Parts List & Cost

Give a simple list of the cost of your project broken down by components. Do not write long stories here.

Design & Implementation

The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.

Hardware Design

Overview

Interface Board Design

The purpose of the interface board is to provide stable, permanent connection to the SJ2 board. It includes connection to all the components that are necessary for the game to run.

Controller Board Design

The purpose of the controller board is to obtain user feedback to the game. Similar to a real controller, the controller board contains one joystick that can detect five different directions (up, down, left, right, and center). This is used to control movement of the snake in game. Two buttons, confirm(green) and cancel(red) are included on the board so they can be used to select options on the opening screen. An accelerometer, LSM303, is attached to the controller board through female headers for the ease of removal, in the event which the accelerometer needs to be replaced. The controller board also contains an LED to indicate that the board has been supplied of power. The communication between the controller board and the interface board is through and IDC 10-pin header and ribbon cable. The reason why flat ribbon cable is selected is because the crimper, header, and wire for such cable is cheap and readily available.

Hardware Interface

In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.

Software Design

Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.

Implementation

This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.

Testing & Technical Challenges

Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.

Include sub-sections that list out a problem and solution, such as:

<Bug/issue name>

Discuss the issue and resolution.

Conclusion

Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
