I am really new to 8051 programming, but my first program gives this warning: UNRESOLVED EXTERNAL SYMBOL SYMBOL: ?C_START MODULE: STARTUP.obj (?C_STARTUP) what shuld i do?
but my first program gives this warning:
First, no, that's not a warning. It's an error message.
Second, you're using the wrong program as a first one. Your first program should be the one from the tutorial, built exactly like the tutorial tells you to. Odds are you'll find your mistake yourself, once you've complete the tutorial.
