Design Tools

• Microchip PIC18F452/8 on PICDEM2 boards• MCP 2551 CAN transceivers• MCC18 compiler using MPLab IDE• Philips Bluetooth units• CAN2USB• Protocols Used:

– CAN, Bluetooth, HWC Protocol

Components

• End Point– Microchip PIC18F452 microcontroller

• 40MHz operating frequency• 32Kb Internal Memory• Philips Bluetooth unit attached via UART

– Frequencies• The Bluetooth unit’s maximum transfer rate is 750KB/sec• The maximum transfer rate between the PIC and the Bluetooth

unit is 115KB/sec

• Access Point– Microchip PIC18F458 microcontroller

• All of the above• CAN 2.0B peripheral interface

– Frequencies• The CAN connection maximum transfer rate is 1MB/sec

Components Cont.

• Controllers– HP Ipaq 3870

• External Bluetooth module– Connection via serial port

• Windows CE 3.xx

– PC• USB to CAN adapter• Web interface

Project modules

• Ipaq Module – Using Smart Remote Controller Project by

Pavel Vilk and Piotr Drubetskoy

• PC Module– Using Access Point simulator on

CAN2USB from HWC Project by Ehud Ravitz and Lee Blum

Smart Remote Controller Project by Pavel Vilk and Piotr Drubetskoy

• Implementation of a system which includes a single Remote Controller capable of controlling several devices in different rooms via Access Points, connected via LAN.

• The Remote Controller and the Access Point are implemented on a PDA with a Blue Tooth link and CE OS.

• The Access Point manages a piconet of devices implemented as black boxes on a PC.

HWC Project by Ehud Ravitz and Lee Blum

• Aim of the projectCreate a cheap wireless control network on household appliances.

– Create Bluetooth connection between an Access point and an End Point.

– Create CAN connection between two Access Points.

Technologies

• Ipaq Bluetooth Stack– Ipaq 3870 has no free Bluetooth stack

development kit. – Upgrading to Windows Mobile 2003 adds a native

Microsoft BT stack that is not supported by the OS.

• ZigBee– Expensive development kit– Low Power– Small transfer rate

What have been done so far?

• Learning to work with the MPLab and the PIC Development Kit

• Learning the Bluetooth Protocol

• Learning the CAN Protocol

• System and application design

• Learning to operate Home Wireless Control project

Schedule

• 10.01.2005 – Finish employing HWC project

• 10.02.2005 – Build the IPAQ controller

• 01.03.2005 – Build the PC controller

• 15.03.2005 – Final report and presentation
