Quadrature encoder with optimized interrupt routines. Encoder will directly define interrupts to minimize overhead. N.B. there is a conflict if any other code in your patch or any libraries you use require attachInterrupt().

P1port
Port for signal one. Use a hardware interrupt pin for best performance.
P2port
Port for signal 2. Use a hardware interrupt pin for best performance.
Readpulse
A pulse to this input triggers a read of position.
Donepulse
Pulse on read.
Posnumber
Position.
