Thanks Hans for making this thing clear - I'll try to find an adequate solution
for the rewritten pduino-help asap!

That confusion originates from the Arduino numbering scheme itself, since it
uses A0 for analog pins in analog mode, but then it uses a number when using
the same pin for digital things.
I think one way to represent this might be to allow the use of A0-A7 pin names
in addition to the numbers, but then the confusing thing would be that the
analog messages would then be [analog 14 0.2352(. So that's why I thought to
try to use only the numbers, no A0-A7, and try to make that as understandable
as possible.

yo bonitos
due to the pduino rewrite I've to reanimate this threat ;)
I would like to remove the ambiguity and confusion about this old and new way
of enabling the analog pins.
old way of enabling the analog 0 pin is sending the following to the arduino
object:
[analogIns 0 1(
enabling the same pin(analog 0) the new school way:
[pinMode 14 analog(
is this correct? if so what's a bit byte confusing for people is that in the
new way pin 14 equals the analog 0 pin - guess this is a peculiarity of
firmata? isn't there a possability to use f.e. A0-A5 for adressing the analog
pins?
thanks for info& salutis

Which one???
Not the one that is distributed together with [arduino] and [arduino-test] at
http://at.or.at/hans/pd/objects.html,
right?
yo it's in Pduino-0.5beta8 linked on this page
in the last subpatch [pd SWITCHING-INPUTS] you'll find the apropriate
messages.
There I find the same analogIns messages that are supposed to be the old ones
(but are the only ones I've found that
work for analog pins with the latest version of Firmata)
jep i agree they're the same - i think it's a matter of wrong denotation so due
to my knowledge there's nothing like old
and newer messages -> the current 'contemporary' message for enabling the
analog inputs is:
[analogIns pinumber 1=on; 0=off(
f.e. to enable analog pin 1:
[analogIns 1 1(
correct me if i'm wrong!
i don't know why this is commented with (optional)
I must have another version of the help patch, as I don't see such a comment
right behind the [pd SWITCHING-INPUTS] is a comment "<- example of switching inputs
on and off (optional)"
How are the messages you're talking about?
i guess it's a firmata peculiarity that you've explicit have to enable
the analog pins as in arduino they are enabled by default - but correct
me if i'm wrong.
Yes, I guess what you have to explicitly enable is to have the firmware _send_
the values to the computer. It would be
undesirable to have a constant flood of values of all pins whether you use them
or not.
jep right so with firmata the analogIns have to be enabled explicitly to use
them. i think the (optional) comment
somehow makes it ambiguous. as told i'll try to consider this in the
improvements we're working on!
