    • INTRODUTION TO EMBEDDED SYSTEM N ROBOTICS
    • LCD Display
    • 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.
    • 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 .
    • Application of Embedded system
    • MECHANICAL MODULESOFTWARE MODULE ROBOT ELECTRICAL MODULE ELECTRONICS MODULE
    • 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
    • MICROCONTROLLER ??? …• microcontroller (also microcontroller unit, MCU or µC) is a small computer on a single integrate circuit consisting of a relatively simple CPU .
    • 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.
    • 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
    • Types of microcontrollers(arch.)1) 80512) AVR3) PIC4) PSoC5) 68HC 116) eZ8,eZ807) Etc…
    • 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.
    • AVR classification:-AVRATMEGA ATMEGA 8 , ATMEGA16,ATMEGA32, ATMEGA 128
    • Atmega 8
    • Atmega 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•
