After adding:
% 4 ==0
and val/4
I have counting by 1. But it doesnt works properly for left knob. SS and 8 - they are PCINT. For right knob work ... good but not ideal for all steps - MISO and 13 pin, only MISO is PCINT.
Problem with left knob:
- start from 0 position/count, turn right of leftKnob- I got nothing. Then turn right of rightKnob - i got -1 (this move for check if leftKnob has still 0 count):
11:08:36.687 -> Reset both knobs to zero
11:08:36.687 -> Left = 0, Right = 0
11:08:53.421 -> Left = 0, Right = -1
11:08:53.888 -> Left = 0, Right = 0
then turn left leftKnob:
then I got new print in serial monitor of "0" for leftKnob:
11:09:48.631 -> Left = 0, Right = 0
again turn left:
11:10:28.146 -> Left = 1, Right = 0 , its ok
then turn right, should go to 0, but it stuck at 1, nothing change in serial monitor, but after turning rightKnob ... I got "0" for leftknob and -1 for rightknob
11:11:04.374 -> Left = 0, Right = -1
maybe problem is with leftKnob because it uses both pins as PCINT? Maybe it would be good to turn off PCINT for second pin of leftKnob?
