SJSU Cam

Abstract

Our project is a digital camera implemented using the SJONE board. An image is captured using a camera and is then displayed on an LCD screen. An SD card is also used to store the output of the camera as the captured image. For navigating through various options on the LCD screen, a menu is created.

The camera is mounted on a 3D printed box which contains an LCD screen behind to display the image being captured by the camera.

Objectives & Introduction

The objective for this project was to learn how timing and buffer play an important role in capturing the pixels from the camera and displaying them on the LCD screen. The following objectives were set for the project: 1. Integrate a camera (mention what kind of camera ), which has a better rate of capturing the image with the SJONE board. 2. Integrate the LCD board by choosing the right resolution. 3. Have a menu implemented for the options available on the digital camera.

Schedule

Show a simple table or figures that show your scheduled as planned before you started working on the project. Then in another table column, write down the actual schedule so that readers can see the planned vs. actual goals. The point of the schedule is for readers to assess how to pace themselves if they are doing a similar project.

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

Discuss your hardware design here. Show detailed schematics, and the interface here.

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

The camera is interfaced to the board through SPI communication protocol. The raw pixels are read from the camera to the SJONE board. There are five buttons on the camera. One of them used to capture an image and store it on the SD card. The LCD screen is interfaced again through SPI communication protocol. The raw pixels received from the camera are displayed on to the LCD screen.

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?

Acknowledgement

We would like to thank our professor, Preetpal Kang for designing such a course where learning was his guidance and consistent feedback. We would also like to thank the ISA team for their valuable inputs as per their own experience of the course when taken and their support and motivation at every phase of this project. There were some unsung, selfless classmates who helped us whenever necessary, whenever any immediate hardware was required or any other guidance needed in spite of being from the rival teams. We would like to thank each one of them who forgot their differences or considered the course and project as a competition to selflessly help us when in need.
