Objectives:

This lab will require you to: 

• Learn to use Keil Environment
• Build a project in Keil
• Write a simple C program
• Compile (build) a Keil project
• Use the the debugger to run and debug a program

Getting Started

There are some on-line tutorials that are a pretty good introduction to using the Keil environment.  Find the CD folder in the Keil folder and run the SETUP.EXE program.  This will give you a menu - you want the "Tutorials and Training" option.  The three tutorials, "Creating Projects", "Testing and Debugging" and "Advanced Simulation" are all worthwhile (just ignore the market-speak).

There are also Keil manuals in the lab, the on-line Help from within Keil, and the following links:

• The Keil "Getting Started" guide (won't be much help yet)
• Primer for the Keil 8051 C compiler (this is a lot better)

Here is about the simplest program you can imagine.  Start a project, type in this program (or cut and paste) and then use the debugger to step through the program, watching the registers and the output port P0.  When you make your project, use the SMALL code size and SMALL data size.

#include <reg51.h>

void main() {
  char i;

  while (1) {     
    for (i = 0; i < 100; i++) {
      P0 = i;
    }
  }
}

Once we get to running this program on the microcontroller, we are going to connect the port P0 to one of the 7-segment displays.  Write a program that turns on one segment at a time, rotating the segment in a circle using the outside 6 segments.  For now don't worry that the segments will rotate too fast - we'll fix that later.

What to Turnin

Turn in your C program that rotates the 7-segment display LEDs.
Demonstrate that your program works using the Keil debugger and have us sign off on the C programs.
