Descripton: It is a library for rotary encoder.Of this library purpose is detect direction of encoder rotation and increase or decrease encoder rotation count. it requiers PCINT ISR for work correctly.
WARNING:
-
if you don't use PCINT ISR it doesn't reads fast rotations, especialy WITHOUT PCINT ISR it doesn't works at all if you have a big code.
-
Also pins and ports only can be changed in 'encoder.c' file by changeing values of macros.
