// If you define ENCODER_DO_NOT_USE_INTERRUPTS *before* including
|
|
// Encoder, the library will never use interrupts. This is mainly
|
|
// useful to reduce the size of the library when you are using it
|
|
// with pins that do not support interrupts. Without interrupts,
|
|
// your program must call the read() function rapidly, or risk
|
|
// missing changes in position.
|

#define ENCODER_DO_NOT_USE_INTERRUPTS

#include <Encoder.h>

|
|
|
// Beware of Serial.print() speed. Without interrupts, if you
|
|
// transmit too much data with Serial.print() it can slow your
|
|
// reading from Encoder. Arduino 1.0 has improved transmit code.
|
|
// Using the fastest baud rate also helps. Teensy has USB packet
|
|
// buffering. But all boards can experience problems if you print
|
|
// too much and fill up buffers.
|
|
|
|
// Change these two numbers to the pins connected to your encoder.
|
|
// With ENCODER_DO_NOT_USE_INTERRUPTS, no interrupts are ever
|
|
// used, even if the pin has interrupt capability

Encoder myEnc(5, 6);
