3. An embedded system is a computer
system is designed to do one and
specific functions[1][2] often
with real-time computing
constraints .
1. INTRODUCTION OF EMBEDDED SYSTEM

4. It is embedded as
part of a complete
device often
including hardware
and mechanical
parts.

5. Embedded systems
control many
devices in common
use today

6. Traffic Control systems,
T.V, Washing Machine,
Computer etc.
2. USES OF EMBEDDED SYSTEM

7. 3. 8051 MICROCONTROLLER
A microcontroller is an economical
computer-on-a-chip for doing with
specific tasks, such as displaying or
receiving information through LED or
remote controlled devices.
 The 8051 is an 8-bit microcontroller
which means that most available
operations are limited to 8 bits

8. 4.Block Diagram of 8051 Microcontroller

9. 5. PIN DIAGRAM

10. 6.FEATURES OF 8051
i. RAM – 128 Bytes (Data memory)
ii. ROM – 4Kbytes (ROM signify the on – chip program space)
iii. 32 general purpose registers each of 8 bits
iv. Two 16 bit Timer/ Counter
v. Input/output Pins – 4 Ports of 8 bits each on a single chip.
vi. 3 internal and 2 external interrupts.
vii. 8 – bit ALU (Arithmetic Logic Unit)

11. 8. INTERRUPT
An interrupt is a communicated
to the controller, by a hardware
device or software, on receipt of
which controller momentarily
stops and responds to the
interrupt.

12. 9. SOFTWARE
Software, is a collection of
computer programs and related data
that provide the instructions for
telling a computer what to do and
how to do it.

13. 10. KEIL µVISION
The KEIL 8051
Development Tools are
designed to solve the
complex problems
facing embedded
software developers.

14. USE OF COMPILER AND PROGRAMMER
Compiler: KEIL
Programming Tool: ISP
1.Double Click on the icon present on the desktop.
2.The following window will be popped-up

15. 3. Go to the project & click on new project

16. 4.Make a folder on desktop & give file name.

17. 5.when you click on the save button ,following
window opens

18. 6. Select ATMEL & AT89S51 / Philips & 89c51RD2xx

19. 7. Then select NO on the pop-up given below.

20. 1.Then make a New File.

21. 9. Write or copy your code there & save it with extension .c
or .asm depending on your coding.
2)Go to target & then source group, right click on there &
click on the option add files to the project.
Select your asm or c file which you want to add.
3)Go to the option for target, click on output &tick on create
hex file option

22. 4)Now build target.(Click on the pointed option)...
5) It will show you 0 errors &0 warning on Output Window.

23. 12. HARDWARE OF
MICROCONTROLLERS
The onboard has P89C51RD2. Oscillator for
frequency generation DC supplies sockets 8 outputs
led.
CENTRAL PROCESSOR
