Is there an effective S/W process to increase responsiveness when hitting the CapSense button multiple times at high speed?

The customer tried to change some of the settings.

Finger threshold

　⇒ Lower

　　(The ON response is faster, but the OFF response is slower.

　　Not very effective.)

Noise threshold

　⇒ Lower

　　(This works by reducing the rise in baseline on Touch.

        Effective.)

Low baseline reset

　⇒ Lower

　　 (Faster resetting after Touch.

         Effective.)

ON debounce

　⇒ Lower

　　(It speeds up the process.

        Effective.)

Filter(median/IIR)

　⇒don't use it.

　  (He didn't feel the effect.)

Hi Inoue-san,

1. Increase the modulation clock frequency.

2. Decrease the resolution of CpaSense.

3. In software do the CapSense scan and call process events APIs as frequently as possible.

Please try above and check once.

Thanks
