Mam problem z enkoderem tzn nie umiem odpalić go w przerwaniach a jedynie cyklicznie w pętli. Płytka na której to chodzi to mega_256 i to też tak jakoś dziwnie bo pracuje poprawnie jak kręcę wolno to działa licząc w lewo jak i w prawo ale najdziwniejsza sprawa że jak nie używam to w jakiś dziwny sposób zlicza w lewo (nikt niekręci pokrętłem a sam liczy). 

Enkoder podłączony jest jak na linku.

Nie jestem pewien czy Piny 2,3 można używać do przerwania (Interrupt) ale wedle strony https://www.circuitstoday.com/arduino-me...schematics

[color=var(--h-color, #161616)]Hardware Interrupt Pins :[/color]

Digital pin 18 – 21,2,3 hardware interrupt is used for interrupt services. Hardware interrupt must be enabled with global interrupt enable to get interrupt from other devices.

Kod:

//YWROBOT
//Compatible with the Arduino IDE 1.0
//Library version:1.1
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
