Hello
I’m going to make the same connection with the same Rotary Encoder.

I have already done a test with arduino UNO board where channel A connected is to pin 2 and channel B connected to pin 3, to use interrupts, everything works fine here is the setup for connection on UNO BOARD.

…..

void setup() {
pinMode(2, INPUT_PULLUP); // internal pullup input pin 2
pinMode(3, INPUT_PULLUP); // internal pullup input pin 3
//Setting up interrupt
//A rising pulse from encodenren activated ai0(). AttachInterrupt 0 is DigitalPin nr 2 on moust Arduino.
attachInterrupt(0, ai0, RISING);
//B rising pulse from encodenren activated ai1(). AttachInterrupt 1 is DigitalPin nr 3 on moust Arduino.
attachInterrupt(1, ai1, RISING);
}

…..

Now, with CONTROLLINO I want to make same function and I’m happy to read your post with your suggestions but I am little confused (is possible to have a picture of the connections?):

i am looking at your schetch:
…
unsigned long A = 3; // ( is this interrupt pin ? )
unsigned long B = 2;
…
pinMode (A, INPUT); // not INPUT_PULLUP since we are attaching external Pullup reistors
pinMode (B, INPUT); // not INPUT_PULLUP since we are attaching external Pullup reistors
St.

…

Are you using pin header or screw terminal?

I suppose screw terminal, beacuse you connect PULL-UP resistors to 12V ,but If you are using screw terminals, why don’t you initialize them as A3 or A2 in the schetch, and you define input as 3 an 2 as PIN HEADER?

<div>

And instead..

If you are using pin headers why do you use the PULL-UP resistor connected with 12 V and not with 5V ?

(It would be interesting to be able to insert images in these posts.)

Thank in advance for your help
