Encoder example

The encoder sensor device has to be connected to the sensor module. Encoder sensor device has a two 3,5 mm plugs what has to be connected to the sensor module 3,5 mm input jackets. The controller and sensor modules must be connected. Do not use this example to configure the IoT module.

The jackets must be inserted to the right input. Four channel input to D jacket (right) and three channel input to the A jacket(left).

Needed libraries

lib_deps = ITTIoT@1.0.5, ClickEncoder

The example code will print out encoder current position value

#include <Arduino.h>
#include <ittiot.h>
#include <Ticker.h>
 
#include <ClickEncoder.h>
 
#define ENC_PINA 12
#define ENC_PINB 13
#define ENC_BTN   0
#define ENC_STEPS_PER_NOTCH 4
 
ClickEncoder encoder = ClickEncoder(ENC_PINA, ENC_PINB, ENC_BTN, ENC_STEPS_PER_NOTCH);
 
Ticker encTicker;
 
bool encFlag;
uint16_t button;

  iot.printConfig(); // print json config to serial //Peale Serial.begin ja enne iot.setup
  iot.setup();
 
  encoder.setButtonHeldEnabled(true);
  encoder.setDoubleClickEnabled(true);
 
 
  encTicker.attach(1, setEncFlag);
}

  }
 
  if (lastService + 1000 < micros())
  {
    lastService = micros();
    encoder.service();
  }
 
  static int16_t last, value;
  value += encoder.getValue();
  // Send encoder reading to server

  {
