1. A method, comprising;
- sampling data from one or a plurality of touch panel sense channels prior to demodulation;
capturing a demodulation waveform, correlated with the sampled data, to form a record;
storing one or a plurality of records; and
accessing the one or a plurality of records to extract diagnostics information.

Abstract
A touch controller with improved diagnostics calibration and communication support includes a data capture register configured to sample data from one or a plurality of touch panel sense channels at an output of an analog to digital (A/D) converter. The sampled data is bit packed, and a demodulation waveform is captured, correlated with the sampled data. The contents of the data capture register, including the sampled data and the demodulation waveform, are transferred to a memory configured to create one or more records from the transferred contents. A processor can be used to extract the one or more records captured in the memory to display to a user for diagnostics or calibration.
