METHOD AND SYSTEM FOR TOUCH SENSOR INTERFACE FAULT DETECTION |
| 摘要 |
A touch sensor interface includes one or more touch detection electrodes whose capacitance increases when touched. A processor converts the increase in capacitance into a change in a counter value. A detector compares the change in the counter value with one or more count thresholds to detect faults in the touch sensor interface. |
