2. Introduction Aim of the project Aim of the project Create a cheap wireless control network on household appliances. Part A Part A Create Bluetooth connection between an Access point and an End Point. Part B Part B Create CAN connection between two Access Points.

3. Access Point System Block Design Access Point End Point End Point CAN Connection End Point End Point

4. System Inputs / Outputs Inputs Inputs Household appliances. Outputs Outputs Information from appliances and wireless control over them.

5. Component Specification End Points PIC18F452 is the heart of the End Point. It is cheap, yet powerful enough. PIC18F452 is the heart of the End Point. It is cheap, yet powerful enough. A Bluetooth stack will be implemented upon it to establish connection with an Access Point. A Bluetooth stack will be implemented upon it to establish connection with an Access Point. The Bluetooth connection will be done through a serial port control on a Phillips Bluetooth unit. The Bluetooth connection will be done through a serial port control on a Phillips Bluetooth unit. We will use MPLab to program the PIC chip. We will use MPLab to program the PIC chip.

6. Component Specification – Cont. Access Points Access Points will be implemented with the PIC18F458 because it also supports CAN connection. We will use MPLab and the Phillips Bluetooth unit as well, to contact the End Points. Access Points will be implemented with the PIC18F458 because it also supports CAN connection. We will use MPLab and the Phillips Bluetooth unit as well, to contact the End Points. Extra E 2 PROM memory will be added to store the Access Point’s database. Extra E 2 PROM memory will be added to store the Access Point’s database. To contact End Points available through other access points, we will use a CAN network connection between Access Points. To contact End Points available through other access points, we will use a CAN network connection between Access Points.

7. Work Frequencies The CAN connection maximum transfer rate is 1MB/sec. The CAN connection maximum transfer rate is 1MB/sec. The Bluetooth unit’s maximum transfer rate is 750KB/sec. The Bluetooth unit’s maximum transfer rate is 750KB/sec. The serial connection between the PIC and the Bluetooth unit’s maximum transfer rate is 115KB/sec. The serial connection between the PIC and the Bluetooth unit’s maximum transfer rate is 115KB/sec. Therefore, the CAN connection can support a system with four Access Points, each one transferring one End Point’s data, as expected.
