Using interrupts for a rotary encoder

hi guys,

i have rotary encoder trying use work heading selector in auto-pilot panel simulator. need rotary encoder changes stored value supposed between 0 , 359. managed rotary encoder working, value jumps , down crazy every time try change it, value increases more turned (i turn 1 step , value increases 5) or after increasing 1 step value increases , comes (1, 0, 1, 0).

i recommended use interrupts have no idea is, how use it, , whether improve anything.

any help? please?

thanks

i don't think have seen rotary encoder solution did not require use of interrupts.
