALOG_PINS       6

That is also incorrect.

Actually, this is strange as I expected to be able to use DigitalRead (A4) correctly, but that won't be the case here either.

To be discussed/solved. Probably the NANO needs to be handled separately after all.

Thanks Christopher, could you submit it to github issues? https://github.com/WiringProject/Wiring/issues?sort=created&direction=desc&state=open

Interesting.  I never looked at the Nano.  I guess that's my fault.  I just assumed it was a repackaging of the first boards into a "DIP" package.

Please add the issue!  We'll get 'er fixed.

Done. I also commented/supported the idea of aligning with Arduino and Maple by numbering the analog pins starting at the pin number (A0=55 for Mega etc.), like everybody else does. This allows things such as "digitalRead(A0)" to make sense without hassle.

hi Christoph, thanks, yes, that sounds very reasonable, "numbering the analog pins starting at the pin number (A0=55 for Mega etc.), like everybody else does. This allows things such as "digitalRead(A0)" to make sense without hassle"
