The Technology

Based on the Microcontroller card you have built

Controlled by a C program in PC

- this is what you must write

You do NOT have to program the microcontroller

ASCII characters are used to transfer data between PC and microcontroller

System Configuration

RS232 to COM1

C Program on PCCircuit Board

What the Circuit Does

All communications is via RS232 (9600,N,8)When the button is pressed – circuit sends YWhen the button is released – circuit sends NBit pattern of received character controls LEDs

example: receives character @ which is 1000000

bit 6 LED turns ON, all others are off.

or: receives character A which is ASCII 1000001

bit 0 and 6 LEDs turn ON.

System Diagram

Push switch sends Y

Release sends N

Send character to display pattern

Example of Controlling LEDs

bit 6bit 5

bit 4bit 3bit 2

bit 1bit 0

Receives the ASCII character 4

This has bit pattern 0110100

So LEDs of bits 2, 4 and 5 are on

Character to Control Display

Flow of Program

Start: Wait until button pressed (receive Y)

count=0

While button pressed (not received N)

increment count

if (count=7) count=1

LED pattern=count

delay

Return to Start

T&N3311 PJ1


What you have to do

Use hyperterminal or to familiarize yourself with the way the circuit board works

Practice using serial communications with C

(see Help about Serial Communications)

Write pseudocode to describe the operation of the PC program

Write and debug your C program

Project 1 Task 1

T&N3311 PJ1


What you must submit

You should submit a short report on your program containing:

o The Pseudocode

o The C program (including comments)

o A description of the operation of the program

Report to be submitted in week 20

Your lecturer will want to see the program working in week 20

Project 1 Task 1

T&N3311 PJ1


For the Brighter Students

It is possible that some groups will finish the program before week 20.

Think how the program can be extended

orDesign another game (or application) for the

board.Credit will be given for extra work done.
