• Don't make everything inline! It is a lot easier to maintain, expand, etc. if all the code that actually interacts with stuff is buried, because you only need to change it once.
• The compiler is extremely weird. If you get syntax errors for no apparent reasons (after checking for things like parens, semi-colons, etc.), type the line again, including the line breaks on each side.
• If you really can't figure it out, sleep on it. Meaning: Leave it be and come back tomarrow.
• [edit]Use #define for I/O port references. Same as reason the first: If you change which port it's on, you don't have to go through all your code.[/edit]
