README for AdaEncoder

Note that you MUST connect the two pins for your rotary encoder to 2 pins on the same PORT

on the ATmega chip. If you do not, your sketch will simply reset. I should probably remove

this restriction one day.

ALWAYS make sure you are using the latest version of the ooPinChangeInt library. Check this

page for the latest version and status:

These are the PORTs on the ATmega328:

 * Arduino Pins     PORT

 * ------------     ----

 * Digital 0-7      D

 * Digital 8-13     B

 * Analog  0-5      C   (== digital pins 14-19)

ATMEGA2560 Pin Change Interrupts, pins and PORTs:

     A14     PK6  22        0     PE0   8 - this one is a little odd.*

     A15     PK7  23

* Note: Arduino Pin 0 is PE0 (PCINT8), which is RX0. Also, it is the only other

pin on another port on PCI1. Therefore, this pin is not supported by this library.
