  2. Abstract High speed digital systems laboratory המעבדה למערכות ספרתיות מהירות The goal of this project is to produce A Real-time Data Logging system which connects to a vehicle’s CAN-Bus, An External GPS device and Analog sensors, for reach data storage and analysis. • The device will posses advanced functions such as: • Advanced diagnostic. • Real time monitoring of the vehicle’s operation. • Access and control of other control units on the vehicle. • The device will be able to support various applications and will allow analysis on board a PC. 2

  4. CAN Module CAN Module SPI To MCU MCP2515 Controller MCP2551 Transceiver RX CANH TX CANL High speed digital systems laboratory המעבדה למערכות ספרתיות מהירות • CAN Transceiver – MCP2551 • Transform the TX,RX lines to CAN_H , • CAN_L required for the connector • to the bus. • Supports 1 Mb/s operation • Suitable for 12V and 24V systems • fault-tolerant & high buffering protection • CAN Controller – MCP2515 • Implementing the CAN protocol engine • Receiving and transmitting buffers. • Filtering and masking capabilities for • message analyses and acceptance. • Error detection and handling and bit • timing. 3

  5. Design & Layout High speed digital systems laboratory המעבדה למערכות ספרתיות מהירות Mechanical design was based on a 3D model, designed to fit into and integrate with an exciting platform. 30 boards were sent to manufacture, both the revised PCD platform and the CAN board. 4

  6. System Platform High speed digital systems laboratory המעבדה למערכות ספרתיות מהירות • The CAN project requires a strong platform for power and processing. • we decided to base our CAN project upon the PCD project board The main mechanical design consideration is fitting an additional board into the very crowded PCD package. 4
