4. Tevatron Technologies Focus Area and Sector

5. DEPARTMENT OF EMBEDDED SYSTEM
• An Embedded system is a combination of computer hardware and software
which is designed to perform many operations such as to access the data,
process the data, store the data and also control the data in electronics based
systems. In embedded systems, software commonly known as firmware
Basically embedded systems are task specific devices
• Embedded system is defined as a way of working, organizing, performing
single or multiple tasks according to a set of rules
• Hence it covers all the industries like
- BIOTECHNOLOGY
-TELECOME
- MILTARY
- AUTOMOBIEL
- CONSUMER ELECTRONICS

6. APPLICATION

7. WHAT I DO.??
 Presentations on Latest Technologies
 Presentations on my Project
 Study lectures by our mentors.
 Programming and hardware interfacing of different modules with atmega8
microcontrollers.
 Idea discussion
 Putting on logic on the programming

8. ATMEL / AVRFAMILY
 AVR stands for ADVANCED VIRTUAL RISC or Alf and
regard RISC processor.
 The AVR is a modified Harvard architecture 8-bit RISC single-
chip microcontroller, which was developed by Atmel in 1996
 The AVR was one of the first microcontroller families to use on-
chip flash memory for program storage
 AVR’s are best known for ease-of-use,
– low power consumption, and high level of integration

9. HANDS ON EXPERIENCE WITH
MICROCONTROLLER
ATMEGA8:

10. FEATURES:-
• High-performance
• Low power consumption
• 130 Powerful Instructions – Most Single-clock Cycle Execution
• 32 x 8 General Purpose Working Registers
• 8K Bytes of In-System Self-Programmable Flash
• 512 Bytes EEPROM
• 1K Byte Internal SRAM
• Programming Lock for Software Security
• Three PWM Channels
• High code density
• Master/Slave SPI Serial Interface

11. Hardware Interfacing's and Coding:
 Masking is the key concept for programming ATmega controllers.
 LED interfacing with Microcontroller.
 Seven Segment Interfacing with Microcontroller
 LCD interfacing with Microcontroller
 USART/UART interfacing with Microcontroller

12. SOFTWARE’S USED:
AVR STUDIO 4.0
AVR studio is an Integrated Development Environment (IDE) by ATMEL for
developing applications based on 8-bit AVR microcontroller
PROTEUS 7 DESIGN SUITE
• this software helps programmers in hardware implementations.
• It provides a huge number of electronic components and REAL TIME
ANOMATONS of the hardware designs.
• This is the perfect tool for engineers to test their microcontrollerr designs
before constructing a physical prototype in real time
