Figure 16.

Double click recognition

In Figure 16(a) the double click event has been correctly recognized, while in Figure 16(b)

the interrupt has not been generated because the input acceleration exceeds the threshold

after the window interval has expired.

TAP_CFG description

Enable interrupt double tap-tap on Z axis. Default value: 0

(0: disable interrupt request; 1: enable interrupt request on measured accel. value

higher than preset threshold)

Enable interrupt single tap-tap on Z axis. Default value: 0

(0: disable interrupt request; 1: enable interrupt request on measured accel. value

higher than preset threshold)

Enable interrupt double tap-tap on Y axis. Default value: 0

(0: disable interrupt request; 1: enable interrupt request on measured accel. value

higher than preset threshold)

Enable interrupt single tap-tap on Y axis. Default value: 0

(0: disable interrupt request; 1: enable interrupt request on measured accel. value

higher than preset threshold)
