Capacitive-touch sensing tool offers enhanced updates

The TSS 3.0 is the latest addition to the Xtrinsic touch-sensing software (TSS), which provides added microcontroller functionality without increasing system cost. New features include water tolerance, noise detection, and a touch-detection algorithm for reduced false touches under electrical noise.

With TSS 3.0, the user can define the sensitivity level, or auto-sensitivity calibration (ASC) will do it based on noise level analysis. TSS 3.0 is immune to droplets of water and able to distinguish touch on the electrodes even when the electrodes are covered with a water film.

In addition, the software works with the company’s touch-sensing input (TSI) module, which is embedded into several hardware platforms, to provide better touch detection. The library provides commonly used touch-sensing decoding structures, such as keypad, rotary and slider, to allow upgrades from mechanical to touch-activated interfaces.
