I believe im having issue with putting libraries together. I have 2 lines of code that works on there own but when I put them together i'm getting the error code that is attached.
Breakdown of code:
I have got one code that has an lcd screen with a rotary encoder that when moved it increases and decreases the counter int and Counter int (void1).
Also a code that moves a stepper motor clockwise and anti clockwise then does some basic switching (void2). Both of these work fine on there own but when I put them in the same library, using different void loops, this error message occurs.
I have done as much research into these errors as I can but still cant get it to work, any suggestions?
Also I have these weird characters come up on my lcd (image attached). I thought it may be a hardware issue but I have checked and double check but it still happens. any advice will be greatly appreciated!
