Linux Kernel Programming - COP5641

Summer 2005

Florida State University

Project team : Atulya Mahajan, Sean Toh

Goals

Produce a device driver for the Pixel Smart 512-8 gray scale and Video Gala color frame grabber devices.

Desired features

• Integrated support for color and grayscale devices
• Support for dual ported and single ported cards
• Support for interrupt driven I/O
• Streaming I/O
• Implementation of Video4Linux API support

Methodology

• Started from the bare bones driver provided by Dr Baker
• Initial changes to make the module stable
• Incorporated the support for color reads
• Incorporated streaming I/O from the device driver produced in summer 2003
• Added support for color streaming I/O
• Modified read/streaming functionality to work with the interrupt driven cards
• Implemented support for Video4Linux 2 API

Achievements

We achieved almost all of our goals

• Streaming I/O
• Blocking Reads
• Interrupt driven I/O
• Support for V4L
• Support for color cards
• Improvements to the test program
• Additional feature - added one ioctl call to turn the image upside down. In our case at least, we needed that one since our camera was mounted upside down !!

Screen Shots

Grey Scale - 512 X 480

Color - 640 X 480

Video output

A video recording of the video display produced by the driver ( using another camera to record our output !)
