RotaryEncoder library

RotaryEncoder library for Arduino Uno etc...

I checked the operation with EC12PLRGBSDVBF-D-25K-24-24C-61

Example program is here

Tutorial

1. Copy library files to your project

• RotaryEncoder.h
• RotaryEncoder.cpp

2. Include library

#include "RotaryEncoder.h"

3. Set up

1. define interruptable pin numbers

#define PIN_A 2
#define PIN_B 3

2. define and initialize RotaryEncoder object

RotaryEncoder encoder = RotaryEncoder(PIN_A, PIN_B);

4. Get encoded value

int val = encoder.getRotationValue();

Other

• Set max value and min value

encoder.setMaxValue(255);
encoder.setMinValue(0);

• Set increase and decrease value

encoder.skipValue = 4;

If set this, the value will increase to 0, 4, 8, ... and decrease to 0, -4, -8, ...

• Value rotation

encoder.isRotateValue = true;

If the max value is 10 and the min value is 0, the value will increase to ...,9,10,0,1,... and decrease to ...,1,0,10,9,...
