Reference missing mention of constants A0, A1, ...

[NeatNit]

As I mentioned along with some other stuff on the forum, the analog input pin constants are not mentioned in the Arduino reference - not under Constants and not in analogRead.

But actually, I'm unclear on how they are used. I have an Uno and the constant A0 has the value 14. The example AnalogReadSerial uses this constant to read the value: int sensorValue = analogRead(A0);
However, the analogRead reference page says:

pin: the number of the analog input pin to read from (0 to 5 on most boards, 0 to 7 on the Mini and Nano, 0 to 15 on the Mega)

So which is it? Is the reference page plain wrong, or are A0 and 0 equivalent for analogRead?

analogRead supports two argument values: The analog channel number (0-something), or the pin number (e.g. 14+ on a Uno) that can also be passed to digitalWrite. Does that clarify?

Yes, thank you... though pert has already clarified this on the forum.

not in analogRead.

This issue was fixed by #463

This issue remains.
