Jawen,

Plan out what you would like to do, in this case driving an LED display.
1. Read the data sheets on the LED display to learn how to drive it.
2. Write down in words a step by step process of how you would accomplish the driving of the LED display.
3. Then translate each of those steps into either 'C' or assembly language instructions.

Hint: driving a LED display requires some kind of lookup table which will contain hexadecimal values that correspond to the numbers/characters that you need to display.

If you make an attempt at this and post the code, I am sure that the Forum will be most helpful if you run into problems.

Good Luck

Jacob
