Arjit intro

  1. 1. INTRODUTION TO EMBEDDED SYSTEM N ROBOTICS
  2. 2. LCD Display
  3. 3. EMBEDDED System???....1)An embedded system is a special-purpose computer systemdesigned to perform one or a fewdedicated functions.2) Physically, embedded systems rangefrom portable devices such as digitalwatches and MP4 player to largestationary installations like traffic lights,factory controllers, or the systemscontrolling nuclear power plants.
  4. 4. Embedded system:- An intro. An embedded system is a computer systemdesigned for specific control functions within alarger system .• Embedded systems contain processing coresthat are typically Microcontrollers .
  5. 5. Application of Embedded system
  6. 6. MECHANICAL MODULESOFTWARE MODULE ROBOT ELECTRICAL MODULE ELECTRONICS MODULE
  7. 7. Microprocessor1) A microprocessor incorporates the functions of acomputers central processing unit (CPU) on asingle integrated circuit.2) It is a multipurpose, programmable device thataccepts digital data as input, processes it accordingto instructions stored in its memory, and providesresults as output
  8. 8. MICROCONTROLLER ??? …• microcontroller (also microcontroller unit, MCU or µC) is a small computer on a single integrate circuit consisting of a relatively simple CPU .
  9. 9. Microprocessor v/s MicrocontrollerMicroprocessor: Microcontroller:• Memory is not there. • It has owes Memory.• Microprocessor only • Microcontroller canprocess the i/o data. also process the data.• Microprocessor has more • A Microcontroller isgeneralized functions. more specific to its task.• Brain of any computing • Microcontroller ismachine. complete Computing machine.
  10. 10. Simple difference betweenMicroprocessor and Microcontroller1) Microprocessor = CPU2) Microcontroller = CPU + Peripherals + Memory3) Peripherals = Ports + Clock + Timers + UART +ADC +DAC+ other stuff4) Memory = EEPROM + SRAM + EPROM + Flash
  11. 11. Types of microcontrollers(arch.)1) 80512) AVR3) PIC4) PSoC5) 68HC 116) eZ8,eZ807) Etc…
  12. 12. Atmel AVRThe AVR is a Modified Harvard architecture 8-bitRISC single chip microcontroller (µC) which wasdeveloped by Atmel in 1996. The AVR was one ofthe first microcontroller families to use on-chipflash memory for program storage, as opposed toOne-Time Programmable ROM, EPROM, or EEPROMused by other microcontrollers at the time.
  13. 13. AVR classification:-AVRATMEGA ATMEGA 8 , ATMEGA16,ATMEGA32, ATMEGA 128
  14. 14. Atmega 8
  15. 15. Atmega 16
  16. 16. • Pin configuration of Atmega 8•••• • VCC• • GND•• • Port A (PA7..PA0)•• • Port B (PB7..PB0)•• • Port C (PC7..PC0)•• • Port D (PD7..PD0)•• • RESET•• • XTAL1•• • XTAL2•• • AVCC• • AREF•
