When I build my project I get this which I have no idea waht is wrong and how to fix it

I can’t open those files here, please post them inline with <> tags.

3

Multiple definition of a vector usually means two (or more) libraries are trying to use the same interrupt resource, often a timer interrupt. But since I will not download code that is the best that I can say.

4

Sorry is this better.
<EPASController.h (1.5 KB)>
<EPASController.ino (15.2 KB)>

5

The choice of “…” or <…>
Depends on where those files are located.

The #include documentation will help you a bit. HERE

Not really. Read the forum guidelines to see how to properly post code and information on how to get the most from this forum.

Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.

Since one of the two definitions is in wiring.c and the only ISR in wiring.c is the Timer0 Overflow interrupt I think "EPASController" is trying to use the Timer0 Overflow interrupt.
