  2. A Small Idea ...

  3. Project • Our objective is to make a portable device that will transparently control devices that are attached or running on the personal computer.

  4. The Idea • Use radio transceiver to communicate between PC and handheld PC • The handheld PC will be able to manage certain external devices and internal software on the PC

  5. Application • CD Player • Identification Card • Device Controller

  6. CD Player • Be able to play the CD Player on the PC from the handheld PC

  7. Identification Card • Be able to: • store information on the card • retrieve and update information on the card from the handheld PC • download the information from the handheld PC to the database on the PC

  8. Device Controller • Simulate applications that can be connected to the serial or parallel ports on the PC • Test the simulation by connecting a LED to the different ports and controlling the LED by the handheld PC

  9. Equipment • NEC MobilePro 800 • GB Series Radio Transceiver • Cyberflex Smart Card • Reflex 20 Smart Card Reader • Cables (serial, parallel) • Software (C++, Java)

  10. NEC MobilePro 800 • Handheld PC running Win CE • 131MHz NEC VR4121 MIPS • 24MB ROM/32MB RAM • USB/Serial/VGA out • Type II PC Card Slot • Touch Screen with Stylus Pen • 9.6”W x 7.5”D x 1.0”H

  11. GB Series Radio Transceiver • Frequency : 138-172 MHz, 406-470 MHz (Multiple Bands) • Computer Interface : RS 232 • Baud Rate : 1200 - 9,600 Baud • Protocol : CSMA • Optional : Forward Error Correction (Hamming Code)

  12. Cyberflex Smart Card • Looks like a credit card • Contains microprocessor for processing capability and memory for storing instructions and data • Program in Java

  13. Reflex 20 (Smart Card Reader) • Supports ISO 7816 Smart Cards • Bit sampling and error correction • PCMIA Type II Interface • Supported Data Speed: 38.4K bps • Win CE supported • 10cm x 5.5 cm x 0.4 cm

  14. Cost NEC MobilePro 800 $999 2 Radio Transceiver NA Reflex 20 $99 Smart Card NA Level Converter NA Total $1098+

  15. Software Work (80%) • PC Software • Device Controller for port communication (Serial, Parallel) • Scanner • Smart Card Program • Application to store Smart Card Data in handheld PC, send the data to PC database and store it in the PC database

  16. CD • Revision of CD Player source code • Handheld PC’s application to control PC’s CD Player

  17. Hardware (20%) • Connection of all equipment • Build a simulated application that connects a LED to the different ports

  18. Team Member Responsibilities • Chris • Connection of LED to different ports • Make applications that light up the LED • Radio Frequency Communication (sending and receiving data) • Application on the handheld PC that sends appropriate data

  19. Vanessa • Device Controller for the PC that reads data from the serial port and sends that data to the right application • Radio Frequency Communication - application that sends and reads the right data through the radio

  20. Kaori • Revision of CD Player Code • Programming Smart Card • Application that interprets the information sent by the reader • Application on the PC that interprets data from the handheld PC
