nid help on LED blinking

Now that is a real beaut.

I just hope it was from a very bright student who wanted to be a bit cheeky with his teacher.

I once saw some source code where the person didn't realize that decimal and hexadecimal is just different presentations of the same number, and that the C compiler supports hexadecimal constants.

So the code contained:

#define HEX_00 0
...
#define HEX_A0 160
#define HEX_A1 161
...
#define HEX_FF 255

Good to have in case he needed a hexadecimal number and forgot how to translate to decimal :)

Or maybe he had seen one of the binary declarations that exists here and there, and not realized that a header file with:

...
BIN_0110_1001 0x69
BIN_0110_1010 0x6a
...

exists just because binary numbers aren't part of the standard language, while the compiler has very good hexadecimal support directly in the language standard.
