Question: Does the raw count of a sensor change over a period of time?
Raw count is a function of the capacitance of the sensor, reference voltage, external bleed resistance (for CSD-Rb), internal IDAC (for CSD-IDAC), and IMO. Environmental conditions such as temperature and humidity can vary over time and affect these values. Therefore, raw counts can change over time. However, these changes are gradual, and the baseline update algorithm assures that they do not result in false touches being reported.
