WIRELESS MESSAGING VIA MOBILE/LANDLINE

Project Descreption

The main objective of this system is to transmit message or text through ordinary Land Line Telephone/mobile from one end (source) to another end (designation). This is get achieved by the DTMF technology. It has two sections one for editing the text and to transmit the edited text and the other section consist for receiving the text message. The system works on the DTMF technology. (Dual Tone Multiple Frequency).
It involves several steps. They are
DTMF decoding/Encoding process
Ring sensing
ON/OFF hook detection
Displaying the message in LCD
The above process is get achieved by the microcontroller AT89S8252/AT89C51/52.Thus Microcontroller controls the whole system.
As the title “wireless messaging via mobile/landline phone” itself indicates that this project deals with the transfer of message from one mobile to another or one landline to another without using wire connection.

The DTMF tones sensing circuit display the message at LCD as sent by other end by means of tone transmission.

Microcontrollers & Use in Embedded Technology

Its fun programming and working with microcontrollers. With microcontrollers you can create a piece of hardware which acts according to your wish (obviously with some limitations !). Examples are you can flash a LED, drive a 7 segment display, print text on a LCD, receive signals from a remote control, control electrical appliances of your room, build a robot that follows a line on the floor and avoids obstacles coming in between, frequency meter and infinitely many more..

BSNL JTO COACHING

Basically a Microcontroller is a mini computer with CPU, Memory, I/O lines etc. Microcontrollers are much better for smaller embedded systems than their ancestors i.e. microprocessors, if you are developing a system using microprocessor, then your hardware or circuit will be more complex whereas if you choose a microcontroller, your hardware becomes simple because all the necessary peripherals such as RAM, ROM, TIMERS, I/O ports etc are embedded in a microcontroller. Therefore it is also called a mini computer on a chip. Now we will start with interfacing various devices to microcontrollers (Assuming you have basic knowledge of 8051 architecture and assembly programming and also C). I have chosen 8051 microcontroller due to its simplicity in architecture and assembly language, and learning 8051 chip is much easier than other microcontrollers if you don’t have any prior knowledge on microcontrollers. For more detailed information of hardware architecture and assembly language of 8051 microcontroller you can refer hardware manual and instruction set from ATMEL’s homepage.

Most of the projects and tutorials published here are based on Atmel’s AT89S52 microcontroller, it is a 8- bit microcontroller with 8051 architecture, comes in a 40 pin DIP, contains all necessary peripherals required for a hobby project. Now for a microcontroller to be operational the minimum hardware you need is a crystal oscillator, power supply, power on reset etc. So I have come up with a very simple development board to carry on the projects and interfacing tutorials published here. (Note: This development board is not compulsory; you can also rig up the circuits in breadboard since most of the circuits are simple). You can construct the development board on a general purpose circuit board. (Soon I will be publishing PCB layout for this).

8051 Development Board.

We will start with interfacing microcontroller with LED’s, Displays, Motors, Relays etc.

· Interfacing LED(s)

· Interfacing 7 segment Display

· Interfacing multiple 7 segment displays

· Basics of PWM

· Interfacing Relays

· Interfacing 4×4 keyboard

· 8051 Serial port

· many more to come…

In order set up your simple home lab, you need

· keil or any other assembler/compiler.

· ISP programmer circuit

· ISP programmer software

· Target hardware (your development board or circuit).

8051 Development Board

I have designed a development board for practicing 8051 microcontrollers. The development board is simple one containing minimum hardware required for a 8051 chip to function. The 8051 chip used in this development board is 89S52. The AT89S52 comes in a 40 pin PDIP package. It consists 8kB in system programmable flash memory for code storage, 256 bytes of RAM, 32 I/O lines, three 16 bit timer/counters, one full duplex serial port and many more. For further details you can refer the datasheet.

Figure below shows the circuit diagram of the development board. Click on the image to enlarge. I have connected pull up resistors for all the ports in the circuit diagram, but pull ups are compulsory only for port 0. You can neglect pull ups connected for other ports since they are connected to pull ups internally.

This circuit can be easily constructed in a general purpose circuit board. One can neglect the seven segment display and 8 LEDs if they wish to build it separately. I will be publishing the PCB files for this board soon. Keep visiting.

Some Images of my 8051 development board built on breadboard. This is my first version of my board so the 7 segment display is not present.

Microcontroller 7 Segment Interfacing

Seven segment display is a basic type of display which can display numbers from 0 to 9. The circuit for interfacing single 7 segment display is shown below.

Driving a 7 segment display is as simple as flashing LEDs, but here we are flashing 7+1 LEDs. The 7 segment display module has 8 LEDs (7 segments to display number and one segment for decimal point or dot) arranged in a particular manner as shown in image below.

By driving (in the sense controlling ON and OFF conditions) these LEDs in various combinations, we can display the numbers 0 to 9. There are basically two types of 7 segment displays, they are common cathode and common anode. In common cathode, the cathodes of all the LED segments are connected together, we should apply a logic 1 or high input to a segment pin to light up that particular segment, and in common cathode the case is opposite. Table below shows the combinations of inputs to be applied to 7 segment display for digits 0 to 9.

For common cathode displays
Digit	binary input value	hexadecimal input value
0	11111100	FC
1	01100000	60
2	11011010	DA
3	11110010	F2
4	01100110	66
5	10110110	B6
6	10111110	BE
7	11100000	E0
8	11111110	FE
9	11110110	F6

For common anode displays
Digit	binary input value	hexadecimal input value
0	00000011	03
1	10011111	9F
2	00100101	25
3	00001101	0D
4	10011001	99
5	01001001	49
6	01000001	41
7	00011111	1F
8	00000001	01
9	00001001	09

The images shown below are the photographs of 7 segment add-on board for my microcontroller board, I have included one 7 segment in the current version of my development board, so if you are using that circuit then you don’t need an external 7 segment display board. Click on the image to enlarge.

The assembly language source code for interfacing 7 segment display is given below.
