  1. Block Diagram AVR Controller Bluetooth Tx/Rx M Driver Circuit PWM Bluetooth Tx/Rx

  2. AVR • Atmel AVR 8-Bit Processors come in a variety of configurations and packages • They all share a common core – registers, instructions, basic I/O capabilities • Our focus is the ATMega16

  3. ATMega16 Specs • 131 Instructions • 32 8-bit GP registers • Throughput up to 16 MIPS • 16K programmable flash (instructions) • 512Bytes EEPROM • 1K internal SRAM • Timers, serial and parallel I/O, ADC

  4. AVR CPU • PC: address of next instruction • IR: prefetched instruction • ID: current instruction • GPR: R0-R31 • ALU: Note internal data path

  5. Flash Memory • Programs reside in word addressable flash storage • Word addresses range from 0000-1FFF (PC is 13 bits) • Byte addresses range 0000-3FFF (0x4000=16K) • Harvard Architecture • It is possible to use this storage area for constant data as well as instructions, violating the true spirit of this architecture • Instructions are 16 or 32-bits • Most are 16-bits and are executed in a single clock cycle

  6. Applications • • High-tech Multi-user Toys • • Wireless Game Controllers • • Telemetry • • Wireless Audio/Video • • Electronic Point of Sales • • Wireless Control

  7. Blue-tooth Wireless Speed Control • Submitted By : • NISHA

  8. Low-IF 2.4-GHz ISM Transceiver • Features • • Fully Integrated Low IF Receiver • • Fully Integrated GFSK Modulator for 72, 144, 288, 576 and 1152 Kbits/s • • High Sensitivity of Typically –93 dBm Due to Integrated LNA • • High Output Power of Typically +4 dBm • • Multi-channel Operation • – 95 Channels • – Support Frequency Hopping (ETSI) and Digital Modulation (FCC) • • Supply-voltage Range 2.9V to 3.6V (Unregulated) • • Auxiliary Voltage Regulator on Chip (3.2V to 4.6V)

  9. What Is BLUETOOTH First of all, in case some of you don't know, Bluetooth is the common name for the new short range wireless technology that is able to transmit voice and data while working with mobile phones, music players, personal digital assistants (PDA) and computers.

  10. Bluetooth Name Okay, now for some history. The Bluetooth technology was given its name in reference to the Danish king Harald "Bluetooth" Blaatand. He was the one who unified Denmark and Norway between 940 and 985 AD. The reason Bluetooth is named after him is because it is known to unite the telecom and computing industries today. Makes sense, right?! It's all about unity!

  11. Advantages • Wireless • Bluetooth is actually inexpensive • Bluetooth is automatic • Standardized protocol • Low interference

  12. Adventages(continued….) •  Low energy consumption • Sharing voice and data • Instant PAN (Personal Area Network)

  13. Adventages(continued….) • Wirless There is no need of wires in wirless communication and bluetooth is a wire tecnology • Bluetooth is actualy inexpensive The technology of Bluetooth is cheap for companies to implement,

  14. Adventages(continued….) • Bluetooth is automatic Bluetooth doesn't have you set up a connection or push any buttons they will automatically begin tocommunicate without you having to do anything • .Standardized protocol Bluetooth is standardized wireless, meaning that high level of compatibility among devices is guaranteed

  15. Adventages(continued….) • Low interference Bluetooth devices almost always avoid interferencefrom other wireless devices.  Bluetooth uses atechnique known as frequency hopping, and alsolow power wireless signals. • Low energy consumption Bluetooth technology requires very little energy and willuse less battery or electrical power. This is an excellent benefit for mobile devices,

  16. Adventages(continued….) • Sharing voice and data The standard for Bluetooth will allow compatibledevices to share data and voice communications. Bluetooth simplifies driving and talking on your cell phone. • Instant PAN (Personal Area Network)You can connect up to seven Bluetooth devices toeach other within a range of up to 30 feet, forminga piconet or PAN.
