Click to expand...

In your lcdportd header file, there is a function on line 5 that is declared as an implicit int. I assume this is your main file, you would need to either move the function above main and declare it before main.

The other warning is the same thing. But these don't crash the compiler.

Your putch and delay operations is what stops it. You either didn't create the functions or your header is missing them or you didn't import the right header to define them.

why dont you declare and define your own function. do not use the functions from library.
