/* Initialization code */
SliderParams.id = 1;
SliderParams.type = SLIDER;
SliderParams.channel = 1;
SliderParams.count = 6;
SliderParams.resolution = 2;

Putting It All Together
What type of sensors?
How many channels required?
Single chip or multi-chip design?
Multi-touch support?
Sensor rejection?
