1. PIC Evaluation & Development Board Project Team Chad Berg – CprE Luke Bishop – CprE Tyson Stichka – EE Nick Veys - CprE Financial Budget Abstract/Background The objective of this project is to produce a PIC evaluation/development board to be used by future ECPE senior design project teams. Many project implementations call for some sort of microcontroller unit in the final product, and this need can often be met by a simple PIC microcontroller. However, the development of a PIC solution is often beyond the expertise and available time of the design team. The board to be produced by this project will enable design teams to quickly and easily develop a PIC for use in their projects. The board will include a wide variety of input and output devices and interfacing ports. It will also be designed to provide a high degree of flexibility, giving future design teams the needed functionality to produce a successful end product. Support a set of PIC microcontrollers that will meet senior design project requirements Provide a flash and CMOS programmer integrated into the system Provide the necessary power supply and frequency source Integrate several input, output, and interfacing components on one board Create a highly modular design that allows the user to select the components to be used Develop supporting software to simplify product development for the user Technical Problem Temperature: 0˚C – 60˚C Humidity: 0 – 90 % No extreme levels of EMI Operating Environment Assumptions Users have an electrical/computer engineering background Users have access to a personal computer with a free parallel port (for PIC programming) Limitations Environmental factors – must function in a normal environment, with no abnormal EMI fields, no water and no extreme temperatures Budget – must be able to build a prototype board with available funds Assumptions/Limitations Milestones All peripheral subsystems designed and tested Board layout completed and all simulations passed Prototype board fabricated Programming environment developed All ASM libraries and sample code written Final product fully operational End-Product Description The end product will be a small, inexpensive evaluation/development board for PIC microcontrollers. Many different peripheral devices will be available along with several different supported microcontrollers to provide solutions for a variety of applications. The board will have sockets for each part to allow ease in swapping parts when one or more have failed. The board will be simple enough that the user will be able to easily understand the layout and be able to develop a microcontroller solution for the current application. Design Constraints Size – board dimensions will not exceed 12”x12” Weight – finished product will weigh less than 3 kg Cost – cost to the end user must be less than $100 Simplicity – layout must be simple enough for end user to understand Functional Requirements Compatible – support for several selected PIC models Versatile – provide solutions for a variety of applications User-friendly – design environment will include several ASM libraries to support devices Well-documented – including tutorials and design guides Technical Approach Design and test the socket(s) and additional circuitry for the microcontroller units Design, prototype, and test the peripheral components and the interface circuitry Complete and simulate board layout using Eagle or a similar tool Develop software libraries to support the board components Testing Approach Design and testing will occur on component-level basis Prototyping will generally occur on solder-less breadboards Each device added to final product only after testing ensures requirements are met Layout will be extensively simulated to ensure it meets operating requirements Sample code will be written to test components of end product http://seniord.ee.iastate.edu/dec0212/ Intended Users & Uses Users Future ECPE senior design teams ECPE undergraduate labs Uses Data acquisition Control Information processing Communications PIC Microcontroller 7-Segment Displays RS-232 Transceiver Ethernet Interface LEDs LCD Display Infrared Interface Matrix Keypad RF Communications Speaker Programmer Temperature Sensors Personnel Effort Dr. Diane Rover Dr. Robert Weber Advisors ECPE Senior Design Client Design Objectives Design Team Dec02-12 Personal Computer
