Hi everyone!
I am programming lcd+rotary with center switch. I am tring to write values at a specific place on lcd screen. For ''setting1'', it prints at the right cases: (7,1). For ''setting2'', it prints on (7,0) instead of (7,4). It seems like the case (7,4) don't want values on it
Sea the code line 157 to 171
Also I would like a suggestion to show the values on the lcd in real time while turning the rotary to select value.
