The entire API is documented - below. In the most general case, to support a sensor there are three steps - you have to follow: - 1) define the main "sn9c102_sensor" structure by setting the basic fields; - 2) write a probing function to be called by the core module when the USB - camera is recognized, then add both the USB ids and the name of that - function to the two corresponding tables in sn9c102_devtable.h; - 3) implement the methods that you want/need (and fill the rest of the main - structure accordingly). - "sn9c102_pas106b.c" is an example of all this stuff. Remember that you do - NOT need to touch the source code of the core module for the things to work - properly, unless you find bugs or flaws in it.
