Analog pin as digital.

[Plazmin]

Arduino boards allow the use of analog pins as digital. Can the firmata use analog pins as digital? How to configure it?

Hi Plazmin,

Yes, it depends on the boards... but you can use the "digital number" of the pin.

For example, in an "UNO", A0 is digital 14. Then, you can use that pin using that digital numeration.

I'm not sure if the firmata works like that. I don't want to burn the port in arduino so i want 100% confirmation.
