9.4 Touch Response Time
Response time is the time required for the touch surface to respond to a finger touch event. This includes the time taken by the microcontroller to perform touch data acquisition on the surface sensor nodes and the post-processing of the acquired data to report a valid touch event. The number of touch events reported per second increases with lower response time.
| Serial Number | Touch Measurement Periodicity | Detect Integrator | Time Taken for One Measurement | Touch Response Time |
|---|---|---|---|---|
| 1 | 20 ms | 2 | 1.7 ms | 5.1 ms |
Note: The touch response time varies according to the Detect Integrator (DI) setting. To
achieve optimum response time and touch sensitivity, the DI parameter needs to be
adjusted according to the sensor design.
