3.8.4 Sensor Drift

The MTCH1030 touch controller provides robust touch sensing under electrical noise. Because touch raw data signals will drift over time, the drift must be compensated. Otherwise, false detections, non-detections and sensitivity shifts over environmental changes may occur.

Drift compensation is performed on the MTCH1030 and no host intervention is needed to compensate for environmental changes.
