I suspect you are missing a needed header .h file from your source code. E.g., you might have a function that returns a char but it is missing a prototype, so the compiler assumes it returns an int and grabs garbage bits from a register fo...
If you want to use a function across multiple source files, you should declare the function in one header file (.h) and then put the function definition in one source file (.c or .cpp). All code that uses the function should include just the .h file, and you should link the resulti...
