Topic: CapSense: how to design scroll wheel ? (Read 1 time) previous topic - next topic



I'm using CapSense and am quite satisfied with results. Now I'd like to create scroll wheel...
It says in CapSense description that :
Scroll Wheels (well, slide pots anyway)

Experiments with a slide pot type linear sensor have been successful with just two pins and a resistance ladder. The basic layout is shown in the Quantum Scrollwheel sensor datasheet.

I cannot find that datasheet or at least couldn't find resistance ladder schematic.

Does anyone have any more information/experience on how to design scrooll wheel or slider with this principle ?

Thanks in advance,
