- 2. • Relax, don't try to take any notes, ...just write your questions... • Slides • Twitter – http://twitter.com/migaber • Email – migabora@gmail.com • Feel free to email me, download these slides, and share your thoughts with me.
- 3. • Session objectives • Computing systems overview • Embedded Systems!! .. What does it mean ?? • Microprocessors and Microcontrollers • Micro-controllers and it's applications • How to start your Graduation ‘embedded project’
- 5. Computing systems overview
- 9. Embedded systems.., what does it mean ?!
- 10. • In Arabic ( ). • A control system designed using a micro- computer to perform a specific tasks. • Consists of Mechanical parts in addition to electrical.
- 16. Microprocessors and Microcontrollers
- 17. • In 1971 Intel 4004 microprocessor released • and Intel 8008 in 1973 http://en.wikipedia.org/wiki/Microprocessor
- 19. • In 1977 Intel made the Myth … Intel 8048 • MCS-48 family • They combined RAM and ROM on the same chip
- 20. • PROM - Programmable ROM • EPROM - Erasable PROM • EEPROM - Electrical EPROM • Flash memory
- 21. • 8-bit ALU, Accumulator and 8-bit Registers • 8-bit data bus – It can access 8 bits of data in one operation • 16-bit address bus – It can access 216 memory locations – 64 KB (65536 locations) each of RAM and ROM • On-chip RAM – 128 bytes (data memory) • On-chip ROM – 4 kByte (program memory) • Four byte bi-directional input/output port • UART (serial port) • Two 16-bit Counter/timers • Two-level interrupt priority • Power saving mode (on some derivatives) http://en.wikipedia.org/wiki/Intel_MCS-51
- 22. • Small instruction set to learn • Built in oscillator with selectable speeds • Easy entry level, in circuit programming plus in circuit debugging units • Inexpensive microcontrollers • Wide range of interfaces including I²C, SPI, USB, USART, A/D, programmable comparators, PWM, LIN, CAN, PSP, and Ethernet http://en.wikipedia.org/wiki/PIC_microcontroller
- 24. • USB controller support • LCD controller support • Low-voltage devices operating down to 1.8 V • Watchdog timer (WDT) • 8-bit and 16-bit timers • Analog comparator • 10 or 12-bit A/D converters, with multiplex of up to 16 channels • 12-bit D/A converters http://en.wikipedia.org/wiki/Atmel_AVR
- 25. • Microprocessor • Microcontroller – CPU is stand-alone, – CPU, RAM, ROM, I/O and RAM, ROM, I/O, timer timer are all on a single are separated chip – designer can decide on – fix amount of on-chip the amount of ROM, ROM, RAM, I/O ports RAM and I/O ports. – single-purpose – general-purpose – Ex. 8051, PIC mc, Atmel, – Ex. 8085,8086 mp, Phillips Motorola 6800, Intel’s 8086
- 26. What do you think ?? Robotics automation security remote-sensing audio-mixers and moooooooooooooooooooooooreeeeeeee
- 27. • You need little hardware knowledge with your software. • Select the family and chip according to your application. • Learn how to program your device using its datasheet • Start to use its IDE and development tools and join the embedded world .
- 28. • PIC has its IDE (called MPLAP) used to write your code and debug it and to generate your .HEX file • Download it from here http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=81 • Use the .Hex file to simulate your project, Proteus 7 is the best for this case • Every thing goes in the right way ?? Burn the code to your chip and enjoy your project, you will need a programmer in this step
