4. Block Diagram

5. Power Supply Schematic

6. Daughter Board Schematic

7. Mother Board Schematic

8. Software section
• MPLAB IDE.
• HI-tech compiler
• PICpgm Programmer (for PIC programming)

9. CAN Process Flow

10. Pseudo code

11. Conclusion:
• Thus we are able to integrate data from
temperature and ultrasonic sensor with real
time clock and transmitting this data into
hyper terminal serially.
• We Achieved successfully loopback mode test
of CAN engine with respect to PIC 18F458.
• Also We successfully done transition of data
from Node I to Node II using CAN bus.

12. Application
• CAN is present and future of following areas:
• CAN In Automobiles: In Automobile industry
where transmission of data transfer in noisy
environment CAN protocol is use. e.g. Automatic
CARS
• CAN in Aerospace: Satellites communication.
• CAN in Motion Control: Industrial machine
Control.
• Other areas: Lift control, Escalators, Telescopes,
Military applications
