This is sample driver-code for dos/windows.

IIRC this is the Windows driver source.

This is the latest release of the linux driver.

This is a python-gtk application to write strings to the
/proc-filesystem to control the camera.

Best start with the pp_test.zip and get the chip-description to
implement a minimal driver. Especially the windows- and the
linux-driver do much more and have additional levels of abstractions
that you might not need for your microcontroller.
