Main purpose:◦ To run programs on devises

“Mini Computer” – Contains memory space

Devise for embedded control

Use a computer to program

Can download programs from computer

Can output information to computer

Contains input/output ports

Everywhere!◦ Computers

◦ Remote controls

◦ Cell phones

◦ Cars (engine, antilock breaks, cruise control, etc.)

◦ Microwaves

◦ Dishwashers

◦ TVs

◦ DVD Players

◦ Almost every electronic with a user interface

Used For◦ Writing Programs

◦ Sending Programs to C8051

Programmed in C

Used For displaying text from:◦ Main Program

◦ Input

Be Careful with circuit◦ Circuit boards are very delecate

Only hold circuits by the edges◦ Do not touch anything metal

Before setting down:◦ Make sure rubber feet are in tact

◦ Make sure area is clean and dust-free

When storing:◦ Use anti-static bag and cushioned packaging

◦ Store at room temperature

To USB Debug Adapter

To Power Cord

LED should light up when powered

USB to Computer

To power outlet

LEDs should light up when in use

1. Open SiLabs IDE

2. Go to File New File

3. Type in C Program Copy Sample Program:

#include <stdio.h>

main ()

{

printf(“PDI Studio 5/n");

}

4. Compile program by pressing the Assemble/Compile button on the toolbar or press Project Assemble/Compile File

5. Build program by pressing the Build/Make button on the toolbar or press Project Build/Make Project

Assemble/Compile Button

Build/Make Button

Note: If your program does not work, it will notify you at steps 4 and 5 and you will have to debug before attempting to connect

6. Go to Options Connection options and choose USB Debug Adapter and then OK

7. Press the Connect button (or alt c)

LEDs on the Debug Adapter should now be on

Connect Button

8. Press the Download code button

Download Code Button

Go to Project Target Build Configuration

Enable automatic connect/download after build and then press build again

Go to C:\SiLabs\MCU\Examples\C8051F02x Click on the “Blinky” folder, and open the c

file in IDE Press on the green “go” button The green led on the board should start

blinking Press the red button for the program to stop Each program has a description of function

and reason for different lines Use these programs as guilds for your

programs

8 ports, 0 through 7

Each port is 1 byte (8 bits) wide

You can address to entire bytes or individual bits

Each port can be assigned as input or output

C8051 will read the ports as◦ 0 volts as false

◦ +3 volts as true

Setting by bit (one of eight bits of the port)◦ To assign b7 of port 0 :

sbit bit7 = P0^7;

bit7 = 1;

Set as Input◦ Port 3 pin 7

P3MDout &= ~0x80;

P3 | = 0x80; *****

Set as Output◦ Port 2 pin 2

P2MOUT |= 0x04

For individual bits, first read entire port, then use masking to determine value of bit

Describe Masking Here

Open Secure CRT

Change settings and connect (try different com numbers) **

Right click on Serial-COM3 and select “Session Options…”

Click on emulation, change the scrollbackbuffer to 32000, and press ok.

Make a new project and file in IDE (save as 384test.c

Copy this program:

#include "c8051.h"

int main(){

Sys_Init();printf("\n\n\ntesting...\n");printf("done for now...\n");while(1);

}

Compile and build the code

Connect and download code

Start the code

Text should display on Secure CRT window ***
