No problem. I assume you have basic understanding of the hexadecimal and binary represantations of integers. (wikipedia it if you don't.) Firstr step is running mplayer to monitor the results while why change the settings (we keep it running in the backround.) the image is very dark. therfore we lighten it up using the gain on register 0x35: $ echo 0x35 > sensor.address we read the current value in case we need to reset to it afterwards: $ cat sensor.value16 we put in a higher value: $ echo 0x8f00 > sensor.value16 If we like what we see in mplayer we note down: 0x35 - 0x8f00 and move on. If your question referred to all the strange words in the datasheet I can't help you (they are strange to me, too - mostly I google them to get an idea). GWater
