In order to use it, you have to enable i2c-dev +in your kernel. The module i2c-dev is loaded automatically, when you want to +access the /dev/i2c-*-node. + +If your distribution hasn't create the /dev/i2c-*-nodes you can use the +make-i2c-dev-script located its source directory. + +It is not yet completed, but works fine for all dib3000mb-demods (all of the +USB1.1 dibusb-devices are equipped with it). +Having a CSV output would certainly be useful, when you want to make range +tests by driving around with your car and check the signal. Nevertheless, +this isn't written yet, but should be easy-going. Each line then should +have an timestamp. + +I cannot guarantee for the values this program calculates, I'm not a signal +expert, thus I don't know if they are correct. + +Thanks to Amaury Demol from DiBcom, who provides source for showing me how to +calculate frequencies from the demod values. + +Patrick Boettcher + +PS: Please feel free to modify the source to fullfil your wishes. But please +remember, it is released under the GPL, thus please send back patches to the +author or to the linux-dvb mailing list, so other users can have benefit from +it. -- cgit v1.2.3
