– Double Tap Delay: The double tap is detected when two taps are performed within the adjusted delay.

The range for the adjusted delay can range between 0s and 1s. The smaller the selected delay is, the

faster the two taps have to be executed.

Approach Detection

Figure 4-6. Approach Detection

Approach Detection is an embedded power-saving feature of Microchip’s Colibri Suite. It sends MGC3140 to Sleep

mode and scans periodically the sensing area to detect the presence of a human hand. Utilizing the built-in

Self Wake-up mode, Approach Detection alternates between Sleep and Scan phase. During the Scan phase, the

approach of a human hand can be detected while very low power is consumed.

A detected approach of a user exceeding configured threshold criteria will alternate the MGC3140 from Self Wake-up

to Processing mode or even the application host in the overall system.
