Below is not my sourcecode, just a reference for my project. My problem is how to add in library.
When i using AVR-GCC compiler, there is an error of no such directory/library.e.g. #include <Mega32.h>
How can i add in the #include <Mega32.h> library?
Or may be i should cut it to short, i have the compiling problem.
Anyone help me please. Thanks!
/*
This code contains all of our three state machines to run
the graphing calculator using a TV and two keypads.
This program is optimized for MEGA32 with 16MHz crystal.
Keypad one uses PORTA and keypad two uses PORTB
The TV uses PORTC. For debugging purposes, we have set up
PORTD to hyperterminal.

Its too long, i cut it.
If you all want to see more, i can post again. |
