The purpose of this project is to reverse engineer the USB protocol controling the Casio EX-F1 high speed camera.

The following camera functionality is currently available:

• Configuration of
• Aperture
• Movie / still mode
• Exposure
• Focus
• ISO
• Frame rate

• Control of
• Shutter
• Movie shutter
• Manual focus
• Zoom
• Live view
• 30/300FPS

Four example projects are provided:

• exf1Ctrl
• Demonstrates the basic usage of the API.

• exf1Hdr
• Demonstrates how to build a simple HDR application.

• exf1Opencv
• Demonstrates the live view functionality and provides an interface to OpenCV.

• exf1Timelapse
• Demonstrates how to build a simple timelapse application.

All projects compile with GCC (using Netbeans) and MSVC (using Visual Studio 2010 express). There are a couple of different ways you can use the compiled binaries:

• Windows
• Using Casio QV Remote Device Driver
1. Using libusb < 1.x.x: Just install libusb win32.
2. Using libusb > 1.x.x: Install libusb win32 and add a filter.
• Using libexf1 driver
1. Just update the driver using device manager.
• Using libusb-1.0 windows backend
1. Install libusb-1.0 windows backend and select WinUSB driver in Zadig.exe.
2. Recompile binaries with LIBUSB_VER set to 1.

• Linux
• Works with libusb-0.1 and libusb-1.0.
1. Tested on Pandaboard ES running Ubuntu.

Please note that the code is developed for the sake of my own hobby projects, but I hope that others will find it useful too. Please use and modify the code at your own risk.
