  1. PIC Evaluation/Development Board Dec02-12 December 10, 2002 Client: ECpE Department Faculty Advisors: Dr. Rover, Dr. Weber Chad Berg, Luke Bishop, Tyson Stichka, Nick Veys

  2. Presentation Outline • Problem Statement • Design Objectives • End-Product Description • Assumptions/Limitations • Project Risks/Concerns • Technical Approach • Evaluation of Project Success • Recommendations for Future Work • Human/Financial Budgets • Lessons Learned • Closing Summary

  3. Problem Statement • Many project implementations require the use of a microcontroller • However, the development of a Peripheral Interface Controller (PIC) solution is often beyond the expertise and available time of the design team

  4. Design Objectives • Design and implement a board to enable future senior design teams to quickly and easily use a PIC solution in their projects • Flexible • Easy to Use • Cost Efficient • Software Libraries

  5. End-Product Description • Microchip 16F876 Based Solution • CAN Interface • Character LCD Display • 7 Segment Displays • Serial (RS232) Interface • Temperature Sensor • Speaker • Software Libraries for All Components

  6. Assumptions/Limitations • Assumptions: • Users have an electrical/computer engineering background • Users have access to a personal computer with a free parallel port • Users have C programming skills • Limitations: • Budget of $100 • Size Constraints • Environmental Constraints

  7. Project Risks/Concerns • Design Error • Over 100 traces and 200 pins • Software depends on working hardware • Device Failure • Socket interfaces were used for crucial components • Loss of a Team Member

  8. Technical Approach • The requirements for this project were relatively open-ended • The 16F876 was chosen for versatility • CAN interface provides interoperability with industrial/automotive equipment • Other devices were chosen for their uses in practical applications

  9. Technical Approach • C was chosen for rapid development • The following libraries were implemented • Character LCD • RS232 • Seven segment displays • CAN • Initialization and diagnostic routine was also created

  10. Technical Approach • Programmer • P16Pro compatible hardware • Parallel port interface • Cheap, reliable • Lots of software support

  11. Technical Approach • Eagle was used for schematic and PCB • Widely used, supported • Simple, powerful interface • Linux/Windows support • Provides schematic capture and PCB layout

  12. Technical Approach • Schematic Capture using custom-made parts • Form logical connections for use in PCB layout

  13. Technical Approach

  14. Technical Approach

  15. Project Success

  16. Further Work • Use the design provided to create even better senior design projects • Additional pins available on the PIC for future expansion • Design is flexible enough to be customized for a particular project

  17. Human Budget

  18. Financial Budget

  19. Lessons Learned • Being a team doesn’t mean doing everything together! • Tasks must be divided between team members to finish on time • Each member must take responsibility for delivering • Communication

  20. Summary • A flexible PIC development solution is important for future senior design students • This design costs half of comparable commercial products • The software libraries provide significant additional value

  21. Q&A
