FOUNDERHomi Jehangir Bhabha was thevisionary who conceptualised theIndian Nuclear Programme and alongwith a handful of Scientists initiatedthe nuclear science research in India

in March, 1944. His own wordsWhen Nuclear Energy has beensuccessfully applied for power

production in, say a couple of decadesfrom now, India will not have to look

abroad for its experts but will find themready at hand .

The Atomic Energy

Establishment, Trombay (AEET)was formally dedicated to thenation by the then Prime MinisterPt. Jawaharlal Nehru on January20, 1957. Later, Prime MinisterIndira Gandhi renamed AEET asBhabha Atomic Research Center(BARC) on January 12, 1967 as afitting tribute to Dr. Homi Bhabha

who died in an air crash onJanuary 24, 1966.

User preferences are included.


21/37

VB 6.0 SAMPLE WINDOW


22/37

KEIL PROGRAMMING

Used as back-end. Select the respective micro-controller. Vision IDE simulates all on-chip

peripherals. completely simulates all on-chip

peripherals. write & test applications before target

hardware is available.


23/37

KEIL SAMPLE WINDOW


24/37

OrCAD

for electronic design automation.

create electronic prints.


25/37

FLASH MAGIC S/W


26/37

SERIAL COMMUNICATION

How different from parallel ? sending of data one bit at a time.

beneficial for long distancecommunications.

no extra hardware is needed.

A serial port in computers mostly. A single communication line. Baud rate / symbol rate.


27/37

RS232 STANDARD

Interface connecting between a DTE& aDCE.

Uses serial binary data exchange


28/37

RS232 CONNECTOR

9 Pin Connector ona DTE device (PCconnection).

Male & female end. DTE DCE CD,RD,TD pins.

RTS,CTS pins.

INTERFACING

1.ADC

1.MAX232

3. LCD

when different electronic devices are attached connection of peripheral devices to computers


30/37

With : ADC

P1.0 P1.7 connected to D0 D7 of ADC. P2.2 connected to WR (bar) of ADC. P2.3 connected to RD (bar) of ADC. P2.4 is connected to HBEN of ADC. Control word is used.


31/37

With : MAX232

is a level converter. a level difference between voltage values

of the PC and the micro-controller.

used to interface the PC with the micro-controller to overcome the leveldifferences.


32/37

With : LCD

P0.0 P0.7 connected to D0 D7 of the LCD. P2.0 connected to RS pin P2.1 connected to R/W pin P2.2 connected to EN pin Control word for interfacing.

CONCLUSION

Microcontroller based Data Logger System for theconversion of analog to digital data is created. Theproperties of the data are also made to change according tothe user. I have used KIEL program as back end & VB 6.0

as front end. The interfacing of the microcontroller is alsodone separately with MAX 197 IC, MAX 232 IC and LCD.The analog data is fed into c & using MAX 197, convertedto digital form & the output is obtained at the visual basic.

The interfacing is done merely by connecting the pins ofrespective devices to c IC.Hence, a micro-controller based data logger system issuccessfully created, which converts an analog data into adigital value.
